Compare any two graphics cards:
GeForce GTS 150 vs GeForce GTX 590
IntroThe GeForce GTS 150 uses a 55 nm design. nVidia has set the core speed at 740 MHz. The GDDR3 memory works at a frequency of 500 MHz on this specific card. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the GeForce GTX 590, which uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory runs at a frequency of 855 MHz on this model. It features 512 SPUs as well as 64 Texture Address Units and 48 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 590 should perform a lot faster than the GeForce GTS 150 overall. (explain)
Texel RateThe GeForce GTX 590 is quite a bit (approximately 64%) better at texture filtering than the GeForce GTS 150. (explain)
Pixel RateThe GeForce GTX 590 should be much (more or less 392%) more effective at FSAA than the GeForce GTS 150, and also 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of 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 anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
