GeForce GTX 650 vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 650 is 11% quicker than the Radeon R9 M375X in general, due to its higher bandwidth. (explain)

GeForce GTX 650		80000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 8000 (11%)

Texel Rate

The Radeon R9 M375X will be a small bit (about 20%) better at AF than the GeForce GTX 650. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 6744 (20%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 650 is superior to the Radeon R9 M375X, though only just barely. (explain)

GeForce GTX 650		16928 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 688 (4%)

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 maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
