Can you put two CPU's into one unit?

[TechyWinkie]

Might be a dumb, boomer question, but it got me thinking. If motherboards can support 2 identical GPU's, could they also support 2 identical CPU's? I'm bored so I'm just wondering what the future of PC building would be like.

you can right now, but they are generally reserved for server deployments, there is next to no real benefit for a consumer to use a dual socket motherboard.

Heck, this has been done since the '90's.

If games or software require a lot of CPU juice, there would be a demand for dual socket mobo's right?

I meant PC's but yeah I guess it was sort of a stupid question .-.

Not sure what you exactly mean by that. 

But some boards do have dual sockets. 

Though the cpu does need to support dual socket as well. And they have to be the same cpu and those boards are usually server boards.

If the workload supports dual cpu's then yes. 

Most if not all games don't though.

i doubt it, single CPUs have already progressed so much that a single CPU can do more than what dual sockets could do from a few years ago. 

 

Games rarely use Crossfire or SLI as is, so i dont see devs supporting mutliple CPUs any time soon.

Can't be a stupid question if industry has already thought of it and is doing it.

Thank you for enlightening me. I'm genuinely curious of how games would perform if they require dual cpu's.

Ummm, lets use all 64 cores on the threadripper to game before we think about 2 of them

Yeah I guess that does make a lot of sense. Thank you for answering my question though!

Now just imagine the fireball that would be 2 9900KS's in one case.

I mean they don't and can't utilize dual cpu's. 

And I don't see why they would, games don't need the extra horse power.

Except they can utilize dual CPU's, just not well. I'd be willing to bet if I found an extra cooler for my E5450, all 8 threads would be active.

 

The OS handles the CPU's, it 2x quad cores appears as an 8 core.

Ah they games can utilize two cpu's? 

Well I wasn't aware of that lol.

Yea I'm aware of that just didn't know games actually support dual cpu's.

The OS provides a layer of abstraction. That'd be like a game not running on AMD CPU's, despite having the instructions. 

 

Doesn't mean it'll scale well, most dual socket setups have significant latency between sockets. Similar to Ryzen's CCX vs CCD latencies.

 

Keep in mind, Ryzen is essentially 1/2/4 CPU's in one package. Infinity fabric ties it together. In Intel, that's QPI. Older yet, the north bridge handled CPU's entirely.

the dual (or quad) socket boards are usually just for server space and specially in VM environment. Having lots of core in small factor saves a lot of space. Like a Xeon 9282 in a dual socket gives you for a single board 112 core and 224 threads. That's a lot of VM in a single U2/U3 (minus the 4 for the host maybe 40-50 VM's, perfect for a small company). The games that leverage full multithreading are very rare. Not everything is possible to be multithreaded and i understand them as a developper / IT guy.
