Question

Why are people praising AMD Ryzen 9 3950X over the i7900k?

At first I thought people were praising the AMD Ryzen 3950x due to it's price and since I'm looking to build another computer I thought I was in for a bargain. That is until I checked the price of the AMD Ryzen 9 3950x and saw it's £689. So why all the rave for AMD Cpu's? The Intel i7 9700k has better performance in games and it's cheaper at £570.

    My 7700k at 4.8ghz bottlenecks my RTX2080 in a few vr games using a Valve Index.


    Which specific games and how many hz are you using? You'd need to see below 90 fps even if using 50% res (or lower if that's possible). 

    Compared to my CV1, Index is extremely much more gpu bottlenecked with my GTX 1080.

    I just saw that intel are bringing out the intel 10900KF, but it still has 14nm and I was hoping for 7nm. I currently have a Skylake 6700 and a Geforce 2080ti. Do you think it's best if I just go with a i7 9700k for my upgrade given the intel 10900KF, is only going to have about 10% better performance in games.


    CPU upgrades have been dissapointing since the sandy bridge era imo 
    With a tasty overclock my i7 5820k from 2015 is still fab for gaming and whilst I am not certain, I am hopefull it will see out 1 more upgrade with a 3080/3080ti
    Hell at a push my arcade pc which is running my sandy bridge i5 2500k (also overclocked) can still run any game I have tried on it.

    Personally IF I was upgrading today I would go Ryzen but tbh I don't think it makes much difference if all you want is gaming. I just want to support the underdog for a change and I don't believe AMD will do it for gpu

    I changed from a 7700K to a 2700 a couple of years ago - just as an experiment - and stuck with the AMD CPU as it does offer a few spare cores when running several apps.
    Not had any obvious issues gaming, no slower or faster, so no gripes.
    I may go for the 3700 or 3900 later as I have the X570 chipset so there would be gains over the 2700, plus 7nm architecture to play around with.
    The 2080 Super appears to be a nice compromise too, handles 4K gaming nicely and VR too, although I suppose one day I'll have to run actual benchmark tests to see if the combo is as good as it appears :)

    Really? Wow that surprises me unless you mean FSX or other highly inefficient older title

    I'd support the underdog if they weren't more expensive than the top dog  :D

      I think some of peoples perceptions of what's better is familiarity and unconscious bias. Some of it has to do with the games they are playing. I think it's safe to say there is nothing you can do with one that you can't do with the other without really noticing a difference unless you benchmark. The computer I built last year was the first AMD machine I've built since the 486 days. 
     I thought it would be nice to have more cores because my digital audio workstation software finally got to the point that it was using cores more efficiently.  I'm happy with my choice. I get a few more tracks without having to bounce or freeze.    I may have got a few fps more in some VR games if I went for an equivalent  Intel processor,  probably a few less in other games 
     One thing I appreciate AMD for is providing good competition to Intel throughout the years. Without them I believe Intel would have become complacent. 
      I would say a well chosen motherboard and RAM combo and getting the RAM optimized will make more of a difference in performance than choosing AMD or Intel .
     Here are some gaming benchmarks to show how close those two are.

    - and then there's potential compatibility issues, maybe it's just me, but I've noticed quite a few AMD users with Rift-S problems (but if that is true it may of course be caused by mainboard components).

    With Intel I get the feeling that I can sleep better at night and don't have to worry about anything, lol. 

    I might consider AMD, but only when they dominate clearly when it comes to gaming performance and most (Steam high-end) users have an  AMD cpu. Right now I'd feel like a beta tester using a Ryzen cpu ;)

    So I would need to do more research if I was actually planning to upgrade so i could be wrong but the little I have followed is that the Ryzen 3700x takes some beating in the gaming bang for your buck 
    Sure for benchmarking willy waving it may fall short, but I am not sure you would gain any actual noticeable improvement when it comes to gaming experience over spending more.   I think I have seen that chip before things went silly recently for the bright side of £250

    Like I said I am hoping I can eek another GPU generation out of my 5820k. I got lucky. I was gonna buy a 4 core i7 but my 6 core CE up In a 2015 black Friday bundle I could not. refuse . At the time the extra 2 cores didn't really help me but I think it has come into its own the last few years.

     Fair enough, I'm glad you're sleeping well. Perhaps consider that both the PlayStation and X-box use AMD exclusively, I just can't see AMD as the underdog in the gaming category

    @bigmike20vt - I'm was comparing the highend intel and AMD Cpu's. I'm haven't looked at the pricing for the mid range Cpu's, so AMD might come out top when it comes to pricing in that range.
