The new roadmap covers the fourth-gen EYPC processors. The 96-core Genoa will come on the 5nm process in 2022, while the 128-core Bergamo, also on 5nm, will come to market in 2023. In addition, Bergamo comes with a new type of 'Zen 4c' core optimized for specific use cases, meaning that AMD's Zen 4 chips will come with two types of cores, with the 'c' cores obviously being the smaller variants.

Here's AMD's TLDR for the Zen 4 CPU roadmap:

  • “Genoa” will have up to 96 high-performance “Zen 4” cores, implement the next generation of memory and I/O technologies in DDR5 and PCIe Gen 5 and drive platform capabilities that perfectly balance the Zen 4 core, memory, and I/O to deliver leadership performance
  • “Bergamo” is a high-core count compute engine, customized for cloud native applications that demand high density thread density. Featuring 128 high performance “Zen 4 C” cores
  • "Bergamo” has all the same features as Genoa including, DDR5, PCIe 5, CXL 1.1, same RAS, and the full suite of Infinity Guard security features, and it is socket compatible with Genoa
 
AMD Signs Up Meta in Another Big Win on Server Customers

Bloomberg - Are you a robot?

Meta will use AMD Epyc processors in its data center computers, the two companies said Monday at an event. AMD also unveiled a new version of that chip with extra memory, which Microsoft Corp. will use in an offering from its Azure cloud computing service. The chipmaker also showed off a new graphics chip for artificial intelligence workloads and gave hints about its next generation of processors coming in 2022. The addition of Meta, the world's largest social media company, to AMD's customer list means it now supplies all the top operators of the giant computing networks that run the internet. Winning those major spenders was part of Chief Executive Officer Lisa Su's plan to resurrect AMD and have it reach market share levels it had only briefly flirted with amid years of struggling to keep up with Intel.

While this is for the datacenter and cloud markets, 'tuber Moore's Law is Dead has hypothesized that these Zen4c cores (he had them leaked as Zen4d, d=dense) will form the basis of AMDs big.LITTLLE concept. This might bode well for future AMD consumer processors, with the dense cores having quite a close IPC to the big cores...
The future of ST and MT performance maximization concepts look interesting to me... Even if it may not be a product that I need (no heavy MT workloads), it may be good for ST and MT performance and low load efficiencies are all combined into one product.
 
I've not been following the PC market, but what happened to ~3-4k mobos and CPUs? I thought we'd be getting 4 core CPUs at these prices but the minimum CPU price seems to be around 10k
 
Man were going to be in another golden age of chip dev very soon and I cant wait. We have to just get through this hell that hopefully lasts for only 1 yr more

I hope so, but you remember the Thailand floods ? HDD prices didn't get to normal for four years after the effect of floods had receded. Quality has gone down, and never improved.

Once corporations get used to higher prices, they may not come down easily.

Yeah but 4 years later you telling me that a 7K for a 1tb SSD ain't awesome ? Nothing will stop the progress of technology. And the prices will adjust after time passes. Plus there will be more production supply and investment in the semiconductor industry world wide. Were on the extreme end of a demand supply curve with insanely high demand and relatively low supply. Let supply 2 x over the course of the next two years and you'll see how that changes.

Thailand makes rotating magnetic hard disks. So awesomeness of SSDs is unrelated good fortune from China, Israel and Taiwan.

I would love for your predictions to come true, I feel sad in not seeing the symptoms of recovery yet.

For increasing supply, chip manufacturers have to risk buying TSMC capacity months in advance, by which time demand "may" change drastically. Which is why, at least so far, supply hasn't drastically increased in spite of huge shortage.

Just see AMD laptops, which are objectively better than Intel in many regards. Dell is selling no AMD latitudes and XPSes. HP selling zero elite books with AMD, and one tenth of ProBook/Zbook models compared to Intel ones. Lenovo is selling AMD ThinkPad T and P series on its website, but delivery time is ten times that of Intel counterparts. Amazon has zero business laptops with AMD 5xxx CPUs, after 6 months of release of chips. Basically AMD is not risking increase in laptop chips in spite of clearly superior product.
