Radeon R9 M295X vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which comes with GPU clock speed of 926 MHz, and 8192 MB of GDDR5 memory running at 1650 MHz through a 256-bit bus. It also features 2048 Stream Processors, 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

As far as performance goes, the Radeon RX 470 should in theory be just a bit better than 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 a lot (more or less 23%) faster with regards to 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 a high resolution 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 maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum 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 better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. 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 output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
