GeForce 8800 GTX vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which features a core clock frequency of 1015 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 8800 GTX should in theory be a small 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 will be a bit (approximately 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 resolution is important to you, then the Radeon R9 M375X is a better choice, though only just barely. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core 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 most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
