Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce GT 440 1.5GB
IntroThe GeForce 9500 GT 512MB GDDR3 features a core clock frequency of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specifications to the GeForce GT 440 1.5GB, which makes use of a 40 nm design. nVidia has set the core speed at 594 MHz. The GDDR3 memory runs at a speed of 900 MHz on this particular card. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 440 1.5GB should in theory be quite a bit faster than the GeForce 9500 GT 512MB GDDR3 overall. (explain)
Texel RateThe GeForce GT 440 1.5GB is a lot (more or less 62%) faster with regards to anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GT 440 1.5GB is the winner, by a large margin. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units 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 in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
