Geforce GTX 760 vs Radeon R9 M295X

Intro

Compare those specifications to the Radeon R9 M295X, which uses a 28 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory is set to run at a frequency of 1375 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Geforce GTX 760		94080 Mtexels/sec
	Difference: 1920 (2%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 760 is superior to the Radeon R9 M295X, and very much so. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 7360 (31%)

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: Bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 memory bandwidth is, the lower the ability to get to the max fill rate.
