GeForce GTX 260 vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 RAM runs at a speed of 1100 MHz on this specific card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 260 should in theory be much better 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 a little 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

The Radeon R9 M375 is just a bit (about 1%) better at full screen anti-aliasing than the GeForce GTX 260, and able to handle higher screen resolutions without slowing down too much. (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 (measured in MB per second) that can be transferred across the external memory interface in a 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 bandwidth is, 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
