Compare any two graphics cards:
GeForce 9800 GX2 vs Radeon R9 M295X
IntroThe GeForce 9800 GX2 has a clock speed of 600 MHz and a GDDR3 memory frequency of 1000 MHz. It also uses a 256-bit memory bus, and makes use of a 65 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare all of that to the Radeon R9 M295X, which has GPU clock speed of 750 MHz, and 4096 MB of GDDR5 memory running at 1375 MHz through a 256-bit bus. It also features 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 M295X should theoretically be a lot better than the GeForce 9800 GX2 in general. (explain)
Texel RateThe Radeon R9 M295X will be a lot (more or less 25%) faster with regards to texture filtering than the GeForce 9800 GX2. (explain)
Pixel RateThe Radeon R9 M295X is a lot (about 25%) faster with regards to full screen anti-aliasing than the GeForce 9800 GX2, and should be able to handle higher screen resolutions more effectively. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
