AMD Zen 3 Reveal Liveblog

This is our liveblog for AMD’s Zen 3 reveal. Join us as we analyze the reveal of AMD’s upcoming Zen 3 CPUs in real time. The presentation starts at 12 PM EST, but if you get here early, then feel free to read on to get a summary of our prior Zen 3 coverage.

Our first exclusive about Zen 3 was published in April. In this article, we detailed Zen 3’s primary innovations: the 8 core CCX, a unified L3 cache, and 10-15% increased IPC. AMD actually leaked those first two things in a presentation that was uploaded to YouTube by accident, but we provided never before seen details on IPC and the size of the L3 cache, which many theorized would be enlarged but according to our info the cache is still 32 MB. Had AMD not leaked this info themselves, this very well could have been the first time we ever heard about the 8 core CCX.

We published a followup in July that elaborated further on the IPC increase, and also provided details on clock speeds and the schedule Zen 3 processors were on. We reported that Zen 3’s IPC improvement was almost entirely from integer operations; this improvement to integer performance is about 15% according to our info. We also said that we expected a modest clock speed gain on single threaded to lowly threaded workloads. Based on internal roadmaps and reports from our sources, we expected Zen 3 chiplet production to begin in September, leaving little time between production and product launch.

Our second exclusive was slightly controversial because we expected the increase to floating point performance to be very low, nowhere near the theorized 50% improvement. Thankfully, we could actually determine whether or not there will be a significant improvement to floating point performance thanks to publicly available details on the upcoming Anvil supercomputer which uses Milan CPUs based on Zen 3. By taking the known performance and core count of the supercomputer, we determined that if there was a significant floating point improvement, the CPUs would be running at an extremely low frequency, far too low to make sense. Assuming that there would be no floating point improvement, clock speeds would be similar to Rome’s, which is what we expect.

Finally, we recently reported on a leaked benchmark which showed the 5800X beating the 10900K in Ashes of the Singularity by 16%. The victory on the part of AMD wasn’t shocking, but what was surprising was the name of the CPU, the 5800X. This is a strong indication that AMD is skipping the 4000 series name for Zen 3. This probably happening because of the Renoir based 4000 series APUs. AMD doesn’t want there to be further naming confusion with the APUs (Ryzen 3000 CPUs were Zen but Ryzen 3000 APUs were Zen+, for instance) and if AMD calls the upcoming Zen 3 CPUs Ryzen 4000, people might assume they’re only as powerful as the Zen 2 based Renoir chips. So, it seems we are looking forward to the 5000 series today, not the 4000 series.

And that does it for our history of Zen 3 coverage. AMD’s presentation should be starting soon if you’ve made it this far.

3080 gets 76fps in GoW5 (on a 9900K) and Big Navi gets 73fps on a 5000-series AMD cpu. BL3 3080 is 69 vs Big Navi's 61. 2080 Super is 40 and 2080 Ti is 50. This certainly helps put to bed the fears that it would only compete against the 3070. It also means it won't beat the 3080 by any significant margin either.

Thank you all for watching, and sorry that we didn't have any images, we wanted to use the back end but it didn't work for some reason. We'll fix that for the next live blog on October 28th. Catch you later guys.

Matthew Connatser

So, my thoughts: surprising claimed IPC improvement, unsurprising performance claim. Not that AMD's claim was bad, it was just in line with my expectations. The unified cache and 8 core CCX does wonders for gaming. But we'll have to verify these claims in our own review.

Matthew Connatser
October 8, 2020

Well that was fairly low key, partly thanks to the lack of an audience.

Matthew Connatser

Gaming is close however.

Matthew Connatser

26% gaming performance improvement on average. BF5 is only 5% btw.

Donny Stanley
October 8, 2020
12:18

Far Cry New Dawn at 22%.. that's what I wanted to see!

Matthew Connatser
October 8, 2020

But we will see if this all stands in the reviews.

Kirk Johnson
October 8, 2020
12:18

50% LOL is the best FPS improvement shown.

