GeForce GTX 970M vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which comes with core speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 970M is 33% quicker than the Radeon R9 M365X in general, due to its higher bandwidth. (explain)

GeForce GTX 970M		96000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 24000 (33%)

Texel Rate

The GeForce GTX 970M should be a lot (about 100%) better at texture filtering than the Radeon R9 M365X. (explain)

GeForce GTX 970M		73920 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 36920 (100%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 970M is a better choice, by far. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 29552 (200%)

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 information (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
