GeForce GTX Titan Black vs Radeon R7 250X 2GB

Intro

Compare that to the Radeon R7 250X 2GB, which uses a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Radeon R7 250X 2GB		72000 MB/sec
	Difference: 264000 (367%)

Texel Rate

The GeForce GTX Titan Black will be a lot (more or less 433%) more effective at texture filtering than the Radeon R7 250X 2GB. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 173360 (433%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is a better choice, and very much so. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 26672 (167%)

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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
