GeForce GTX 650 vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 memory works at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 should be a small bit faster than the Radeon R9 M375X in general. (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 bit (about 20%) more effective at texture filtering than the GeForce GTX 650. (explain)

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

Pixel Rate

The GeForce GTX 650 will be a little bit (about 4%) better at FSAA than the Radeon R9 M375X, and also should be capable of handling higher screen resolutions better. (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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 can be processed in one second. This is worked out 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
