Last year AMD released their Northern Islands architecture starting with the Barts graphics processors, which was then followed by the Cayman architecture. These Northern Islands graphics cards have since become an extremely successful series, but the product range as we know it was an adaption on AMD's part to compensate for TSMC cancelling their 32nm process in favor of its 28nm technology. This forced AMD to release a second generation of 40nm parts. Though those issues are behind AMD now, as its Southern Islands architecture finally is among us, bringing with it the first 28nm GPU codenamed Tahiti. The first AMD graphics board to utilize this new architecture is the high-end Radeon HD 7970 launched today. - NeoSeeker
Based in Hong Kong, Zotac has been around since 2006 and entered the market with an expanded lineup of NVIDIA powered graphics cards, which includes their passive cooled Zone editions and the class leading overclocked AMP! editions, in addition to the standard GeForce series lineup. They have tried to bring the latest DirectX 11 technology to rather every price point with the current king of the hill being the GeForce GTX 590 currently priced at $749 shipped down to the entry level GeForce GTX 550 Ti series. Doing so they got a wide range of products which will please almost everyone, and with their AMP! version being designed with these overclockers in mind given them an extra boost in performance. - LegitReviews
It has been a while since the last release, but today we bring you a new version of our favorite NiBiTor software which is the original GeForce series BIOS tweaker software, providing support for the latest NVIDIA graphics cards. With NiBiTor we provide graphics card enthusiasts or hardcore overclockers full control over some advanced features and functionality found on firmware of supported cards. And by doing so users can gain some extra performance, enable certain hidden features, tweak memory timings, access device related information, adapt bootup settings, change fan speed options and even get extra stability using their NVIDIA based graphics accelerators which will just give them that little extra value. - mvkTech
AMD's Radeon HD 6450 has been on the market for almost two months now. It is the slowest, cheapest and entry-level Radeon HD 6000 series card. When it was launched, AMD provided Radeon HD 6450 samples to the press which used GDDR5 memory clocked at 3600MHz effective. And when looking at the current market, we only see Radeon HD 6450 variants using GDDR3 memory, instead of the faster, more expensive GDDR5. That's why we decided to take a look at such version to provide a more clear picture of these entry level graphics card market. Sapphire's Radeon HD 6450 uses a completely passive low profile design, which makes it an excellent choice for a low noise office system. - techPowerUp
It has been a few months since these AMD Radeon HD 6990 graphics card initially launched. Since that time, a number of AMD's board partners have launched their own Radeon HD 6990 cards, though as is typically the case with these first wave of products based on a new GPU, they all conform to AMD's reference design, save for a water cooled card from PowerColor. While most of the Radeon HD 6990 cards on the market today are fundamentally very similar, we thought it would be a good idea to check out a retail version using the latest drivers to see how well the card performs with updated software. To that end, we got an HIS Radeon HD 6990 card and will see how things sake out in a handful of games. - HotHardware
We've looked at the HIS Radeon HD 6970 Turbo, we've also looked at some IceQ variants of these Radeon HD 6800 series, but today the power of the IceQ and Turbo series combine to create the HIS Radeon HD 6970 IceQ Turbo. The IceQ series is a popular one for HIS and has always represented their best cooler in the line-up. Combined with the Turbo label, the card carries with it also a nice out of the box overclock. Today though, we have decided to ignore the overclock and instead make use of the cooler and overclock the card ourselves. The main focus is really on the cooling solution that should be superior compared to others, and would therefore hold higher overclocking potential as extra feature. - TweakTown
To help fill a model gap that no one told us about, NVIDIA has just released its GeForce GTX 560, a slight step down from their Ti variant. Featuring a cut of 48 cores and the potential for wildly varying clock speeds, this graphics card is an strange beast. But, we look to pit MSI's Twin Frozr version against our usual fleet of cards to see where it stacks up in the end. Didn't think that it was possible to push another model into NVIDIA's mid-range? Well, the company has proven you wrong, with the help of its GeForce GTX 560. As it appears, these GeForce GTX 560 cards, like its older brother is set to see multiple releases, to help fine tune the choices as well as can be to help precisely match your budget. - Techgage
We are not sure what word we would use to describe what came to mind when we heard that Sapphire was going to be re-releasing the Radeon HD 5850 and Radeon HD 5830 to the market. First we wondered, why? But the answer to that would be nothing more than excess cores that need to go. Next, we were a bit surprised and shocked because we felt it was more of a step backwards than anything else. The thing is though, if the price and performance is good, why not buy one? Both models were very good over 12 months ago, but the Radeon HD 5830 never sold. People didn't like the naming scheme and it was simply never really accepted. And being so, why would it be accepted this time? - TweakTown
Last October, AMD launched the first cards in their Radeon HD 6800 series. And in the six months since then we've seen the release of the top end Radeon HD 6970 and Radeon HD 6990 cards which are targeted at serious gamers. But until now, those looking for a budget offering have had to revert back onto the previous generation Radeon HD 5800 series. Today we are going to look at the new AMD Radeon HD 6670 graphics card which is designed for people who want to improve the media capabilities of their machine and perhaps just engage in some casual gaming. AMD have also included EyeFinity support on these cards, meaning it is perfect for those who want a multi-screen setup at a lower budget. - KitGuru
Originally released back in 2009, these AMD Radeon HD 5800 graphics series quickly gained popularity due to their ability to fully support DirectX 11, providing a completely new level of tessellation. Released in October, the Radeon HD 5850 cards filled the lower end of the performance slot and was able to deliver great performance for its price. Originally, this Radeon HD 5850 was oriented towards users who wanted that extra punch, but didn't feel the need to go overboard with their graphics. However, for those that wish to take full advantage of the Radeon HD 5850, CrossFire is available, and considering the low price of the video cards, this should be easily accessible and set you again as top performer. - Bjorn3D
That's right, we are back with a new version of our favorite NiBiTor software which is the original GeForce series BIOS tweaking software, providing support for the latest NVIDIA graphics cards and is updated on a regular basis. With NiBiTor we provide graphics card enthusiasts or hardcore overclockers full control over some advanced features and functionality found on firmware of supported cards.
