Precision 7670 & 7770 pre-release discussion (Alder Lake)

[TheVlad]

Hi all

 

Is 4k 120Hz on 7770 OLED?

I see people mentioning OLED here, but the DE website says WLED...

Thanks

Precision 7670 4K panel is OLED, 60 Hz, 16:10.

Precision 7770 4K panel is LCD/WLED, 120 Hz, 16:9.

(Yet another trade-off.)

If I was getting 7670 and there were two 4K options , I'd probably go for WLED even if both had 60Hz, so for me personally I wouldn't call it a trade-off. I know OLED has come a long way, but I still don't completely trust these panels to not "burn-in" (out?) with time

well, not long ago a lot of people didn't want SSD's. because they didn't trust that they wear out over time...

 

I'm using OLED Displays for years without any issues. (yes with static images like Taskbar,...)

Kingston FURY Renegade PCIe 4.0 NVMe M.2 SSD appears to have a higher specification than the Sabrent Rocket 4 Plus SSD 4TB.

 

7300/7000 v.s. 7000/6850 MB/s Read/Write

4 PB v.s. 3 PB write durance

1,000,000 v.s. 700,000 IOPS

OLEDs do dim over time but I doubt that you will get an estimate that for new screens tells how normal PC use will result in x percent dimming after 1000/2000/5000 hours of use.

About the current DGFF cards and especially that special order 3080Ti maybe @Dell-Mano_G can tell us if there are plans to offer it for users of the Alienware 51m or some previous workstation laptops?

Dell would have a great way to distinguish itself by making this possible.

DGFF cards have generally not been compatible between different laptop models.  The only potential working upgrades that I am aware of are what they offered officially for the Alienware 51m, and a Pascal->Turing option for Precision 7X30 systems using Precision 7X40 cards.  You can look at the Precision 7X70 cards (service manual pics) and see that both the physical layout and data connectors are different than any previous DGFF implementation.

 

Dell has typically not offered the cards stand-alone.  Don’t really blame them — despite the interest from users on sites like this, the overall market for an upgrade like this would be quite small and it would be extra hassle for Dell to figure out how to support them for warranty purposes and so forth.  However, you can’t even get them through the spare parts dept. if you know the part number (in most regions) — I wish they’d make that possible.  Have to rely on eBay or other sites for stuff to show up, maybe several months after the system launch.

That is rather depressing.

 

I was fully expecting to be able to at least buy different cards within a series but it seems they do indeed not want to see these out in the open which is a shame. The same goes for the complete lack of support for the 51m chassis that has been advertised as upgradable and modular but with little to none of that having any positive effect for owners.

There is a chance that 7X80 cards (NVIDIA Lovelace) will work in 7X70 if they keep the same chassis and don’t mess with the GPU card layout (very much).  Wouldn’t plan on that being the case, and any upgrades beyond that would not be likely to work at all.  😕

And if rumors are right,  you will need a 450W Power supply for the new cards 🤣

I think it would be easier to just get a TB3 eGPU instead, especially now that the mining craze is has died down. They work quite well when the system has no built in dedicated GPU and in a way are even more reliable than using a TB4 dock for connecting many displays.

Turing --> Ampere may also be possible with the 7X50 systems using 7X60 GPUs.

Only for the 5 seconds that it takes for the system to throttle down to about half of that so no need for a new power supply 😄

I haven't heard of anyone trying this, so maybe?  When I looked at comparison photos of the GPU it seemed like there was enough of a small difference (screw positions maybe) that would rule it out.  Don't remember exactly, would have to pull the photos and look again.  There is also the fact that 7X60 GPUs are PCIe4 and use one fewer DGFF connector than 7X50 GPUs so that throws cross-compatibility into question as well.

Today is the day that my 7770 order is supposed to hit "shipped" status.  (Supposedly it has been making its way from the factory in China to the FedEx hand-off point in Chicago over the course of the past week; no way to track that progress.)  It did not ship early and there is now definitely a chance that it will ship late.  It's still pretty early in the morning here.  I know shipment notices sometimes don't arrive until evening.  We'll see.....

Have not followed developments in that area for a long time, last I looked TB3 was limited and if I remember correctly having less performance than a 3080 due to TB3 (and TB4) bandwidth limitations. Looking forward to TB5 or whatever it will be to finally let external top of the line GPUs run at max performance.

Doubt we'll ever have a high-end GPU running externally at the same speed that it would internally.  While Thunderbolt might get faster, internal PCI Express is also getting faster.  Still, if a desktop 3080 can achieve 80%+ performance attached externally in most cases, it's probably still faster than a laptop 3080.

...Plus, running with an eGPU would remove power contention from the CPU, allowing that to run faster as well.

I also doubt we will ever be at 100% but it would be nice if with for example a 3080 Ti mobile and a 3080 Ti eGPU we would get at least halfway in the direction of the desktop card. From what I saw last year of a laptop 3060 and 3080 vs their eGHPU counterparts they were both slower than what could be achieved in a Clevo X170 and that wasn't so great.

Dell has failed to "ship" the order by the given ship date, July 24.  At this moment, the ship date has not been updated, it still shows July 24 as the estimated ship date on the order status page.

 

I am nosing around to see if I can get someone to provide more information about where the system is right now.  Someone inside Dell should be able to track the freight shipment containing my package, which is probably moving via DHL Air Freight.

 

...If they really are using DHL Air Freight for the shipment containing my laptop, no surprise that the system did not "ship" yesterday, as there were no DHL freight flights into Chicago.  There was one already early this morning at 3 AM.  Maybe it will "ship" today.

[Aaron44126]

Sigh.

 

I went through Dell customer support / order support and got a useless response, with the rep there saying that the system is still in the "final stage of production" (even though it has been in "Build complete" status for nine days now), blaming COVID and the global supply chain situation for delays, and saying that he would put in a request to "expedite" my order.  I think he was just trying to placate me with a mostly canned response and get through his queue.

 

Simultaneously, I contacted a Dell employee that I've seen posting on another site and he got me a more detailed status.  The order is in "shuttle" state, moving from the factory to the U.S. to be tendered to FedEx, and is estimated to land in the U.S. tomorrow.  So, just gotta keep waiting a bit longer.  😬

 

(This sort of information would be really nice to see on the order status page... or at least, the order shipping/delivery dates should update to reflect the reality that clearly Dell knows about.  😕)

[Reciever]

Hurry up and wait!

It sounds like yours is really close! Mine is still stuck in "Confirmed" so it will probably not arrive until mid-August if I had to guess.

And now worse news:

 

"The Chinese city of Shenzhen told 100 major companies including iPhone maker Foxconn to set up "closed-loop" systems as it battles COVID-19."

I don't know if Dell factory is affected 😭
