GeForce GTX 650 vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which comes with GPU clock speed of 1015 MHz, and 4096 MB of DDR3 memory set to run at 1100 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650 should in theory perform a lot faster than the Radeon R9 M375 overall. (explain)

GeForce GTX 650		80000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 44800 (127%)

Texel Rate

The Radeon R9 M375 is a little bit (more or less 20%) faster with regards to texture filtering than the GeForce GTX 650. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 6744 (20%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 650 is superior to the Radeon R9 M375, but it probably won't make a huge difference. (explain)

GeForce GTX 650		16928 Mpixels/sec
Radeon R9 M375		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 data (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
