Compare any two graphics cards:
Geforce GTX 760 vs Radeon HD 4670 1GB
IntroThe Geforce GTX 760 comes with a GPU core clock speed of 980 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1502 MHz through a 256-bit bus. It also features 1152 Stream Processors, 96 Texture Address Units, and 32 Raster Operation Units.
Compare all that to the Radeon HD 4670 1GB, which makes use of a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM runs at a speed of 1100 MHz on this card. It features 320(64x5) SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 760, in theory, should perform much faster than the Radeon HD 4670 1GB in general. (explain)
Texel RateThe Geforce GTX 760 will be a lot (approximately 292%) better at texture filtering than the Radeon HD 4670 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Geforce GTX 760 is superior to the Radeon HD 4670 1GB, by far. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result 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, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many 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.