Matthew Connatser
October 8, 2020
12:18

CSGO up by almost 50%, which also saw a large increase with Zen 2.

Matthew Connatser
October 8, 2020

packaging layout appears largely the same as Matisse.

Matthew Connatser
October 8, 2020
12:16

According to our info, the base clock is actually down 100 MHz, which is weird.

Kirk Johnson

12:14

Zen 3 24% more efficient than Zen 2.

Matthew Connatser
October 8, 2020
12:14

Other than the higher than expected IPC bump, none of this is too surprising.

Matthew Connatser
October 8, 2020

"Effectively twice the L3 cache"

Matthew Connatser
October 8, 2020
12:13

Papermaster discusses how important the new 32 MB cache is.

Matthew Connatser
October 8, 2020
12:13

Well, massive for CPUs, 19% performance gain isn't all that great in the grand scheme of things.

Matthew Connatser
October 8, 2020
12:13

I'm curious what benchmarks AMD ran to come up with 19%, that is massive.

Matthew Connatser
October 8, 2020
12:12

"Clear desktop performance leader"

Donny Stanley
October 8, 2020
12:12

But.. how many TFLOPS? 😛

Matthew Connatser
October 8, 2020
12:12

Our expectation was 15% claimed IPC uplift in integer, wonder if AMD is doing anything with that figure?

Kirk Johnson
October 8, 2020
12:11

Direct Access L3 Cache for every core.

19% IPC Uplift

Matthew Connatser
October 8, 2020
12:11

Wow, 19% claimed IPC uplift.

Matthew Connatser
October 8, 2020
12:11

Zen 3's takeaways are more vague than Zen 2's, strange.

Donny Stanley

"same 7nm node" So, not 7N+ or 7NP?

Kirk Johnson

Su reiterates how Ryzen is designed to be the best desktop CPU ever.

Matthew Connatser
October 8, 2020

This panning shot of AMD powered products does give you the sense that AMD is bigger than they seem.

Donny Stanley
October 8, 2020

Lisa Su is delivering this speech like its in front of a live in-person audience. A bit jarring.

Kirk Johnson

Using the pandemic to sell CPUs, very classy.

Matthew Connatser
October 8, 2020

Lisa Su now speaking.

Matthew Connatser
October 8, 2020
12:04

AMD is very good at hyping things, but once they finally come to market people usually settle down. Ryzen and Zen overall are still good of course.

Matthew Connatser
October 8, 2020
12:03

2017 was a very exciting year, there was alot of hype for a CPU that wasn't terribly competitive across the board.

Matthew Connatser
October 8, 2020
12:02

Okay so here's a highlight reel.

Kirk Johnson
October 8, 2020
12:01

130,008 and stream just started with a 1:30 countdown.

Matthew Connatser
October 8, 2020
12:01

Okay it is about to start in a minute and a half... with this very odd graphic.

Matthew Connatser
October 8, 2020
12:00

AMD seems to be running a bit late, stream should have started a little bit ago.

Matthew Connatser
October 8, 2020
11:58

1 minute to go.

Matthew Connatser
October 8, 2020
11:55

Videocardz says the stream was prerecorded, not too shocking since AMD's not presenting to a live audience. Or, at least, that was my expectation given large audiences are fairly lethal in this year.

By the way I don't believe AMD ever sent us the spec sheet the rest of the press got, we had to rely on one of our sources to fill us in.

Kirk Johnson
October 8, 2020
11:50

66,129 people waiting in the livestream. Certainly a huge turnout for what amounts to a confirmation of specs we practically already know.

Kirk Johnson
October 8, 2020

We've already got some refreshed/updated X570/B550 mobos being announced by motherboard makers, such as the ROG Dark Hero.

Last time we tried doing a live blog it actually crashed the website due to heavy traffic but since we've not only moved to a new host but also trimmed down the website. Hopefully this makes the live blog work much smoother than before, and so far everything seems to be working okay.

Matthew Connatser

Hey everyone, this is the live blog for our Zen 3 live coverage. Show starts in about 15 minutes.
