Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs Radeon R9 M295X
IntroThe GeForce 8600 GT 256MB DDR2 uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 RAM works at a speed of 400 MHz on this model. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.Compare all of that to the Radeon R9 M295X, which features GPU clock speed of 750 MHz, and 4096 MB of GDDR5 RAM set to run at 1375 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M295X, in theory, should be a lot faster than the GeForce 8600 GT 256MB DDR2 overall. (explain)
Texel RateThe Radeon R9 M295X is a lot (approximately 1011%) more effective at texture filtering than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateThe Radeon R9 M295X should be quite a bit (about 456%) more effective at anti-aliasing than the GeForce 8600 GT 256MB DDR2, and also able to handle higher 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: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 can be processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
