Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon R9 380 2G
IntroThe GeForce GTX 1060 3GB has a core clock frequency of 1506 MHz and a GDDR5 memory speed of 2000 MHz. It also makes use of a 192-bit bus, and makes use of a 16 nm design. It is comprised of 1152 SPUs, 72 TAUs, and 48 Raster Operation Units.
Compare that to the Radeon R9 380 2G, which features core clock speeds of 970 MHz on the GPU, and 1425 MHz on the 2048 MB of GDDR5 memory. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 1060 3GB should be 8% faster than the Radeon R9 380 2G overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon R9 380 2G will be a small bit (about 0%) more effective at texture filtering than the GeForce GTX 1060 3GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB will be a lot (about 133%) faster with regards to full screen anti-aliasing than the Radeon R9 380 2G, and should be capable of handling higher 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 information (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
