Compare any two graphics cards:
GeForce GT 430 vs GeForce GTS 150
IntroThe GeForce GT 430 uses a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this model. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.Compare all of that to the GeForce GTS 150, which features a GPU core clock speed of 740 MHz, and 1024 MB of GDDR3 memory set to run at 500 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 150 should theoretically perform a small bit faster than the GeForce GT 430 in general. (explain)
Texel RateThe GeForce GTS 150 should be much (approximately 323%) more effective at texture filtering than the GeForce GT 430. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTS 150 is a better choice, 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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
