Nvidia Titan X vs Radeon R7 250

Intro

Compare all of that to the Radeon R7 250, which has clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250		65 Watts
Nvidia Titan X		250 Watts
	Difference: 185 Watts (285%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X should perform quite a bit faster than the Radeon R7 250 overall. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R7 250		73600 MB/sec
	Difference: 417920 (568%)

Texel Rate

The Nvidia Titan X is a lot (about 1223%) faster with regards to AF than the Radeon R7 250. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 293408 (1223%)

Pixel Rate

If running with a high screen resolution is important to you, then the Nvidia Titan X is the winner, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 128032 (1600%)

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 (in units of MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number 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 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 that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the maximum fill rate.
