Precision 7750/7550 release date?

As far as I know, the COVID virus has shifted the plans of many companies. Because the research and development work in most companies was either completely stopped, or went very slowly the last 3-4 months. Therefore, even the output of such significant models as the next Apple Iphone's is shifting. The production of commercial samples of the DDR-5 is difficult despite the fact that the final version of the standard has already been released. I read that the main problem is that not only memory modules should be released, but also the corresponding chips, controllers for motherboards (south bridges?). Intel is in no hurry to connect support for DDR-5 due to the peculiarities of the transition from DDR-4 to DDR-5. This is not the first time that Intel has postponed the release of new processors and the transition to a 10-nm process technology. As you and I know perfectly well, Intel has left the tick-tack-tick-tack-tick strategy and switched to the tick-tack-knock-knock-knock model. This means that the release of processors and chips with support for DDR-5 will definitely be delayed by at least 2023. This is too long. My home park (4 powerful laptops) needs to be replaced. All laptops are already 11-12 years old. I need to buy powerful work laptops in the very near future (I can only wait six months). I read that Lenovo 74 is already being tested. It turns out that it is better not to wait for new Precission, since they will not bring anything fundamentally new (differences in the performance of 10 and 11 versions of Intel processors will be no more than 3-5%). So?

 

I think we will still see DDR5 systems in 2022. Yes, COVID-19 is affecting all sorts of stuff... But at the moment we are looking at a few months and not years. Even Apple's iPhone refresh that you mentioned is unlikely to be delayed by more than two months. People are learning how to deal with the new situation in which we find ourselves and things will start getting back on track.

The difference between 9th gen and 10th gen CPUs is not impressive. The difference between 10th and 11th gen will be better, I think. Whether we get Tiger Lake or Rocket Lake, it will put the H series on a "Cove"-style architecture for the first time which means a ≈20% IPC boost. (11th gen CPUs will get around 20% more work done than 10th gen CPUs when running at the same clock speed. Some workloads could see up to 40% improvement.) Ice Lake is already on this architecture. You can look at performance comparisons. Low-power Ice Lake CPUs have been shown to be competitive against higher-end 8th and 9th-gen desktop CPUs (in single-threaded performance).

If Tiger Lake H-series is what we get next-gen then it will also finally move the mobile workstation lineup to 10nm which will bring a decent power efficiency gain, hopefully making Intel CPUs look more appealing when stacked against what AMD has been putting out.

Still, if you are waiting for 11th gen then you are looking at a good 12-14 months from now. If you want to upgrade before that, then the products launching around now with 10th-gen CPUs are probably the best you are going to find. There could be some AMD systems dropping over the summer but I haven't heard anything about any of the main mobile workstation vendors putting out AMD systems yet.

Samsung is still looking to launch DDR5 modules next year. It looks like Intel will support it first in Sapphire Rapids CPUs (Xeons for servers) next year as well. I'd be rather surprised if they do not include it in their 12th gen desktop CPUs (late 2021 or early 2022) and 12th gen H-series CPUs (mid 2022). It's too soon to get good information on that.

[Edit]
Finished writing this and checked my news feed to find another article indicating that Alder Lake will (maybe) get DDR5 support.

I read the article on your link. I am very grateful to you for it. Hassan Mujtaba spoke very clearly and correctly. In the near future (1-2 years) nothing significantly new will happen. And Intel's plans are very vague and, as usual, the transition to a 10-nm process is delayed. The 11th generation of Intel processors will not bring anything new. As we see recently, the very high TDP is becoming the main problem with Intel processors. High heat dissipation can become a very serious obstacle for the release of mobile processors, as inside laptops, where there is very close and there is not enough cooling, the processors will overheat and run into throttling. Comet Lake and Rocket Lake will still be manufactured at 14nm. However, as I think, releasing 2 generations of processors is not profitable due to marketing. Therefore, in the next six months, the maximum that we will see will be only Comet Lake. The release of Rocket Lake will definitely be delayed until the end of 2021 (in order to successfully sell the Comet Lake processors). Correctly?

It is also not clear when a new version of the SATA interface will be released (SATA 4.0?). This is necessary for the functioning of next-generation drives (fast SSD's). What do you think about that?

Given that only DDR-5 is a highly anticipated technology, it becomes very sad that Intel is in no hurry to add support for this technology even in Alder Lake (these processors will most likely come out much later than 2021. I suppose that this will be the end of 2022 of the year).

In your opinion, is it true that at the current time there is some evidence that the new 10th generation processors from Intel are getting hotter and have TDP closer to 200 W?

 

The article is about desktop CPUs which will be stuck on 14nm through 11th gen at least. Mobile workstations may get Tiger Lake for 11th gen which is 10nm.

