GeForce GT 450 (OEM) vs Radeon R7 260X

Intro

Compare all that to the Radeon R7 260X, which uses a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 memory is set to run at a speed of 1625 MHz on this card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 8000 (8%)

Texel Rate

The Radeon R7 260X will be much (more or less 225%) more effective at AF than the GeForce GT 450 (OEM). (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 42640 (225%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 450 (OEM) is superior to the Radeon R7 260X, though not by far. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 1360 (8%)

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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
