GeForce 8800 GTS (G92) vs Radeon R9 M270X

Intro

The GeForce 8800 GTS (G92) features a core clock speed of 650 MHz and a GDDR3 memory frequency of 970 MHz. It also features a 256-bit bus, and uses a 65 nm design. It features 128 SPUs, 64 TAUs, and 16 ROPs.

Compare all that to the Radeon R9 M270X, which features GPU core speed of 725 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M270X should perform a little bit faster than the GeForce 8800 GTS (G92) in general. (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 quite a bit (more or less 43%) faster with regards to texture 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

If running with lots of anti-aliasing is important to you, then the Radeon R9 M270X is the winner, though not by far. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
