Compare any two graphics cards:
GeForce GT 340 vs GeForce GTS 450
IntroThe GeForce GT 340 makes use of a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 memory runs at a frequency of 850 MHz on this particular model. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.Compare those specs to the GeForce GTS 450, which has a core clock frequency of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 192 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTS 450 should in theory be a little bit better than the GeForce GT 340 in general. (explain)
Texel RateThe GeForce GTS 450 is much (approximately 42%) more effective at texture filtering than the GeForce GT 340. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTS 450 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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, 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 anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core 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 of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
