New rumours have surfaced online regarding the discovery of AMD’s two new CPU families. The new entries include a 5nm Zen 4 powered EPYC lineup and a 7nm Zen 3 powered Athlon APU lineup. These families have been in hiding until now, and we are yet to hear much about them.
AMD EPYC Bergamo CPUs – 5nm Zen 4 & Up To 128 Cores
It’s not like we haven’t heard this name mentioned before, and we have come across some rumours stating that AMD’s EPYC Genoa will be of 128 core, but now those rumours seem to have been overtaken by the latest resident of the rumour hill.
According to sources, AMD’s EPYC Genoa lineup will feature TSMC’s 5nm process-based Zen 4 cores and will have a total of 96 cores. This means that AMD went with 128 cores for the initial tests, but for some reason, it finally settled 96 cores for its final design.
However, rumours are also floating around stating that AMD will launch another Zen 4 based server lineup after Genoa. This lineup will be known as Bergamo. The EPYC Bergamo chips will feature up to 128 cores and will face off against the HBM powered Xeon Sapphire chips.
According to sources, the Genoa and Bergamo chips will utilize the same SP5 socket however, Genoa will be optimized for higher clocks and Bergamo is optimized for higher-throughput workloads.
The latest renders from AMD’s EPYC Genoa chip revealed to us a total of 12 Zen 4 CCDs to reach 96 cores and we can concur that a total of 16 Zen 4 CCDs will be required for Bergamo to hit its 128 core count.
AMD Athlon Monet CPUs – 7nm Zen 4 & Up To 4 Cores
Secondly, let’s talk about another family which recently surfaced online and that’s the entry-level APU lineup. this will be the successor to the AMD Athlon 3000 Mobility APUs which are currently based on the Dali design however its new successor is going to be based on Monet. Speaking of Monet, the base will be utilizing 12nm Zen 3 core architecture & will power the entry-level mobile solutions such as ultra-thin laptops.
In the new lineup, AMD will be utilizing GloFo’s 12nm process node instead of TSMC’s 7nm process. As we know all the Zen 3 chips are based on the TSMC 7nm node so it will be interesting to see the performance of Zen 3 which will be based on some other node instead of TSMC.
