Intel’s Flagship HEDT Processor, The 28 Core Xeon W-3175X Listed Online – Could End Up Costing Around $4000 US

Dec 16, 2018

Intel’s flagship Xeon W-3175X processor which will be featuring 28 cores has been listed by online retailers. Designed for the LGA 3647 socket, the new processor is supposed to launch this month and the listings reveal that we may be getting close to the launch of Intel’s only answer to AMD’s Ryzen Threadripper 2000 family.

Intel Xeon W-3175X 28 Core Processor Listed Online – Aiming Price of Around $4000 US?

The Intel Xeon W-3175X is without a doubt the flagship chip that Intel will have for a while. It will be marketed as an ultra-enthusiast and premium processors and the prices that it has been listed for reflects that.

The Xeon W-3175X processor features 28 core, 56 threads and boasting a base clock of 3.1 GHz and a boost clock of 4.3 GHz out of the box. It features 38.5 MB of L3 cache, support for DDR4 6 channel memory (2666 MHz speeds) and 68 PCIe Lanes (44 CPU, 24 PCH). The interesting part is that it will feature full overclocking support since it comes with an unlocked design and allows up to 512 GB of memory support.

Now we have four different listings for the processor from various online retail stores. You can see the listings and prices below:

  • Intel Xeon W-3175X (Ediscomp Listing) – €3449,15 or $3900.81 (Pre-VAT) / €4138,98 or $4680.97 (VAT Included)
  • Intel Xeon W-3175X (Lance-Nakupy) – €3790,40 or $4286.74 (Pre-VAT) / €4548,48 or $5144.09 (VAT Included)
  • Intel Xeon W-3175X (Kikatek) – €4039,54 or $4568.51 (Pre-VAT) / €5997,38 or $6782.72 (VAT Included)
  • Intel Xeon W-3175X (PC21) – €3517.24 (Pre-VAT) / $4220.68 (VAT Included)

Now based on these prices, we can give a little feedback of who this processor is really built for. If you take a look at Intel’s Xeon Platinum 8180 which is the more Datacenter tuned version of Xeon W-3175X (both have identical core configuration) but costs $10,000 US, the Xeon W-3175X looks to be aimed primarily at workstation builders and enthusiasts. Even for enthusiasts, it won’t make a whole lot of sense unless you are into heavy content creation.

Intel really doesn’t have a chip design with more than 18 cores that they can accommodate on the existing X299 / LGA 2066 socket and with AMD going for 32 cores and 64 threads on the same TR4 socket, a year later, Intel had to come up with a plan. This is Intel’s solution, but whether it works or not at the given price is something to be seen as AMD still offers more cores and threads, even the PCIe lane count from the CPU is higher and the chip itself would be half the cost of what you’d end up paying for the processor, let alone the memory and motherboards. There are only two boards that have been unveiled to date which feature support for the Xeon W-3175X and even they were not shown in a completely final state.

There’s a lot that needs to be done but considering Intel will have a new core coming out in the coming years, we can expect a resurgence of Intel back in the HEDT department which AMD has got a major grip of in the recent years with their Threadripper platform.
