GeForce 8800 GTS (G80) 320MB vs Radeon R9 M365X

Intro

The GeForce 8800 GTS (G80) 320MB has a GPU core clock speed of 513 MHz, and the 320 MB of GDDR3 RAM is set to run at 792 MHz through a 320-bit bus. It also is made up of 96 SPUs, 48 TAUs, and 20 Raster Operation Units.

Compare all of that to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X should in theory perform a little bit faster than the GeForce 8800 GTS (G80) 320MB in general. (explain)

Radeon R9 M365X 72000 MB/sec
GeForce 8800 GTS (G80) 320MB 63360 MB/sec
Difference: 8640 (14%)

Texel Rate

The Radeon R9 M365X is a lot (about 50%) more effective at AF than the GeForce 8800 GTS (G80) 320MB. (explain)

Radeon R9 M365X 37000 Mtexels/sec
GeForce 8800 GTS (G80) 320MB 24624 Mtexels/sec
Difference: 12376 (50%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M365X is the winner, by a large margin. (explain)

Radeon R9 M365X 14800 Mpixels/sec
GeForce 8800 GTS (G80) 320MB 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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
