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 speed at 513 MHz. The GDDR3 memory runs at a speed of 792 MHz on this specific card. It features 96 SPUs as well as 48 Texture Address Units and 20 ROPs.

Compare all of that to the Radeon Vega Frontier Edition, which has GPU core speed of 1382 MHz, and 16384 MB of HBM2 RAM running at 1890 MHz through a 2048-bit bus. It also features 4096 Stream Processors, 256 TAUs, and 64 Raster Operation Units.

GeForce 8800 GTS (G80) 640MB 143 Watts
Radeon Vega Frontier Edition 300 Watts
Difference: 157 Watts (110%)

Memory Bandwidth

Theoretically speaking, the Radeon Vega Frontier Edition should be 682% faster than the GeForce 8800 GTS (G80) 640MB in general, due to its greater data rate. (explain)

Radeon Vega Frontier Edition 495452 MB/sec
GeForce 8800 GTS (G80) 640MB 63360 MB/sec
Difference: 432092 (682%)

Texel Rate

The Radeon Vega Frontier Edition is quite a bit (about 1337%) more effective at AF than the GeForce 8800 GTS (G80) 640MB. (explain)

Radeon Vega Frontier Edition 353792 Mtexels/sec
GeForce 8800 GTS (G80) 640MB 24624 Mtexels/sec
Difference: 329168 (1337%)

Pixel Rate

The Radeon Vega Frontier Edition should be much (more or less 762%) more effective at anti-aliasing than the GeForce 8800 GTS (G80) 640MB, and will be able to handle higher resolutions while still performing well. (explain)

Radeon Vega Frontier Edition 88448 Mpixels/sec
GeForce 8800 GTS (G80) 640MB 10260 Mpixels/sec
Difference: 78188 (762%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
