GeForce GT 220 GDDR3 vs Nvidia Titan X

Intro

Compare those specifications to the Nvidia Titan X, which comes with GPU clock speed of 1417 MHz, and 12288 MB of GDDR5X RAM set to run at 1251 MHz through a 384-bit bus. It also is made up of 3584 SPUs, 224 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3		58 Watts
Nvidia Titan X		250 Watts
	Difference: 192 Watts (331%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X will be 1418% faster than the GeForce GT 220 GDDR3 in general, due to its higher data rate. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 459136 (1418%)

Texel Rate

The Nvidia Titan X will be quite a bit (about 3074%) better at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 307408 (3074%)

Pixel Rate

If using high levels of AA is important to you, then the Nvidia Titan X is the winner, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 131032 (2621%)

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 (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
