GeForce GTX 460 SE vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which features a core clock frequency of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 SE should theoretically perform quite a bit faster than the Radeon R9 M375 overall. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 73600 (209%)

Texel Rate

The Radeon R9 M375 will be much (more or less 30%) better at AF than the GeForce GTX 460 SE. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 9400 (30%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 460 SE is a better choice, by a large margin. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 4560 (28%)

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 maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better 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 amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core 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 is also dependant 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.
