The new 3rd Gen 7nm Ryzen 3000 Zen2 series is significantly different from and vastly improved upon its predecessors viz. Zen and Zen+ so perhaps it is time for its own discussion thread.

Summary

1. 7nm architecture (Intel is stuck at 14nm+++ ad nauseum... )
2. PCI-e v4 (Intel is stuck at v3)
3. higher CPU clocks - both base and boost (over 4+ GHz and onwards... )
4. higher DDR4 clocks (over 3733MHz and onwards... )
5. more cores (up to 16!) and threads (up to 32!)
6. AVX-256 instructions
7. AM4 backward compatibility!!! (screw you pin twiddling Intel)
8. 2 x L3 cache size
9. great performance jump - for both single and multi core
10. fantastic cost benefits - for users (and AMD too)

Without AMD's Ryzen, we would all be still stuck at 4 cores mainstream and even going backwards with Intel's removal of hyperthreading (i7-9700K) and paying through the nose for them. Intel chip vulnerabilities and fixes already have owners uncontrollably losing performance over time, we don't need more of Intel's gimmicky nonsense to lose even more.

OK, time to share your experience and encourage the present fence sitters to reconsider their next CPU buying decision.

Backward compatibility is no idle claim...

Motherboard used is an old model from the very OG 2017 Ryzen launch, the Asus X370 Crosshair VI Hero... no problem performing while running the new Ryzen 3600 with RAM@DDR4-3600 using 'budget' Hynix RAM.

The sweet spot for RAM speed is 3733 MHz or 3600 MHz. Beyond that, performance actually goes down as the Infinity Fabric clock will get cut in half so anything higher than 3733/3600 MHz is pointless.

Yes, highly dependent on the IMC of each chip too. Some can run higher than others but most are 3600/3733.

Indeed running faster RAM is not always making the system faster but it's not totally pointless if one is targeting specific needs like binning high speed RAM. You can't even do that on most earlier Ryzens.

OK, but not many folks here will be spending their time binning high speed RAM.

Call it an additional benefit without any additional cost, maybe.

kimsix · 17-07-2019, 11:01 AM

Got 2x16 crucial 3200 $215, tiagong is e-die. Tempting to change from Intel to amd but got 2 disappointments, banleong markup gao gao $200 for their CH8, the second is ryzen 3 like zero OC left. Intel at least you can OC some for normal usage.

If Intel slash the x299 cpu prices... I see x299 boards are affordable now, evga ftwk only $460, overall going from x99 to x299 can be cheaper.

High chance Micron E die esp. if there is AES in the model number.

16GB is also likely dual rank, not sure if Ryzen 3K has improved handling of these RAM.

Intel will be forced to make a comeback and comeback they will.

With the 7nm process node, AMD just managed to meet performance parity in IPC and only pulling ahead in multi-core performance.

With AMD finally competing, we can only now benefit with lower prices and better value, enjoy while it lasts.

If you think the latest X570 motherboard is expensive ? Fret not cos all AM4

motherboards are 3rd Gen Ryzen CPU compatible including b350 and B450 ones

In other words when buying a new build, If wan to save money can just buy Ryzen 3600 +

B350 Tomahawk and flash the BIOS. It is backward compatible

kimsix · 17-07-2019, 02:27 PM

Crosshair 7 only $350 at Amazon app
Crosshair 8 only $540 from Newegg.
Ok to use x470 for 16 cores?
Since Ryzen cannot over clock at all?

NMSS_2 · 17-07-2019, 03:25 PM

got rumours on setting the correct timing for ram and cpu could possibly get 5-10% performance.

Can consider HyperX Fury. I was able to take mine from 2667Mhz to 3333MHz @ CL16, 1.35V.
