GeForce 8800 GTS (G80) 640MB vs Radeon R9 M370X

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 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M370X, which comes with core speeds of 800 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M370X should in theory be a little bit superior to the GeForce 8800 GTS (G80) 640MB overall. (explain)

Radeon R9 M370X 72000 MB/sec
GeForce 8800 GTS (G80) 640MB 63360 MB/sec
Difference: 8640 (14%)

Texel Rate

The Radeon R9 M370X is much (about 30%) faster with regards to texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)

Radeon R9 M370X 32000 Mtexels/sec
GeForce 8800 GTS (G80) 640MB 24624 Mtexels/sec
Difference: 7376 (30%)

Pixel Rate

The Radeon R9 M370X should be quite a bit (approximately 25%) better at AA than the GeForce 8800 GTS (G80) 640MB, and also should be capable of handling higher resolutions better. (explain)

Radeon R9 M370X 12800 Mpixels/sec
GeForce 8800 GTS (G80) 640MB 10260 Mpixels/sec
Difference: 2540 (25%)

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 (in units of MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 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 reach the max fill rate.
