AMD Radeon HD 7970 review

AMD Radeon 7970

The perpetual war for supremacy between AMD and Nvidia constantly leaves enthusiasts dodging shrapnel: When you want the best video card you can afford, why buy one now instead of waiting for the better one the competing chipset designer will undoubtedly release in a few months? This leaves reviewers in a tough spot, too, as we're constantly proclaiming that nearly every new card is the fastest ever. But because you can only live in the world you live in, we're obliged to go there. So, here goes once again: The just-released AMD Radeon HD 7970 ($549 list) is the latest fastest and most feature-rich single-GPU card ever, surpassing our previous Editors' Choice winner, the Nvidia GeForce GTX 580.

Though we have little doubt that Nvidia will yank back that title with its next generation of cards, the 7970 is an impressive achievement for the moment.  (It's rumored to become widely available by early January of 2012.)  The inaugural member of the Southern Islands family, it utilizes a fresh architecture AMD refers to as "Graphics Core Next." Based on a new 28nm process technology and utilizing more than 4.3 billion transistors, Graphics Core Next uses a revised instruction set architecture, gives each compute unit the ability to simultaneously execute instructions from multiple kernels, and delivers an increased number of instructions per clock cycle per square millimeter of GPU space. The result, so AMD claims, is "designed for high utilization, high throughput, and multitasking."

AMD releases $150 Radeon HD 6790 video card

Posted by Andru Edwards Categories: PC / Laptop

Radeon HD 6790

AMD announced today that it has released the new Radeon HD 6790 video card, priced at $149 and thus in direct competition with Nvidia's recently released (and same-priced) GeForce GTX 550 Ti.

The Radeon HD 6790 is positioned between the upper-end-mainstream Radeon HD 6770 and the lower-end-enthusiast Radeon HD 6850, intended for users running at midrange resolutions (such as 1,680-by-1,050) and detail settings. The card offers 1.34 teraflops of compute power; has a core clock speed of 840 MHz, 800 stream processors, 40 texture units, and 16 ROPs; and is loaded with 1GB of GDDR5 frame buffer, operating at 4.2 Gbps on a 256-bit memory path.

AMD's press materials for the 6790 identify the 6790's TDP as about 150 watts—more than the 6850, and approximately in the same league as the card above that one, the Radeon HD 6870 (151 watts). AMD's reference spec for the card suggests it will require two six-pin connectors from a power supply, though the company says that some models will be available using only one.

RAdeon had 6990

For gamers and enthusiasts who aren't willing to settle for just an ordinary video card—you know, the kind with only one GPU—the Radeon HD 6990, which AMD is releasing today, could be the next must-have product.

As the 6000-series replacement for 2009's ATI Radeon HD 5970, the 6990 boasts a pair of powerful graphics processing units (GPUs), and some of the speediest specs on the market: compute power of 5.1 teraflops, a core clock speed of 830 MHz, 3,072 stream processors, 192 texture units, 64 ROPs, and 4GB of GDDR5 frame buffer running a long a 5-Gbps, 256-bit memory path. For adventurous users who want even faster frame rates, a switch on the card itself can automatically overclock the card to still-higher levels of performance.

CES 2008 Video: AMD Spider platform, Dual-Chip Radeon R870

We take a few moments with ‘s Rick Bergman, General Manager of the Graphics Processing Group, about their new Spider platform—a three-tiered computing system that helps tie together and ensure compatibility between the chipset, CPU and GPU. We talk about what sort of benefits this means to the enthusiast-class consumer. We also dive into the nitty-gritty with the new , currently codenamed the R870—a dual chip design that has two separate GPU units with an internal Crossfire link and Alternate-Frame Rendering to tie them together. I also ask about some of the design challenges realized in smashing two cards together and getting an efficient, workable result. The design is impressive and the ability to link two of these cards together will come to mean a great deal of graphics processing power in the near future.

The card will be available late January and can be powered in a typical system by a 500 watt power supply; has cut their power requirements for similarly powered cards in half, without sacrificing any performance.
