AMD Announces 3rd Generation EPYC 7003 Enterprise Processors

AMD today announced its 3rd generation EPYC (7003 series) enterprise processors, codenamed "Milan." These processors combine up to 64 of the company's latest "Zen 3" CPU cores, with an updated I/O controller die, and promise significant performance uplifts and new security capabilities over the previous generation EPYC 7002 "Rome." The "Zen 3" CPU cores, AMD claims, introduce an IPC uplift of up to 19% over the previous generation, which when combined by generational increases in CPU clock speeds, bring about significant single-threaded performance increases. The processor also comes with large multi-threaded performance gains thanks to a redesigned CCD.

The new "Zen 3" CPU complex die (CCD) comes with a radical redesign in the arrangement of CPU cores, putting all eight CPU cores of the CCD in a single CCX, sharing a large 32 MB L3 cache. This the total amount of L3 cache addressable by a CPU core, and significantly reduces latencies for multi-threaded workloads. The "Milan" multi-chip module has up to eight such CCDs talking to a centralized server I/O controller die (sIOD) over the Infinity Fabric interconnect.
The I/O capabilities of the new sIOD are largely unchanged from the previous gen—128 PCI-Express 4.0 lanes, and 8-channel DDR4 memory—however, AMD has updated the memory controllers to support 6-channel memory interleaving, besides 4-channel and 8-channel. The Security Processor located in the sIOD has also been updated to enable newer forms of secure virtualization, including Secure Nested Paging, a technology that prevents a rogue/compromised hyepervisor from gaining access to the secure memory of a guest VM. AMD also introduced hardware-level hardening against a broad spectrum of control-flow attacks.
AMD's product stack for the EPYC 7003 series includes 64-core, 56-core, 48-core, 32-core, 28-core, 24-core, 16-core, and 8-core models. There are multiple models based on the same core-counts, but different in the arrangement of the cores. A 32-core processor can be made using four maxed out 8-core CCDs, or eight CCDs with 4 cores enabled, each. Here, the latter configuration would squeeze out more performance, as each CPU core competes with other cores on its CCD for more L3 cache. With Intel's next-gen "Ice Lake-SP" Xeon Scalable processor still unreleased, AMD claims an over 2.0x performance lead over the current Xeon Scalable "Cascade Lake-SP" processors.

In the below table, you'll find the individual EPYC 7003 series SKUs, their specifications, and SEP pricing.
The announcement press-release follows.

At a digital event, AMD (NASDAQ: AMD) announced the new AMD EPYC 7003 Series CPUs, which includes the AMD EPYC 7763, the world's highest-performing server processor. The new EPYC 7003 series processors help HPC, cloud and enterprise customers do more, faster, by delivering the best performance of any server CPU with up to 19% more instructions per clock.

"With the launch of our 3rd Gen AMD EPYC processors, we are incredibly excited to deliver the fastest server CPU in the world. These processors extend our data center leadership and help customers solve today's most complex IT challenges, while substantially growing our ecosystem," said Forrest Norrod, senior vice president and general manager, Data Center and Embedded Solutions Business Group. "We not only double the performance over the competition in HPC, cloud and enterprise workloads with our newest server CPUs, but together with the AMD Instinct GPUs, we are breaking the exascale barrier in supercomputing and helping to tackle problems that have previously been beyond humanity's reach."

AMD EPYC Processors, Powering the Modern Data Center
Available immediately, AMD EPYC 7003 Series Processors have up to 64 "Zen 3" cores per processor and introduce new levels of per-core cache memory, while continuing to offer the PCIe 4 connectivity and class-leading memory bandwidth that defined the EPYC 7002 series CPUs. 3rd Gen AMD EPYC processors also include modern security features through AMD Infinity Guard, supporting a new feature called Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP). SEV-SNP expands the existing SEV features on EPYC processors, adding strong memory integrity protection capabilities to help prevent malicious hypervisor-based attacks by creating an isolated execution environment. You can read more about new 3rd Gen AMD EPYC features here.

All these features and capabilities combine to help drive faster time to results and improve business outcomes for HPC, cloud and enterprise customers.
  • For HPC customers that demand the most throughput computing capabilities to do more simulations in a given time period, or use bigger data sets or more complex models, AMD EPYC 7003 Series processors enable faster time to discovery with more I/O and memory throughput, and powerful "Zen 3" cores that deliver up to twice the performance for HPC workloads compared to the competition.
  • For cloud providers who need compute density and security capabilities, AMD EPYC 7003 Series processors offer the highest core density, advanced security features and up to twice the integer performance compared to the competition.
  • For the enterprise, where performance and time to value are critical to support the new "work from anywhere" environment, AMD EPYC 7003 Series processors help improve efficiency, and deliver value and performance. The new processors increase transactional database processing by up to 19%9, improve Hadoop big data analytic sorts by up to 60% with 61% better price to performance than the competition, and offer superior performance for flexible Hyperconverged Infrastructure - all of which help CIOs turn data into actionable insights faster.

Very interesting lineup.

There's the cheap 7453 at $1500ish for example, probably the most cores per $$. Might be the best at compute-heavy situations, but the lesser L3 cache might hamper it (or might not! Only benchmarks will tell...)

Interesting and diverse lineup for sure.
The 7453 seems to be where all the bad bins are going, the CCDs don't even seem to have fully enabled caches (figures, if there's a minor defect you may not be able to use the full 32 MiB) as it's 4 CCDs for a grand total of 64 MiB of L3 - 16 for each with half disabled.

Funfact: They also made the 72F3 which consists of 8 CCDs with one (1) core enabled each (!), but a full 32 MiB of L3 for each of these cores. Madness.
Also, $900 for the 7313P sounds like a great bargain, you get 16 cores, 128 PCIe lanes and 8 memory channels out of all that for when 24 PCIe lanes and 2 memory channels just won't do.

It's an interesting outlier in other ways too as it has 4 x 4 + 4 x 3 cores active, or some other weird configuration. Nevermind, it's probably 4 x 7, but still the only one in which the number is not a multiple of 8.

I do love the AMD CPUs... These server CPUs are just pure awesome....

Some speculation in other forums suggests that the "F" processors are for those stupid "per-core licensing" software, like Oracle Databases or IBM's DB2 software.

By focusing on highest amounts of cache + lowest numbers of cores, the "F" processors give the most performance with fewest cores. A weird situation for the stupid licensing models of Oracle and IBM. Its a niche, a stupid niche, but a real niche.

Are these going to be DDR5 platforms?

dont whant to set it"'
@voltage Drop in compatible * ; *bios update required; on the premise that the mb can electrically support it , two cents from a quick look at some slides.
