Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs Radeon R7 250
IntroThe GeForce 8600 GT 256MB DDR2 features core clock speeds of 540 MHz on the GPU, and 400 MHz on the 256 MB of DDR2 memory. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.Compare those specs to the Radeon R7 250, which comes with GPU core speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R7 250 should theoretically perform quite a bit faster than the GeForce 8600 GT 256MB DDR2 overall. (explain)
Texel RateThe Radeon R7 250 will be much (approximately 178%) more effective at anisotropic filtering than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R7 250 is the winner, 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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 are applied per second. This 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 video 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 number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
