Compare any two graphics cards:
GeForce 9800 GTX+ vs GeForce GTX 650 Ti
IntroThe GeForce 9800 GTX+ features a clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also makes use of a 256-bit bus, and uses a 55 nm design. It features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specs to the GeForce GTX 650 Ti, which has GPU core speed of 928 MHz, and 1024 MB of GDDR5 RAM set to run at 1350 MHz through a 128-bit bus. It also is made up of 768 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 650 Ti should in theory be much superior to the GeForce 9800 GTX+ overall. (explain)
Texel RateThe GeForce GTX 650 Ti is a lot (about 26%) better at texture filtering than the GeForce 9800 GTX+. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 650 Ti is a better choice, by far. (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 information (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
