What ever happened to dual processors?

I remember, way back when I first started dabbling in PC building, like back when Pentiums where a new thing, people who wanted uber PCs would have 2 CPUs going on the same motherboard. I guess these days with multi-core / multi-thread CPUs that’s not really necessary anymore. I did a quick google and there are motherboards that take 2 (maybe some that take more?), for servers and stuff. Is it just not really needed for the gamer / enthusiast level? Would there be any benefit to having a system that can run 2 modern CPUs these days for gaming + streaming + content creation + whatever?

Intel has done the same thing in the past. Doesn't matter how it is put together, only what it can do.

Comparing multiple sockets to multiple dies on a substrate actually makes multiple dies on a substrate look good. Don't have to pay for a whole other socket and the real estate on the board to make it happen.

Threadripper/EPYC options easily give a higher core count for the money in pretty much all price brackets, and at the top end Intel actually can't get you as many cores as AMD right this second. If core count is more important than per core performance, they are a clear winner right now. (Though I'm not sure if there are any Intel quad CPU boards for the really high core count chips)

Though none of my vendors will likely offer...

Though none of my vendors will likely offer AMD as an option in the near future anyway.

Smaller businesses perhaps. I suspect more purchases will come from universities and super computer construction then anything else. That is where cost/performance is more important than an existing ecosystem, support, or contract.

Certainly something I would look at if I needed a powerful x86 CPU right now. I think most of anything I might do with a computer would be better served by a powerful GPU for threaded tasks.
 
I do have a older Dell T something work station with dual Xeon's, Giving me 8 cores and 8 threads, I use to use it for storage and running VMware. But my single i7 5820k out performs it, If I needed more cores and threads, I'd probably make the move to Threadripper 1950x. But I don't really need that much Threads.

What happened? Multiple cores on the same die is what happened. As each die process gets to smaller and smaller nanometers, power requirements drop dramatically which reduces heat dramatically.

Now we're stuffing 16 cores on a single die with more performance per core with less power required and less heat generated than the huge multi socket multi CPU motherboards that generated TONS of heat and used hundreds of watts of power.

Enjoy!
