GeForce 8800 GTX vs Radeon R9 M375X

Intro

The GeForce 8800 GTX features a core clock frequency of 575 MHz and a GDDR3 memory speed of 900 MHz. It also features a 384-bit memory bus, and uses a 90 nm design. It is made up of 128 SPUs, 64 TAUs, and 24 Raster Operation Units.

Compare those specifications to the Radeon R9 M375X, which has a core clock frequency of 1015 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 8800 GTX should theoretically be a little bit superior to the Radeon R9 M375X overall. (explain)

GeForce 8800 GTX 86400 MB/sec
Radeon R9 M375X 72000 MB/sec
Difference: 14400 (20%)

Texel Rate

The Radeon R9 M375X should be just a bit (more or less 10%) faster with regards to texture filtering than the GeForce 8800 GTX. (explain)

Radeon R9 M375X 40600 Mtexels/sec
GeForce 8800 GTX 36800 Mtexels/sec
Difference: 3800 (10%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M375X is a better choice, but only just. (explain)

Radeon R9 M375X 16240 Mpixels/sec
GeForce 8800 GTX 13800 Mpixels/sec
Difference: 2440 (18%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
