Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 760
IntroThe Geforce GTX 670 has a GPU clock speed of 915 MHz, and the 2048 MB of GDDR5 memory runs at 1500 MHz through a 256-bit bus. It also is made up of 1344 Stream Processors, 112 Texture Address Units, and 32 ROPs.
Compare those specifications to the Geforce GTX 760, which has a clock frequency of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It features 1152 SPUs, 96 TAUs, and 32 ROPs.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The Geforce GTX 760 should in theory perform a little bit faster than the Geforce GTX 670 in general. (explain)
Texel RateThe Geforce GTX 670 will be a small bit (about 9%) faster with regards to anisotropic filtering than the Geforce GTX 760. (explain)
Pixel RateThe Geforce GTX 760 will be a little bit (about 7%) more effective at anti-aliasing than the Geforce GTX 670, and also should be capable of handling 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.
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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core 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 in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
