GeForce GTX 970M vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which comes with a core clock frequency of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 970M should be 173% quicker than the Radeon R9 M375 in general, due to its greater bandwidth. (explain)

GeForce GTX 970M		96000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 60800 (173%)

Texel Rate

The GeForce GTX 970M should be much (approximately 82%) better at AF than the Radeon R9 M375. (explain)

GeForce GTX 970M		73920 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 33320 (82%)

Pixel Rate

The GeForce GTX 970M is quite a bit (more or less 173%) more effective at AA than the Radeon R9 M375, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 28112 (173%)

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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
