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

Intro

The GeForce 8800 GTS (G80) 320MB has a GPU clock speed of 513 MHz, and the 320 MB of GDDR3 RAM runs at 792 MHz through a 320-bit bus. It also is made up of 96 Stream Processors, 48 Texture Address Units, and 20 ROPs.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M365X will be 14% faster than the GeForce 8800 GTS (G80) 320MB overall, due to its higher bandwidth. (explain)

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

Texel Rate

The Radeon R9 M365X will be quite a bit (about 50%) better at texture filtering 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

The Radeon R9 M365X should be quite a bit (more or less 44%) more effective at AA than the GeForce 8800 GTS (G80) 320MB, and capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
