GeForce GT 220 GDDR3 vs Geforce GTX 760

Intro

Compare those specs to the Geforce GTX 760, which has a core clock frequency of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is made up of 1152 SPUs, 96 Texture Address Units, and 32 ROPs.

Texel Rate

The Geforce GTX 760 is quite a bit (approximately 841%) better at AF than the GeForce GT 220 GDDR3. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 84080 (841%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 760 is superior to the GeForce GT 220 GDDR3, and very much so. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 26360 (527%)

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 information (counted in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
