SAPPHIRE RADEON HD 4890 VAPOR X REVIEW AT AMD ZONE - "Sapphire's Vapor-X line has been around now for some time and is Sapphire's custom heatsink and fan combination. It runs quieter than the standard heatsink and also should allow for better overclocking. Our model came pre-overclocked with a core of 875MHz (25Mhz more than normal) and 1GB of GDDR5 running at 1050Mhz (75MHz above the standard clock). It also is a very slick design and on Sapphire's blue PCB as opposed to ATI red. It is a very aesthetically pleasing card and a lot of that also has quite a bit of function such as the ramsinks covering all the memory modules."

ASUS RADEON HD 4770 REVIEW AT BJORN3D - "A GPU in the $100 price range isn't expected to pack high dollar punch, but it is nice to find one that packs a good price performance ratio. Your probably not going to run high end games at maximum settings, but you will be able to run most games at an acceptable level with a few compromises in game settings. Cards like the Asus EAH4770 are mainstream GPU's that give you the basic performance you need for productivity, and pack enough punch to let you game in the price range that won't break the bank."

XFX RADEON HD 4770 REVIEW AT MOTHERBOARD.ORG - "Recently, ATI launched their RV740 chip which is their mainstream version of their HD 4890 card. This is the card ATI targets for the $110 MSRP price range and is the replacement for the HD 4670 card. The HD 4770 is ATI's first 40 nanometer chip and should offer excellent performance for the price. XFX has released two versions of the HD 4770, one with the standard reference cooler and another with a heatsink/heatpipe/fan cooler. Today's review is on the HD 4770-YDFC card, which has the standard fan and heatsink."

MSI RADEON HD 4770 REVIEW AT MOTHERBOARD.ORG - "ATI launched the Radeon HD 4770 last month to a lot of fanfare for a video card that performs near the level of its bigger brother the HD 4870 with a price point of around $99 online. This card seems to pave the way with high performance and great feature sets that can't be met by NVIDIA's solution. ATI has delivered in a big way, outstripping the intended competition and bringing the first 45 nanometer process video cards to the desktop market, just like they were the first to deliver the first 40 nanometer mobile parts. Today's review is on the MSI R4770 T2D512 video card, the latest card from MSI."

SPARKLE CALIBRE 9800 GTX+ REVIEW AT TECHWARE LABS - "TechwareLabs takes a look at the Calibre 9800GTX+ video card which promises a good gaming experience with a design that keeps it cool. We compare the card against another high end solution from ATI to find out if this budget card can keep up with the big dogs. Read our review to find out."

MSI GEFORCE N260GTX LIGHTNING REVIEW AT GURU3D - "MSI has released two new GeForce GTX 260 video cards. The first one being the MSI N260GTX Lightning, and the second one a N260GTX Lightning Black Edition. Perhaps you guys remember it, but both products where already showcased at CeBit this year. These are probably the most feature rich GeForce GTX 260 videocards you can find on the web. First off, MSI N260GTX Lightning has twice the standard GeForce GTX 260 GDDR3 memory summing up to an incredible 1792 MB, and then utilizes a Twin Frozr cooling with heatpipes, dual slot heatsink and two big fans. The card design is Phase PWM, with 8 phases are reserved for the GPU and 2 phases for the memory. Furthermore, this graphics card has important overclocking features like V-Check points to measure the voltage."

MSI N260GTX LIGHTNING BLACK EDITION REVIEW AT MOTHERBOARD.ORG - "MSI manufactures motherboards, video cards and other computer related equipment. They are a Tier-1 motherboard manufacturer that manufactures video cards based upon both ATI and NVIDIA video chipsets. Today they are launching the N260GTX Lightning Black Edition video card. This card has an array of new features that will improve performance versus the standard clocked video card including dual fans, a new overclocking mechanism and more."

