Radeon R7 370 2G vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which has a clock speed of 1175 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Texel Rate

The Radeon RX 560 is much (more or less 21%) better at texture filtering than the Radeon R7 370 2G. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R7 370 2G		62400 Mtexels/sec
	Difference: 12800 (21%)

Pixel Rate

The Radeon R7 370 2G is a lot (more or less 66%) more effective at full screen anti-aliasing than the Radeon RX 560, and also will be capable of handling higher screen resolutions better. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 12400 (66%)

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 (in units of MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 can be applied in one second. This is calculated by multiplying the total texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
