Thanks for the clarification it’s been unclear on which models actually have vapour chamber meanwhile competitors are making a big thing of it. I’m glad the 5680 has some extra power headroom vs the 5570 and 5770 also. Which cards qualify as high end requiring the vapour chamber?
-
Good to hear dell pro support have always been excellent for us also a real differentiator and pretty flexible when they can be! However our company has a fleet of 300+ precision laptops so these sort of tweaks aren’t on the agenda really so for us it’s more interesting to see the capabilities out of the factory. I am suspecting from the images the 5680 lacks vapour chamber also 😞
-
🙂 unfortunately not really an option for us, business values stability and warranty over tweaks like that! The surprise for me was I didn’t see a huge difference between 7770 and 5770 in GPU heavy loads rendering using iRay only saw a 5% difference and similar 5-10% in Open GL pro graphics workloads. This wasn’t the same across the board for instance an RTX a2000 running at 40W In a precision 5570 was more than 20% slower than the same card in a Precision 7670 running at 80W (IIRC) how much difference did you see for various workloads? For me there just seems to be some really efficient points along the power curve but if it’s right at the bottom end you lose more performance. will be interesting to test out for the Ada generation, especially if we get a bigger than 130W power supply to allow for higher sustained lower Regarding the 5680 I haven’t had power supply confirmed yet but some press articles mention power delivery; “Extended Power Range (EPR) technology means more power (165W versus 130W) can be delivered through a universal USB-C connector.” https://develop3d.com/workstations/dell-launches-13th-gen-intel-core-precision-laptops/ So 165W atleast so I’d hope for more like 80W+ graphics power…..if it can cool it.
-
Yeh that’s what I was meaning the ram and power supplies listed didn’t match the specs that had been shared with me prior to launch, I don’t recall if a graphics power rating was shared but I’d hope for higher than 65W in the old 5770 I found the performance of the RTX A3000 in the 7770 and 5770 were remarkably similar even doing tasks such as GPU rendering which use 100% GPU power. To be frank that challenged my assumptions! These ADA cards have such a wide power range so it will be be interesting to see where the performance and efficiency curve is on these different GPUs. I’ll try and clarify atleast the power supply today along with asking on cooling. I suspect the spec sheets were a little rushed since this model is further out with a may launch date
-
Unfortunately there is an error on the spec sheets I’ve had it confirmed it’s soldered ram compromise for the small size. maybe CAMM in future versions! Also I believe it is a 180W power supply with the discrete graphics which would make sense for the new up to 5000 series graphics will confirm later as that is based on my memory of briefings we had on this while it was still under NDA. I can confirm it is a ground up design as a precision, also need to confirm if it has Vapor Chamber cooling like the old 17inch version based on the xps 17,

Not sure why Dell were so slow to update the drivers, for a long time i've avoided their recommended ones though! . looks like the same security vulnerabilities were fixed in 517.88 that i have been running for a couple of months now released 20th Dec 2022, see https://nvidia.custhelp.com/app/answers/detail/a_id/5415 for me I stick to the NVIDIA advanced driver search https://www.nvidia.com/Download/Find.aspx?lang=en-us and then stick to the same branch as is certified for the Pro software we use. Currently that is 515 so i go with the latest starting 51 unless i have an issue then it's just try the latest driver etc.
-
yeh already they have confused the Desktop Professional cards by releasing the “RTX 6000 Ada Generation” which replaces the RTX A6000 I don’t understand why they can’t just have an L prefix for pro cards. This is what they have done on the data centre side with the new L40 replacing the A40 RTX L2000, L3000, L4000 etc would we easier to distinguish from one generation to another and crucially for me the Professional and Consumer cards which became harder to communicate once the Quadro branding was removed
-
Look like we might get ADA generation professional graphics in this generation after all https://videocardz.com/newz/nvidia-rtx-workstation-ada-generation-mobile-processors-spotted with Intel releasing much earlier than previous generations i though we might just see a refresh but if they are leaking out now then maybe…. :-)