INNO3D ICHILL GTX275 REVIEW AT OCC - "When looking for a video card that is capable of playing games well at high quality, users are bombarded with choices: brands, versions, overclocked and stock speeds, and many other variables. The recently released GTX 275 is intended to fill the price and performance gap between the GTX 260 and GTX 285/295, and also combat AMD’s new 4890, all the while still offering high-end performance. Up for review is Inno3D’s iChill GTX 275 with a non-reference cooler designed by Arctic Cooling. The card comes with 896MB of GDDR3 clocked at 2350MHz, the core running at 670MHz, and shaders at 1474MHz, all on a 55nm fabrication process with 240 stream processors. Overall, the card matches specifications of a GTX 280/285 and half of a GTX 295 on stream processors, and matches a GTX 260 and GTX 295 with 896MB of memory."

POWERCOLOR RADEON HD 4890 LCS REVIEW AT HOT HARDWARE - "PowerColor's HD 4890 LCS offers respectable speed increases over reference design cards. With an extra 50MHz for the core and a memory frequency raised by 25MHz, we definitely don't expect outrageous gains. Rather, we anticipate a measurable boost in performance coupled with the inherent advantages of watercooled parts. But before we check out the benchmarks, we'll inspect the card and its accessory bundle."

ATI RADEON HD 4890 VS NVIDIA GEFORCE GTX 275 REVIEW AT TECH SPOT - "As luck would have it, the GeForce GTX 275 was not just a quick and easy counter for the Radeon HD 4890, it was the perfect counter. Prior to the launch of these two cards the Radeon HD 4870 and GeForce GTX 260 were already doing battle. The Radeon HD 4890 was meant to outclass both products and conquer the $250 price range but evidently that didn't go as planned."

SAPPHIRE RADEON HD 4770 REVIEW AT AMD ZONE - "The Sapphire card we're loooking at isn't overclocked and doesn't deviate too far from the standard spec. In case you're not up to speed on the Radeon HD 4770's specs the card features 640 stream processors, which is similar to the Radeon HD 4830 but has 512MB of GDDR5 like the Radeon 4870 and Radeon 4890. We'll see how this performs later on in benchmarks."

ASROCK M3A790GXH 128M MOTHERBOARD REVIEW AT AMD ZONE - "Although one doesn't have to upgrade from the Socket AM2+ motherboards for AMD's new AM3 processors to work if you're starting fresh going with a Socket AM3 based motherboard is probably the better way to go in the long run as DDR2 production ramps down prices are already starting to increase while DDR3 prices decrease. Today we'll be taking a look at a new AM3 board from ASRock, the M3A790GXH/128M."

DIAMOND RADEON HD 4770 REVIEW AT OCC - "Today I'll be looking at ATI's new HD 4770, which will be competing against the Nvidia GTS 250/9800GTX+. So what's so special about this card? Well, for one thing, it's using a 40nm process; this means lower power requirements and less heat...hopefully!"

SAPPHIRE RADEON HD 4770 REVIEW AT ELITE - "Of course, basically repeating the exact same review all over again would be both dull and pointless, so for this article we've spiced things up a little by combining the power of two Radeon HD 4770 boards in a CrossFire multi-GPU configuration. Interestingly, in cost terms this brings a pair of Radeon HD 4770 parts into almost exactly the same price bracket as (if not cheaper than) a single Radeon HD 4890 1GB, which makes for a potentially interesting match-up in its own right. So which is better - Two Radeon HD 4770 512MB boards in CrossFire, or a single Radeon HD 4890 1GB? There's only one way to find out."

SONY CYBER-SHOT W290 DIGITAL CAMERA REVIEW AT HARDWARE SECRETS - "Over the years the Sony Cyber-shot digital camera has been a popular point-and-shoot camera, so when they announced a new Cyber-shot with a Carl Zeiss 5x optical zoom wide (28mm) lens that takes photos at 12.1 megapixels and shoots 720p HD video, we just had to take a look."

ATI RADEON HD 4770 REVIEW AT TECH REPORT - "This latest Radeon is the world's first 40nm GPU and a budget wonder. We've explored its performance in new games from different genres, with an eye toward the GPU makers' special sauces: DirectX 10.1 and PhysX."

ASUS RADEON HD 4770 REVIEW AT PC STATS - "AMD is making a new addition to its midrange graphics card lineup today with the introduction of the Radeon HD 4770 videocard, based on the companies first 40nm GPU, the RV740. The Radeon HD 4770 strikes a balance between performance and price, coming just under the lucrative $100 mark and slotting in nicely in terms of performance between existing Radeon 4670 and 4850 videocards. "

ATI RADEON HD 4770 REVIEW AT HARDOCP - "Cheap price, low power, and an enjoyable gameplay experience, all of this is possible in AMD’s new Radeon HD 4770 launching today. We will take the HD 4770 for a spin in six games and compare it to a NVIDIA GeForce GTS 250. You’ll be surprised at the level of gameplay possible for around $100 these days."

