Compare any two graphics cards:
GeForce 9800 GTX vs GeForce 9800 GTX+
IntroThe GeForce 9800 GTX has a core clock speed of 675 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit bus, and makes use of a 65 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare all that to the GeForce 9800 GTX+, which features a clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same bandwidth, so theoretically they should perform exactly the same. (explain)
Texel RateThe GeForce 9800 GTX+ should be a small bit (approximately 9%) faster with regards to AF than the GeForce 9800 GTX. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce 9800 GTX+ is a better choice, but it probably won't make a huge difference. (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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
