Compare any two graphics cards:
GeForce 9800 GT 512MB vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce 9800 GT 512MB has core speeds of 600 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.Compare all that to the Radeon HD 6670 (OEM) 1GB, which features a core clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It features 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6670 (OEM) 1GB should perform a bit faster than the GeForce 9800 GT 512MB overall. (explain)
Texel RateThe GeForce 9800 GT 512MB should be quite a bit (approximately 75%) better at AF than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe GeForce 9800 GT 512MB is much (about 50%) better at anti-aliasing than the Radeon HD 6670 (OEM) 1GB, and also able to handle higher resolutions without slowing down too much. (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 largest amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
