Compare any two graphics cards:
GeForce GT 230 vs GeForce GTX 465
IntroThe GeForce GT 230 makes use of a 40 nm design. nVidia has set the core frequency at 550 MHz. The DDR3 RAM runs at a frequency of 800 MHz on this specific card. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specifications to the GeForce GTX 465, which makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory runs at a speed of 802 MHz on this particular model. It features 352 SPUs along with 44 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 465 will be 167% faster than the GeForce GT 230 in general, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 465 should be quite a bit (about 204%) better at anisotropic filtering than the GeForce GT 230. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 465 is a better choice, 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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
