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 features a 256-bit bus, and makes use of a 55 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare all that to the Radeon HD 4670 1GB, which has clock speeds of 750 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR4/GDDR3/DDR3/DDR2 RAM. It features 320(64x5) SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4670 1GB should be 10% faster than the GeForce GTS 150 in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTS 150 is quite a bit (more or less 97%) better at anisotropic filtering than the Radeon HD 4670 1GB. (explain)
Pixel RateThe GeForce GTS 150 should be quite a bit (approximately 97%) better at FSAA than the Radeon HD 4670 1GB, and will be able to handle higher screen resolutions more effectively. (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 megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
