Compare any two graphics cards:
Radeon HD 4850 1GB vs Radeon R5 M230
IntroThe Radeon HD 4850 1GB makes use of a 55 nm design. AMD has set the core speed at 625 MHz. The GDDR4 memory works at a speed of 993 MHz on this particular model. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.Compare all that to the Radeon R5 M230, which comes with core clock speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon HD 4850 1GB is 297% faster than the Radeon R5 M230 in general, because of its greater data rate. (explain)
Texel RateThe Radeon HD 4850 1GB should be quite a bit (approximately 60%) more effective at anisotropic filtering than the Radeon R5 M230. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 4850 1GB is superior to the Radeon R5 M230, 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 information (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, 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 amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
