Compare any two graphics cards:
Radeon HD 4670 512MB vs Radeon HD 5670
IntroThe Radeon HD 4670 512MB uses a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory is set to run at a frequency of 1000 MHz on this model. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 5670, which comes with GPU clock speed of 775 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also features 400(80x5) Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 5670 should theoretically be quite a bit better than the Radeon HD 4670 512MB overall. (explain)
Texel RateThe Radeon HD 4670 512MB should be much (approximately 55%) faster with regards to AF than the Radeon HD 5670. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 5670 is superior to the Radeon HD 4670 512MB, not by a very large margin though. (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 maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied 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 graphics 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 that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
