Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 650
IntroThe GeForce GTX 280 makes use of a 65 nm design. nVidia has set the core frequency at 602 MHz. The GDDR3 RAM runs at a frequency of 1107 MHz on this particular model. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.Compare those specifications to the GeForce GTX 650, which has core clock speeds of 1058 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 280 should in theory be much superior to the GeForce GTX 650 overall. (explain)
Texel RateThe GeForce GTX 280 will be quite a bit (more or less 42%) faster with regards to AF than the GeForce GTX 650. (explain)
Pixel RateThe GeForce GTX 280 is a small bit (more or less 14%) more effective at FSAA than the GeForce GTX 650, and will be able to handle higher resolutions without slowing down too much. (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

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
