GeForce 8800 GTX vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which has GPU clock speed of 1015 MHz, and 4096 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 GTX, in theory, should be a bit faster than the Radeon R9 M375X in general. (explain)

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

Texel Rate

The Radeon R9 M375X is a little bit (about 10%) faster with regards to AF than the GeForce 8800 GTX. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375X is a better choice, but it probably won't make a huge difference. (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 maximum amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
