Nvidia Titan Xp vs Radeon R7 250X 2GB

Intro

Compare those specifications to the Radeon R7 250X 2GB, which features GPU clock speed of 1000 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X 2GB		95 Watts
Nvidia Titan Xp		250 Watts
	Difference: 155 Watts (163%)

Memory Bandwidth

In theory, the Nvidia Titan Xp should be quite a bit faster than the Radeon R7 250X 2GB in general. (explain)

Nvidia Titan Xp		560845 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 488845 (679%)

Texel Rate

The Nvidia Titan Xp should be a lot (approximately 849%) more effective at AF than the Radeon R7 250X 2GB. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 339680 (849%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Nvidia Titan Xp is the winner, by a large margin. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 135872 (849%)

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 data (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
