Compare any two graphics cards:
GeForce GTX 560 Ti vs Geforce GTX 760
IntroThe GeForce GTX 560 Ti has a clock speed of 822 MHz and a GDDR5 memory frequency of 1002 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It is comprised of 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.
Compare that to the Geforce GTX 760, which has GPU clock speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also is comprised of 1152 Stream Processors, 96 TAUs, and 32 Raster Operation Units.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Theoretically speaking, the Geforce GTX 760 should perform a lot faster than the GeForce GTX 560 Ti in general. (explain)
Texel RateThe Geforce GTX 760 is much (about 79%) more effective at anisotropic filtering than the GeForce GTX 560 Ti. (explain)
Pixel RateThe Geforce GTX 760 will be a bit (approximately 19%) faster with regards to FSAA than the GeForce GTX 560 Ti, and also should be able to handle higher screen resolutions while still performing well. (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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
