Compare any two graphics cards:
Radeon HD 4650 512MB vs Radeon R9 M395X
IntroThe Radeon HD 4650 512MB has a GPU clock speed of 600 MHz, and the 512 MB of DDR2 memory is set to run at 500 MHz through a 128-bit bus. It also is comprised of 320(64x5) Stream Processors, 32 TAUs, and 8 Raster Operation Units.Compare all that to the Radeon R9 M395X, which has core speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 M395X should theoretically be much superior to the Radeon HD 4650 512MB overall. (explain)
Texel RateThe Radeon R9 M395X should be much (more or less 382%) faster with regards to anisotropic filtering than the Radeon HD 4650 512MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R9 M395X 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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