ATI RADEON HD 4770 REVIEW AT HOT HARDWARE - "You see, the brand new Radeon HD 4770 is AMD's first mainstream desktop GPU manufactured using a 40nm process, and as such, it is more economical for the company to produce (with a smaller die size) and it consumes little power relative to the current crop of products manufactured at 55nm. The Radeon HD 4770's main features don't stray far from the other members of the Radeon HD 4000 family, but its specifications are somewhat different due to the use of a new GPU, which was formerly codenamed RV740."

ATI RADEON HD 4770 REVIEW AT LEGIT REVIEWS - "AMD is launching the World's first 40nm graphics card today with the introduction of the ATI Radeon HD 4770. With such a small die size, it means that AMD can fit more dies per wafer and reduce costs. AMD expects that the Radeon HD 4770 should sell for $109 with an available rebate of $10, which brings the final price into the uber sexy sub-$100 category. Usually the sub-$100 category means crappy performance, but with a core clock of 750MHz and 512MB of GDDR5 memory you might want to think twice about that."

ATI RADEON HD 4770 REVIEW AT TECH POWERUP - "Today AMD releases the first 40 nm GPU in the world. Their new RV740 graphics processor powers the HD 4770 Series which is targeted at the sub-$100 segment. Rather than focusing on a small volume in high-end graphics, AMD has realized that a lot of people want cheap, affordable graphics that still can play most games out today. RV740 is heavily based on Radeon HD 4850/4870/4890 technology. For example we are seeing GDDR5 memory on the card. Since RV740 comes only with a 128-bit memory bus interface, GDDR5 can show huge improvements because it effectively doubles the memory bandwidth. So RV740 with 128-bit GDDR5 has the same bandwidth as 256-bit RV770 with GDDR3 (HD 4850)."

ATI RADEON HD 4770 REVIEW AT AMD ZONE - "The video card wars between ATI and Nvidia have been very hot lately with the most recent exchange a couple of weeks ago with the Radeon 4890 and GTX 275. That said even though those GPUs are a bargain at just over $200 AMD have been paying attention and realize that the market with the most growth is the $100 market where their next attack lines with the Radeon HD 4770 which is released today and we'll be taking a look at."

ATI RADEON HD 4770 REVIEW AT ANANDTECH - "With 826 Million transistors, the RV740 GPU that powers the Radeon HD 4770 features a native 640 SP (128 five-wide vector units arranged in 8 SIMD cores) as opposed to the 640 cut-down-from-800 SP 4830. Among the other differences is the fact that the 4770 hooks into GDDR5 over a 128-bit memory bus at almost the same clock speed (producing just a little bit less bandwidth at half the pinout)."

ATI RADEON HD 4770 REVIEW AT GURU3D - "RV740 is the replacement of the RV730 (Radeon HD 4650/4670), that product line will still remain in the market for a while, yet we think RV740 in time will replace it completely as this series is just too strong. Why you ask? Well, the RV740 is really a disciple of RV770, yes indeed... the Radeon HD 4850/4870."

ATI RADEON HD 4770 REVIEW AT THG - "Enter ATI’s new Radeon HD 4770—the first GPU manufactured on a 40 nm process. As with the other models in the company’s HD 4000-series family, the HD 4770 is derived from the same popular RV770 design popularized by the Radeon HD 4870 and 4850 cards almost a year ago."

XFX GEFORCE GTS 250 REVIEW AT MOTHERBOARD.ORG - "NVIDIA's (and ATI's for that matter) naming schemes for their video cards has gotten very convoluted. The GeForce 8800GT/8800GS/9600GSO/9800GT/9800GTX/9800GTX+/9800GX2 all use the same core chip with a few modifications in terms of the clock speeds and SPs. The 9800GX2 is a special case due to it being two G92 chips on a single graphics card but functionally it is the same chip. NVIDIA wants to differentiate their naming scheme by having GTX stand for the enthusiast cards, GTS for the mainstream and GT for the lower end. The number following the prefix indicates the performance with higher numbers meaning higher performance. For example, the GeForce GTX 280 is faster than the GTX 260 216 core."

