GeForce GT 220 GDDR3 vs Radeon R7 260X

Intro

Compare all that to the Radeon R7 260X, which comes with GPU core speed of 1100 MHz, and 2048 MB of GDDR5 memory running at 1625 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.

GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 71616 (221%)

Texel Rate

The Radeon R7 260X should be much (more or less 516%) faster with regards to texture filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 51600 (516%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 260X is superior to the GeForce GT 220 GDDR3, by a large margin. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 12600 (252%)

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 maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at 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 card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
