Compare any two graphics cards:
GeForce GT 220 GDDR3 vs GeForce GT 420
IntroThe GeForce GT 220 GDDR3 comes with core clock speeds of 625 MHz on the GPU, and 1012 MHz on the 512 MB of GDDR3 RAM. It features 48 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare all of that to the GeForce GT 420, which features a clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 48 SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 220 GDDR3 should in theory perform a bit faster than the GeForce GT 420 overall. (explain)
Texel RateThe GeForce GT 220 GDDR3 will be a lot (approximately 79%) better at texture filtering than the GeForce GT 420. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GT 220 GDDR3 is superior to the GeForce GT 420, by far. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 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 are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
