Nvidia Titan Xp vs Radeon R5 M255

Intro

Compare all that to the Radeon R5 M255, which makes use of a 28 nm design. AMD has set the core frequency at 940 MHz. The DDR3 memory works at a frequency of 1000 MHz on this card. It features 320 SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Nvidia Titan Xp should perform quite a bit faster than the Radeon R5 M255 overall. (explain)

Nvidia Titan Xp		560845 MB/sec
Radeon R5 M255		16000 MB/sec
	Difference: 544845 (3405%)

Texel Rate

The Nvidia Titan Xp should be a lot (approximately 1920%) better at anisotropic filtering than the Radeon R5 M255. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
Radeon R5 M255		18800 Mtexels/sec
	Difference: 360880 (1920%)

Pixel Rate

If using a high resolution is important to you, then the Nvidia Titan Xp is the winner, by far. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
Radeon R5 M255		7520 Mpixels/sec
	Difference: 144352 (1920%)

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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out 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 bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could 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 the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
