Compare any two graphics cards:
GeForce GTS 150 vs Radeon HD 4670 1GB
IntroThe GeForce GTS 150 features a core clock speed of 740 MHz and a GDDR3 memory frequency of 500 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 4670 1GB, which has a GPU core clock speed of 750 MHz, and 1024 MB of GDDR4/GDDR3/DDR3/DDR2 memory running at 1100 MHz through a 128-bit bus. It also is comprised of 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4670 1GB should perform just a bit faster than the GeForce GTS 150 overall. (explain)
Texel RateThe GeForce GTS 150 will be a lot (more or less 97%) faster with regards to texture filtering than the Radeon HD 4670 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTS 150 is superior to the Radeon HD 4670 1GB, and very much so. (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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
