I thought AMD had already brought chiplets to data center CPUs a long time ago [1], [2] and that is why they are leading currently, now that they have multiple generations of chiplet data center CPUs out?

I wonder if they'll call it "glued-together". <a href="https://www.pcgamer.com/intel-slide-criticizes-amd-for-using-glued-together-dies-in-epyc-processors/" rel="nofollow">https://www.pcgamer.com/intel-slide-criticizes-amd-for-using...</a><p>The 4 die SoC does look an awful lot like 1st gen EPYC.
I find it interesting that the dies aren’t completely identical like Zen chiplets are. If I am reading the diagram correctly, it looks like the tiles diagonal from each other are the same. Kind of neat that they’ll have left-hand and right-hand wafers.
> Intel Corp.’s fourth-generation Xeon processor, codenamed Sapphire Rapids<p>If you are just as confused as I am at "fourth generation" when Xeon has been around for decades, they mean "fourth-generation Xeon Scalable Processor (SP)". Skylake-SP, Cascade Lake-SP, Ice Lake-SP were the previous generations. Where Xeon processors previously used E3/E5/E7 designations for 1/2/4+ socket capabilities, SP CPUs use metallic prefixes: Bronze representing basic processors, Silver low power, Gold adding different options for advanced interconnects and integrated accelerators, and Platinum offering the widest range of capabilities.
Intel is in the cusp of getting taking out. Architectures and process technologies are both multiple generations behind. AMD has 10x its server share. If the trend sustains for one more generation the majority of the market will go to AMD.
