Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 760
IntroThe Geforce GTX 670 features a core clock speed of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1344 SPUs, 112 TAUs, and 32 ROPs.
Compare all of that to the Geforce GTX 760, which makes use of a 28 nm design. nVidia has set the core frequency at 980 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this particular card. It features 1152 SPUs along with 96 Texture Address Units and 32 Rasterization Operator Units.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The Geforce GTX 760 should in theory perform just a bit faster than the Geforce GTX 670 overall. (explain)
Texel RateThe Geforce GTX 670 will be a bit (more or less 9%) faster with regards to anisotropic filtering than the Geforce GTX 760. (explain)
Pixel RateThe Geforce GTX 760 will be just a bit (more or less 7%) faster with regards to FSAA than the Geforce GTX 670, and also will be capable of handling higher resolutions better. (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 data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
