GeForce GTX 460 SE vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which has a GPU core clock speed of 1015 MHz, and 4096 MB of DDR3 RAM set to run at 1100 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Radeon R9 M375		35200 MB/sec
	Difference: 73600 (209%)

Texel Rate

The Radeon R9 M375 will be a lot (about 30%) more effective 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

The GeForce GTX 460 SE is much (approximately 28%) better at FSAA than the Radeon R9 M375, and also should be able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the 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 graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
