Intel ends support for this 28-core Xeon CPU

Intel has initiated the “End Of Life” (EOL) procedure for its unique Xeon W processor with 28 cores and unlocked multiplier. Originally designed to compete with AMD's Ryzen Threadripper processors, the Xeon W-3175X offers a high core count and attractive overclocking capabilities.

“Market demand for [Intel Xeon W-3175X] products […] It has moved to other Intel products, ”a Santa Clara company said in a statement, although the company has not disclosed whether it intends to offer an unlocked Xeon for workstations soon. For regular workstations that aren't designed for CPU overclocking, Intel offers its 38-core Ice Lake-SP-based Xeon W-3375 and 32-core Xeon W-3365 processors. Those interested in purchasing the Intel Xeon W-3175X will have to order it by April 29, 2022, while the last shipment will take place on October 28 of the same year.

Intel originally showed its Xeon W- processor 28-core 3175X at Computex 2018, noting that it could run at 5.0 GHz with all of its cores activated. It quickly turned out that it was possible to get 5.0 GHz when overclocked and cooled pretty extreme, but it was still impressive to see a 28-core CPU running at such a high frequency. Ultimately, Intel set the processor base clock to 3.10GHz, as well as 4.30GHz as the maximum Turbo frequency in single core. However, since the chip features an unlocked multiplier, owners may overclock it beyond 3.10GHz.

The CPU has a TDP of 255W, but when overclocked it consumes a lot more, which is why motherboard manufacturers for the Xeon W-3175X have had to implement quite high-performance voltage regulation modules (VRMs) with 30 stages of power to power the processor, which made such motherboards very expensive. To that end, only ASUS, EVGA, and Gigabyte offered suitable platforms.

With a price tag of $ 2999 and the need for a rather expensive motherboard along with an advanced cooler, six-channel DDR4 memory and a high-performance power supply, the Intel Xeon W-3175X has never been a very popular option even for extreme workstations, perhaps also because AMD offered Ryzen Threadripper processors with more cores at a lower price.
