Compare any two graphics cards:
GeForce GTX 1060 3GB vs Geforce GTX 690
IntroThe GeForce GTX 1060 3GB features a GPU core speed of 1506 MHz, and the 3072 MB of GDDR5 RAM runs at 2000 MHz through a 192-bit bus. It also is comprised of 1152 Stream Processors, 72 Texture Address Units, and 48 ROPs.
Compare all that to the Geforce GTX 690, which uses a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this specific model. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 690, in theory, should be much faster than the GeForce GTX 1060 3GB in general. (explain)
Texel RateThe Geforce GTX 690 will be much (more or less 116%) more effective at anisotropic filtering than the GeForce GTX 1060 3GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 1060 3GB is superior to the Geforce GTX 690, by a large margin. (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.
One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.
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 information (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling 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 write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
