Compare any two graphics cards:
Radeon HD 3650 vs Radeon R9 M270X
IntroThe Radeon HD 3650 comes with a GPU core clock speed of 725 MHz, and the 1024 MB of GDDR4 memory is set to run at 800 MHz through a 128-bit bus. It also is made up of 120(24x5) Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.Compare those specifications to the Radeon R9 M270X, which makes use of a 28 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R9 M270X should be 181% quicker than the Radeon HD 3650 overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon R9 M270X should be a lot (about 400%) faster with regards to AF than the Radeon HD 3650. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 M270X is superior to the Radeon HD 3650, 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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the 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 number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
