GeForce 8800 GTS (G80) 640MB vs Radeon Vega Frontier Edition

Intro

The GeForce 8800 GTS (G80) 640MB features core clock speeds of 513 MHz on the GPU, and 792 MHz on the 640 MB of GDDR3 RAM. It features 96 SPUs as well as 48 Texture Address Units and 20 Rasterization Operator Units.

Compare those specifications to the Radeon Vega Frontier Edition, which features a clock speed of 1382 MHz and a HBM2 memory frequency of 1890 MHz. It also uses a 2048-bit memory bus, and makes use of a 14 nm design. It is comprised of 4096 SPUs, 256 TAUs, and 64 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
