Radeon R7 M260X vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which comes with a core clock frequency of 1168 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 256-bit bus, and uses a 14 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 570 should be 258% faster than the Radeon R7 M260X overall, due to its greater data rate. (explain)

Radeon RX 570		229376 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 165376 (258%)

Texel Rate

The Radeon RX 570 is much (about 655%) better at AF than the Radeon R7 M260X. (explain)

Radeon RX 570		149504 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 129704 (655%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 570 is the winner, by a large margin. (explain)

Radeon RX 570		37376 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 30776 (466%)

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 largest amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels 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 the core 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
