Compare any two graphics cards:
GeForce GT 230 vs Radeon HD 4670 1GB
IntroThe GeForce GT 230 comes with a GPU core speed of 550 MHz, and the 1536 MB of DDR3 RAM is set to run at 800 MHz through a 192-bit bus. It also is made up of 32 SPUs, 16 TAUs, and 8 ROPs.Compare all of that to the Radeon HD 4670 1GB, which comes with a core clock frequency of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory speed of 1100 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It is made up of 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GT 230 should perform just a bit faster than the Radeon HD 4670 1GB overall. (explain)
Texel RateThe Radeon HD 4670 1GB will be a lot (more or less 173%) better at AF than the GeForce GT 230. (explain)
Pixel RateThe Radeon HD 4670 1GB is much (about 36%) faster with regards to FSAA than the GeForce GT 230, and capable of handling 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 largest amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 filling the screen with pixels (the image). 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 maximum fill rate.
