Compare any two graphics cards:
Geforce GTX 760 vs Geforce GTX 770
IntroThe Geforce GTX 760 makes use of a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 RAM works at a frequency of 1502 MHz on this card. It features 1152 SPUs along with 96 TAUs and 32 ROPs.
Compare those specifications to the Geforce GTX 770, which makes use of a 28 nm design. nVidia has set the core frequency at 1046 MHz. The GDDR5 RAM is set to run at a speed of 1753 MHz on this model. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 770 should be 17% faster than the Geforce GTX 760 in general, due to its higher data rate. (explain)
Texel RateThe Geforce GTX 770 is much (approximately 42%) faster with regards to anisotropic filtering than the Geforce GTX 760. (explain)
Pixel RateIf using a high resolution is important to you, then the Geforce GTX 770 is the winner, but not 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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
