Dell Precision 7530, HP ZBook 15 G5, or Lenovo ThinkPad P52?

https://www.notebookcheck.net/HP-ZB...0-DreamColor-Workstation-Review.258940.0.html
This is the ZBook studio 7th gen CPU version with Dreamcolor display. Hope it helps you.

 

I've been looking at these options. For my work i want the fastest single cpu possible, with good full core characteristics when running all 6 cores for simulations. i prefer to have more than 4gb of graphic memory, because cad eats that up. Extra gpu power is always nice.i also want to have 32gb of memory. Im taking it on bike so i don't want a too heavy laptop. The budget from work is about 2600€ excl tax.

I've looked at the 7530, but it's just so expensive with 8850H or i9 and the P3200 with the mandatory ssd bought with it.
The P52 could be nice, but i don't know much about the models and pricing, i used to have a P51 with the xeon, but i'm switching jobs. The keyboard and docking station are really nice though, altough the P52 doesn't have that docking solution.

Zbook is usually very overpriced.

XPS 15 is in the budget with possible a i9, but the 6 cores are going to struggle with the cooling. gpu is also a bit slower. very thin and light though.

Alienware 15 R4 is nice, but with 3,5kg (compared to 2,5kg of the other workstations), it's just too heavy. It does have fast cpu's (i9) and a fast GPU (1070gtx). cooling is very good.

MSI GS65, good performance but only a 8750H cpu, 1070gtx max q, it's also very light and fits in the budget. keyboard is shallow though.

(gigabyte) Aorus x5 v8, a full 1070gtx and 8850H overclockable cpu, with good cooling and is 2,6kg (2,5 after removing the 2,5inch hd probably). The notebookcheck review shows very high boost clocks as well. only bad thing is that it has g-sync, and for G-sync the display has to be connected to the gpu and optimus can't work that way. so battery life is only a couple of hours. This laptop is also not available in the netherlands and i'd have to get it from germany.

I am considering getting the P52, I'm hoping someone could help me decide between the 8850H and the Xeon model, apart from the slightly higher price and clock speed what other differences might one expect? Is the Xeon maybe better with the quadro range of Graphics cards, will it run hotter or colder? Any other things I have not thought of? Will there even be a noticeable difference? I'm looking to use it mainly for multi core usage.

 

Xeon can support ecc ram which can reduce error and crashes. It also has higher boost clock than 8850H.

 

I read people ruled out Razer - does it really run steaming hot? What other unbearable flaws does it have?
After continuously reading and contemplating what to get, it turns out that MSI and HP's Zbook remain the only viable options. (at least for me, plus based on the discussion thus far)
We never chatted about Macs, but I personally will never even pay a penny for their overpriced, average-looking, performance wise, machine.

Anything else worth considering?

 

Don't see if you got answer to this question, so
This graphics perfomance boost you got becouse with enabled iGpu intel grphics card will display anything to monitor and nvidia makes only background render then copy buffer to intel.
When you disable iGpu, then nvidia will display anything so in this case there is no buffer copies and renders directly to display.

If you intrested windows 10 with latest update also shows which gpu render to wich display in "advanced display settings"

 

Bear in mind the models considered in this thread. They're powerful machines, capable of maintaining that power (mostly) over time and have a modest visual design. They also typically come with next business day on site support options.

Razers run hot. The logo screams "video games are more important to me than work" and their support is... generally not rated very good.
