what does this even mean and why do retards keep using this stupid sounding phrase?

Blackbird (mATX)
Think there'll be 4 or 8-core processors with 8-way SMT when the additional processors come out in Q3 2019? I don't want to drop $400 on a processor just to replace it in 6 months
Why would you want 8-way SMT? What's your use-case?
I like the Blackbird but can't justify spending that money just for the muh open hardware meme. POWER9 doesn't really offer anything in terms of price/performance.
too expensive. not for porrfags.
>Why would you want 8-way SMT? What's your use-case?
Frankly I'd be fine with the 16 threads provided by the current 4-core model; my current desktop's got a laptop Core2 Duo. I'd just want 8-way if I could have it. Really the only intensive things I'd use it for are video transcoding and compiling software, which as far as I understand scale pretty well, so I probably would see an improvement going for 32 threads over 16.
Come to think of it if I'm going for 32-threads I might as well get the 8-core with 4-way SMT for better performance
If you follow that reasoning to its logical conclusion, you will end up with something like a 2950WX (16 cores/32 threads). Just have to ask yourself: is the warm fuzzies provided by running "blob-free" really worth it...
>you will end up with something like a 2950WX
That's not a POWER processor.

I'm not a freetard. Literally the only reason I'm building this is because I've looked forward to something like this coming out since Apple's Intel transition.
Hi OP and others, semi-freetard here. As a daily user what (if any) benefit does this platform offer vs say, linux on x86-86? Genuine question.
Is there no point unless I'm engaging in CPU intensive tasks? What is the idle power consumption? Would I struggle with software availability?
Fair enough, I admit to wanting a Blackbird for much the same reason myself. Benchmarking shows that the benefit of SMT-8 over SMT-4 is not that great for POWER8 at least, so I think maximising actual cores makes sense.

From what I understand about SMT performance gets worse per thread, e.g core 0's 1st thread will perform better than the 2nd, the 2nd better than the 3rd, and so on. So SMT-8 only makes sense for thread counts that aren't already available in SMT-4 processors
