Radeon R7 M260 vs Radeon RX 470 4GB

Intro

Compare all of that to the Radeon RX 470 4GB, which makes use of a 14 nm design. AMD has set the core frequency at 926 MHz. The GDDR5 RAM works at a frequency of 1650 MHz on this specific card. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 470 4GB will be 1220% faster than the Radeon R7 M260 overall, because of its higher bandwidth. (explain)

Radeon RX 470 4GB		211200 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 195200 (1220%)

Texel Rate

The Radeon RX 470 4GB is much (more or less 591%) better at texture filtering than the Radeon R7 M260. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 101368 (591%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 470 4GB is a better choice, by a large margin. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 23912 (418%)

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 maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
