GeForce GTX 970M vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 970M should perform quite a bit faster than the Radeon R9 M370X overall. (explain)

GeForce GTX 970M		96000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 24000 (33%)

Texel Rate

The GeForce GTX 970M should be a lot (more or less 131%) faster with regards to AF than the Radeon R9 M370X. (explain)

GeForce GTX 970M		73920 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 41920 (131%)

Pixel Rate

The GeForce GTX 970M is much (more or less 247%) faster with regards to AA than the Radeon R9 M370X, and also should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 31552 (247%)

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 max amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be processed per second. This number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
