Compare any two graphics cards:
Radeon HD 6450 (OEM) 1GB vs Radeon R7 M265
IntroThe Radeon HD 6450 (OEM) 1GB comes with a GPU core speed of 750 MHz, and the 1024 MB of GDDR5 RAM is set to run at 900 MHz through a 64-bit bus. It also features 160 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.Compare all that to the Radeon R7 M265, which makes use of a 28 nm design. AMD has set the core speed at 725 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this card. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R7 M265 will be 11% faster than the Radeon HD 6450 (OEM) 1GB in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon R7 M265 is a lot (about 190%) better at texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R7 M265 is a better choice, and very much so. (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 (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
