GeForce GTX 650 Ti 2GB vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which has core clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650 Ti 2GB should in theory be much faster than the Radeon R9 M375 in general. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 51200 (145%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be a lot (about 46%) more effective at texture filtering than the Radeon R9 M375. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 18792 (46%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375 is a better choice, though not by far. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 1392 (9%)

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 largest amount of information (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, 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 record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
