GeForce GTX 970M vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which features GPU core speed of 800 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 970M will be 33% quicker than the Radeon R9 M370X overall, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTX 970M will be a lot (approximately 131%) better at anisotropic filtering 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 should be much (approximately 247%) better at anti-aliasing than the Radeon R9 M370X, and also will be able to handle higher resolutions better. (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: Bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
