Compare any two graphics cards:
GeForce GT 230 vs Radeon HD 4670 1GB
IntroThe GeForce GT 230 comes with a core clock frequency of 550 MHz and a DDR3 memory frequency of 800 MHz. It also features a 192-bit memory bus, and uses a 40 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 4670 1GB, which has GPU core speed of 750 MHz, and 1024 MB of GDDR4/GDDR3/DDR3/DDR2 RAM set to run at 1100 MHz through a 128-bit bus. It also is comprised of 320(64x5) SPUs, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 230 should be a bit faster than the Radeon HD 4670 1GB in general. (explain)
Texel RateThe Radeon HD 4670 1GB is quite a bit (approximately 173%) better at texture filtering than the GeForce GT 230. (explain)
Pixel RateThe Radeon HD 4670 1GB is a lot (more or less 36%) better at anti-aliasing 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 data (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per 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 calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many 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.
