Compare any two graphics cards:
GeForce 9800 GT 1GB vs Radeon R9 M270X
IntroThe GeForce 9800 GT 1GB uses a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this specific card. It features 112 SPUs along with 56 TAUs and 16 ROPs.Compare those specifications to the Radeon R9 M270X, which makes use of a 28 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon R9 M270X should theoretically be a lot superior to the GeForce 9800 GT 1GB overall. (explain)
Texel RateThe GeForce 9800 GT 1GB is just a bit (about 16%) faster with regards to AF than the Radeon R9 M270X. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M270X 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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
