Precision 7530 & Precision 7730 owner's thread

I'm torn to be honest. Did I mention I'm up to 5 dead pixels now. Who inspected this panel, Stevie Wonder? I'm on a time restriction for a major project and the rest of the machine is so good that I might wait it out for a new panel.

The prices on the customization options for the ZBook Studio G5 and ZBook 15/17 G5 are absurd. This can't be right?
I did get an incredible quote from Lenovo on their P52 though, same config as my 7530 but roughly $500 less. It's tempting but I need to do more research.

 

I just read the maintenance manual of P52 and 7530. My conclusion is, P52 is simply better.
It is more solid though not easy to dissemble, and has better keyboard, big battery, 2.5 inch+ 2 m.2 slots. as well as hdd/ssd, wireless indicator, a nice 4k screen.
7530 might be thinner, but who cares?

 

45% gamut is a joke. It is perhaps only slightly better than a black/white TV. Can you imagine that?

 

7530 also cools and performs better.

 

It is more solid though not easy to dissemble
Can you really judge the solidness by a few drawings in a service manual? And ease of disassembly means higher user servicability.

better keyboard, a nice 4k screen
Keyboard is user preference and the Dells can also be configured with 'nice' 4K screens.

big battery
90Wh. The Dell can be configured with either 64 Wh or 97 Wh.

2.5 inch+ 2 m.2 slots. as well as hdd/ssd,
Duplicates. Also, the Dell also allows this. The only remark you can make is that the Dell doesn't allow a 2.5" drive along with the 97Wh battery. You could turn this remark around; "The Dell can have up to 3 M.2 drives!"

wireless indicator
Ah yeah, you got me there.

The point I'm trying to make is: They're both competing products that are very much alike. Finding out which is better for you will take more than looking at service manuals.

 

this is really hard to say.

hard to say. I remember dzeek has a p52. And i did not see 7530’s performs better. Yes 7530’s cpu is 90w/60w, p52 is 77w/55w.
But the real performance difference is small. 7530, when cpu is 60w, temperature is close to 100 degrees, when 90w, simply cannot hold it.
Beside, p52’s p3200 performs slightly better than 7530’s, right?
Besides, 7530 is not a quiet machine in my view.
I guess we need wait more 7530 and p52 users, so that we could really compare their performance. Or simply wait for the notebook check review.

 

P52's design is more like a an evolution of precision M4800. A traditional machine. I mean you could really read its maintenance manual yourself. P52 has palmrest, chasis assembly which serve as a 'roll cage' like on a car, bottom, bottom cover. So motherboard is securely sandwiched between chasis assembly and the bottom. On the other hand, 7530 simply do not have this chasis assembly (roll cage) layer. That is why I say P52 is more solid. You can argue 7530's palmrest also serve as 'roll cage', but I do not think so. the metal (hold the keyboard) on 7530's palmrest is simply a thin piece, not as solid as a reall 'roll cage' system. Anyway, I personally really prefer P52's design, it simply give me more confidence.

P52 has a 90wh battery, the same time you can have 1 2.5 device and 2 m.2 device.
7530 with 97wh battery, has 3 m.2 device.
I think business user might prefer 2.5+2 m.2 to 3 m.2. Sometimes you really need a 2.5 device. 2.5 ssd is simply cheaper and has more capacity, and has better protection since it has a metal cover. But m.2 device is 'raw', just like ram, you can only expect the bottom cover could protect it.
actually, if Lenovo is smart enough, they can simply turn the 2.5 bay compatible with 2 m.2, just like P51/50 does, in that case, it might have totally 4 m.2 device. But anyway, as I said, I think 2.5 + 2 m.2 + big battery is a reasonable design.


4k screen, led indicator, keyboard, well, as you said, it might be a personal taste. But I would not say dell has advantage on these things.
P52 has a 4k touchscreen, you can say it is a little grossy than 7530's matt screen. But man, it is brighter (400 nits) and it is a touchscreen. A touchscreen usually means its surface is covered with gorilla glass or sometime that might offer better anti-scratch ability. I just don't know if it has pwm issue. If it is pwm free then it is perfect in my view.

P52 and 7530, in my view, are not very much alike. P52 is more a traditional mobile workstation. 7530 might be more 'modern' because it is thinner. Actually I am not sure why Dell wanted to make it thinner. As a mobile workstation user, I don't need it to be thinner.
As to performance, it is hard to say. There are not many P52 users out there and there is no notebookcheck review, it is hard to compare now. Many people say P52's thermal design is worse than 7530. But, actually they judge this only by picture and they don't even have P52 themselves, this is not convincing.

Besides, same configuration and same service, P52 is about $500 or so cheaper. And honestly, I don't see why 7530 worth such a price premium.

You don't have to agree with me at all. Those are simply my personal opinion. If I have to pick between P52 and 7530, personally I might pick P52.

 

It's been proven through benchmarks that the P52 does throttle CPU under heavy workloads. I encourage you to read the thread here:
http://forum.notebookreview.com/thr...hp-zbook-15-g5-or-lenovo-thinkpad-p52.820474/

TL;DR:

P52 throttles resulting in worse CPU performance. However, it has a higher power version of the P3200 if you go that route, resulting in better GPU performance.

They're both good choices in this space though, so it really comes down to user preference. It sounds like you've made your decision.

 

thank you man, appreciate your reply.
I have 7730. Those are just my comments.

 

Quick update; after reaching out to Dell's support team 3 times now and giving them a piece of my mind, first and second times just referring me to tech support again, they are configuring a new replacement machine with expedited shipping. They also said that they'll be inspecting the new unit thoroughly to make sure it's perfect. Order confirmation says it's to arrive by the 8th and I can hold onto my current system until I receive the new unit.
I'll post my impressions of the new system once I get it and maybe a little comparison with the current one.
