Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon R9 M385X
IntroThe GeForce 8600 GT 512MB DDR2 has a GPU clock speed of 540 MHz, and the 512 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 ROPs.Compare all that to the Radeon R9 M385X, which has a clock speed of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M385X will be 650% quicker than the GeForce 8600 GT 512MB DDR2 overall, due to its greater data rate. (explain)
Texel RateThe Radeon R9 M385X should be quite a bit (approximately 613%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe Radeon R9 M385X should be quite a bit (approximately 307%) faster with regards to full screen anti-aliasing than the GeForce 8600 GT 512MB DDR2, and also should be able to handle higher screen resolutions while still performing well. (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 (measured in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of 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.
