Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs GeForce GT 420
IntroThe GeForce 9500 GT 1GB GDDR3 uses a 55 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 RAM runs at a speed of 800 MHz on this specific card. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the GeForce GT 420, which features GPU clock speed of 700 MHz, and 2048 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also features 48 SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthTheoretically speaking, the GeForce GT 420 should be 13% faster than the GeForce 9500 GT 1GB GDDR3 overall, because of its higher data rate. (explain)
Texel RateThe GeForce 9500 GT 1GB GDDR3 is much (more or less 57%) more effective at texture filtering than the GeForce GT 420. (explain)
Pixel RateThe GeForce 9500 GT 1GB GDDR3 should be much (approximately 57%) faster with regards to AA than the GeForce GT 420, and will be able to handle higher resolutions more effectively. (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 largest amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 memory bandwidth is, the lower the ability to reach the max fill rate.
