They need additional "platform and product validation time", not manufacturing process fine tuning.
Just bugs in the design, then.
While Intel has bagged Nvidia as a marquee customer for its next-generation Xeon Scalable processor, the x86 giant has admitted that a broader rollout of the server chip has been delayed to later this year. Sandra Rivera, Intel's datacenter boss, confirmed the delay of the Xeon processor, code-named Sapphire Rapids, in a …
Think a little further in the future: Intel says Sapphire Rapids will be the clear leading server chip when it comes out – but then AMD's next-gen Epyc will soon land that will even out the race (or overtake the Xeon family).
Intel's saying that, in its view, its time to be the leading server processor supplier again will be a lot shorter than it expected. Which is quite something.

mmmmm AMD already have surpassed Intel on core count and power efficiency in the DC.
Milan vs Ice lake single core performance is roughly on par, with 64 Cores vs 40.
Sapphire Rapids is based on the Alderlake chips which on the desktop only just beats AMD in single threaded performance.
Current leaks of Zen 4 show a minimum (AMD sandbagging) 15% ST improvement and Genoa will be up to 128 cores per socket (96 pretty much confirmed).
Sapphire Rapids = 8 Memory Channels
Genoa = 12 Memory Channels
The only advantage I can see with intel will be in the 4/8 and beyond socket market (needs 4 sockets to compete with AMDs 2 socket)
