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 frequency of 1502 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is comprised of 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.
Compare all of that to the Radeon HD 4670 1GB, which has a core clock frequency of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory speed of 1100 MHz. It also uses a 128-bit memory bus, and uses a 55 nm design. It features 320(64x5) SPUs, 32 Texture Address Units, and 8 Raster Operation 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 overall. (explain)
Texel RateThe Geforce GTX 760 will be much (approximately 292%) better at anisotropic filtering than the Radeon HD 4670 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Geforce GTX 760 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that are applied per second. This 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 applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
