GeForce GTX 260 216SP 55 nm 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 speed at 1015 MHz. The DDR3 memory is set to run at a frequency of 1100 MHz on this particular card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 260 216SP 55 nm should in theory perform a lot faster than the Radeon R9 M375 overall. (explain)

GeForce GTX 260 216SP 55 nm		111888 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 76688 (218%)

Texel Rate

The GeForce GTX 260 216SP 55 nm will be a little bit (more or less 2%) more effective at texture filtering than the Radeon R9 M375. (explain)

GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 872 (2%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375 is a better choice, but not by far. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GTX 260 216SP 55 nm		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 (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, 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 number of pixels that 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 Raster Operations Pipelines by the the core speed of the card. 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 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 reach the max fill rate.
