Compare any two graphics cards:
Radeon HD 4670 512MB vs Radeon R9 M385X
IntroThe Radeon HD 4670 512MB comes with core clock speeds of 750 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the Radeon R9 M385X, which has GPU core speed of 1100 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon R9 M385X should theoretically be quite a bit better than the Radeon HD 4670 512MB overall. (explain)
Texel RateThe Radeon R9 M385X should be quite a bit (about 157%) better at anisotropic filtering than the Radeon HD 4670 512MB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 M385X is a better choice, by far. (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 megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
