GeForce GTX 260 vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which uses a 28 nm design. AMD has set the core speed at 1015 MHz. The DDR3 memory runs at a speed of 1100 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 should be 218% quicker than the Radeon R9 M375 overall, due to its higher data rate. (explain)

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

Texel Rate

The Radeon R9 M375 should be a small bit (more or less 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 a high screen resolution is important to you, then the Radeon R9 M375 is a better choice, 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: Bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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