GeForce GTX 970M vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which uses a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 memory works at a speed of 1100 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 970M should perform much faster than the Radeon R9 M375 overall. (explain)

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

Texel Rate

The GeForce GTX 970M will be a lot (more or less 82%) more effective at anisotropic filtering than the Radeon R9 M375. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 970M is the winner, by far. (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 max amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could 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 ROPs 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
