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

Intro

The GeForce 8800 GTS (G80) 640MB makes use of a 90 nm design. nVidia has clocked the core frequency at 513 MHz. The GDDR3 RAM is set to run at a frequency of 792 MHz on this particular card. It features 96 SPUs as well as 48 TAUs and 20 ROPs.

Compare those specifications to the Radeon R9 M365X, which comes with a core clock speed of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X should perform just a bit faster than the GeForce 8800 GTS (G80) 640MB overall. (explain)

Radeon R9 M365X 72000 MB/sec
GeForce 8800 GTS (G80) 640MB 63360 MB/sec
Difference: 8640 (14%)

Texel Rate

The Radeon R9 M365X is much (approximately 50%) more effective at anisotropic filtering 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

The Radeon R9 M365X should be quite a bit (more or less 44%) more effective at full screen anti-aliasing than the GeForce 8800 GTS (G80) 640MB, and also will be able to handle higher resolutions better. (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 information (measured in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
