AMD announced the new Bergamo product in its fourth-generation EPYC processor family, with up to 128 Zen 4c cores.
According to the latest report from TechPowerUp, the Zen 4c core is not the E-core positioning of Intel’s processor. The Zen 4c core is 35% smaller than Zen 4 but has the same IPC.
As shown above, the AMD Zen 4c core size is 35% smaller than Zen4.
According to AMD’s official PPT, AMD Zen 4c and Zen 4 have basically the same various metrics, the difference being that Zen 4 cores have 3MB of L3 cache per core, while Zen 4c has 2MB.
AMD data shows that Zen 4c has exactly the same IPC (performance at a given frequency) as Zen 4 because it has the exact same front-end, execution stage, load/store components and internal cache hierarchy.
As reported earlier, AMD’s latest Bergamo processor focuses more on “cloud computing at the business level”, supporting up to 128 Zen 4c cores and compatible with x86 ISA instructions, which can relatively meet the needs of deep cloud computing applications. AMD’s President and CEO, Mr. C.F. Su, said that the Bergamo processor, which is focused on “cloud computing,” offers AMD’s largest vCPU computing density to date and provides “best-in-class energy efficiency” and “up to 2.5 percent more power than AMD’s previous EPYC processors. Bergamo processors offer up to 2.7 times the energy efficiency and three times the number of containers compared to AMD’s previous EPYC processors.
Previously, it was announced that AMD’s consumer mobile processors were also available in a “heterogeneous version” with the Zen 4 + Zen 4c combination, but AMD has yet to launch the processor series.
