Compare any two graphics cards:
Radeon HD 4770 vs Radeon R5 M330
IntroThe Radeon HD 4770 comes with a core clock frequency of 750 MHz and a GDDR5 memory speed of 800 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Radeon R5 M330, which comes with core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon HD 4770 should be 256% quicker than the Radeon R5 M330 overall, due to its higher data rate. (explain)
Texel RateThe Radeon HD 4770 will be a little bit (more or less 17%) more effective at AF than the Radeon R5 M330. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 4770 is superior to the Radeon R5 M330, 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 max amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units 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 maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
