Rumor: AMD's Zen 2, 7 nm Chips to Feature 10-15% IPC Uplift, Revised 8-core per CCX Design
A post via Chiphell makes some substantial claims on AMD's upcoming Zen 2 microarchitecture, built on the 7 nm process. AMD has definitely won the core-count war once again (albeit with a much more decisive blow to Intel's dominance than with Bulldozer), but the IPC battle has been an uphill one against Intel's slow, but sure, improvement in that area over the years. AMD did say, at the time they introduced the Zen architecture, that they had a solid understanding on Zen's choke points and its improveable bits and pieces - and took it to heart to deliver just that.
A 10 to 15% improvement should bring AMD close to Intel's Kaby Lake solutions in pure per-core, single-thread performance - with the possibility for higher performance in multithreaded workloads even at the same clocks and core counts, since AMD's SMT implementation and per-core communication seems to best that of even Intel's Coffee Lake chips. Add to that the sure clock increases AMD will bring to their Zen 2 parts - you can bet the power consumption and top frequency benefits for the 7 nm manufacturing process (some estimated 1.6X logic density, ~20% speed improvement, and ~40% power reduction compared to TSMC's 10 nm process) won't go to waste when they can be used for an even greater performance uplift.
Add to that the possibility -also posted via the Chiphell thread) of a per-CCX core-count increase of 8 cores per CCX (with 16-core parts being available for the consumer products) and a purely hypothetical claim for the performance crown now seems not only plausible, but likely.

Man, I love me some CPU Wars. :D
That said, 4% to 7% would still be more then what Intel achieved since like 4 - 5 years. It would close the gap quite a bit in single thread (not counting overclocking).
Still, and unless new Intel chips become less "overclocking friendly", even if AMD catches up to Intel in single thread, Intel will still be ahead for gaming. Ofc, if AMD suddenly manages to overclock more easily, this would change ...
Remember: Intel is having serious problems with their 10nm architecture(s), both in speeds they can achieve as well as yields. Add to that the security issues that forces to remove / adapt / alter the speculative prediction part of the processors, their performance could be further reduced (to which AMD is also affected, but not to the same extent).
Intel seems to be a "victim of their own high base clock / overclocks" because they are being hard pressed to come up with a chip that performs as well (preferably better) on 10nm compared to the current generation.
IPC is not the same as single threaded performance, and it's not the same as single threaded performance divided by clock speed either. It's simply Instructions Per Clock, one of several important aspects of single threaded performance. AVX is a type of SIMD (vector operations), and does not increase IPC, but it does massively increase performance for applications which use it.
Hardware unboxed did a video testing at least 15 programs and games at the same frequency and ryzen+ is on average 5% slower.i actually think it´s very doable. ryzen+ is just ryzen 1 with improved latencies and it has around a 3% ipc improvement. The base arquitecture is exactly the same. the 7nm node is a big jump in terms of the node itself and arquitecture. Probably will feature some deep changes on how zen works.
Back to the future news. I dig it. Happy as a clam with my new Gen 2 Ryzen rig!
2. 20-30% overall Single-Core increase - game over at everything else.
As for why "Intel would let this happen?" I am not really sure how you think corporations work. Intel is currently doing everything they can to fight AMD - this next set of processors will be all they can muster for at least a year. Why else do you think they are actually going to changing the thermal paste? That's the last trick they have left (besides anti-competitive BS that will surely begin soon).
They are stuck on 14nm, their next gen arch was meant for 10nm (and thus not ready for 14), and there is no sign this has changed. If they could do something else, then obviously they would! lol
I wan to see a simmilar AMD CPU going on stock air cooler on the same freq without any o.c.
I'll believe it when I see it.
+ before the "Ryzen" monicker it was just "Zen" with slides promising much better performance than we saw at launch.
8700K stood up against 1800X with no problems.
2700X won't have a chance against the upcoming 9900K, I expect AMD to release 2800X try filling the gap.
2019
Intel 10nm+ Icelake to fight AMD first gen 7nm Zen 2
Both are PCIe 4.0
Intel has DDR5 Memory
Intel has DMI 4.0
Intel has two New GPUs
2019 is going to be very interesting with Both Intel and AMD having new architecture and nm....
Both Intel Z470 chipset and AMD X570 support for 32 Threads Dual channel.
So expected 8, 12, 16 Cores over the next few years from both.
The core wars has begun!
Good lord do you think they can just launch a 16-core 10nm chip out of the blue?! Why?!
Do you not remember the long ramp-up of Broadwell?It's more likely than not they are being conservative. AMD is the one holding most of the cards at this point, and so they SHOULD be conservative. Companies tend to overestimate when they are not in a good position.
AMD brings Zen to the table Intel countered with Coffeelake. So AMD Bring Zen 2 on first gen 7nm. Intel is countering with Second gen 10nm+ “Q3 2019 so next September 2019 paper launch...
Till then we have 9900K and probably 2800X and Ryzen 3000 series (Q2 2019) next may.
Don't even expect good 7nm yields...
Look at 12nm yields with 2700X...
2700X 12nm
8 cores 4.3GHz 105 Watts
Vs
9900K 14nm+++
8 cores 5.0GHz 95 Watts
Do forget Intel superior IPC cores Coffeelake architecture provides.
I hope very much so AMD Zen 2 brings some good IPC improvements to the table, it only pushes Intel to build better CPUs... competition is healthy for all of us customers. Win wins
