Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon R9 380 4G
IntroThe GeForce GTX 1060 3GB features a GPU clock 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 SPUs, 72 Texture Address Units, and 48 ROPs.
Compare all of that to the Radeon R9 380 4G, which comes with GPU clock speed of 970 MHz, and 4096 MB of GDDR5 RAM set to run at 1425 MHz through a 256-bit bus. It also is comprised of 1792 SPUs, 112 Texture Address Units, and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 1060 3GB should be a small bit faster than the Radeon R9 380 4G in general. (explain)
Texel RateThe Radeon R9 380 4G is just a bit (approximately 0%) faster with regards to texture filtering than the GeForce GTX 1060 3GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB will be quite a bit (about 133%) more effective at FSAA than the Radeon R9 380 4G, 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: Bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends 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.
