Radeon R9 M295X vs Radeon RX 470

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470		120 Watts
Radeon R9 M295X		125 Watts
	Difference: 5 Watts (4%)

Memory Bandwidth

Performance-wise, the Radeon RX 470 should in theory be just a bit superior to the Radeon R9 M295X overall. (explain)

Radeon RX 470		211200 MB/sec
Radeon R9 M295X		176000 MB/sec
	Difference: 35200 (20%)

Texel Rate

The Radeon RX 470 will be quite a bit (more or less 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 running with lots of anti-aliasing is important to you, then the Radeon RX 470 is superior to the Radeon R9 M295X, by far. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
