The Intel Xeon W-3175X Review: 28 Unlocked Cores, $2999
by Ian Cutress on January 30, 2019 9:00 AM ESTTest Bed and Setup
As per our processor testing policy, we take a premium category motherboard suitable for the socket, and equip the system with a suitable amount of memory running at the manufacturer's maximum supported frequency. This is also typically run at JEDEC subtimings where possible. It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.
We changed Intel's reference system slightly from what they sent us, for parity. We swapped out the storage for our standard SATA drive (mostly due to issues with the Optane drive supplied), and put in our selection of GPUs for testing.

Not really, 3D rednering is done on specialized render farms, the modeling work, key framing etc. can be done on any decent modern mainstream CPU, and especially well on any modern HEDT chip, for prototyping and preview, once satisfied, send it out to render properly.eastcoast_pete - Wednesday, January 30, 2019 - link
The only scenario where this or similar Xeons do outperform the AMD lineup is if (!) the key application (s) in question make good use of AVX512. In those situations, Intel is still way ahead. In all others, a similar or lower priced Threadripper will give more bang for the buck.Tango - Wednesday, January 30, 2019 - link
There are scenarios in which this is perfect, and in fact my research department is looking into acquiring two of them. Our algorithms include both highly parallelized instructions and completely non parallelizable ones where clock speed dominates. We estimate models that take a whole weekend to spot out a result, and the alternative is paying top money for supercomputer time.At $3000 it is a steal. The problem is half Wall Street will be sending orders to get one, since the use case is similar for high frequency trading applications.

I expect all the review sites will redo their 2990WX benchmarks once Microsoft is able to fix the scheduler. The question is really... how long will it take Microsoft to fix their scheduler? That said, nobody should be expecting massive improvements. Some of the applications will improve a ton, but not all of them. It will be more like a right-sizing closer to expected results and less like hitting the ball out of the park.-Matt

Little professional software exists for Linux, so these machines WILL run windows for most parts.cmcl - Thursday, January 31, 2019 - link
Agree that there is more professional software for Windows, but in visual effects (where I work), 90% of our workstations (and all render) runs on Linux (24-core workstations, with P6000s), running Nuke, Maya etc. Apart from the gaming benchmarks (and who would buy one of these for gaming), a lot of the tests could be done in Linux as that software runs on LinuxIcehawk - Thursday, January 31, 2019 - link
Workstations aside, these mega-core beasts are run as VM hosts on bare metal. I don't have a single server here that just runs an OS & app suite, it's not 2000 anymore everything is virtualized as much as possible.WasHopingForAnHonestReview - Wednesday, January 30, 2019 - link
Holy shit. AMD absolutely bent intel over on this one. The price for performance ratio is overwhelming in AMD ls favor! Intel would have released this for 8k if the 2990wx wasnt so competitive!WOW!

They probably wouldn't have released it at all. As noted, most of these could easily be server cores on which they could make plenty more money. This appears to be largely a PR effort.jcc5169 - Wednesday, January 30, 2019 - link
Who in the world would buy this over-priced piece-of-crap?
