Compare any two graphics cards:
Radeon HD 4830 1GB vs Radeon R7 M260X
IntroThe Radeon HD 4830 1GB comes with core clock speeds of 575 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR4 memory. It features 640(128x5) SPUs along with 32 TAUs and 16 Rasterization Operator Units.Compare all that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has clocked the core speed at 825 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this particular card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R7 M260X should theoretically be a small bit faster than the Radeon HD 4830 1GB in general. (explain)
Texel RateThe Radeon R7 M260X is a little bit (approximately 8%) more effective at anisotropic filtering than the Radeon HD 4830 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 4830 1GB is superior to the Radeon R7 M260X, 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 information (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
