Radeon R7 M260X vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which comes with a clock frequency of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon RX 460 should theoretically be a lot better than the Radeon R7 M260X in general. (explain)

Radeon RX 460		112000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 48000 (75%)

Texel Rate

The Radeon RX 460 is quite a bit (more or less 208%) more effective at anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 41240 (208%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 460 is a better choice, and very much so. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 10840 (164%)

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 information (counted in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at 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 video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
