AMD Zen 6 SMT Proves Very Advantageous Even For 256 Core EPYC 9996
With the now-shipping AMD EPYC 9006 "Venice" SP7 server processors sporting up to 256 Zen 6(C) cores per socket, or 512 cores in a 2P configuration,…
Why am I seeing this Ranked on source trust — Phoronix
It ranks mainly on source trust: Phoronix is the most reliable outlet we track on this subject, and is the only one on the story so far.
Single-sourced. No second organisation has confirmed it yet.
Link-outLink-out, because only one organisation carries it and no first-party source is on it. Link-out means we point at the publisher and say nothing of our own.
| Factor | Weight | Score | Contribution | Where it came from |
|---|---|---|---|---|
| Corroboration | 0.35 | 0.39 | +0.135 27% | 1 independent org on the story. Tier-3 aggregators never corroborate — they can show something is circulating, never that it is true. |
| Source trustleads | 0.25 | 0.80 | +0.200 40% | Phoronix is the highest-trust source on this story. Trust is taken from the best source, not averaged. |
| Pickup rate | 0.20 | 0.00 | +0.000 0% | One counted organisation, so there is no spread to measure — nothing has picked this up to set a rate. |
| Freshness | 0.20 | 0.81 | +0.161 32% | Halves every 10 hours from the newest item on the story. This is the only factor that rewards a story for nothing more than being recent. |
Corroboration counts distinct organisations, once each, and only from tiers 1 and 2. Freshness halves every 10 hours, so this ranking is a snapshot and will differ at the next build.
What happened
With the now-shipping AMD EPYC 9006 "Venice" SP7 server processors sporting up to 256 Zen 6(C) cores per socket, or 512 cores in a 2P configuration, you may be wondering if Simultaneous Multithreading (SMT) is still worthwhile on these increasingly high core count processors. Long story short, SMT on AMD Zen 6 is still definitely worthwhile from a performance and power perspective. I was curious myself and ran some benchmarks to explore the SMT impact on the 256-core EPYC 9996 as well as the 96-core high frequency EPYC 9686F processors.
