Intel stops shipping Xeon W-3175X, unique 28-core desktop processor with overclocking support

The Xeon W-3175X processor has long been a unique product, as Intel still does not offer other models in the desktop segment with 28 cores and a free multiplier. Released as an ideological response to AMD’s Ryzen Threadripper, this processor will leave Intel warehouses for good on October 28, 2022.

The public first learned about the Xeon W-3175X processor back in the summer of 2018, when Intel used a then unnamed sample to demonstrate the ability to operate at 5 GHz with all 28 cores active. Later, the company was forced to admit that to overclock the processor, it used a liquid cooling system with a so-called chiller, which lowers the temperature of the liquid below ten degrees Celsius.

The highest frequency achieved by this processor corresponds to 5.6 GHz – liquid nitrogen was used for cooling, and there was no computational load on the processor. In this mode, all 28 cores and 56 threads were active. To fully work with the Xeon W-3175X, special motherboards based on the Intel C621 chipset were required, which supported overclocking functions. The corresponding motherboards were released by ASUS, Gigabyte and EVGA; other manufacturers did not pay much attention to this niche product. The cooling system that had to be used with the Xeon W-3175X processor had to be compatible with LGA 3647 mounts.

Some potential buyers who hesitate to pay more than $ 3000 for a processor were at one time embarrassed by the fact that there was a plastic thermal interface under the cover. The Xeon W-3175X, among other things, required the use of six-channel memory, so when assembling a system based on it, their high cost was added to the problems of finding compatible components.

Intel Corporation decided to interrupt the market path of Xeon W-3175X this week, referring to the traditional shift in demand towards other products of the brand. Orders for the supply of processors of this model will be accepted until April 29, 2022, and the last batch will leave the warehouse on October 28 of the same year.