We’ve found the WD19DC/S reliable in recent years. I remember the first TB-16 docks were a horror show we gave up on them and went back to the old display link docks even though they weren’t ideal. However once we tried the WD19DC things were gradually more positive with just a few BIOS/firmware updates needed before rolling out company wide. Have been pretty rock solid for us running precision 7740-7760 worst I’ve had reported has been occasional need to reboot the dock by pulling the power cable and reconnect everything. I think of them as a small computer so expect to have restart them on occasion as they are in an office and run for long periods . Only briefly tested with precision 7670 and 7770 but didn’t note any issues so far. They do only deliver 210W vs 240W from the power supply but you can always connect the power supply also when worried about absolute peak performance

Exactly You see this with many manufacturers of electronics regardless of terms, NDA etc some people seem willing to break the law and leak parts out and well China supply chains in my experience are less strict about which laws they choose to follow! To be honest I see little gain in this one, I’m not sure who is buying them and for what purpose?! I’m just happy the chassis on the systems we are receiving are good quality and Dell chose not to ship items with sub standard parts. That is QA working in my opinion
-
We shall see, Still waiting on my orders for 7770! Also interesting I ran a couple of rendering applications and with A4500 held at around 100W whether I loaded the CPU or not. When I loaded the CPU and GPU 100% the cpu power limit dropped as low as 35W and the GPU sustained at the same 100W it ran at when I loaded the GPU alone. all of this is reported from HW info
-
Oh dear well hopefully things will start to improve. I just got a 7670 with i7, 64GB ram and A4500 Just run cinebench r23 multi core of approx 14500-15000 it has a 75W PL1 and 157W PL2 but after an initial spike to 100 degrees on some of the P cores it settles to around 2.6GHz at around 75 degrees on p cores and 1.9 GHz and 70 degrees on e cores. Seems like a bit of headroom for a higher power limit. This is in an air conditioned office around 21-22 degrees typically these are commercial systems so we won’t be using things like throttle stop but maybe something in a future BIOS update will allow a bit more headroom given it seems to be there thermally.

From what I heard all chassis were affected, but it will interesting to see if different chassis options take longer.we ordered these not long after launch. The explanation I was given is Dell had a batch of chassis that they just weren’t happy with the quality of and therefore all orders were help up, our estimate went up by about a month on all orders but now most look set to beat that by 15-20 days 🙂 Much as the delays have been inconvenient fair play to Dell not sending products out they aren’t happy with the standard of. They seem to be taking extra care on the QA also to make sure what goes out is right and still beating their revised dates, so I’m happy, I hope it will be the same for others.

Indeed, I can give some hope! Most orders have shipped. I’m finding they are staying at the “in production” stage for 7 days or more likely due to extra QA checks from speaking with Dell. Most entered production various days w/c 22nd August. Of these 3 orders shipped for 7670 thin, performance and 1 option of 7770 Only order yet to ship is one for the 7770 with i7 and A3000 which entered production a little later on the 29th. another order for 7770 with the i9 and A4500 entered production a few days earlier and shipped already. The earliest order to ship took around 7 days to make it from china to the UK. all these are without ssd door or smart card reader

