Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce 9800 GTX+
IntroThe GeForce 9800 GT 512MB uses a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this model. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.Compare all that to the GeForce 9800 GTX+, which features GPU clock speed of 738 MHz, and 512 MB of GDDR3 memory set to run at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9800 GTX+, in theory, should be much faster than the GeForce 9800 GT 512MB in general. (explain)
Texel RateThe GeForce 9800 GTX+ is much (more or less 41%) better at texture filtering than the GeForce 9800 GT 512MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce 9800 GTX+ is the winner, by a large margin. (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 largest amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
