AMD Ryzen Threadripper PRO 7905WX and 7900WX CPUs Leaked

Hardware tipster momomo_us has once again discovered unannounced AMD gear - today's tweet points to a pair of Ryzen Threadripper 7000 CPU families. Team Red's "Storm Peak" processors received some attention at the tail end of May, thanks to CPUID releasing version 2.06 of CPU-Z which contained newly updated "preliminary support" for the Ryzen Threadripper 7000 series. Industry experts anticipate that this Zen 4-based product range will shake up the workstation and HEDT markets upon arrival - with predictions of a Q3 2023 launch window. According to the leaked listings posted by momomo_us on social media—future workstation PCs will be catered for with AMD's PRO "79x5WX" family, and HEDT systems will be best served by non-PRO "79x0X" variants.

Prior leaks allege that the Ryzen Threadripper PRO 7905WX "workstation" range will be compatible with AMD's SP5 socket. This high end platform should support 8-channel DDR5 memory, and be capable of running up to 128 PCIe Gen 5 lanes and 8 PCIe Gen 3 lanes, although it lacks CPU and memory overclocking functions. In contrast the Ryzen Threadripper 7900X HEDT range is expected to offer full overclocking support for CPU and memory—but tipsters reckon its appeal could be limited by the platform's SP6 socket being restricted to 4-channel DDR5 memory configurations and a maximum 64 PCIe Gen 5.0 lanes—as seen on AMD's EPYC 8004 "Siena" family.

Very promising but I am very concerned about issues that plagued earlier iterations like lack of direct memory channel access and bandwidth issues, scaling issues, poor AMD optimization for the windows scheduler, system stability. Having to restart your computer through Ryzen Master is awful for a workstation product.

Nope, not going to get another Threadripper system!! :laugh: Not to say I wouldn't love another one....

That only applied up to the 3,000 series. The 5,000 series just came out & doesn't have that problem

On anothet note whats the point of the non-pro threaderripper?
I can asure you AMD has no plans for anything other than "Threadripper Pro", the non-pro are too limted to be true usefull to power user that was onemajor complaint of TRX40 was the 256GBs limit of ram. Threadripper pro however could address 4TBs of ram.

Also there is a threadripper pro boards that has wattage control & some sort of pbo suppor for it. So techinally they are overclockable dependable on board. Overclockable if the support is there. I think it only goes up 400 watss on the cpu though.

If you absolutely love Computing Threadripper was the Cat's meow. $50 adapter cards that would let you test RAID 0 on M2 was great but the amount of I/O made the Thermaltake Level 20 seem perfectly sized. Too bad AMD abandoned us but I am not hating as some of the boards on AM5 are sweet like the MSI Ace boards but cannot talk to a $399 As Rock X399 in terms of wiring.

I am genuinely excited about the advancement of Threadripper PRO. Why not make the chips interchangeable with the AMD Eypc SP5? Allowing for a multitude of motherboard opportunities. My biggest crumble as a threadripper pro lover - NO BODY offers a smaller formate motherboard - ITX, MTX - barely two to three ATX.

I be more worried with quality control. I don't want to wake up in the morning to the nice rich smokie smell of PCB/Plastic/Electronic parts. Heh.

And Asrock is the only one to make mATX and ITX-long Epyc boards.

Correct - and Asrock Rack does make them for the new Xeon 2400 and 3400. Intel has there base covered across the board.
Supermicro makes a smaller M-ATX board for the Xeon 2400/3400 too!
Need this same love for the AMD Threadripper Pro family!

It would be nice if they actually supported consumer TR this time around, instead of changing sockets almost as often as Intel does. I'm still rocking a 2nd gen TR more for its lanes, and it still stings that there is no upgrade path for it.

I agree with you 100%. It comes off just as soon as the new product comes and the socket changes leaving you as if what you just spent your cash is not just a thing of the past. At this point, I have a three series 3975WX, and at one point considered the five series IF I could find one-second hand. I would not pray retail for it at all. From my point of view, not worth it at all!

I really hope they actually support the consumer as well!

I'll echo wanting a consumer version as well, just don't make any promises you won't keep and tell us there will be an upgrade path of you don't follow through. I have 1st Gen Threadripper, man was it revolutionary for that time! Thankfully I didn't get 3rd Gen and get screwed by no upgrade path like many else did

Did anyone else have the Asrock X399M Tachi motherboard? At one point, I considered that motherboard. I know processor I would take a step back, but the real thing - the three PCI 3,0 x 16 PCI lanes was the biggest holdup.

I always wondered if AS rock would have made an updated version of this.
