Intel’s Ice Lake Xeon comes out swinging at AMD’s Epyc Milan

rack mounted muscle —

Chipzilla’s sleek server processors raise more cores, more RAM, more aspects.

Thirty-six individual models of Ice Lake Xeon Scalable processor launch today, with immediate retail availability expected from major system vendors, including Supermicro, HPE, and Dell.

Construct bigger / Thirty-six particular person devices of Ice Lake Xeon Scalable processor originate on the present time, with rapid retail availability expected from valuable machine distributors, including Supermicro, HPE, and Dell.

Intel launched a sleek batch of third-generation Xeon server processors on the present time. Considerably, these are Ice Lake processors—that design Intel’s 10 nm direction of, not the an increasing number of out of date 14 nm direction of that the huge majority of Intel’s lineup has been caught on for many years now.

At the moment time’s preference entails a staggering 36 separate SKUs, starting from 8-core Xeon Silver 4309Y your entire approach up to 40-core Xeon Platinum 8380.

Gen-on-gen efficiency enchancment

There’ll not be any assign a question to that on the present time’s Ice Lake Xeons are a essential, badly wished enchancment to Intel’s server lineup. Similarly to Intel’s Ice Lake notebook ingredients, clock speeds are down from the older 14 nm ingredients—nonetheless IPC is up more than ample to compensate, and unlike the Ice Lake notebook ingredients, these Xeons continuously boast more cores than the final generations construct, pretty than fewer.

We haven’t had the probability to switch fingers-on with on the present time’s Ice Lake Xeons ourselves, nonetheless Anandtech did. Evaluating on the present time’s 40-core Xeon 8380 to 2019’s 28-core Xeon 8280, single-threaded exams continuously advance out 3 to 15 p.c in prefer of the more recent generation—and multi-threaded exams prefer the more recent phase by a whopping 54 to 65 p.c.

This, pointless to claim, ignores the elephant within the room—Intel’s precise rivals, which comes within the assign of AMD Epyc processors. As immense an enchancment as Xeon 8380 is, or not it’s indifferent not ample to have interaction up to Epyc Milan, or even the older Epyc Rome.

Epyc 7662, 75F3, 7742, 7713, and 7763 all beat the 8380 handily in both integer and floating level multi-threaded metrics. Epyc 75F3 and 7763 beat it in single-threaded metrics as successfully, with 75F3 doing so by a fairly broad margin.

Characteristic and effectivity enhancements

With the sleek Ice Lake Xeons indifferent lagging deal slack AMD (and Ampere, an Arm-based mostly entirely server processor), Intel’s marketing technique basically specializes in Intel-most attention-grabbing aspects and explicit exhaust cases pretty than sheer muscle.

Functions admire the AVX-512 prolonged instruction build, Instrument Guard Extensions (SGX), and Optane DC Continual Memory are most attention-grabbing learned on Intel systems—they usually can represent valuable efficiency enhancements or even manufacture-or-damage requirements for workloads particularly tailored to them.

The sleek generation of Xeon brings improve for PCIe 4, 4TiB of DRAM (up from 1TiB), a sleek 512GiB SGX Enclave—and a decrease label. The 40-core Xeon 8380 is “most attention-grabbing” $8,100, when put next to the 28-core Xeon 8280 at $10,100.

Xeon Platinum 8380 does quit one characteristic as when put next to 8280—fewer particular person sockets. You can originate an 8380 machine in either single-socket or twin-socket variants, whereas 8280 supported 4- and eight-socket platforms as successfully.

Even supposing 8380’s overall TDP is up—270 W, when put next to 8280’s 205 W—the sleek phase is indifferent more efficient overall, at 6.75 W/core to 8280’s 7.3 W/core. The amplify in effectivity becomes noteworthy more evident when evaluating SPECint or SPECfp scores per watt.


Between the puny availability of first-generation Ice Lake notebook CPUs and puny availability of earlier batches of third-generation Xeon Scalable, we positively had availability considerations about this most modern batch of Ice Lake Xeons.

We spoke to Supermicro Senior VP Vik Malyala about the sleek systems, and he informed us that Supermicro will likely be ready to ship sleek Ice Lake-based mostly entirely servers in ample quantity to fulfill assign a question to.

Commercial analysts at Trendforce agree, claiming that sleek Ice Lake CPUs will likely fable for 40 p.c of Intel’s total CPU shipments within the fourth quarter of 2021. Trendforce also notes that despite AMD’s commanding efficiency and below-load vitality effectivity advantages, Intel retains a 92 p.c market allotment within the x86 server segment.
