Precision 7730,5530,7530 (Coffee Lake) pre-release

Looks like the relative performance catogory, the p2000 mobile performs between the gtx1050 ti and gtx1060 thou closer to the former.

So basically there's absolutely no reason to go with the xeon over the i9 with no support for ecc whilst having the same core counts and cache.
So why would dell even bother having the xeon option?
Maybe xeons are more reliable and will last longer?

 

With the 5510 and 5520, the best Xeons were always a little faster than the best Core i7 in terms of clock speed... With the introduction of the Core i9, this isn't the case anymore, so I'm just as confused as you.
[Edit] Actually, I think I saw something like the Xeon supports vPro but the Core i9 doesn't?

TechPowerUp's "relative performance" is not based on benchmarks, but is just a "guess" based on the specs.

 

Don't forget the I7 version of 5530 is also 8850H vs 8750H in XPS (something like 400mhz difference I think?)

I suppose the Xeon point is the CPU does support ECC so if you were going to run ECC you would just configure to 8GB and buy aftermarket ECC RAM, I Suppose? Also the Xeon is 200Mhz difference for 100$ less than the i9. But I agree from my point of view, if you're already at 2500$ laptop what's 2600$?

Also if you spec with xeon they MAKE you pick windows for Workstations which is a 150$ surcharge too, so really i9 ends up CHEAPER than the xeon in the end.

 

It's been demonstrated that aftermarket ECC memory does not work with a Xeon-equipped Precision 5510. Probably the same will be true with the 5530 (otherwise, they would offer ECC memory, why not?).

I suspect that, even though the CPU supports it, they didn't "hook up" the ECC pins from the memory module to the CPU memory controller.

 

That's a good point you make about having to pay $150 extra for the workstation windows jazzman
Given the small casing, I think the i9 will most likely throttling before reach the max clock speed.
So with this in mind, I'd probably be better to just get the i7 and save $250 over the zeon or i9.
BTW I'm located in Australia so the pricing is around 12% more.
Aaron44126, is there any way to hookup the ECC pins to the CPU memory controller?

 

I was just speculating about that being the reason, but it's the best that I can come up with... Anyway, if it's correct; no, the CPU is soldered onto the motherboard and there is no practical way to connect anything to it (and that would be a yucky hack anyway). These should be traces that go across the motherboard and they may have opted not to include them to save physical space in the motherboard layout.

I believe i9 will be able to operate at max speed but only for a short period of time before having to throttle down, if a full CPU load is sustained. For a more periodic/burst load, it may be fine. (Testing required...)

Can someone confirm whether the 5520 tb3 is 2 or 4 lane.
I've heard Xeons don't have their own graphics and relays solely on the dedicated. Is this true?

Also comparing the i9-8950HK to the Xeon® E-2176M the later Xeon has:
-Intel® Trusted Execution Technology
-Intel® Stable Image Platform Program (SIPP)
-Intel® vPro™ Technology
Does it make a difference?

Mobile Xeons do have integrated graphics. Precision 5000 series uses the Intel graphics to drive the display always, with the NVIDIA GPU providing rendering support when needed. (There is no way to disable graphics switching, shut off the Intel GPU, and have the NVIDIA GPU run everything, as you can do on the 7000 series.)

Those three Intel features are used only for specific, specialized workloads. You can look each of them up individually but chances are you don't need any of them.
