Why there is almost no difference between 1950X and 2950X?

 

They're the same core count at 16c/32t ea. The 1950X precision boosts up to 4.2, and the 2950x precision boosts up to 4.4. They are both 180W. So i'd bet they have to keep the boosts almost as low on the 2950x to keep it in the 180W area.

 

I think, the part is agesa (new agesa was in few tests a little worse than new, ussually legacy tests) and clocks. SIngle thread will be better of course, but multithread in load it could be extra 100 MHz on new TR. And more depends on cooling setup, with liquid setup will be difference higher for new TR2.

 

I don't know about single threaded performance. A lot of that performance on Ryzen came from Cache improvements. The 1950X already had those improvements baked in. At best you might see SLIGHTLY lower memory latency, but there isn't much improvement to be had.

 

Pre-order is in...need to upgrade my rattletrap 1950X...

 

Im thinking about "only" 2950X

 

It's Cinebench, I wouldn't expect most of the latency improvements to improve scores there drastically. That said, for people buying these CPUs with 4 dies , latency likely isn't a top factor.

 

I haven't read many reviews, but what latency improvements? Threadripper already had lower latencies than Ryzen 1xxx. It was on par or greater than Threadripper 2xxx. 0.8-1ns L1, 2.7-3.0 L2, and 9.5-10ns L3.

 

Does anyone know if there will be any ASUS WS class motherboard released, with 18 to 24 Power fazes capable to handle the 2990WX for prolonged workloads at 1.3 volts?!(as IN heavy duty rendering for a week or two non stop_and not a 2 second cinebench run).
MSI has a 16 faze one that is just good enough to run stock 1.1/2volt with XFR, unless someone will make a decent Monoblock or a very good VRM block.

I also think that with a decent motherboard, a LN" cinebench run will definitely score above 9000 points...possibly just over 10/11k if the memory controller is really good.

 

It'll just be a clone of the retail model with workstation features as they've done in the past unless they released a retail model with 16 phases first. The Zenith requires 1.400v to get 4000mhz to maintain stability ( in TTL's video ) whereas the 16 phase MSI board only needed 1.360v for 4050mhz. 50mhz and 40mV lower. You'd also get 70A parts ( infineon doesn't list these on their own site ) vs the more common 60A.

 

Thats not true, my Zenith Extreme and 1959x combo is ok with 4230MHz (Im lucky for 1950x ). I have not issue with any vrm limitation. Look at vrm components here. The same vrm as R6A or R6E. And i9 7900x series are more power hungry in practice after agressive OC...

 

Asus Zenith Motherboard is a total piece of crap
....its got an extra 8 PIN EPS that Your 1950 X doesnt even use...its a last minute motherboard using the same template they have been using for years now....ASUS is not the King of the hill anymore, not because there is someone particularly better ( which Gigabyte might likely become), but simply because at ASUS what they care about is selling You the cheapest piece of crap over and over at the highest possible price, and sticking an ROG badge for a threadripper motherboard should offend You that owns one much more than Me that I dont yet, because for a TR4 socket putting a ROG label is a massive downgrade......ASUS has become the same as their TUF line....rebranding and dropping in less and less quality and innovation as time passes.


It il be very very interesting to see in the coming months how many people get their PC on fire or electrocuted and see ASUS in court, for having allowed a bios update to RUN W series on the Zenith so ruthlessly.

 

HEVC performance in the first few reviews is very disappointing. Flagship ties or loses to 8c TR1.

 

WR in Cinebench:

 

the whole power phase thing, its really just about keeping your vrm cool. i dont have a spec sheet on hand, but at least 60 amp power stages seems common, and most TR boards are at least 8 phases, so thats 480 amps. that's 624-672 watts at 1.3-1.4 volts. that'll be more with more phases or higher rated stages. as long as you keep vrm cool, under 90c, then thats fine. they typically don't start derating until something like 105-125c. put a fan on vrm, you'll be fine.

 

First post updated with info about reviews

 

Any ideas on why the initial Passmark Benchmarks are so low for the 2990?

 

Hey guys just got my system up and running.. So far so good. I have my 2990wx stable at 4.05ghz.. i could probably push it more but it seems to do better on some benchmark scores at this speed then it did at 4.1-4.2ghz. Memory i have settled in at 3200. Consistent 6300 on Cinebench15

 

MB?
Bios OC or in Windows?

Been playing around with my MSI MEG and 2990WX. Compared to Asus/intel OC, this BIOS interface is.... a little... hamfisted...

Gotten a nice bump in geek-bench so far:
Bone stock:
https://browser.geekbench.com/v4/cpu/9607264
single: 4905 multi: 46923

https://browser.geekbench.com/v4/cpu/9609374
single: 5399 multi: 62045

 

This is windows 10, MSI MEG Motherboard, Current Bios, and yes Bios Overclock. And wow big difference with geekbench on linux vs windows ... my overclock is slower then your stock!!!

https://browser.geekbench.com/v4/cpu/9622803

 

Yeah windows is a boat anchor on this chip right now...

