Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon R9 390 8G
IntroThe GeForce GTX 660 Ti uses a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 memory is set to run at a speed of 1500 MHz on this card. It features 1344 SPUs along with 112 Texture Address Units and 24 Rasterization Operator Units.Compare all of that to the Radeon R9 390 8G, which uses a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory works at a speed of 1500 MHz on this card. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 390 8G should perform much faster than the GeForce GTX 660 Ti in general. (explain)
Texel RateThe Radeon R9 390 8G will be quite a bit (approximately 56%) more effective at anisotropic filtering than the GeForce GTX 660 Ti. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 390 8G is a better choice, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
