Compare any two graphics cards:
Radeon HD 6670 (OEM) vs Radeon R9 M395X
IntroThe Radeon HD 6670 (OEM) has a GPU clock speed of 800 MHz, and the 512 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also is comprised of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.Compare all that to the Radeon R9 M395X, which comes with clock speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M395X should theoretically perform a lot faster than the Radeon HD 6670 (OEM) overall. (explain)
Texel RateThe Radeon R9 M395X should be a lot (approximately 382%) more effective at AF than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe Radeon R9 M395X is much (approximately 262%) more effective at anti-aliasing than the Radeon HD 6670 (OEM), and also will be capable of handling higher 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 data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range 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 calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 ability to reach the maximum fill rate.
