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

Well AMD did compare it to the 6900K in one benchmark right? If performance falls between the 6700K and the 6900K at the £300 price point then that will be a winner as well from a price/performance perspective.

Time will tell I guess. But more interesting than the previous Bulldozer and Excavator announcements that's for sure.
 
If it's anywhere near the i7s and a bit cheaper with 8 cores I'd definitely be interested. My 2500k has lasted years I'd expect with that performance Zen would last me even longer.

Right, clock for clock (3Ghz) in Blender, Zen finished fractionally ahead of the i7 6900K.
 
Depending on how the pipeline is set up, core for core I think Zen will beat some of Intel's chips in some situation and not in others. A little like we see between the various architectures now.

If the chip is 40% faster then a FX8, that will put it right in the mix with the i7 chips. Core of core I think Skylake will have an edge over Zen as we have to keep in mind this brand new silicon built in a brand facility and AMD will be under pressure to AM4 established.

Obviously in any multitreaded situation the 8 core 16 thread chip will most likely thrash any a 4 core 8 thread chip into next week.

Which is more than good.
So, suddenly going to i7 6700K performance would be very meh :p

But I guess this is part of the problem when people talk with saying i7 as an absolute. As that can mean anything from 4 physical cores to 10.

Nothing has moved on the Intel side. Why so much overestimation of i7 performance.

Yawn.

Skylake with DDR4 has ~25% IPC increase compared to Sandy, and it's nearly 70% if the task is tailored to all the improvements:

Also Zen is 40% faster than Excavator, not Piledriver.

So it's more like ~68% faster than an FX8 (Excavator being ~20% higher IPC than Piledriver).

Faster in few situation, but clock speed has gone up and over clocking headroom has gone down. Take most of the unless benchmarks away and very little has changed. Price have also gone up considerably.

You should stop saying Skylake is 70% faster. That's very misleading.

"meh" at a lower price would sell because in this context "meh" is far better than needed for most customers. What mainstream software of any kind is CPU-limited on an i7 6700K? No doubt there are some scenarios, but they're not common enough to badly impact sales.

Top end gets the media attention and the big profit margins, but there's a lot of sales in the midrange and the low end.

This is an entirely accurate statement.

Also if you check benchmark sites who do minimum FPS as well as average, Skylake has considerably higher minimum FPS than sandy bridge.

Intel may not have made drastic improvements over the past few years, but Skylake is undoubtedly better than sandy/ivy/etc.

Speculation.

An FX8320 is more than needed in the context you're posting. You couldn't say that the FX8320 has been killing it.
It's OEM's where AMD needs to get the product in to. So we'll see what it offers when it comes out.

Pretty sure they're the same after accounting for inflation, aside from when people are clamouring for them and supplies are low just after launch.

The iGPU is the 3-4 times faster in Skylake (and power efficiency is still better), perhaps Intel should market them as APU so that people will remember that the CPU is only half of the product.

Maybe, or sell unlocked chips without the IGP for less money like they used to, because many people never use the IGP.

Power use has gone up with Intel and not many people care about efficiency of single chips.
 
I hope Intel hurry up with that InGaAs stuff, it's literally the only thing on the horizon that is remotely interesting/worthwhile.

Zen+ is only another (at best) 10% above Zen 1 and then Intel's usual bilge in the neverending banality of the Lake family. But we will likely have to wait until 2020 to see any kind of progress. Joy.
