Compare any two graphics cards:
Geforce GTX 760 vs Radeon HD 4670 1GB
IntroThe Geforce GTX 760 has a core clock speed of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It features 1152 SPUs, 96 Texture Address Units, and 32 ROPs.
Compare those specs 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 RAM. It features 320(64x5) SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Geforce GTX 760 should in theory be much superior to the Radeon HD 4670 1GB in general. (explain)
Texel RateThe Geforce GTX 760 is a lot (about 292%) more effective at AF than the Radeon HD 4670 1GB. (explain)
Pixel RateIf running with a high resolution 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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
