GeForce GT 450 (OEM) vs Radeon R7 260X

Intro

Compare all of that to the Radeon R7 260X, which comes with core speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Texel Rate

The Radeon R7 260X is a lot (about 225%) more effective at anisotropic filtering 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 lots of anti-aliasing is important to you, then the GeForce GT 450 (OEM) is a better choice, 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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported over 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 RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
