AMD RADEON HD 6950 SERIES
Max board power is 250W for the 6970 and 200W for the 6950, and both have the same digital video output configuration.AMD has released today the new Radeon HD 6900 Series with the Radeon HD 6970 and Radeon HD 6950. That puts memory bandwidth in the 175GB/s and 160GB/s ranges for the Radeon HD 69, respectively, which is a big step up from the 153GB/s of the 5870. The memory speed on the 6970 tops out at 5.5Gbps (1375MHz), while the 6950 hums along at 5.0Gbps (1250MHz). Both cards are also outfitted with 2GB of GDDR5 memory that utilize a 256-bit interface. The Radon HD 6970 sports 96 texture units while the 6950 offers 88 (up from 80 in the 5870) and each has 32 ROPs. The 6970's GPU is clocked at 880MHz and the 6950's at 800MHz. Well, the answer to that question lies in AMD's new "VLIW4" architecture, which we’ll explain a little later.ĭisregarding the shader counts for a moment, you can see the Radeon HD 6970 offers compute performance in the neighborhood of 2.7TFLOPs (single precisions) and 675GFLOPs (double-precision) and the Radeon HD 6950 offers 2.25TFLOPs / 564GFLOPs.
AMD RADEON HD 6950 UPGRADE
If the Radeon HD 6970 is supposed to be an upgrade over the 5870, why does it have a lower total number of stream processors? The Radeon HD 69 ALUs versus 1600 in the Radeon HD 5870, and the 6950 has “only” 1408 ALUs. We suspect that those specifications may leave some of you scratching your heads, though. Then we’ll dive into the particulars and check out their performance.Īs you can see in the two images above, the new Radeon HD 69 look virtually identical from the front, save for their model number decals. Take a moment to peruse the specs and soak up the first couple of pics of the new Radeon HD 6900 series cards below.

And wouldn’t you know it we have a pair of each in house and have been testing them with a completely revamped test-bed for a few days now.

Initially, the Cayman GPU will power two graphics cards, the Radeon HD 6970 and the Radeon HD 6950. Because of this, Cayman is actually the largest graphics core that AMD has built to date. This time around though, TSMC, AMD’s GPU foundry partner (for now) simply isn’t ready with their next-gen 28nm process, so Cayman, like Cypress, is built at 40nm. is to release a chip using a given process, revise that chip at some point during its life-cycle to enhance performance and/or power, and then release a totally new chip built using a more advanced process 12 – 16 months later. Cayman is the successor to the Cypress XT that was employed on the Radeon HD 5800 series, and while it does leverage many of the technologies from that generation, Cayman is a new chip that embraces a fresh core architecture designed to increase efficiency, performance and feature-set.Ĭayman does not, however, employ a new manufacturing process. That’s a freakin’ eternity in Internet time.Īs many of you may be aware, Cayman is the codename given to AMD’s newest flagship GPU, which will power the Radeon HD 6900 series (Antilles, aka the Radeon HD 6990, will uses a pair of Cayman GPUs when it arrives sometime next year). And why not? It has been almost 15 months since AMD launched the Radeon HD 5870, which remains the company’s fastest single-GPU.

In fact, back in October we were able to leak a tiny bit of official information in our coverage of the AMD Radeon HD 6800 series, but there’s been rampant discussion, spy images, and other leaks from all around the web for ages. We have been hearing rumblings about the products we’ll be showing you today, which are based on AMD’s next-gen “Cayman” GPU, for months now.
