As an outsider to 'enterprise-grade' computing, I'm curious about situations where a high number of cores in a single processor would be superior to multiple processors with the same total energy draw sitting on a single motherboard? I can understand HPC applications where the high-speed interconnect on the chip would make a big difference. But in business applications where the cores are dedicated to running indepen…

If your cores are independent, you're blessed and can scale just by adding more cheap servers.

I just recently replaced my old i7 920 in the homeserver with an AMD Ryzen 5 2600. Really like it so far. Price / performance is great. This is my first AMD since probably ever.... The two things I don't like is that their CPUs are pin based. It seemed kind of old fashioned after Intel CPUs. But this is really a minor thing. The other issue is memory compatibility is a bit finicky. Maybe it has to do with the CPU bei…

> don't like is that their CPUs are pin based To me that's a win. If a CPU pin is bent it's typically fairly easy to straighten it. Fixing a bent pin a socket is a massive pain. But it's much easier to protect socket pins with the cover. So there are pros and cons either way.

Massive pain is an undestatement. Fixing a socket pin with a that small of a package size and 1151 pins is nearly impossible.

Good luck. You better have a loop or magnifier.

I buy Intel Mobile CPU boards for exactly this reason. Pins. I have not bent a single one in years. The Notebook CPU's are so thermally efficient it is a real selling point to me.

Which one of these companies does at better job with free/libre software? I've always had a soft spot for AMD because it's the underdog, but I want to make sure that they are free, too.

They're about the same. Both contribute to linux. Intel's GPU drivers are more complete and open, but their GPUs are not in the same league as AMDs. AMD has open and closed source versions of their driver and are moving more towards the open version (which is already very good). Both companies have closed-source initial boot and AMT-like tech with potential backdoors built into their CPUs.

It's awesome that TR2 will be a drop in replacement on existing motherboards! Props to AMD for delivering real value to consumers.

I recall reading that the thread ripper 2 is supposed to use more power so early motherboards with that socket my not be able to handle it. Just something to keep in mind. Regardless damn good on AMD.

That’s only the 32core And perhaps 24core TR. the 8-16 will probably be lower than current due to node shrink.

I can see two answers to that.

First is that a single-socket motherboard is still a simpler design to produce with all the advantages that entails.

Second is that you’re allowed to stick two of these on a two-socket board for CPU-bound loads. Better density for when you have the thermal capacity to spare.

Are you talking about contributions to OSS in general, or specifically around processors?

In general, as a company.

If the answer turned out to be Intel, would you overlook the misleading 28-core demo the article discusses?

Yeah, though it's not the best thing to have on the resume. That's for sure.

Earlier quoted context omitted.

I'm into VM abuse, so for me more cores would be a no brainer... Sadly for AMD that would be IF i needed a new machine. My 2012 Core i7 still seems to be enough for my needs. (Except the GPU, that I changed recently.)

I feel you there, I was using a i5 2500 since it came out until last year march when I switched to ryzen. A very good CPU indeed.

At this time the only reason I'd upgrade would be to go from 32 G ram to 64. 32 is barely enough if i happen to need a couple VMs up and the usual 100 tabs of docs in the browser :(

True, though it is much easier to damage a pin-based CPU in the first place.

Usually, I'm very careful with the CPU, more than the motherboard, so I think that balances out.
