GeForce GTX 590 vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which features a clock frequency of 1015 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Radeon R9 M375X		72000 MB/sec
	Difference: 256320 (356%)

Texel Rate

The GeForce GTX 590 will be quite a bit (approximately 91%) better at AF than the Radeon R9 M375X. (explain)

GeForce GTX 590		77696 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 37096 (91%)

Pixel Rate

The GeForce GTX 590 should be much (approximately 259%) more effective at full screen anti-aliasing than the Radeon R9 M375X, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 590		58272 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 42032 (259%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
