why amd fx processors are behind intel core CPU's with respect to single core performance?


Oct 8, 2015
for example lets take fx 4300. it has six cores, six threads. whereas i3 6100 has two cores 4 threads. on paper amd is superior to intel in almost every aspect. yet why is i3 far superior in performance especially in single-core. what makes amd slow despite the more number of cores and threads? i read about this on many sites but was difficult for me to grasp. please explain in an easy way
if you look at cpu for dummies if it still online. or read up on history of intel and amd. you find that today intel x86 core info is about the same as the one in the old x286 pc. intel eng from the time x286 to days cpu the cpu core tech is still the same. it gotten faster and more refined over the years. in the 80-90 intle could not make all of the cpu chips (386/486) that the market wanted. so some of chips were made by amd. amd then tried to get into the cpu biz there were some lawsuits you can google amd vs intel to find old info about them. amd won and was able to keep making cpu chips but lost intel eng and info to help them. amd also at the time had a chip foundry and had just gotten ati as gpu vendor. amd had issues on top level where to take the company and where to spend money. there were misteps at amd. the older fx cpu was not a bad cpu core. amd killed it off and for a few years have tried more then one core design few of them worked others were flops. the new amd eng and top brass looks like they know now that amd may never bet intel in raw speed in core tech. but there beating intel now on there apu chips.
there used in gaming systems. if the new zen cpu works as well on paper as it does in real life. going to see a lot of laptop vendor on low end start using these chips. they have better gaming and gpu performace then the lower end intel cpu. if amd sticks with zen and can come out with better cpu it may catch up with intel. intel right now has hit a wall with shrinking there cpu to lower the voltage. had issue getting to 14mm with brodwell and skylake.
it may take intel a bit of time to get to 10mm and 8mm. these are the sizes they want for curby lake and the next cpu after skylake. if may take intell a few years now to hit those sizes. so intel skylake going to be around now for more then 18 months tic/toc cycle that intel uses to have.
