AMD 3G General EPYC Milan CPU specs and benchmark leaked out, up to 64 cores and 280 W TDP

AMD’s next and third-generation EPYC Milan CPU family Q1 is aiming to launch in 2021, with Intel launching its Ice Lake Xion CPU at the same time. Both lineups have seen a fair share of their leaks but today we have a bucket full of information surrounding the specifications and the influence number of the 3rd General EPYC Milan CPU by Twitter Fellows, ExecutableFix.

AMD’s 3rd Generation Milan Server CPU Details, EPYC 7763, 7713, 75F3, 74F3, 7413 and 7313 – up to 64 cores, 280W TDP and 4.0 GHz boost clocks

The details include specifications for six different EPYC Milan chips, featuring all new Zen 3 core architectures. We’ve already seen the AMD EPYC 7763 and the EPYC 7713 CPU leaked, but only the initial ES clock lists. The latest leaks will also shed light on the final clock speed and the TDP that we can expect from these chips.

AMD EPYC Milan 64 Core CPU SQ

Starting with the AMD EPYC 7763, the chip will become one of the fastest Milan SQs in terms of mains density and clock speed. For a combined 288 MB cache the CPU will provide 64 cores, 128 threads, 256 MB L3 cache and 32 MB L2 cache. Cash also brings a big change to the EPYC family with Milan’s Zen3 cores, now accessing a larger pool of L3 caches than 2G General ROM based offerings. In terms of clock speed, the chip will offer a 2.45 GHz base and 3.5 GHz boost watch with a TDP of 280W.

AMD EPYC 7763:
– 64 cores, 2.45GHz base, 3.5GHz boost, 280W TDP

AMD EPYC 7713:
– 64 cores, 2.0GHz base, 3.7GHz boost, 225W TDP

There is also the EPYC 7713 which offers the same core configuration but gives a base clock of 2.00 GHz and a boost clock of 3.70 GHz. Boost is the highest ever offered by any AMD 64 core EPYC. It seems that the base clock is the primary determinant of the TDP which was also in the previous pay generation EPYC CPU. In case of EPYC 7713 TDP will be set to 225W.

AMD will finish production of Radian RX 6900 XT, RX 6800 XT, RX 6800 reference models, focusing on custom AIB variants [Update]

AMD EPYC Milan 32 Core CPU SQ

The 32 core SQ includes the AMD EPYC 75F3 and possibly the 74F3 although the latter may use a different core count (24 cores / 48 threads). EPYC 75F3 is the only confirmed SKU of 32 cores and 64 threads. The chip comes with a base clock of 2.95 GHz and a boost clock of G0 GHz, which is the highest of any EPYC server CPU released to date.

Also heard of a 74F3, but no specs yet. Should there be 24 cores? https://t.co/oWxWWtGV2e

The CPU will also have 256 MB L3 cache which means it will come with 8 Zen3 core complex dyes or CCDs with full dye configuration. TDP will be fixed at 280 W for this SQ.

AMD EPYC Milan 24 Core and Lower CPU SQ

Finally, we have two confirmed and four unconfirmed SQs below the 32 core segment. First, we have the EPYC 7413 with a 24 core and 48 thread CPU with 123 MB L3 cache (16 MB L2), 2.65 GHz base and 3.60 GHz boost clock. The CPU will have a TDP of 180W.

You know, here you go

EPYC 7413, 24 cores, 2.65GHz base, 3.6GHz boost, 128MB L3, 180W TDP

EPYC 7313 (P), 16 cores, 3GHz base, 3.7GHz boost, 128MB L3, 155W TDP

+ I’ve heard of 74F3, 72F3, 7443 and 7663 https://t.co/nalsn5xECX

The EPYC7313 is the second confirmed chip with 16 cores and 32 threads. The CPU will have 128 MB L3 cache, so two CCDs out of the four CCXs that die each are partially disabled. The CPU will be given a base clock of 3.00 GHz and a boost clock of 3.70 GHz with a TDP of 155W. Other SQs include 72F3, 7443 and 7663 although details of those SQs are not yet available.

AMD EPYC Milan 3G General Server CPU Lineup (Initial):

AMD EPYC Milan 64 Core CPU vs EPYC ROM 64 Core CPU Benchmark

Multiple performance tests for 64 core AMD EPYC Milan CPU were also conducted. For IPC tests, both chips were locked at 2.4 GHz, and the Milan CPU scored an average of 14% IPC lift due to its fast Zen3 course. With Boost enabled, the EPYC Milan CPU ran up to 3.7 GHz (13 77113) and achieved a 27% single-core performance improvement compared to the 280W 64-core Jaguarite based on the fully unlocked chip Zen 2 cores.

In multi-threaded tests, the AMD EPYC 7713 scored 10% performance improvement with Boost Enabled. These are definitely some impressive figures but we expect them to get even better and faster by the time AMD launches its 3rd Gen EPYC platform.

A more interesting benchmark is the Cinebench R23 run in which EPYC 7713 scored 87878 points in multi-core and 1215 points in single-core tests. For comparison alone, the CPU is 18% faster than the Raizen Threadripper 3990X and 76% faster than the Cascade Lake-SP Xion 8280L Platinum chip in multi-core tests.

Compared to the same CPU in single-core tests, the EPYC7713 is due to its clockwise 2.9 GHz base and 4.3 GHz boost but unlike the Intel Xion chip, the EPYC Milan CPU is 18-20% faster. Now Cascade Lake-SP is definitely older and will soon be replaced by Ice Lake-SP which will offer cc cores, but we have seen from previous benchmarks that Ice Lake-SP rarely beats the Cascade Lake-SP lineup with 18% IPC. The uplift that Sunny Cove Coro has to offer is not enough to face Milan.

Also, 10nm + clocks will not look great compared to 14nm + nodes. Clocks and functionality are a whole different thing and AMD now seems to lack even in Intel in terms of cores. Now servers up to 64 cores offer two full pay generations of CPUs. That sounds awful for Intel’s IceLake-SP line of server chips but Intel seems to be betting all on AAVX-512 workcodes because right now they have the only edge against AMD’s EPYC processors.
