Compare any two graphics cards:
Radeon HD 4830 1GB vs Radeon R7 M265
IntroThe Radeon HD 4830 1GB makes use of a 55 nm design. AMD has clocked the core speed at 575 MHz. The GDDR4 memory runs at a frequency of 900 MHz on this particular model. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 ROPs.Compare all of that to the Radeon R7 M265, which features core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the Radeon HD 4830 1GB should be quite a bit faster than the Radeon R7 M265 overall. (explain)
Texel RateThe Radeon HD 4830 1GB will be a little bit (about 6%) more effective at AF than the Radeon R7 M265. (explain)
Pixel RateThe Radeon HD 4830 1GB is quite a bit (about 59%) better at AA than the Radeon R7 M265, and able to handle higher 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 maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
