GeForce 8800 GTX vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which has core clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 8800 GTX should be a bit faster than the Radeon R9 M365X in general. (explain)

GeForce 8800 GTX		86400 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The Radeon R9 M365X should be just a bit (approximately 1%) more effective at anisotropic filtering than the GeForce 8800 GTX. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 200 (1%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M365X is a better choice, but it probably won't make a huge difference. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 1000 (7%)

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 largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 are applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
