Intel Fall 2018 Event: Everything That Wasn't Streamed (Page 3)

By: Steven Bassiri from Oct 9, 2018 @ 10:00 CDT

Intel's Two Beasts


Intel has also seen demand for high-end desktop processors that sell in more niche marketplaces, and has devised two lines of CPUs to meet that demand. One of those lines includes just a single CPU.


Dubbed the Intel Xeon W-3175X, the 28 core 56 thread CPU will be a fully unlocked Xeon. It will use the same C621 chipset that current Scalable Xeon platform uses, and the CPU will feature 48 PCI-E lanes. It will also support 6 channel memory in the same fashion as the current Xeon platform, so it will have ECC and RAS support.


The TDP is 255W, but you will get a Turbo up to 4.3GHz with a base clock of 3.1GHz. It also features 38.5MB of cache. We should mention that while the 9th generation desktop processors for consumers feature two hardware fixes for exploits, this new CPU seems to be adapted from the current Xeon line, which does not.


We can and will speculate widely about the price of the 28 core beast that can hit 5Ghz with a chiller, but we will instead focus on CPU's that have a material price. Here is the refreshed X-series processor platform, a much more affordable platform that uses the X299 chipset. Intel didn't drop the ball with TIM this time, instead, they will solder the new 9000 series X-series CPUs. While they keep the same core counts and PCI-E lane count, Intel has made sure that every SKU from the 8-core to the 18 core features 44 PCI-E lanes.


While some of the lower core count Skylake-X 7000 series CPUs featured TDPs at 140W, the new CPUs will all feature the 165W TDP. Core frequency has been boosted a lot, and while more base frequencies will remain around 3-3.5Ghz, Turbo Boost two frequencies have been increased to 4.4GHz for all but the 9820X. All the CPUs have a Turbo Boost Max 3 frequency of 4.5Ghz, except for the 9820X, which is an odd CPU since there is already a 9900X with the same core and thread count yet more cache. Cache sizes vary widely and don't always scale evenly with core count. Intel seems to have had a change of heart and instead of charging $1,999 for their 18 core CPU is now only charging $1,979. Like the W-3175X 28-core CPU, these CPUs do not have the hardware patches the new 9th generation of desktop consumer processors have, but we are grateful they are soldered.


Intel isn't introducing any new technologies into the new CPUs, they have just improved upon their clocking rates and have made some tweaks here and there, so you still get AVX-512.


The MESH isn't anything new, but it's still very important since cores don't have to wait for other cores to finish to start working.


Here we see Intel pitting their 9980XE against AMD's 2990WX, and we can see improvements in specification applications, especially if it's a very mix threaded program that relies a lot on single threaded performance (Turbo Boost Max 3.0). We will test out the new CPUs when they are ready and pit them against what is on the market, but for now, this is a little teaser.
