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

Intro

The GeForce 8800 GTS (G80) 640MB uses a 90 nm design. nVidia has set the core frequency at 513 MHz. The GDDR3 memory runs at a speed of 792 MHz on this particular card. It features 96 SPUs along with 48 Texture Address Units and 20 Rasterization Operator Units.

Compare those specifications to the Radeon Vega Frontier Edition, which features clock speeds of 1382 MHz on the GPU, and 1890 MHz on the 16384 MB of HBM2 memory. It features 4096 SPUs along with 256 TAUs and 64 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, 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 number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
