***OFFICIAL*** Ryzen 5000 / Zen 3 Launch Thread REVIEWS BEGIN PAGE 39

[amrnuke]

Tomorrow will be a "busy" day.
Not only there's RDNA 2 event, looks like we'll see some early reviews of Zen 3 from youtubers.

How am I supposed to get any work done at all?

Thanks Lisa!

 

[Panino Manino]

I don't believe it however.
Makes no sense to allow early reviews of Zen 3 the same day they will showcase RDNA2. What I believe is that they will repeat how they did the last event. They'll just glance over the details of the architecture and go straight to the results, benchmarks, live gameplay with partners and comparisons. Meanwhile what the internet partners will be allowed to do is talk about the details of Zen 3's architecture lifting the NDA.

AMD and Sony are acting the say way this generation, withholding information and releasing it slowing to generate hype.

There bench was also on DDR 2400 memory with pretty crap timings.

There 3800X does 519

My 3800X with PBO Fmax on with the newest Bios at DDR4 3200 with a Ryzen Dram fast profile applied.

Single (5800X) 650 vs (3800X) 541.5 = 16%

That is a 20% boost, not 16%.

 

[Panino Manino]

I was wrong.
No one knows when the NDA ends?

 

[Makaveli]

nov 5th?

 

[inf64]

Launch date most likely.

 

[amrnuke]

Only 1 week folks...

It'll be filled with more than a few leaks I hope, but it'll feel like one of the longest weeks of our lives, I'm sure, with all the non-tech stuff going on as well. For me, going through the sale and purchase of a house, and continued legal wrangling with former job, it'll both fly by and feel like an eternity.

Awesome find Hans!
Here is a another link to sisoftware's Zen3 5800X article: https://www.sisoftware.co.uk/2020/1...-benchmarks-cpu-8-core-16-thread-performance/

Some highlights, confirming what Hans speculated before regarding the AVX units:
"Zen3 improves by a pretty large 35-45% over Zen2 in legacy integer/floating-point benchmarks, a pretty remarkable improvement! Indeed now AMD has a comfortable performance lead over Intel that even 10-cores (+25%) cannot match. "

"With a 64-bit AVX2 integer vectorised workload, Zen3 is 63% faster. "

"While Zen2 with its new 256-bit wide SIMD units was almost 2x faster (+100%) than Zen1/+, Zen 3 still manages to improve anywhere between 25-60%, similar to what we’ve seen in legacy benchmarks. While SIMD workloads were Intel’s strenghts, Zen3 manages to beat even AVX512 10-core SKL-X with its 2x 512-bit wide SIMD units! It seems that there’s nothing stopping Zen3! "

"Ryzen always did well on non-SIMD floating-point algorithms and here it further cements its dominance: it is anywhere between 40 to 290% faster than Zen2 and absolutely demolishes Intel’s CPUs, even the 10-core SKL-X is left in the dust. It just shows that the good-old Skylake core is now pretty much obsolete and the slightly improved versions (e.g. CoffeeLake, CometLake, etc.) are just not enough to catch up with AMD. We really need IceLake/TigerLake here. "

"We previously saw Zen2 40% faster than Zen+ and now Zen3 is a similar 40% faster than Zen2: in effect for the same number of cores (8C/16T), Zen3 is 2x faster than Zen+! Simply astonishing! "

"Executive Summary: Zen3 is ~25-40% faster than Zen2 across all kinds of algorithms. No choice but give it 10/10 overall!

Despite no major architectural changes (except larger 8-core CCX layout and thus unified L3 cache) over Zen2 – Zen3 manages to be quite a bit faster across legacy and heavily vectorised SIMD algorithms, naturally also soundly beating the competition even with AVX512 and more cores (e.g. 10-core SKL-X). Even streaming algorithms (memory-bound) improve over 20%. We certainly did not expect performance to be this good.

In effect, it is like getting 50% more cores – 8-core Zen3 performs like a 12-core Zen2 (e.g. 3900X) – and thus even a 10-core 10900K cannot compete. "



This is a true next generation core, well done AMD!

edit: Crypto tests indicate that Zen3 might be memory BW starved in some cases, a good argument to invest into the higher specced DDR4 memory (4000+)

 

[.vodka]

That kind of performance is absurd.

