*** AMD "Zen" thread (inc AM4/APU discussion) ***

We shall see. As I said if the 1800X overclocks to 4.4-4.5Ghz going to grab one without second thought next week.
Also I will do the same if it overclocks to 4.7Ghz at 4 cores, with the rest deactivated.

Very interesting that reddit link, suggests that X auto overclocking with decent cooling makes the 1800X the single threaded champ as well. I need to take a breath and wait for reviews, the hype train sure is strong...
 
Liking the rumours that Zen 2 (2018 stuff) will be even better. Think i may upgrade to a Zen 8c/16t cpu from my 5820k at that point if the IPC and clock speeds are increased even more for next years Zen releases.

If honest enough about it, nobody here is going to be in that user group. Outside the realms of stability testing, it's limited to a handful of professional application. Even then, it's questionable if you'd be looking at either consumer platform for this. It's taken users (and Intel) 3 years to adapt to the fact that when overclocking, the current some of these tests can pull limits the user. We've seen Handbrake, and that's as good a real world AVX test as any, especially in terms of power draw too.

The nail on the head is really that the performance is evidently competitive in most areas, and even the memory side should improve with firmware and microcode. Including I'd imagine, what is happening to some of the boards. How often really in the history of all things relevant, has VRM failure been due to design? It's almost always inherently firmware related. So short answer is in my opinion, give it 2 to 3 months, and you'll hopefully have a solid product, and an 8 core option that will make people question what they're really paying for elsewhere.

+1 thats a first for me, agreeing totally with anything you have said, well done though, i totally agree 100%

But this should not be a surprise to anyone keeping up with the news.

AMD has competitive IPC with Intel now so to beat the 7700K stock speed of 4.2/4.5 with the 1800X which is 3.6/4.0 it's not a huge overclock required to reach the same single threaded performance.

But its not a great cpu to pick a comparison with, 7700K can overclock a lot.

It's the 6, 8 and 10 core intel CPUs which take the real hits.

What are you talking about? The 7700K can't really 'overclock a lot', it's close to it's overclock limit with its stock boost frequency of 4.5Ghz out of the box. It's average overclock seems to be around 4.8-4.9Ghz, that's only 300-400Mhz more frequency making it a poor overclocker albeit the stock frequency is so high (because Intel had to do something to make people want to buy these Skylake+ CPUs :) )

On the other hand, the Broadwell-E's that you point out are better overclockers, even the 10-core 6950X has a turbo frequency of 3.5Ghz and can overclock to around 4.2-4.3Ghz, which is 700-800Mhz more frequency from overclocking.

An incorrect choice of words, the 7700K can overclock higher, the launch party overclock session managed just over 5GHz at -200 degrees on the 1800x.

The point being that the intel quad cores will have the frequency edge when frequency matters hence 7700k not being a great chip to claim as a competitor since the octa cores are prioritising threads not frequency.

I can't see the 1800x coming out as a particularly good choice for a gaming cpu at £490 vs the 7700k for example.

lol, yeah I thought you might like that one. Wouldn't get used to it ;). It's not really a matter of opinion that AVX512 has limited application, it's just a fact. As for the rest; I'll have to follow up with something hard hitting and cynical shortly :D

Hold on a sec. The Intel B-E 8-10 cores cannot do more than 5.2Ghz on LN2 either. The H-E 5960X can do 5.8Ghz but it's performance is beaten by the 5.2Ghz 1800X

And yes the 6700/7700K can do 7Ghz on LN2 but ONLY WITH 2 CORES!!!!!!! The rest are turned off.

If you could follow the quote trail please, you're taking my reply out of context.

1800x > intel 6,8 and 10 cores in a lot of things

1800x is not going to beat 7700k at everything because the 7700k has frequency advantage stock and with OC taken into account. 1800x needed LN to hit 5.2, 7700K can do it with air.

Hence... 1800X will not make a good comparison vs 7700K since the intel chip has different priorities

The cleanest comparisons are vs the heavy threaded lower clock intel chips.
