Compare any two graphics cards:
GeForce 9800 GTX+ vs Radeon R9 M395X
IntroThe GeForce 9800 GTX+ comes with a GPU core clock speed of 738 MHz, and the 512 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.Compare all that to the Radeon R9 M395X, which features core speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R9 M395X should perform much faster than the GeForce 9800 GTX+ in general. (explain)
Texel RateThe Radeon R9 M395X will be quite a bit (more or less 96%) faster with regards to AF than the GeForce 9800 GTX+. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 M395X is superior to the GeForce 9800 GTX+, and very much so. (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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once 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 higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 video card could possibly write to its local memory in a 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 clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
