Compare any two graphics cards:
GeForce GTX 460 vs Radeon HD 4670 1GB
IntroThe GeForce GTX 460 makes use of a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this particular card. It features 336 SPUs along with 56 Texture Address Units and 24 Rasterization Operator Units.Compare those specifications to the Radeon HD 4670 1GB, which features core clock speeds of 750 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs as well as 32 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 460 should perform quite a bit faster than the Radeon HD 4670 1GB in general. (explain)
Texel RateThe GeForce GTX 460 will be quite a bit (approximately 58%) more effective at texture filtering than the Radeon HD 4670 1GB. (explain)
Pixel RateThe GeForce GTX 460 should be quite a bit (approximately 170%) more effective at AA than the Radeon HD 4670 1GB, and able to handle 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 (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 ability to reach the max fill rate.
