GeForce GTX 970M vs Radeon R7 370 4G

Intro

Compare that to the Radeon R7 370 4G, which uses a 28 nm design. AMD has clocked the core speed at 975 MHz. The GDDR5 memory is set to run at a speed of 1400 MHz on this particular card. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

Theoretically speaking, the Radeon R7 370 4G should be 87% faster than the GeForce GTX 970M overall, due to its greater data rate. (explain)

Radeon R7 370 4G		179200 MB/sec
GeForce GTX 970M		96000 MB/sec
	Difference: 83200 (87%)

Texel Rate

The GeForce GTX 970M will be just a bit (about 18%) more effective at texture filtering than the Radeon R7 370 4G. (explain)

GeForce GTX 970M		73920 Mtexels/sec
Radeon R7 370 4G		62400 Mtexels/sec
	Difference: 11520 (18%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 970M is a better choice, by a large margin. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon R7 370 4G		31200 Mpixels/sec
	Difference: 13152 (42%)

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 across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the 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 the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
