AMD EPYC "Turin" 9000-series Motherboard Specs Suggest Support for DDR5 6000 MT/s

[T0@st]

AMD's next-gen EPYC Zen 5 processor family seems to be nearing launch status—late last week, momomo_us uncovered an unnamed motherboard's datasheet; this particular model will accommodate a single 9000-series CPU—with a maximum 400 W TDP—via an SP5 socket. 500 W and 600 W limits have been divulged (via leaks) in the past, so the 400 W spec could be an error or a: "legitimate compatibility issue with the motherboard, though 400 Watts would be in character with high-end Zen 4 SP5 motherboards," according to Tom's Hardware analysis.

AMD's current-gen "Zen 4" based EPYC "Genoa" processor family—sporting up to 96-cores/192-threads—is somewhat limited by its DDR5 support transfer rates of up to 4800 MT/s. The latest leak suggests that "Turin" is upgraded quite nicely in this area—when compared to predecessors—the SP5 board specs indicate DDR5 speeds of up to 6000 MT/s with 4 TB of RAM. December 2023 reports pointed to "Zen 5c" variants featuring (max.) 192-core/384-thread configurations, while larger "Zen 5" models are believed to be "modestly" specced with up to 128-cores and 256-threads. AMD has not settled on an official release date for its EPYC "Turin" 9000-series processors, but a loose launch window is expected "later in 2024" based on timeframes presented within product roadmaps.

[...] The datasheet lists support for 120 PCIe 5.0 lanes—another significant upgrade over equivalent Zen 4 parts (96 lanes). [...]

Only Socket SP6 Zen 4 parts (8000 series, code name Siena) are limited to 96 lanes of PCIe. Socket SP5 has 128 5.0 lanes for 9000 series Genoa and Bergamo. SP5 has additional 2x4 lane 3.0 links as well.
The 120 number is probably specific to that particular motherboard design, most likely due to space constraints.

I was just thinking about when AMD will launch their new CPUs, will it be on 3nm? I want to gift this computer to my dad and buy a new one.

Probably grab everything when the new RTX GPU's drop, then again, that might change, depending what AMD does on their GPU front too. It will most likely be nVidia though, I play a lot of old games and AMD/Radeon GPU's doesn't always play too well with those, takes a lot more effort to get them going.

I very much doubt it. At least the regular variants wont be. It's possible that if the Zen5c based server models launch later in 2025 that those might use 3nm for space savings.
Even Nvidia with it's infinite coffers of cash still uses N4P for their next GPU.

4nm with a 3nm refresh later probably for the laptops only.
