GeForce GTX 295 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 speed at 1015 MHz. The GDDR5 memory works at a speed of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 295 should in theory be a lot superior to the Radeon R9 M375X in general. (explain)

GeForce GTX 295		223776 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 151776 (211%)

Texel Rate

The GeForce GTX 295 will be a lot (more or less 127%) better at AF than the Radeon R9 M375X. (explain)

GeForce GTX 295		92160 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 51560 (127%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 295 is superior to the Radeon R9 M375X, by far. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 16016 (99%)

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 megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
