GeForce GTX 260 vs Radeon R9 M375X

Intro

Compare those specs to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 260 should theoretically be quite a bit superior to the Radeon R9 M375X in general. (explain)

GeForce GTX 260		111888 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 39888 (55%)

Texel Rate

The Radeon R9 M375X should be just a bit (about 10%) faster with regards to anisotropic filtering than the GeForce GTX 260. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 3736 (10%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375X is the winner, not by a very large margin though. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GTX 260		16128 Mpixels/sec
	Difference: 112 (1%)

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 data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, 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 the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
