Radeon R9 M295X vs Radeon RX 470

Intro

Compare those specs to the Radeon RX 470, which has GPU core speed of 926 MHz, and 8192 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Radeon R9 M295X		176000 MB/sec
	Difference: 35200 (20%)

Texel Rate

The Radeon RX 470 is quite a bit (about 23%) better at AF than the Radeon R9 M295X. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon R9 M295X		96000 Mtexels/sec
	Difference: 22528 (23%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 470 is superior to the Radeon R9 M295X, and very much so. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 5632 (23%)

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 data (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, 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 maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
