HP Z6 G4 Upgrade

I was looking at ordering some more HP Z640 workstations for my work, but noticed that they just announced the new line of workstations. The problem is that they are using these new scalable Xeon processors and can not find a ton of info on them. For the Z640 build I was using the E5-1650 v4 since most of our applications benefit from higher clock speed over more cores (AutoCAD). It seems the closest new one is the Xeon Gold 6128, but the clock speed is lower. It does have more L3 cache. I did notice that the TDP is lower, but that is not something we care about for workstations. Anyone have any insight on the performance I could expect with the new processor?

The higher cache on the processor would be of benefit when working with AutoCAD. Add that with the latter Gold series's ability to take advantage of DDR4-2666MHz over the DDR4-2400MHz in the 1650 v4's and you do gain a small performance offset even though the clock speeds are reduced.

Thanks for the reply. I also see that the Z4 G4 has the option for the W series processors and has the W-2135 that has a higher clock speed (3.7 vs 3.6), but half the cache of the E5-1650 (8.25 vs 15). The boosted clock is 4.5 vs 4.0. Would the gains in clock speeds be offset by the significantly smaller cache size?
