GeForce GT 220 GDDR3 vs GeForce GTX Titan

Intro

Compare all of that to the GeForce GTX Titan, which uses a 28 nm design. nVidia has set the core frequency at 837 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this specific model. It features 2688 SPUs along with 224 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically, the GeForce GTX Titan should perform quite a bit faster than the GeForce GT 220 GDDR3 in general. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 256000 (791%)

Texel Rate

The GeForce GTX Titan will be a lot (approximately 1775%) more effective at texture filtering than the GeForce GT 220 GDDR3. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 177488 (1775%)

Pixel Rate

The GeForce GTX Titan should be much (approximately 704%) better at anti-aliasing than the GeForce GT 220 GDDR3, and also capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 35176 (704%)

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 information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
