Radeon R9 295X2 vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which has a core clock frequency of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 295X2 should be 789% faster than the Radeon R9 M365X in general, because of its higher data rate. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 568000 (789%)

Texel Rate

The Radeon R9 295X2 is quite a bit (more or less 868%) more effective at anisotropic filtering than the Radeon R9 M365X. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 321336 (868%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 295X2 is a better choice, by a large margin. (explain)

Radeon R9 295X2		130304 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 115504 (780%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be processed per second. This figure is worked out by multiplying the total amount 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video 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 colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
