Core wars, comment wars
Intel's make-or-break 18A process node debuts for data center with 288-core Xeon
288 cores, no hyperthreading, all drama: homelab dreams vs AMD flexes
TLDR: Intel unveiled a 288‑core server chip built on a new, more efficient process, aiming to pack more work into fewer machines. Commenters split between hype and hesitation—dreaming of homelabs, questioning the no‑hyperthreading design, demanding AMD comparisons, and cracking “286 cores” jokes—because consolidating servers could shake up cloud vs on‑prem choices.
Intel just dropped a 288‑core beast for servers, and the comments lit up faster than a data center Christmas tree. The new Xeon 6+ “Clearwater Forest” uses only efficiency cores (no hyperthreading—the trick that makes one core act like two) and a fresh manufacturing recipe called 18A (think: smaller, more power‑efficient transistors). It’s aimed at cloud, telecom, and edge AI, promising built‑in AI math blocks and 5G radio boosts so you need fewer add‑on cards.
But the community? Oh, it’s divided. One camp is drooling over the idea of stuffing this into a home lab—“one day” money only—while pragmatists want benchmarks vs AMD’s 192‑core EPYC before crowning a winner. Skeptics zeroed in on the all‑E‑core design: can a swarm of tiny cores beat fewer, beefier ones? Others cheered the giant 1GB+ cache and “drop‑in” compatibility for existing server sockets as a practical upgrade path for crammed racks.
Meanwhile, the cloud vs on‑prem crowd threw elbows: one pro claimed these core‑dense chips help win arguments to keep workloads local and cut cloud sprawl. An AMD loyalist waved price tags from the second‑hand market, calling EPYC the smarter buy. And the comic relief? “Why not 286 cores?”—a glorious dad‑joke nod to 80s Intel lore. Systems land later this year; comment wars start now.
Key Points
- •Intel launched Xeon 6+ “Clearwater Forest,” its first data center CPUs built on the 18A process, with up to 288 Darkmont efficiency cores.
- •The design uses 12 compute tiles on 18A, two I/O tiles on Intel 7, and three base tiles on Intel 3, integrated via Foveros Direct 3D and EMIB.
- •Darkmont cores feature microarchitectural upgrades and the package offers ~1,152 MB last-level cache, with four-core blocks sharing ~4 MB L2 each.
- •Platform features include drop-in socket compatibility, 12 DDR5-8000 memory channels, and 96 PCIe 5.0 lanes, 64 supporting CXL 2.0.
- •Intel targets telecom, cloud, and edge AI workloads; single-socket approaches 288 cores, dual-socket 576 cores; systems ship later this year.
