The UVD engine has been tuned to offer better performance while reducing number of transistors. This may be noticed in a small improvement to performance when enabling anti-aliasing. The render back-ends have been tweaked to improve efficiency. Geometry shader performance has been optimized to perform better in more types of geometry shader operations. Better arbitration in the memory controller when different parts of the chips make requests. Cache efficiency improved, particularly when making lots of small requests. Improved “PowerPlay” power-saving features reduces power consumption when idle and especially during “light usage” scenarios like when rendering Vista’s 3D desktop. The new chips supports DirectX 10.1, including Shader Model 4.1, mandatory FP32 filtering, mandatory 4x multisample AA with samples exposed to shaders, index-able cube maps, etc. #Nvidia geforce 8800 gt vs ati radeon hd 2600 xt full#
It handles full entropy decode of both H.264 and VC-1.

RV670 incorporates the UVD video decoder found in Radeon HD 24 cards, but not in the 2900 Pro and XT. Though it appears at first glance to be an R600 with half the memory interface, the RV670 chip has incorporated several enhancements: It’s a more suitable number for this chip, with about half the bandwidth, though. We always thought that 16 texture units and 16 render back-ends was a bit on the low side for the 2900 XT, and prevented it from really making the most out of all that bandwidth. Still, it retains all 320 scalar stream processors, 16 render back-ends, and 16 texture units. The clock speed is 10% lower, and it’s got a 256-bit memory interface instead of a 512-bit one. It’s equivalent to a “Pro” model in the old scheme, while the 3870 is equivalent to the former “XT.” Nvidia, please steal this idea.īefore we get into the specific differences between this RV670 and the R600, let’s look at some relevant speeds and feeds:Īt first glance, it looks like this new $180 card might come within spitting distance of the $400 Radeon HD 2900 XT. So the Radeon HD 3850 is the third GPU generation, 8-series, 50-variant. The first denotes the GPU generation, the second the card family, and the last two the particular variant. From now until the foreseeable future, the plan is to have all cards branded with a just a four-digit number. First, a note on naming conventions.ĪMD is thankfully getting rid of all this “XT” and “Pro” and “GT” business in their naming conventions. RV670 brings with it several enhancements to the R600 core, which we’ll detail in a moment. #Nvidia geforce 8800 gt vs ati radeon hd 2600 xt series#
Suffice it to say you should read that article if you need a refresher on AMD/ATI’s 6xx series DX10 graphics architecture. The base architecture is the same, and we won’t dive into all that right now because we wrote exhaustively about it earlier this year. The RV670 chip powering the Radeon HD 38 cards is not identical to the R600 found in the Radeon HD 2900 XT, only at 55nm.
