GeForce GTX Titan vs Radeon R9 280X

Intro

Compare all of that to the Radeon R9 280X, which uses a 28 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 RAM runs at a speed of 1500 MHz on this model. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Radeon R9 280X		288000 MB/sec
	Difference: 384 (0%)

Texel Rate

The GeForce GTX Titan is a lot (about 72%) faster with regards to AF than the Radeon R9 280X. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R9 280X		108800 Mtexels/sec
	Difference: 78688 (72%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX Titan is a better choice, and very much so. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 12976 (48%)

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 maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
