I don't think that Milan is at all uncompetitive compared to Sapphire Rapids. In Compute alone both platforms are still very similar, which has also been noted by many reviewers. The Corecount is comparable and power efficiency is similar or even better on Milan.
Many people don't care about DDR5 and PCIe Gen5 or Intels fancy Accelerators. They want simple aircooled servers with as many Cores as possible and good power efficiency. And that is when you look at SKUs below 300W where Sapphire rapids has a significant corecount and clockspeed deficit. In this range, SR is loosing the MT CPU performance battle vs Milan, not even winning the per thread performance decisively because of clockspeed.
And as for the obviously better Genoa Products, those are not actually faster at the same pricepoint and not much more efficient. At the same TDP and pricepoint one can get more Zen3 Cores than Zen4, which performs just as good in many compute workloads while being cheaper.
Many Datacenters don't need the higher bandwidth of DDR5 and PCIeGen5 that Genoa offers. Also i wouldn't underestimate how many Customer still prefer standard form factors for server motherboards. This is not possible with 12CH DDR5 and such huge sockets, which is why Epyc Siena has been welcomed by so many.
Wonder if this reflects difficulties producing enough Zen 4 chips (e.g. getting enough 5nm wafers from TSMC), or that the larger platform able to handle 12 CCDs makes it hard to offer it and servers based on it cheaply, or overall market conditions tending to favor cheaper chips, or something different or a mix.
The change in plans does suggest *something* was different from prior expectations.
I don't think Zen 4 EPYC 9004 (Genoa) comes into it since it's in a completely different league in terms of performance and platform cost. As stated in the last sentence of the article, the comparison would be EPYC 8004 (Siena), made with Zen 4c.
Maybe cloud operators are gobbling up all of the Zen 4c supply in Bergamo chips, so AMD is unable to deliver Siena in quantities they had planned?
AMD's EPYC 7003 'Milan' processors have received an extended lifecycle, ensuring availability until 2026. This announcement comes with the introduction of six new SKUs (Stock Keeping Units) within the EPYC 7003 series. These SKUs are designed to meet the growing demand for high-performance computing solutions across various industries. This move reflects AMD's commitment to providing long-term support and flexibility to its customers, especially in data center and enterprise environments. Just as AMD extends the lifecycle of its products, services like CV writing in Oman https://cvmakerdubai.ae/cv-writing-oman can provide long-term support for professionals, helping them achieve their career goals with well-crafted resumes that stand the test of time.
