Still configuring a P73--Why no i9 and NVIDIA Quadro RTX5000 16GB?

I have no need for ECC ram  avaialbe for the xeon but unclear why can't have more Vram with the i9.  Some of my applications eat up VRAM and it would be nice to at least have 16GB.  The top xeon processor seems to score about 20% under the i9.  I keep my laptops until they are geriatrics so woul dlike to keep it adequate for as long as feasible.   I have one ordered with the xeon but will cancel if waiting will result in the i9/16GB option.  Is it a quirk of the ordering software/availability or perhaps heat issue?  Appreciate any comments.

Re: Still configuring a P73--Why no i9 and NVIDIA Quadro RTX5000 16GB?

It is simply a result of the way Intel, nVIDIA and Microsoft have structured things.  All the CPUs are soldered; the windows license is flashed onto the motherboard.  GPUs are all soldered.  Just looking at obvious options, there are 4 CPU choices, and there are 5 possible GPUs.  That gives 20 possible combinations.  There are 3 windows license options (pro, home and none); that makes 60 combinations. TPM option makes 120 possible combinations, and AMT option makes 240.  There are other options.  Manufacturing, spare parts and repair becomes impossible.  Offerings are limited to the more commonly chosen ones.  My guess is that this situation is unlikely to improve.

Thank you for commenting.  Understood about offering every combination is not practical or cost effective.  Seems to me that the i9 processor with the fastest gpu with 16 GB vram would be a reasonable option to make available.  I have no clue what is the best configuration for what I use.

Re: Still configuring a P73--Why no i9 and NVIDIA Quadro RTX5000 16GB?

I am planning to buy one of the 15" P series machines, but I want to see one of the OLED screens before I choose a config.  I am not sure how much difference there will be between the RTX 4000 and 5000 will be in a mobile machine.  The desktop version of the RTX 5000 uses 230 watts by itself.  The laptop power supply is 230 watts, so the GPU is obviously running in a reduced mode.  I cannot find any real comparisons.  I think I will choose the i9 because it has a much higher passmark score than the Xeon and I am guessing the the RTX 5000 won't make up the whole difference.  If I spent my day doing 3D rendering, I might think differently.

You can get an external TB3 video card enclosure and have more VRAM by using a desktop video card.

Appreciate the input thus far.  I see the RTX 5000 is almost 1200 bucks more than 4000.  In my order I have only paid a 200 or buck premium vs a similar i9 equipped laptop. It seems like a  vey nice "deal."

It does seem quite a bit faster.  I do have some GPU intesinsive programs. However, as you say this was not under laptop conditions.

I am thinking I should cancel my order and redo it with the i9.  I really do not know enough to make an informed decision.   Either are probably fine, but want to future proof for as long as possible.  My W510 has been a great laptop.

regarding your statement "I really do not know enough to make an informed decision.", that is also why I haven't done anything.

Well, I tried to do my due diligence looking at benchmarks, but there is no substitute for experience.  That is why I posted here.  The RTx 5000 does look much faster but may not apply fully to the P73.  Just looking for a bit more of a push one way or the other.  If there is no clear hard data, welcome informed opinion.   The i9 option does save a few bucks but that is not an overriding factor for a system that will hopefully be used a long time.  Thanks again for any comments.

The XEON processor has a faster core frequency than the i7-9850. They are both 6-core CPU's, but the XEON tests faster.  Whether you currently need ECC memory or not, having the XEON CPU will afford you the option should you choose.  Also, the installed Windows 10 OS is the Workstation edition and not the Pro so there are a couple of extra provisions contained within the OS for the file system and some other items none of which are particularly relevant to a laptop. I've been selecting XEON processors with all of my laptops (with the exception of the X1Yoga2) since they became available (P70, P1, P53). I also have been selecting RAID 1 storage configuration which has come in handy in the past when one of the SSDs bought the farm. Smiley Happy
