Compare any two graphics cards:
Radeon HD 4850 X2 1GB vs Radeon R7 M265
IntroThe Radeon HD 4850 X2 1GB makes use of a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR3 memory is set to run at a speed of 993 MHz on this card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.Compare that to the Radeon R7 M265, which makes use of a 28 nm design. AMD has clocked the core speed at 725 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this particular model. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon HD 4850 X2 1GB should theoretically be a lot superior to the Radeon R7 M265 in general. (explain)
Texel RateThe Radeon HD 4850 X2 1GB is much (approximately 187%) better at anisotropic filtering than the Radeon R7 M265. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 4850 X2 1GB is a better choice, by a large margin. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
