AMD Is Working On A Monster 64-Core Threadripper

[caldrin]

Threadripper was on their road-map for this year at the start of the year but then vanished.. so yeah i would not be surprised if they did actually release something at the end of the year.

I can only imagine the power draw for a 64 core at 4GHz. The 2990WX draws 350w on PBO. So 700w+ for the 64 cores??

 

Zen 2 has half the power draw at same clocks as zen 1/+ so same frequency with doubled cores should be about the same.

[dgsddfgdfhgs]

can we call 64 core TR a super computer?

Will Intel even have an answer to this ?

There is speculation going around Intel will use Cascade Lake for their next HEDT offering. The highest current Cascade Lake CPU offers 56 cores, 400W TDP. 2.6 GHz base, 3.8 turbo. Supports 12 channels of 2933 ram, but that'll probably be nerfed on HEDT.

 

If we assume AMD essentially stuff four 3950X into one CPU, that would be 64 cores, 420W TDP, 8 channel 3200 ram, 3.5 base 4.7 turbo.

amd will probably keep stock clocks a lot lower than that, tdp should be about the same as the current 32 core, they haven't increased tdp yet so i don't think they will

the most based of them all

Agreed, but was just using that for a quick indicator. For comparable TDP (putting aside differing definitions of TDP) AMD have a lot more clock headroom, so backing off that will improve power efficiency a good amount. I want to strap a chiller on one and see how far it goes... will see how rich I feel at the time. I already have a chiller, no I don't work at Intel!

the carnage is going to be massive, i guess its reviews will have to be rated R

does it have enough "power" though to maintain the low temps, if you push it i expect it will become quite hungry

also about the 'just oc the 9980XE' argument: the 9980XE needs a 360mm+ watercooler at stock, do you really think you can OC this without LN2

you can with a few 480s

It's an aquarium chiller, can't remember the specs but it is rated at a good fraction of a hp. I use it to cool a reservoir which will help slow any change. When overclocking a 7800X the 10L reservoir water temperature went up a degree or two from my set point of 2C. I don't know how accurate it is and didn't want to risk freezing.

 

I only bring this out for competitive benching, and power draw isn't a priority.

that should be more than enough then, do let us know how it goes if you do it.

wouldn't it make more sense to keep TR at 32 cores max or they will have a problem like intel where they are cannibalizing the xeon lineup (epyc in AMDs case)?

[The Benjamins]

My TR3k Predictions (all clocks are ±200 Mhz) ( Prices are ± $100 X, ± $200 WX)

 

3990WX - 3.2/4.6 - 64c128t - $2499 - 60+4 PCIe 4.0 - 4 Channel DDR 3200 - 250w TDP

3980WX - 3.2/4.5 - 48c96t - $1799 -  60+4 PCIe 4.0 - 4 Channel DDR 3200 - 250w TDP

3970X    - 3.6/4.8 - 32c64t - $899 -  60+4 PCIe 4.0 - 4 Channel DDR 3200 - 180w TDP

3960X    - 3.6/4.7 - 24c48t - $649 -  60+4 PCIe 4.0 - 4 Channel DDR 3200 - 180w TDP

Not really, amd doesn't have high clock server chips unlike Intel now.

On the stuff I tried it on so far, the chiller only gets me about 100 MHz over ambient water, so it isn't massive gains. But in competitive, every little helps. I'm not into it enough to look at more extreme cooling.

 

Plan for now is to get one of the 8 cores when they're out and see how far that goes, and I was going to make a call on the 16 core closer to when it is expected. If I go for a 64 core or not in part depends on how I see it scaling from testing the consumer stuff.

i wonder if the threadripper unveiling would be star tr3k themed ._.

 

also another point of contention: would AMD have 16c (or fewer) part(s) for the people who have programs that are apparently licensed by the number of cores in the system...?

most programs that license by core are programs what scale with cores, so there is not a big group of people that need that software and don't want a lot of cores. (AFAIK)

They do

This really will be a monster consumer CPU indeed! The platform for it will be amazing. 

Now new Epyc with 128 cores though, that will be insanity...

each Zen 2 chiplet have 8 cores ._. the substrate only has places for 8 chiplets

(unless dual-socket, so...)

Yeah did cross my mind. Maybe they could re-order chiplets to fit more of them while also scale down the IO die for extra space. Does pose a challenge indeed. Maybe with smaller process node in the future who knows. Or monolithic die haha yeah probably not.

amd does have high clock speed parts, its the 7371, which is a 16 core, which has a all core boost of 3.6 ghz and an 8 core boost of 3.8ghz

this is me guessing but they probably can't shrink the io much, they are already at the highest pin density there is for substrates with epyc 2, so to go further they would probably need to move to an interposer

There is law of diminishing returns. I would imagine that the real problem would be the amount of heat you can transfer from the CPU to the water. You can only get the temperature of the water to the ambient temperature of the room no matter how many rads you put on it unless you pull an Intel and use a chiller. I did see some mild overclocks on a water loop but they were nothing to write home about.
