Compare any two graphics cards:
GeForce GTX Titan Black vs Radeon HD 4870 1GB
IntroThe GeForce GTX Titan Black comes with core speeds of 889 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 RAM. It features 2880 SPUs as well as 240 TAUs and 48 Rasterization Operator Units.Compare all that to the Radeon HD 4870 1GB, which makes use of a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory runs at a speed of 900 MHz on this model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX Titan Black should theoretically perform much faster than the Radeon HD 4870 1GB in general. (explain)
Texel RateThe GeForce GTX Titan Black should be quite a bit (more or less 611%) faster with regards to anisotropic filtering than the Radeon HD 4870 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX Titan Black is superior to the Radeon HD 4870 1GB, by far. (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 information (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
