    Never thought it would really be 29% IPC improvement. Realistically if they improve about 10% IPC and have higher clock, we can see that 25% performance increase, which is still very nice. On a side note though, I think that AMD should temper the expectations as it's better to be surprised on release than to be disappointed. They often go big on promises without clarifying what their numbers actually mean.

    I agree, though when Zen was first released, it actually overall performed better than they claimed, and that was before scheduler improvements. I'd still take a 29% improvement with a grain of salt (at the very least, it's obviously application-specific) but I don't think they're going to shoot themselves in the foot like they did with Bulldozer, Steamroller, and Piledriver (by the time Excavator came out, nobody cared what they had to say).
    As I've said before, I'm sure this hefty improvement mostly comes down to AVX. AMD's current products have much room for improvement there and I recall that they were going to improve it.

    They DID clarify it, saying it was only for a specific benchmark and not applicable across all applications (see my link at the top of this page).

    All IPC claims are application specific and are not applicable across all applications, so it's really not that useful of a "re-clarification", other then to say it's not the "average" IPC increase.

    Good. May be they will force Intel to lower their prices, and I will buy next extreme edition CPU and motherboard.

    I think i am fine my 1600 , all i did was match the 1600x stock settings and left it there really , now the 3600 should have same tdp or lower so if anything might be even better .

    my thinking is, you never know how much cores they pack in there and how much more juice it will need. Load dependent it might have more need for offset regulation etc.

    I heard it was around a 15% increase in IPC, which is still pretty good. Combined with AMD's higher throughput SMT, they are finally going to give Intel a run for their money next year. Intel likely won't conceivably pull back ahead until Ice Lake.

    agreed on the other hand if the leaks are true it seems that the 3600 will be another 6 core , i am currently around 95watts tdp .. i am pretty sure my mb will degrade rapidly if i push 150 watts .... but if it stays at 6 cores indeed it might be 65 watts chip i can hardly see it going past 95 tdp but we will see :)

    Zen+ was Ryzen 2nd gen. Zen 2 will be Ryzen 3rd gen if they stick with the name. Calling it Ryzen 3 will be confusing though since that's what they already name their low end chips.

    Consumer CPUs are Ryzens, Architecture is Zen. Nothing to be confused about.

    That depends entirely on the consumers. All the Zen+ Ryzens are often referred to as Ryzen 2 was my point. You can see then how that could lead to confusion with the next generation.

    thats because Zen =/= Ryzen

    Ryzen 2 = Zen+
    Ryzen 3 = Zen 2

    @Amaze / @FranciscoCL : You are confusing yourself by ignoring actual naming.
    I do not have "Ryzen 7" or "Ryzen 2700X", I have "Ryzen 7 2700X". I bolded and underlined number which shows release generation.
    If you think that people buying new CPU will confuse "Ryzen 3 1200" and "Ryzen 7 3700X" you are mistaken. AMD could have leave out standalone 3/5/7 which is duplicate anyway, but system builders are not demented.