Yeh hopefully not that much given the hassle you have had, I edited my post afterwards as I hadn’t checked if so dimm was live today 🙂
-
So dimm options are showing on the uk configurators albeit with errors I suspect it’s not adding the interposer to the build as it’s saying missing part error. also missing 64 GB ECC option currently which is what I would be going for over CAM. You can have 64GB non ECC however
-
If of interest you may want to see if So-dimms are quotable also they are showing on the UK configurator this morning although it seems a bit broken says missing a part (likely interposed). Hoping the price doesn’t go up for you via your old order 🙂 also the 64GB ECC ram I was hoping for seems to be missing currently
-
🙂 I’ve seen 3 orders enter production too for 7670 thin, performance and 7770, dell must be happy with the quality of the chassis on these now. On the one order that has shipped the eta didn’t improve once it went to “In production” and did take longer in this stage than usual (likely extra QA) But hopefully yours will be the same and beat the current estimate. On my order that have shipped just crossed the previous eta out when my order shipped early and gave a new earlier eta on the tracking link. Never seen issues like this that weren’t covid/ wider supply chain related and some credit to dell for not releasing products they were not 100% happy with the quality.
-
I heard this week so shouldn’t be long to wait at-least for factory builds 🙂 can’t remember the exact day but given dell usually do things on a Tuesday I’d say today or tomorrow most likely
-
Cool I’ve got 64GB and 128GB models coming… eventually! Will run Cinenbench when they arrive and see how they compare. Until some more get tested we don’t really know what is “normal” for these hopefully more people will start receiving them sook . Certainly wouldn’t expect the lower speed 128GB CAMM module to make much difference apart from if there is a specific issue I was told caused the cancellation (should have been a hold but they cancelled it!) It could be your laptop slipped out before they noted the issue, or could have just been a batch of modules with the issue which affected my order. I didn’t place orders till more like mid July due to holidays and since then everything has been slowed down waiting on chassis Dell are happy with the quality. I would rather have it that wa round though! However with Pro support you don’t have any worries In my experience they will do anything it takes to sort issues. Had some early Precision 5750s replaced due to power throttling issue that couldn’t be fixed with firmware and they just replaced them with no fuss 🙂
-
Interesting, 85W power limit sustained isn’t bad, but still seeing low scores is odd. Id like to see higher than 85W with low GPU usage though given the total power budget. . I’ll check my 7760 soon see how it compares for PL1 and PL2 I know that varies the PL1 value when you load up to GPU heavily. couple of other thoughts - Are you still running process lasso during the tests? Maybe worth disabling that. - The other thing is one of our early orders for precision 7770 around mid July with 128GB CAMM got cancelled and the reason given to us was performance issues with the 128GB CAMM. The others with 32GB and 64GB did not. it’s been rebooked now but i don’t know if it was a BIOS/other firmware type fix fix or something else. Worth asking tech if they are aware of anything though. We are yet to recieve any of our 2022 generation machines ordered in July but will certainly do some testing when we recieve either 7670 or 7770 as have ordered a few different specs of each.

Without wanting to turn this into a political discussion be aware MicroStar International (MSI) are one for the few PC manufacturers still doing business in/ with Russia. That rules out purchasing anything from them out for me. see https://som.yale.edu/story/2022/over-1000-companies-have-curtailed-operations-russia-some-remain

Hi @Dell-Mano_G I think I was too late, was this recorded or will the content be available some other way/ be repeated, I wasn’t aware of the client community let alone this webcast!
-
yeh I’ll have to do some testing again but definitely saw the reported values in hwinfo atleast one of the change when I hammered the GPU with a ray tracing workload (NVIDIA iRay) on one of the systems I was testing recently, pretty sure it was my 7760. This corresponded to a cpu speed reduction also but that could have been thermal related also. Generally for that particular workflow as it doesn’t hugely benefit from cpu cores I tend to run it solely on the GPU as performance gains are usually marginal and if you have cpu cores free you can work on other things. I some systems I’ve actually found it slower or perhaps more prone to errors due to software balancing between the two types of cores. I also noted an article on notebook check saying Lenovo posted GPU TGP for the P16 it would be good if Dell produced info for like this for comparison. @Dell-Mano_G Hp also tend to post more power info on their specs. However I tend to find for the most part Dell still outperform both historically. See https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad_P16_Gen_1/ThinkPad_P16_Gen_1_Spec.html?ver=48dd0cb9-2a22-49b9-8196-88dd94aa5784 not much on the CPUs However
-
Excellent while I’m more focused on professional engineering workflows it will be great to se me your feedback on the new chassis, performance and thermals. I would like to see the PL1 and PL2 values, through hwinfo although I’ve noted them Change depending on workflow on my 7760 if the GPU is also running intensively it seems to dynamically drop the power limits. So it would be nice to see maximum power values for cpu and GPU when running mainly cpu and purely GPU based tasks. we won’t get our first 7670 and 7770 units with pro cards (a2000, a3000 and a4500) until august thanks again for all the info you post and this review I advance!