Are you just changing the multiplier? Any other settings?

 

Did you install windows natively or move it over from another machine? I can't get past win10 demanding drivers in setup to do a clean install...

Dug up a sata DVD drive - manually browsed to every dir on the provided DVD and it doesn't find anything that gets me past this...

 

Mine did a NDIS network crash every time when i tried bringing over my m.2 over.. i had to format and reinstall

 

You guys with the MEG can you test something for me please - Balanced power plan - put the system to sleep and see if it will wake after half an hour - I know it's an ask but need to know!

I have the MEG currently with a 1900X till 2950X becomes available.

Initially the 1900X would not down volt or down clock under windows balanced power plan - was stuck at 3800MHz and 1.4+ volts with no XFR working......MSI sent me beta bios 121 and that fixed the issue.

With both official bios available on MSI site the system would wake from sleep if woken within a few minutes of having been put to sleep.....if left for more than say 20 minutes it would try to wake, debug code would start cycling then stop at debug code 00 and the system would be frozen, both reset and power buttons on case and motherboard were non functional and only way out of the freeze was to turn off power at the wall socket. Beta bios 121 would not wake from sleep no matter what and would always freeze with debug code 00 and need a hard power off at the wall socket to get back up an running.

Also there is an issue with setting SOC voltage and having it apply when memory frequency is set above 2933MHz.

MSI have replicated the issues and say they are working on a fix....how long it will take who knows.



Also if anyone has a CRDOM drive attached vis SATA and they experience any weird PCIE lag or detection problems when opening file explorer and having it load up the drives or HWiNFO64 freezing at "detecting SCSI/SATA" when loading up sensors it may be due to the rom drive as there seems to be some sort of detection issue for some reason, your millage may vary with this one but there is definitely some issue going on on the detecting PCIE device level.


I even had Disk Manager hanging big time with "Connecting with virtual disk services" while trying to load up disk drives. With the cdrom drive disconnected no issue with opening up Disk Management. Once I managed to get drivers installed for the cdrom drive things became more stable but it was a PITA of a process.

 

So no one can do the wake from sleep test with the MEG?????

 

I've got a bunch mangled in the BIOS at the moment and I'm putting on a water block. Not sure if it will produce a valid result, but I can try...

Tried to resume after about a minute...
- mouse would not resume
- keyboard would not resume
- hit reset... hang at code E1
- hit reset again... Brought me back into windows as at the same point I left off when I hit "sleep" from the taskbar menu.

So, something definitely amiss...

 

yeah something is amiss...….Like I mentioned with the official bioses I could resume/wake form sleep sometimes if I tried to wake the system within a few minutes of having put it to sleep. Leave it a little longer like 15 - 20 - 30 minutes and hard freeze with debug 00 and hard power off at the wall socket was the only solution.


Well so I've been told by MSI Tech they have reproduced the issue and are working on a fix so lets see how long it takes...approaching the 1 week mark tomorrow so......

 

And what bios setting is that that allows you to set wattage limit for cpu????


Is it a parameter only visible with Gen 2 TR or am I missing the obvious ????

 

1. Enable "expert" at the top of the OC page for "OC explore mode"
2. Go into "CPU Features"
3. Set Precision Boost Overdrive to "Manual"
- set Power/Current values as desired (make sure you understand what this means - a BOATLOAD of current will be sent your CPU's way!)

@ 4.1GHz 1.32v I'm seeing 450W sustained in RealBench stress...

If you open Ryzen Master, you will see these limits defaulting to 250W and 200A IIRC. I bumped them up to 650W and 600A (ludicrous values that the VRM can provide, but I can't likely cool, but I'm going slow with the voltage).

 

Ok thanks, yes I've seen the PBO settings but they only work/apply with gen 2 TR so I'll look into them when I drop a 2950X in soon.

 

Will certainly tap into this thread further once I get my 2990WX Build up and running with the MSI MEG Creation (Had to ditch Zenith Extreme as it does not have what it takes)

 

I've done pretty well with 4.1GHz OC so far, but what I am seeing so far is that PBO/xfr+ 4.2+ is asking for ludicrous voltages (1.45-1.5+) which are pretty terrifying coming from Intel 14nm OC. I'd much rather see peaks at 1.35-1.4.

I'm still trying to wrap my head around their architecture and voltage requirements - given that I know the chip will do all-core 4.1, I'd like to have it able to do 4.2+ on small jobs still have 4-4.1 for all-core work. I can't seem to find a config that does not either require uncomfortably high voltages or instability when allowed to be more dynamic.

 

I thought the 2950X was supposed to be available on shelves today, 31st here in Aus!!!


So where is it????

 

The 2950X is up on Amazon, I ordered one.

Guys, advise please what water-block to buy for 2990WX+MSI CREATION X399? EK or BYKSKI A-RYZEN-THV2-X?
