GeForce GTX 260 vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which comes with core clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 should be quite a bit faster than the Radeon R9 M375 in general. (explain)

GeForce GTX 260		111888 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 76688 (218%)

Texel Rate

The Radeon R9 M375 is just a bit (approximately 10%) more effective at AF than the GeForce GTX 260. (explain)

Radeon R9 M375		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 M375 is the winner, but only just. (explain)

Radeon R9 M375		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 information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
