Geforce GTX 760 vs Radeon R9 M290X

Intro

Compare all of that to the Radeon R9 M290X, which makes use of a 28 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory is set to run at a speed of 1200 MHz on this model. It features 1280 SPUs as well as 80 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M290X		100 Watts
Geforce GTX 760		170 Watts
	Difference: 70 Watts (70%)

Memory Bandwidth

In theory, the Geforce GTX 760 should perform quite a bit faster than the Radeon R9 M290X in general. (explain)

Geforce GTX 760		192256 MB/sec
Radeon R9 M290X		153600 MB/sec
	Difference: 38656 (25%)

Texel Rate

The Geforce GTX 760 should be a lot (approximately 38%) faster with regards to texture filtering than the Radeon R9 M290X. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon R9 M290X		68000 Mtexels/sec
	Difference: 26080 (38%)

Pixel Rate

If running with high levels of AA is important to you, then the Geforce GTX 760 is a better choice, not by a very large margin though. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon R9 M290X		27200 Mpixels/sec
	Difference: 4160 (15%)

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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
