Compare any two graphics cards:
GeForce GTX 465 vs Radeon HD 4870 2GB
IntroThe GeForce GTX 465 uses a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 memory works at a speed of 802 MHz on this card. It features 352 SPUs as well as 44 Texture Address Units and 32 ROPs.Compare those specs to the Radeon HD 4870 2GB, which has GPU core speed of 750 MHz, and 2048 MB of GDDR5 RAM set to run at 900 MHz through a 256-bit bus. It also features 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4870 2GB will be 12% faster than the GeForce GTX 465 overall, because of its greater data rate. (explain)
Texel RateThe Radeon HD 4870 2GB should be just a bit (about 12%) more effective at AF than the GeForce GTX 465. (explain)
Pixel RateThe GeForce GTX 465 should be a lot (about 62%) more effective at AA than the Radeon HD 4870 2GB, and also should be able to handle higher resolutions without losing too much performance. (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 megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock 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 processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
