Compare any two graphics cards:
Radeon HD 6450 (OEM) vs Radeon R9 M395X
IntroThe Radeon HD 6450 (OEM) has a GPU clock speed of 625 MHz, and the 512 MB of GDDR3 memory is set to run at 800 MHz through a 64-bit bus. It also is comprised of 160 SPUs, 8 TAUs, and 4 ROPs.Compare those specifications to the Radeon R9 M395X, which features core clock speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs along with 128 Texture Address Units 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 quite a bit better than the Radeon HD 6450 (OEM) in general. (explain)
Texel RateThe Radeon R9 M395X is quite a bit (more or less 1751%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe Radeon R9 M395X will be a lot (about 825%) more effective at AA than the Radeon HD 6450 (OEM), and also able to handle higher screen resolutions without losing too much performance. (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 largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
