Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon R7 250
IntroThe GeForce 8600 GT 512MB DDR2 has a GPU core speed of 540 MHz, and the 512 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the Radeon R7 250, which features clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 250 should perform a lot faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe Radeon R7 250 will be quite a bit (more or less 178%) better at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R7 250 is superior to the GeForce 8600 GT 512MB DDR2, by a large margin. (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 data (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This number 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
