AMD Ryzen 2018-2020 Roadmap leaked: Castle Peak, Matisse, Picasso, Vermeer and Renoir

AMD has recently held a special event for retailers and distributors. A new roadmap has been shown there, revealing the codenames of upcoming Zen2 and Zen3 processors.

It appears that 2nd Generation Ryzen Threadripper (Zen+) will be succeeded next year by Castle Peak architecture, based on Zen2. In 2020 AMD is set to unveil refined Zen2 architecture, which is currently known at Zen3 (not to be mistaken Zen2+). A cryptic codenamed of NG HEDT is currently listed for Threadripper 3rd Gen.

When it comes to ‘mainstream’ Ryzen, AMD is likely to adopt a new naming schema, with each generation named after a known painter.

While Matisse and Picasso codenames were already leaked a few months ago, Vermeer and Renoir are new.

That said, Ryzen 2000, codenamed Pinnacle Ridge, will be succeeded by Matisse next year (based on Zen2) and replaced by Vermeer (based on Zen3) in 2020.

Raven Ridge APUs are to be succeeded by Picasso and Renoir, based on Zen2 and Zen3 respectively.


A confirmation of the previous leak has also been provided. Pinnacle Ridge lineup is to feature only four SKUs, there is no Ryzen 7 2800X. A simplified Ryzen 2000 desktop series lineup should provide a simpler choice for customers at launch. More SKUs will likely be unveiled at a later date.

I believe that this is due to motherboards rather than the IMC this time. Raven Ridge embedded is rated for 3200MHz JEDEC.

Not all 300 series mobos have robust enough traces to support high memory clocks, so 2933 is the lowest common denominator.
my $89 ASRock AB350 Pro 4 is running 3200 cl14......

Being B350 doesn't mean they cheapened out on the memory traces.

That spec needs to run all the way down to the A320 crapola.
The Gigabyte GA-A320MA-M.2, one of the cheapest boards available, supports DDR4-3200 perfectly.

I've discussed this matter in another thread, but when it comes to JEDEC support, I think they are aiming for what they feel will be the fastest-available 1.2v DIMMs for the desktop market. AMD supports DDR4-3200 with their embedded/mobile Raven Ridge chips (and by extension, AM4 desktop Raven Ridge chips) to accommodate DDR4-3200 SODIMMs which do exist @ 1.2v . Eventually we may even find SODIMMs that follow the JEDEC DDR4-3200 CAS/CL 20 spec @ 1.2v .

For now I find it highly unlikely that we will ever see JEDEC DDR4-3200 DIMMs. Functionally, Pinnacle Ridge/Matisse/Vermeer will have the same (or better) support for fast memory speeds as Raven Ridge/Picasso/Renoir. They're just not going to label them as supporting a standard that will not exist on desktops.

I wonder why AMD doesn't just bake in a GPU into all of it's processors like intel does? Hmmm.. I'd like to see a 1700 or 1800 (apu) series. Some people don't need a graphics card.

Pinnacle will have far better memory support than Raven.

I believe that this is due to motherboards
Even the lowest quality (i.e 4-layer PCB) motherboards can handle >= 3600MHz with ease, when properly designed.
For example MSI B350 Tomahawk is one of the best boards memory frequency wise, despite being a 4-layer design.

Also mainstream Z370 boards generally have no issues in reaching >= 4000MHz either.

DRAM related issues on Ryzen were never related to the motherboards themselves, regardless of some statements claiming otherwise.

We're only going to see higher frequencies if the actual memory IP has improved.

Then it's odd that the 400 series motherboards are advertised as potentially having better memory overclocking.

Anyway, I don't expect any properly built X370/B350 boards to show any difference, but the official number of 2933 on Raven Ridge when the embedded variant claims 3200 tells me AMD isn't confident in a few bad apples in the 300 series.

I am running 3600 on one of my Taichi boards (X370)
