Geforce GTX 690 vs Radeon R9 M375X

Intro

Compare those specs to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this specific card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Geforce GTX 690, in theory, should perform quite a bit faster than the Radeon R9 M375X overall. (explain)

Geforce GTX 690		384512 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 312512 (434%)

Texel Rate

The Geforce GTX 690 should be quite a bit (about 477%) better at anisotropic filtering than the Radeon R9 M375X. (explain)

Geforce GTX 690		234240 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 193640 (477%)

Pixel Rate

The Geforce GTX 690 should be much (about 261%) better at anti-aliasing than the Radeon R9 M375X, and will be able to handle higher screen resolutions better. (explain)

Geforce GTX 690		58560 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 42320 (261%)

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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
