Multiple different cpus in one system?

[Max_s]

Hey guys, I am wanting to build a pc that will be able to game excellently, as well as run complex engineering programs that more cpu threads will speed up the time to complete the simulations and edit/render the occasional 4k gopro footage. Is it possible to have an intel i9 9900k and a ryzen threadripper 3990x in the same system?

I am wanting the ability for the i9 to take all the single core gaming load while the TR takes the streaming/ video encoding, or background rendering load, or some that can work similar to what I have said.

Can anyone help?

Sorry for bad grammar/spelling etc. Typing this at 4 am. Just ask if you need me to clear anything up, thanks

a 3950X is going to be a nice mix. a threadripper 3rd gen chip doesn't lose much to 9900K when gaming especially as resolutions go up

No. They use different sockets and chipsets, so that's not possible. There are dual sockets boards (typically for servers) but they require the same type/manufacturer of CPU for both sockets. Even with a dual socket board you can't exactly control which CPU gets to process a task so it's not like you could limit games to a specific CPU that easily.

 

You could build two systems and use one or the other depending on your needs but you're probably better of using a single system with a CPU that is either a good compromise between both use cases or more optimized towards your main use case. It's not like a 3950X can't game, it may just be slightly slower than the 9900K and the 9900K can also do productivity but maybe not as fast as the 3950X.

So are you suggesting just taking the one threadripper? I'm just wondering about the up to 5ghz on the i9 and if the clock speed of the 3950x TR would be future proof for the next while

clock speed doesn't matter. there is no future proof.

Oh ok thanks. With two separate systems, is it possible to have them both connected to a single storage system, and same keyboard and mouse etc. and having them be able to output to a single screen simultaneously/ be able to switch between pc's with ease, like almost alt+tab? So it can behave roughly like a single computer. I would still have to run programs on the respective computer, is that possible or am I just dreaming at this point?

In a usable manner like you're thinking, that is very much a dream scenario.

I have 3970X and 7980XE systems I have on a KVM connected to the same monitor and peripherals, both mapped to the same NAS storage servers on my network, but they're far from being a single entity.  I can switch pretty quickly by tapping scroll lock twice.

Single core perfomance difference of 9900k and 3950x is not that huge, 10% at best.

Really not worth it to build another system just for that purpose.

Oh ok, would you say it is practical in my case? I'm planning to have everything in a custom designed and built case to keep everything clean looking and take up slightly less room. Also, could I potentially have my video output from my gaming system go directly to the workstation to encode and stream to youtube or twitch etc? (Sorry I'm pretty new and inexperienced to pc building)

Oh ok thanks, If I were to go for the single system with the TR 3950x, is it possible to have 2 different gpus? For example a 2080ti for gaming and a titan x or quatro for work? Or will I have to pick only one that will fit for best of both worlds?

[SupaKomputa]

Yeah ofcourse, as many as the PCI-E slots.

You can use GTX for gaming and quadro for work.

Of have them both doing the same job, if the program supports multi gpu processing.

The 3950X is a mainstream (non-threadripper) AM4 chip. It's has 16 core 32 threads, but limited PCIe connectivity. Fine for most things, but if you're going dual GPU and plan to use a bunch of NVMe storage, you may want to consider the 3960X instead.

 

You can do that with GPUs, but you might be overthinking it. What programs are we talking exactly?

Sweet, but is there a way to change what gpu gets used?

I have no idea at the moment, but as I can afford any of these options, I'd rather be well over prepared. Also with your previous reply on having 2 systems that you can change between would you say it is practical in my case? I'm planning to have everything in a custom designed and built case to keep everything clean looking and take up slightly less room. Also, could I potentially have my video output from my gaming system go directly to the workstation to encode and stream to youtube or twitch etc?

It's great for me because I like having 3 operating systems (I also have a mac connected to the same KVM), but not to great for saving space. It does sound like you can do what you need with a single system though. I always recommend that if it can be done (unless we're talking capture systems). Having an unlimited budget is one thing, spending unnecessarily is another.

 

Perhaps start out with a 2080 Ti (or later card depending on your time frame) and then add the Quadro if you find it necessary. PC building is one of those things where buying all the equipment before you know you need it can end up being to your detriment. Starting out with a single GPU and scaling up from there can be done at any time. You just need to chose a PSU with enough power to accommodate the future need and plan it into your case design.

That one's outside my area of expertise. I'm sure it can be done with a capture card, but I've never done it.
