Compare any two graphics cards:
GeForce 9800 GTX+ vs GeForce GTX 650
IntroThe GeForce 9800 GTX+ uses a 55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 memory works at a frequency of 1100 MHz on this specific card. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.Compare all that to the GeForce GTX 650, which has GPU core speed of 1058 MHz, and 1024 MB of GDDR5 memory running at 1250 MHz through a 128-bit bus. It also is comprised of 384 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 650 should in theory perform just a bit faster than the GeForce 9800 GTX+ overall. (explain)
Texel RateThe GeForce 9800 GTX+ is quite a bit (about 40%) faster with regards to texture filtering than the GeForce GTX 650. (explain)
Pixel RateThe GeForce GTX 650 should be a lot (more or less 43%) better at anti-aliasing than the GeForce 9800 GTX+, and should be capable of handling higher screen resolutions while still performing well. (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 max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR 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 number is calculated 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 in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
