AMD Announces a Red October: Zen 3 on October 8, RDNA2 on October 28
AMD CEO Dr Lisa Su on Twitter just announced AMD's next-generation Ryzen processors based on the "Zen 3" microarchitecture, and next-generation Radeon RX graphics cards based on the RDNA2 graphics architecture. AMD is promising a "red" October, with next-generation Ryzen "Zen 3" launch on October 8, and next-generation Radeon RDNA2 launch on October 28. We know for sure that AMD is referring to Ryzen and not EPYC, looking at the Socket AM4 MCM animation being used. The teaser picture for Radeon RDNA2 also hints at a new reference cooling solution with large axial fans.
Update 16:54 UTC: In a separate Tweet, AMD announced the Radeon RX 6000 series graphics cards, based on the "breakthrough" RDNA2 graphics architecture.

This whole idea that AMD lags behind in the quality of its IMC is just misguided. The frequency validations and benching around the DDR4-5000 mark on both single- and dual-CCD Matisse clearly shows that isn't the case. Matisse is competitive with Comet Lake; the issue at the extreme high end is that both platforms have their own quirks and secrets regarding the relationship between stability, secondary voltages and the IMC - so as with IPC, it's hard to put a finger on who exactly is better.
Matisse's weakness is the Infinity Fabric. With IF reliably clocking far lower than the IMC at DDR4-5000 (2500MHz MCLK), there's no point to pursuing high frequency RAM for anything other than validations.
You're taking Matisse's high DRAM latency and attributing that to the memory controller. The memory controller is in the I/O die. It's Infinity Fabric thats holding back DRAM and core-core latency. Though the chiplets aren't going away, if Vermeer can expand the shared resources between 8 cores, we've already seen what that can do to core latency and performance (3300X).
Renoir is merely an iterative uplift on the Matisse IMC design, yet that same design yields far lower latency on a monolithic die and also clocks up to the moon. That latency you're seeing doesn't correlate to the IMC being shitty, champ.
I think times got mixed up, as his tweet was 9.9. at 2AM. VC probably reported it wrong and Frank meant tomorrow as in 9.9. but from US time perspective. So the actual announcement (for the announcement lol) was supposed to be today. And how exactly are you adding to the discussion?
More links would help and adding those Chiplet to Chiplet to skip the IOD Latency would help for Chiplets.
I really wonder why the core complexes lack infinity fabric links since CCX to CCX must also through IOD on Zen2 back to the CCX.
PS: not really happy about these casual references to a political regime that is actually responsible for the deaths of millions of innocent people.
I have better expectations on GPU side, but Nvdia is miles ahead.
And now its time to move on.
Until then, they're prob relying on their cards being faster, + ray tracing, + all the extra nVidia perks to offer a better premium deal for that extra cost. And they have the market share, fan base, and marketing machine in full swing. They won't have much worries even if RDNA2 performance is near.
It's on AMD's hands to give them a complete proper fight now.
some poor engineer is being harassed by the PR guys this very second to make convincing slides for how fast it is
RDNA 2 is expected to be a significant improvement if I take AMD to their words, but announcing 1.5 months after Ampere means they are going to miss the upgrade train and therefore, lost sales to Nvidia. Moreover announcement is 1 part, the second part is when it will be available for sale. By end Oct, they are already in the start of the holiday season. Assuming they take another 2 to 4 weeks for the product to be widely available, they are deep in the holiday season which would cost them more sales.
