AMD Zen server chip could have 32 cores, 64MB cache, 128 PCIE Lanes

Although AMD and Intel’s next-generation CPUs aren’t expected to arrive until 2017, that doesn’t mean we won’t be talking about them a lot in the interim, and the latest rumor to emerge suggests that the Zen server processor is a monster. Along with claims that it has as many as 32 cores, we’re now being told that its shared last-level cache is as high as 64MB.

Of course server chips are usually quite powerful as their jobs are much tougher than your average gaming PC’s. That said, do take these rumors with a pinch of salt, as Fudzilla‘s sources are far from confirmed.

With that caveat out of the way though, we can enjoy the speculation for what it is. Supposedly this Zen chip, code-named Naples, will sport those 32 cores, giving it support for 64 threads if needed. It can be twinned with DDR4 memory we’re told and with up to 128 lanes for third-generation PCIExpress, there should be no shortage of opportunities for add-in cards.

Perhaps of the greatest impact, if true, is that the chip is said to have 512kb of cache for each core and that each “cluster” has as much as 8MB of L3 cache, giving the chip a total of 64MB of cache.

Other specifications peg the server hardware as able to support up to 32 SATA or NVME drives, with an integrated network controller allowing for up to 16 x 10 Gigabit Ethernet connections.

There will be variations on the chip though, with the 32-core version acting as the flagship server processor and 16-core, eight-core, quad-core and dual-core versions of the enterprise-focused hardware released around the same time. There is a suggestion that some may show up just before the new year, but most seem to think that a CES debut for Zen is the most likely time for them to make their appearance.

This goes doubly so when you consider that AMD’s CEO, Lisa Su, previously told Fudzilla that the server chips would appear after the desktop versions, which are currently expected to make their appearance at CES 2017 in January.
