Intel Xeon W-3300: Workstation processors with up to 38 CPU cores

Intel has introduced five processors from the Xeon W-3300 series, which for the first time bring their own 10-nanometer technology to workstation PCs. The series is closely related to the third Xeon SP generation Ice Lake SP for servers, but dispenses with multi-socket operation and comes with its own C21A chipset.

A Xeon W-3300 can only be operated individually on an LGA4189 mainboard, which, unlike server boards, can provide Thunderbolt 4 and Wi-Fi 6E, among other things. The top model Xeon W-3375 uses 38 CPU cores with 76 threads and clocks at 2.5 to 4.0 GHz. The all-core turbo is 3.3 GHz. The memory interface has grown from six to eight channels and can handle up to 4 TB of DDR4-3200 RAM.

Intel is thus adapting its own product range to that of AMD: The Ryzen Threadripper Pro 3000WX can also control up to 4 TB of RAM in octa-channel. On the connection side, however, they have 128 PCI Express 4.0 lanes, while Intel only has half of them. Xeon W-3300 now also support PCIe 4.0. AMD also continues to have a core advantage with up to 64 computing hearts.

Compared to its predecessor, the Xeon W-3275, the Xeon W-3375 has ten additional CPU cores, but the maximum Turbo is reduced by 600 MHz. The chip manufacturer increases the thermal design power (TDP) despite a new manufacturing process (14 vs. 10 nm) and lower clock frequencies from 205 to 270 watts.

The full expansion of Ice Lake-SP with 40 CPU cores is reserved for servers and data centers with the Xeon Platinum 8380.

In terms of price, everything remains the same: the top model still costs 4450 US dollars nominally (4460 euros at the current exchange rate including VAT, which is not included in US prices). The cheaper models with 12 to 32 CPU cores range as low as $ 950. PC makers are slated to start selling soon. Noctua already has customized CPU coolers announced for the new CPU version LGA4189.

AMD’s Ryzen Threadripper Pro 3000WX meanwhile still relies on the Zen 2 architecture. Zen 3 processors with 64 CPU cores are currently only available as Epyc 7003 alias Milan for servers – a short-term Intel counter-attack would be possible as Ryzen Threadripper Pro 5000WX.
