With the launch earlier this 12 months of Intel’s Ice Lake Xeon Scalable platform, the primary Intel enterprise platform based mostly on 10nm, we have been all the time questioning to what extent this silicon would penetrate different markets. Today Intel is answering that query by launching the Xeon W-3300 household, utilizing the identical Ice Lake Xeon silicon however in a extra centered single socket platform. Xeon W-3300 will supply processors from 12 core as much as 38 cores, peaking at 270 W TDP, however providing help for as much as Four TB of reminiscence.
The Xeon W-3300 Family
This is the third technology of Intel’s Xeon W processor household, initially highlighted by the overclockable 28-core Xeon W-3175X based mostly on the Skylake household of enterprise CPU architectures. Intel made a giant effort with the launch of that processor, and adopted it shortly with the Xeon W-3200 collection based mostly on Cascade Lake, providing extra PCIe lanes and a rise in frequencies. The new Ice Lake Xeon W household makes use of Intel’s Ice Lake structure, as we highlighted in our preliminary Xeon Scalable evaluate of the platform, affording a sizeable gen-on-gen bump efficiency enchancment in opposition to the earlier Intel processors. In that evaluate we’ve highlighted that Ice Lake provided +19% IPC enhance, and the achieve in core depend and TDP supplied an uplift regardless of some regressions in frequency in comparison with Cascade Lake.
While the Xeon Scalable line gives as much as 40 core variants, Xeon W-3300 will go so far as 38 cores, however Intel is focusing totally on the 32-core model as its lead product. The new Xeon W-3365 with 32 cores is designed to be aggressive in opposition to AMD’s Threadripper Pro 3975WX, which we lately reviewed, providing the identical variety of cores, the identical DRAM help, and has some tradeoffs.

The prime processor is the Xeon W-3375 with 38 cores and 76 threads. The base frequency of two.5 GHz is offset with a 4.Zero GHz single core turbo and a 3.Three GHz all-core turbo, enabled by the 270 W TDP, which will increase the TDP of the highest Xeon W processor from 255 W within the earlier technology.
All the processors will help 64 lanes of PCIe 4.0, 8-channel DDR4-3200 reminiscence (up from 6-channel), and with 256 GB LRDIMMs as much as Four TB per socket (16 modules). The customary Ice Lake enterprise core gives 1.5 MB of L3 cache per core, and for all of the processors right here that customary stays the identical, nonetheless the 12-core model makes use of 1.75 MB of L3 cache per core. Intel has not disclosed the die configurations of the decrease core depend elements, nonetheless the 28+ core elements are nearly definitely utilizing the 40 bodily core configurations.
These new processors use the identical LGA4189 socket because the mainline Xeon Scalable platform, however are enabled by a brand new technology of C21A chipset which permits for Wi-Fi 6E and Thunderbolt Four growth on motherboards ought to the board OEM constructed it in. Further details about the C21A has not been detailed right now.
The different angle new to the Xeon W household is the addition of latest directions for cryptography – Ice Lake cores now help SHA extensions, have doubled AES throughput, and VPMADD52 instruction units. On prime of this, Intel is pushing its newest technology of DLBoost know-how to hurry up AI workloads by environment friendly use of the on-board AVX512 models….
