Radeon R7 M260X vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which makes use of a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory runs at a speed of 1650 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 470 should perform quite a bit faster than the Radeon R7 M260X overall. (explain)

Radeon RX 470		211200 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 147200 (230%)

Texel Rate

The Radeon RX 470 will be a lot (approximately 499%) more effective at texture filtering than the Radeon R7 M260X. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 98728 (499%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 470 is superior to the Radeon R7 M260X, by far. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 23032 (349%)

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 data (counted in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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