Intel has repeatedly stated that their target timeframe for the CPU refresh cycle is 12-15 months. Since Comet Lake is just now rolling out, this means that the earliest that we are likely to see Rocket Lake is probably spring 2021. They could be a bit earlier since it seems that Comet Lake was originally expected to hit in the winter and seemed to hit some snags on the way out. It was originally expected in the January/February timeframe. (See 5th gen Broadwell vs 6th gen Skylake for precedent here. It took them so long to get Broadwell out, but Skylake was ready just a few months later.) Anyway, Alder Lake would be "a year or so" after Rocket Lake drops.

Intel has been hitting a consistently yearly cycle with their H-series refresh. 8th gen Coffee Lake dropped in April 2018. 9th gen Coffee Lake refresh dropped in April 2019. 10th gen Comet Lake dropped in April 2020. Not hard to guess when to expect 11th gen. If they use Tiger Lake then they will not be tied at all to the desktop CPU cycle. There will be low-power Tiger Lake chips out before the end of this year.

We don't need SATA 4.0. SATA is on the way out for SSDs. For fast SSDs, get NVMe drives which attach directly to the PCIe bus and do not use SATA at all. Current NVMe drives are already in the neighborhood of 6× faster than SATA drives. PCIe 4 will double the available bandwidth for these drives, and PCIe 5 is on the horizon as well.

I have heard that 10th gen desktop CPUs can run 200W+ at maximum turbo boost. I don't pay such close attention to the desktop side of things. In the Precision line, the power limit from the BIOS caps these CPUs much lower than that.

 

From what you said I think that USB 4.0, SATA 4.0 and DDR5 are useless.
For me, USB 4.0 will be replaced by thunderbolt in the near future, making it useless, Sata 4.0 will flop like Sata Express did (which nearly doubled the bandwidth from Sata 3.0), furthermore NVME would be faster anyway, and DDR5 isn't really usefull if the frequency doesn't make a big jump, I think it would be better to upgrade with DDR4 3600MHz than upgrading with DDR5 4000+MHz, gain from newer generation of DDR memory is smaller and smaller due to how it work, for more memory bandwidth there is two solution, increase frequency or increase memory channel (like from dual to quad channel).

What do you think about Xeon mobile processors? They seem to be faster than i9 and they have a different architecture. Does it make sense to buy a Precission based on these processors?

 

TheQuentincc
An increase in the memory frequency leads to an increase in the CAS/RAS timings. And an increase in the memory channels leads to a very complicated chipset. Correctly? If it were just to add a couple more channels for memory, then this would have been done many years ago. So, the problem lies in greatly complicating and increasing the cost of chipsets that support many memory channels. Right?

 

This is not true. The mobile Xeons have the same architecture as the Core H series. They are not based on the server Xeons. They are not faster than the i9. The only benefit of the mobile Xeons is ECC memory support.

DDR5 will supposedly have twice the memory bandwidth of DDR4 and (slightly) lower power usage as well, running at 1.1V. Don't know yet if the bandwidth boost will make any practical difference in terms of how applications perform. I imagine that it will be a minimal boost for all but very memory-intensive workloads.
USB 4 is basically USB 3 + Thunderbolt 3 rolled together from what I can tell. Not much different than what we already have.

 

increasing memory frequency is far more beneficial than lowering the timings, between a cas 19 and a cas 14 kit, the different in performance is very marginal, meanwhile 2666MHz vs 3400MHz is a big improvment.
increasing memory channel is the only way to get more memory bandwidth in the future, DDR technology is now to a point where the difference between DDR4 and DDR5 at the same frequency and timings would not be really visible. The difference between new DDR revision is that they increase the timings but also increase the frequency and decrease voltage, that's the only "big" difference and that's why they are making a "new revision", to make things easier for compatibility, look at these short review comparing DDR3 vs DDR4 with the 6700k :
https://www.hardware.fr/articles/940-5/cpu-ddr4-vs-ddr3-pratique.html
https://www.anandtech.com/show/9483/intel-skylake-review-6700k-6600k-ddr4-ddr3-ipc-6th-generation/7
As you can see frequency is the main factor here, DDR4 is faster than DDR3 because it loose timings, increase frequency with a better chip quality/design, that will be the same for DDR4 vs DDR5.

 

Is it true that Intel Optane is the fastest SSD, but can’t install them in a laptop because of the form factor? What optimally fast and inexpensive SSD on MLС chips can be installed in a laptop? I was interested in Samsung products, but experts at various forums say that Samsung has very problematic firmware and there is a chance of losing all data. And Intel often encounters the "8 Mb" error.