AMD PHENOM II X4 955 PROCESSOR REVIEW AT TECH REPORT - "With the introduction of the Phenom II X4 955 Black Edition, AMD matches its world record for longest CPU name. Even better, this is the fastest desktop CPU the company has ever produced, and it goes toe to toe with one of Intel's best Core 2 Quad processors."

OPTERONS TO HAVE 12 TO 16 CORES AT TECH REPORT - "To coincide with the original Opteron processor's sixth anniversary, AMD showed the latest version of its server roadmap to the press earlier this afternoon. Among other revelations, the company said its 12-core Magny-Cours processors will launch in the first quarter of 2010. A 16-core, 32nm successor based on the next-gen Bulldozer architecture will follow in 2011, as well."

AMD PHENOM II X4 955 REVIEW AT AMD ZONE - "Although they seem still quite fresh, AMD's Socket AM3 Phenom II processors have been on the market now for two and a half months and although the Phenom II X4 810 hasn't been too spectacular the Phenom II X3 720 BE has been a hit with a higher default clockspeed and an unlocked multiplier at a great price. However, at the high-end AMD still has had the Phenom II X4 940 Socket AM2+ processor at the top running at 3GHz. That is until now as AMD now has a Socket AM3 processor as their flagship platform, the AMD Phenom II X4 955."

BFG GEFORCE GTX 275 OC REVIEW AT BJORN3D - "The advantage of buying a BFG factory overclocked GPU is that you get that little extra performance boost and it's covered by the limited lifetime warranty. Many people want the performance boost but don't have the experience or patience to overclock the GPU, so factory overclocked is good for them and it keeps the warranty intact. Not only do we have the BFG GTX-275 for you today, we also threw in some GTX-275 SLI results. So sit back and relax while we drive the GTX-275 like it was meant to be driven as hard as it will go, then pair it up with another GTX-275 and drive a pair of the enthusiast GPU's like wild horses running from a prairie fire."

INNO3D GEFORCE 275 GTX REVIEW AT LEGION HARDWARE - "Today we are taking a look at a new graphics card from Inno3D that is designed to deliver high-end performance at an affordable price tag. Based on the GeForce GTX 275 reference design, this new Inno3D product features overclocked core and memory frequencies for even greater performance."

GALAXY GEFORCE GTX 275 OC REVIEW AT TWEAKTOWN - "Today we'll see if Galaxy can make the gap between the HD 4890 and GTX 275 even larger with the help of an increase in clock speeds. So, let's have a quick look at the package before we take a closer look at the card along with its cooler."

NEW ATI CATALYST v9.4 DRIVER AT ATI/AMD - "New Features - ATI Catalyst™ 9.4 - ATI Catalyst 9.4 includes a new ATI Overdrive™ auto-tune application to accurately determine the best over-clocked engine and memory values for ATI Overdrive supported ATI Radeon™ Graphics accelerators. Designed for the ATI Radeon™ HD 4000 Series."

ATI RADEON HD 4890 VS NVIDIA GEFORCE GTX 275 AT TECH REPORT - "In the Radeon HD 4890, AMD's new GPU silicon resets the single-chip performance plateau at about 250 bucks. Nvidia's GeForce GTX 275 has shown up abruptly, as well, determined to crash the party. Will the neighbors call the cops before things get out of hand?"

ZOTAC GEFORCE GTX 275 AT TRUSTED REVIEWS - "I was tempted to start this review with a full-blown rant about why it is that two manufacturers chose to launch their new products on the same day, giving me very little time to test and evaluate them. However, that's probably just my grouchy state from having been up until 4am last night doing the testing. The fact of the matter is, you don't care, and that's cool, I totally understand; both nVidia and AMD have released brand new graphics cards and all you want to know is which one to buy. So, yesterday I looked at AMD's ATI Radeon HD 4890 and now it's the turn of nVidia's GeForce GTX 275 or in our particular case Zotac's overclocked version thereof."

