GeForce 8800 GTS (G92) vs Radeon R9 M270X

Intro

The GeForce 8800 GTS (G92) comes with a GPU core clock speed of 650 MHz, and the 512 MB of GDDR3 RAM runs at 970 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare all that to the Radeon R9 M270X, which features core clock speeds of 725 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M270X should be 16% faster than the GeForce 8800 GTS (G92) in general, because of its greater bandwidth. (explain)

Radeon R9 M270X 72000 MB/sec
GeForce 8800 GTS (G92) 62080 MB/sec
Difference: 9920 (16%)

Texel Rate

The GeForce 8800 GTS (G92) should be much (approximately 43%) faster with regards to anisotropic filtering than the Radeon R9 M270X. (explain)

GeForce 8800 GTS (G92) 41600 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 12600 (43%)

Pixel Rate

The Radeon R9 M270X is a little bit (more or less 12%) more effective at full screen anti-aliasing than the GeForce 8800 GTS (G92), and capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M270X 11600 Mpixels/sec
GeForce 8800 GTS (G92) 10400 Mpixels/sec
Difference: 1200 (12%)

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 maximum amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus 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 better the card's memory bandwidth, 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 amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
