AMD Radeon 5000 refers to a series of GPUs and so does R5 in terms of APU graphics and /desktop mobility graphics. Without specific parts listed, it's difficult to say which is more powerful. Which parts are you looking at, can you provide links?
Oh man got what you mean, and i have another question please , sorry for asking too much just last question , i am not good in Nvidia graphics, so is Nvidia 740M better or 840M ?
The simplest Answer would be on ether the AMD cards or the Nvidia ones is the not necessarily better just Newer the R5 is a newer GPU in apu where as 5000HD is an older line. Same with Nvidia The 840M is a newer line where as the 740M is the older one!
No it is not the same. R5 graphics refers to the integrated graphics card inside an APU.
