Compare any two graphics cards:
GeForce GT 220 GDDR3 vs GeForce GT 450 (OEM)
IntroThe GeForce GT 220 GDDR3 makes use of a 40 nm design. nVidia has clocked the core speed at 625 MHz. The GDDR3 RAM is set to run at a speed of 1012 MHz on this particular model. It features 48 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the GeForce GT 450 (OEM), which has core speeds of 790 MHz on the GPU, and 1000 MHz on the 1536 MB of GDDR5 RAM. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GT 450 (OEM) should perform much faster than the GeForce GT 220 GDDR3 in general. (explain)
Texel RateThe GeForce GT 450 (OEM) should be much (about 90%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateThe GeForce GT 450 (OEM) will be quite a bit (more or less 279%) more effective at anti-aliasing than the GeForce GT 220 GDDR3, and will be able to handle higher screen resolutions better. (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 max amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, 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 is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
