Compare any two graphics cards:
GeForce 9800 GT 1GB vs Radeon R9 M390X
IntroThe GeForce 9800 GT 1GB uses a 65/55 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this particular card. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare all that to the Radeon R9 M390X, which comes with a clock speed of 723 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 M390X should in theory be much superior to the GeForce 9800 GT 1GB in general. (explain)
Texel RateThe Radeon R9 M390X is a lot (approximately 175%) more effective at AF than the GeForce 9800 GT 1GB. (explain)
Pixel RateThe Radeon R9 M390X should be quite a bit (approximately 141%) faster with regards to AA than the GeForce 9800 GT 1GB, and also should be capable of handling higher screen resolutions without slowing down too much. (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 maximum amount of data (in units of MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core 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 processed in a second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
