Radeon R7 M260X vs Radeon RX 470

Intro

Compare all that to the Radeon RX 470, which has a GPU core clock speed of 926 MHz, and 8192 MB of GDDR5 memory running at 1650 MHz through a 256-bit bus. It also features 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 470 should theoretically be quite a bit better 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 quite a bit (approximately 499%) more effective at AF than the Radeon R7 M260X. (explain)

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

Pixel Rate

The Radeon RX 470 should be a lot (about 349%) faster with regards to AA than the Radeon R7 M260X, and also able to handle higher resolutions without losing too much performance. (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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This number 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 that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on 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 potential to get to the max fill rate.
