GeForce 8800 GTX vs Radeon R9 M270X

Intro

Compare those specifications to the Radeon R9 M270X, which uses a 28 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 8800 GTX should be a little bit faster than the Radeon R9 M270X in general. (explain)

GeForce 8800 GTX		86400 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce 8800 GTX will be much (approximately 27%) more effective at AF than the Radeon R9 M270X. (explain)

GeForce 8800 GTX		36800 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 7800 (27%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 8800 GTX is the winner, but it probably won't make a huge difference. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 2200 (19%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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