Compare any two graphics cards:
GeForce GTS 150 vs Radeon HD 6870
IntroThe GeForce GTS 150 comes with a core clock frequency of 740 MHz and a GDDR3 memory frequency of 500 MHz. It also features a 256-bit bus, and uses a 55 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare those specifications to the Radeon HD 6870, which makes use of a 40 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 RAM is set to run at a speed of 1050 MHz on this specific model. It features 1120 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6870 should in theory be quite a bit better than the GeForce GTS 150 in general. (explain)
Texel RateThe Radeon HD 6870 will be a small bit (more or less 6%) more effective at anisotropic filtering than the GeForce GTS 150. (explain)
Pixel RateThe Radeon HD 6870 will be a lot (more or less 143%) more effective at FSAA than the GeForce GTS 150, and also able to handle higher screen 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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 are processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
