Just saw for listings for brand new Ryzen 3950x's for $499 to less than that. Buy it now or best offer prices. eBay.

I ask **Why** considering another 3950X when a 5950X sells NEW for the same $499 price from a proper legit vendor like Amazon or Newegg.com. eBay should be a last resort vendor.

Installs into the same motherboard that your 3950X inhabits.

I added it to my wish list on Amazon just in case anyone is interested

The 5950X makes for a dream

The 5950X makes for a dream machine. I have mine pimped out in rainbow colors & a transparent case. It's currently doing a little over 750K RAC without a sweat ( Corsair water cooled ) with an RTX 3060 inside. I play Factorio while it is crunching and it barely alters the UPS/FPS ! All that for $800 AUD which is ~ $500 USD. I used to follow the very latest when I was young, buying new gear all the time, but now I do a major upgrade around every five years & so this will me do nicely. I think AMD have hit the sweet spot in the market.

Cheers, Mike.

I have made this letter longer than usual because I lack the time to make it shorter ...

... and my other CPU is a Ryzen 5950X :-) Blaise Pascal

I'm sure "All that" cost rather more than $USD 500! :-).
(Apologies -- I just couldn't resist -- I did fully understand you were just talking about the CPU) :-).

Seeing as we all seem to be after 'bragging rights', I'll show you one of my machines I'm very proud of.  I used to try to keep track of each one by having a 200 page notebook with a double page for each host where I'd record hardware details and a log of 'dated events' so if there were future issues, I could consult all the past history.  I still try to keep it up but it's super hard as the number of pages and entries keeps growing.

A couple of years ago, I started developing scripts to grab current information of interest so that the most likely event of forgetting to manually record hardware and software changes could be obviated.  Below is an example of the script output that I can get immediately, any time I like, for any machine in my fleet.  I can login to any machine on the LAN, over ssh, using a variable based on the last octet of its (static) IP address.  In this case the hostname happens to be g4560-05, which tells me it's the fifth machine I built with that particular CPU.  'psa' is a small function to tell me the basic status of the machine and some BOINC related stuff.  I was quite surprised to see that 'boinc' itself has clocked up over 12 hrs of CPU time.  That's a little over 50 secs per day so not much load from just the client.

One further function (inf) provides details of potential interest to me.  I have colour-coded stuff here so what's posted here is pretty much exactly as I see it in a terminal session.  Once again, 'inf' is fairly small.  It invokes a whole host of other functions (stored in a separate, much larger file called .bashex), together with some Linux utilities.  The hard part is sorting/editing/displaying just the bits I want, in an easily readible form, for a diverse range of hardware generations.  Functions to do all these hard bits are in .bashex and I do keep adding/revamping stuff in there from time to time.

When launched, 'inf' auto-updates  .bashex - if needed.  With an 800+ day uptime (and a blank page of logged problems in my notebook) it would certainly have needed the update - actually an initial install, since .bashex probably didn't exist 800 days ago :-).  I haven't looked at this machine in a very long time so I was quite relieved to see that inf/.bashex did a pretty good job for this collection of different hardware generations.

I had forgotten that this host actually had an old PCI SCSI (from an old HP server - late 1990s) disk system that seems indestructible.  I acquired a bunch of these and usually replace with an SSD these days if the host needs any maintenance.  There are still a couple somewhere in the racks of working machines :-).

Since I usually have a range of different kernels installed, I highlight the running kernel in magenta on the initial line of the output.

Another item of interest (as the last output line shows) - the above old clunker of mine has a RAC about the same as your dream machine :-).  (Hurriedly ducks for cover and departs the scene.) :-)

Cheers,
Gary.

The prices on the 3950x CPU

The prices on the 3950x CPU seem to be collapsing nicely (at least on eBay).

But the prices on the Epyc ROME series of cpus appear to be resisting (on eBay).

Any guesses when EPYC ROME prices might begin to decline as the gen 1 prices have?

Probably not until the next

Probably not until the next generation, Genoa comes to market.

Looks like the Epyc 9000

Looks like the Epyc 9000 series (Genoa) cpus are launching on the same date as the Ryzen 7000 cpus at the end of this month.

ooooooh man, those look

ooooooh man, those look nice!  You gunna grab one?  I was also keeping my eyes one the 7000 series threadripper (hopefully bringing back NON-pro with this line up and hopefully will bypass exclusivity rights this round).  Im on fence between that and my children's college.....  Maybe i can pick up a second job.... or whatever happened to this "free college" talk politicians talk about.  The day that drops, papas getting a threadripper.  lol

You're SOL when it comes to

You're SOL when it comes to getting a non-Pro Threadripper.  AMD has abandoned that market.  No reason to support it when AM5 Zen4 will do the same.

They have released TR-Pro to the DIY market now.  No exclusivity now.

If you need the connectivity of Threadripper along with the core counts, you are forced onto the TR-Pro platform.

I honestly think that if you don't absolutely need the clock speed or overclocking of TR-Pro that Epyc supports your needs just as well with more options actually.

Certainly if you stay with the older ROME Epyc's or Milan Epyc's.
