GeForce GTX 960 vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which features core clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

	Difference: 31528 (78%)

Pixel Rate

The GeForce GTX 960 should be quite a bit (about 122%) faster with regards to FSAA than the Radeon R9 M375, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 960		36064 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 19824 (122%)

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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at 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 write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