GIGABYTE RADEON HD 4890 REVIEW AT TWEAKTOWN - "The HD 4890 is an interesting card. We haven't heard loads about it and the general excitement about the card is quite low. But the main reason we think people aren't that excited about the card is because both they and we know that the card isn't going to be as fast as the dual GPU wielding GTX 295. And this is what most people want, especially when the HD 4800 series of ATI cards have been out for so long."

ATI RADEON HD 4890 VS GEFORCE GTX 275 AT ANANDTECH - "Now we know that both the Radeon HD 4890 and the GeForce GTX 275 will be priced at $250. This has historically been sweet spot of a price point, offering a good balance of performance and cost before we start to see hugely diminishing returns on our investments. What we hope for here is a significant performance bump from the GTX 260 core 216 and Radeon HD 4870 1GB class of performance. We'll wait till we get to the benchmarks to reveal if that's what we actually get and whether we should just stick with what's good enough."

ATI RADEON HD 4890 REVIEW AT GURU3D - "ATI today unleashes not one, but two new SKU's based on the Radeon HD 4890. The Radeon HD 4890 is their new most high-end single GPU based graphics card. It is not a 40nm product as many of you had heard and hoped. It is however an incremental update of the Radeon HD 4870. Features wise 100% the same product, yet made more power efficient in idle, performs faster and is being repositioned as an enthusiast product .. a very tweakable and overclockable piece of machinery actually."

ATI RADEON HD 4890 VS GEFORCE GTX 275 AT FIRING SQUAD - "Together, these two new GPUs encompass the last hurrah for the DirectX 10 era of gaming. Later this year we’ll see the debut of the first DirectX 11 cards from ATI and NVIDIA. Presumably these next-generation cards will deliver higher performance, but they probably won’t be cheap either. With today’s GeForce GTX 275 and Radeon 4890 launch, ATI and NVIDIA are aiming for the price/performance sweet spot of the market. Both GPUs are being offered at or below $250. Let’s see how they compare to one another."

ATI RADEON HD 4890 VS GEFORCE GTX 275 AT EXTREMETECH - "It used to be common for graphics cards to go through what we would call a "spring refresh" period. New products would hit the market that use new chips based on the same architecture of the chips released in the previous Fall. The new chips would have a few simple changes designed mostly to juice-up clock speeds, or to bring a high-end chip down to a more affordable level, offering more bang for the buck."

ATI RADEON HD 4890 REVIEW AT TECHWARELABS - "Today we check out the lastest weapon in the ATI arsenal, the 4890. Breathing new life into the 4800 line along with a few new tricks the 4890 delivers more performance and at a lower cost. We compare the new 4890 against the former flagship the 4870 as well as against its intended rival the GTX 260. Find out how well the 4890 stands up in our tests."

ATI RADEON HD 4890 1GB REVIEW AT AMDZONE - "It has been a little while since ATI launched a new video card after the onslaught of new graphics cards last year which brought back very healthy competition into the graphics market and helped AMD steal the scene from Nvidia. While Nvidia has launched some new cards most of them are nothing more than re-brandings which doesn't exactly make for an exciting launch. ATI's 4870 X2 was launched all the way back in August and the 4870 in June. While the transition to 40nm is taking a little longer for both ATI and Nvidia, the 55nm manufacturing process has come a long way since last summer and is now much more perfected. In essence, this is what we have with ATI's new GPU, the Radeon 4890 HD, launching today."

ATI RADEON HD 4890 VS GEFORCE GTX 275 AT PC PERSPECTIVE - "Rumors of the existence of RV790 had been swirling for some months and even our own Josh Walrath hypothesized what AMD was planning to do with the slightly updated GPU. Some people sided with improved shaders units while others said it was a clock rate increase only. It turns out both parties had it slightly off – the RV790 does in fact clock a lot higher thanks to some minor architecture changes and packaging adjustments."

ATI RADEON HD 4890 REVIEW AT HARDOCP - "AMD's new Radeon HD 4890 launches today and we've got it covered with a good [H] look at the ASUS EAH4890. We've got a great evaluation for you guys today, comparisons with the GTX 280, HD 4870 1GB and the new GeForce GTX 275. You guys won’t be disappointed, 1GHz GPU possible?"
