Geforce GTX 690 vs Radeon R9 M375

Intro

Compare all that to the Radeon R9 M375, which features 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 Stream Processors, 40 TAUs, 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 M375 in general. (explain)

Geforce GTX 690		384512 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 349312 (992%)

Texel Rate

The Geforce GTX 690 should be quite a bit (about 477%) better at texture filtering than the Radeon R9 M375. (explain)

Geforce GTX 690		234240 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 193640 (477%)

Pixel Rate

The Geforce GTX 690 should be quite a bit (more or less 261%) more effective at anti-aliasing than the Radeon R9 M375, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Geforce GTX 690		58560 Mpixels/sec
Radeon R9 M375		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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
