GeForce 8800 GTS (G80) 640MB vs Radeon R9 M365X

Intro

The GeForce 8800 GTS (G80) 640MB has a clock speed of 513 MHz and a GDDR3 memory frequency of 792 MHz. It also makes use of a 320-bit memory bus, and uses a 90 nm design. It is comprised of 96 SPUs, 48 Texture Address Units, and 20 Raster Operation Units.

Compare those specifications to the Radeon R9 M365X, which comes with GPU clock speed of 925 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 ROPs.

GeForce 8800 GTS (G80) 640MB 63360 MB/sec
Difference: 8640 (14%)

Texel Rate

The Radeon R9 M365X is much (approximately 50%) more effective at AF than the GeForce 8800 GTS (G80) 640MB. (explain)

Radeon R9 M365X 37000 Mtexels/sec
GeForce 8800 GTS (G80) 640MB 24624 Mtexels/sec
Difference: 12376 (50%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M365X is the winner, by far. (explain)

Radeon R9 M365X 14800 Mpixels/sec
GeForce 8800 GTS (G80) 640MB 10260 Mpixels/sec
Difference: 4540 (44%)

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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core 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 also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