8 Zen3 cores outperforming 10 Skylake-X cores and their fancy AVX-512 hardware? Well, that's the +50% FP performance piece of the puzzle confirmed.

This is awesome.


I want to see what performance looks like with a nice 4000MHz B-die kit, tight timings, and 1:1 2000MHz fclk!

 

[inf64]

Brutal performance, at least in sisoft tests. I expect that tweaked Zen3 8core (single chiplet) part with IF clock running at 2Ghz and DDR4 @ 4000Mhz will be ultimate gaming and workstation part. The only unknown is overclocking, we haven't heard a beep about it and if it clocks to ~4.4-4.5Ghz all core, then non-gamers will have no choice for productivty workloads but to shell out the $$$ and buy Zen3.

great find to add to this.

They complied it all here for 5600X and 5800X

SiSoftware release early Ryzen 7 5800X and Ryzen 5 5600X 'reviews' - VideoCardz.com

Internal testing results of two Zen3 CPUs: Ryzen 7 5800X and Ryzen 5 5600X have been published by SiSoftware.

Yes, but AMD said that Zen 3 has 20% higher IPC. That is not only 20% higher IPC, so AMD is dirty and insidious liar.

"AMD Ryzen 5 5600X performance

SiSoftware conclusions on Ryzen 5 5600X:

Executive Summary: Zen3 (6-core) is ~15-40% faster than Zen2 across all kinds of algorithms. Thus we’ll give it 9/10."

How is Rocket lake going to compete against 5800X, 5900X and 5950X? I think the 5600X will take the fight against Rocket Lake S

I think Rocket lake may have IPC parity with Zen 3 however they are only limited to 8c/16T and will have no answer for the 12 and 16 core Zen 3 parts.

 

[inf64]

I doubt it will have IPC parity as Zen3 is ~6-7% faster than top Cove (WillowCove). RocketLake will have some version of IceLake with unknown compromises. Where Rocketlake will be better is pure clockspeed since some leaks suggest 5.3Ghz Turbo which is ~13% more than 5800X.

Tiger Lake is the one with IPC Parity with Zen 3(if you extrapolate the data from mobile to desktop), Rocket Lake sits between Tiger Lake and comet lake..

So these aren't considered major architectural changes? Or are they just tweaks? The improvements in load/store and the front end seem like major revisions if you ask me.

• +2.7% Cache Prefetching
• +3.3% Execution Engine
• +1.3% Branch Predictor
• +2.7% Micro-op Cache
• +4.6% Front End
• +4.6% Load/Store

I think it's pretty major - AMD overhauled a lot of architectural components to get those gains. It's a not Contruction_Core-->Zen1 'major' architectural change, but within the Zen family, pretty big.
Plus there are many other changes to the physical implementation to support those architectural changes.

It's a quote from Sisoft website

I think that Zen3 is a true next gen core when compared to Zen2, top to bottom.

Yeah I know it wasn't you that made that statement. I'm just confused that the reviewer didn't even seem to be aware of the many architectural changes that AMD themselves had outlined in their presentation earlier this month.

I mean you don't get a19% IPC increase without significant changes.

 

[Ajay]

Man, Nov 5th can't come soon enough! I want a straight up performance review from AT (and others). If the net average performance increase is 25% higher in ST, then I might be interested in selling my 3900X and buying a 5800X. Might as well since my platform will be EOL once Zen4 comes out (and the net cost too me should be small).

Exactly - they are not just tweaks.

Papermaster has explicitly said that they altered every area of the processor. While the layout of having cores surrounding L3$ is similar, the impression I get is that they've made very big changes to the cores.

SiSoftware obviously haven't done any kind of deep dive. They have no die shots. And it seems like they are just saying, "well, the layout looks the same so it must not be a major architecture change" without even considering what has clearly changed. It's like looking at two pieces of paper and saying, "well, they're the same size, so must not be that much different" when one is a check for $25,000 and the other is a divorce summons.
