Intel has announced that the Xeon W-3175X processor is available with immediate effect. This processor was first officially detailed back in October 2018. However, earlier in the year at Computex, it was the unnamed processor behind an Intel demonstration, overclocked to 5GHz with a 1770W water chiller unit attached.
Headlining facts about the new Intel Xeon W-3175X processor are that it has the "most cores and threads, CPU PCIe lanes, and memory capacity of any Intel desktop processor". Furthermore, this powerful Xeon features:
- 28 cores / 56 threads
- Intel Mesh Architecture
- Base clock 3.1GHz with Intel Turbo Boost Technology 2.0 for frequencies up to 4.3GHz, unlocked multiplier
- Up to 68 platform PCIe lanes
- 38.5 MB Intel Smart Cache
- 6-channel DDR4 memory support for up to 512GB at 2666MHz. Supports RAS and ECC memory
- Intel AVX-512 ratio offset and memory controller trim voltage control
- Can be tuned with Intel Extreme Tuning Utility, with memory overclocked via Intel Extreme Memory Profile
- Uses the Intel C621 chipset
- Is recommended to be cooled by the Asetek 690LX-PN all-in-one liquid cooler
- TDP of 255W
In Intel's own tests, the Xeon W-3175X processor was pitted against the Core i9-9980XE processor and achieved 1.52x performance in the Unreal Engine Infiltrator demo. Both systems sported a Gigabyte GeForce GTX 1080 (GV-N1080TTOC-8GD), an Intel Optane SSD 905P Series 480GB SSD, plus Windows 10 Pro 64-bit – but the Xeon system came with 6 x Samsung 8GB DDR4-2666 RDIMMs (rather than 4 x Kingston HyperX 16GB DDR4-2666 UDIMMs in the other system).
If you are interested in acquiring a new Intel Xeon W-3175X processor, it carries an MSRP of US$2,999. Intel directs potential customers to system integrators which regularly build powerful desktop workstations.
Der8auer delids the Intel Xeon W-3175X
Quick off the mark, with this video recorded earlier this month, der8auer offers a closer look at the Intel Xeon W-3175X and the supporting Asus ROG Dominus Extreme motherboard in his lab.
Not content with running this multi-threaded monster on the LGA 3647 motherboard using common-or-garden tests, der8auer does some thermal testing of the new Xeon after delidding it and replacing its stock thermal paste with his preferred Liquid Metal TIM.
In conclusion, the thermals after delidding and switching the TIM weren't as drastic as with some other Intel chips. However, this large processor's coolest cores could be up to 13 degrees cooler, while the hottest core was 5 degrees cooler. On average the cores were almost 9 degrees cooler with Liquid Metal paste (see chart above).
