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.

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.
OpenCL 1.1 (1.0) Vulkan N/A CUDA 1.0 Shader Model 4.0 Card Notes 518.4 GFLOPs when Multiply Operation is available. The card measures 270 mm in length, and features a dual-slot cooling solution. GeForce 8800 GTX is connected to the rest of the system using a PCI-Express 1.0 x16 interface. Display outputs include: 2x DVI, 1x S-Video. The GPU is operating at a frequency of 576 MHz, memory is running at 900 MHz.īeing a dual-slot card, the NVIDIA GeForce 8800 GTX draws power from 2x 6-pin power connectors, with power draw rated at 155 W maximum. NVIDIA has paired 768 MB GDDR3 memory with the GeForce 8800 GTX, which are connected using a 384-bit memory interface. It features 128 shading units, 32 texture mapping units, and 24 ROPs. The G80 graphics processor is a large chip with a die area of 484 mm² and 681 million transistors. Even though it supports DirectX 11, the feature level is only 10_0, which can be problematic with many DirectX 11 & DirectX 12 titles. Built on the 90 nm process, and based on the G80 graphics processor, in its G80-300-A2 variant, the card supports DirectX 11.1. The GeForce 8800 GTX was a high-end graphics card by NVIDIA, launched on November 8th, 2006.
