GeForce GTX 560 Ti 448 vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which has a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti 448 should perform quite a bit faster than the Radeon R9 M375X overall. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 72000 (100%)

Texel Rate

The GeForce GTX 560 Ti 448 is a little bit (more or less 1%) more effective at AF than the Radeon R9 M375X. (explain)

GeForce GTX 560 Ti 448		40992 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 392 (1%)

Pixel Rate

The GeForce GTX 560 Ti 448 should be a lot (approximately 80%) better at FSAA than the Radeon R9 M375X, and also able to handle higher resolutions while still performing well. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 13040 (80%)

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 largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a 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 - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
