AMD announces 32-core eight-RAM-channel Naples family

AMD announces 32-core eight-RAM-channel Naples family

AMD has officially announced its long-rumoured Naples system-on-chip (SoC) server processors, based on the Zen architecture and scaling to 32 cores and 64 threads per socket with two sockets per system.

AMD has formally confirmed its Naples server-oriented Zen architecture processor, designed for those with need of wider threading support than the consumer-oriented Ryzen family, will offer 32 cores and 64 threads with support for up to two processors per board.

Details of the Zen-based Naples chips have been leaking out for some considerable time, but AMD has now officially gone on the record: Naples will launch later this year with the top-end model offering 32 physical processing cores with support for 64 simultaneous threads. As per the previous rumours, Naples isn't a simple processor but a system-on-chip (SoC) design with on-board support for 64 lanes of PCI Express 3.0 connectivity, AMD's Infinity Fabric high-performance coherent interconnect for dual-processor implementations, and eight-channel memory - the latter allowing for up to 32 DDR4 DIMMs in a single server across 16 memory channels and supporting a theoretical maximum memory capacity of 4TB.

'Today marks the first major milestone in AMD re-asserting its position as an innovator in the datacentre and returning choice to customers in high-performance server CPUs,' crowed AMD's Forrest Norrod at the unveiling. ''Naples' represents a completely new approach to supporting the massive processing requirements of the modern datacentre. This groundbreaking system-on-chip delivers the unique high-performance features required to address highly virtualised environments, massive data sets and new, emerging workloads.'

AMD has said that it will launch Naples formally in the second half of this year, though has not yet providing pricing information; neither has the company announced partner companies which are planning to launch server products based around Naples, a market currently dominated by Intel's Xeon family of processors. More information is available on AMD's announcement page, while the announcement presentation for the chips is reproduced below.

Should that be "now"?

Knowing next the nothing about server products how does, on the surface, Naples compare with Xeon?

Yes. Yes, it should.

We won't know until somebody gets to test 'em properly. Naturally, AMD says Naples is better - but it's going to run into the issue of compilers being heavily optimised for Intel microarchitectures, the lack of greater-than-two-socket support (though to be fair this is somewhat mitigated by each socket having so many cores and memory channels), and convincing companies to actually build Naples servers people can buy. It looks promising, though, and if Naples undercuts Xeon like Ryzen undercuts Core then it has a fighting chance of succeeding.

Would be wise to wait for the benchmarks on this one, though Ryzen has a lot of cores for example, it only supports AVX-128 instructions while Intel is at AVX-512.

Sorry when i said how does, on the surface, Naples compare with Xeon i should have been more specific, i should have said how does the core count, amount of I/O bandwidth (PCI-e lanes) and supported RAM compare. :)

Xeon tops out at 24 cores vs the 32 of Naples, 40 pci-e lanes vs 64 per socket (AMD says 128, but 64 of them vanish in multi socket config), quad channel vs octo channel and the 24 core chip costs over $8k vs most likely less for the 32 core chip.

So on first glance Xeon gets beaten to a bloody pulp.

But of course nothing is that simple, Xeons can go beyond two sockets, software has been optimized for Intel due to AMD having been gone from the scene for years, so Intel may still have an advantage due to that, plus there are specialized products that will make minced meat out of either one (Xeon and Naples are just the fastest all purpose chips), depending on workload you may have consider stuff like Xeon Phi, Nvidia Tesla or the upcoming Radeon Instinct and potential compatibility issues / bottlenecks etc...

I think AMD are onto the right track, technically speaking, but that won't be enough.

Intel will own a few compute-heavy scenarios no doubt, but there's more noise there in the form of non-x86 there too and the biggest chunk of the market is general purpose virtual compute. Scaling beyond two sockets there is largely irrelevant, where environments are almost overwhelmingly memory constrained. Even scaling to more than one socket is of questionable value when you're licensing by the socket, and probably aren't even touching the sides with a single 20+ core CPU.

In the end, mainstream success or failure is more down to partnerships than the competency of the platform...

Then there's the new totally-not-E7-any-more-guys Xeon 'Gold' and 'Platinum' bunch-o-cores chips coming soon to drop into LGA3647.
