Considering that all is going to multithreading and 4 cores is already standard then I simply see no reason to push next 2 core cpu into gamers/enthusiasts market. 4 cores is minimum for a gaming PC and it's what is scalling the best with most games. 2 cores are much slower in many titles regardless if there is HT or not. HT adds 0-50% performance but here are applications which are performing worse with HT enabled ( not many of them ). Simply I wish to see 4, 4+HT, 6, 6+HT, 8, 8+HT, 12, 12+HT, 16 and 16+HT versions of ZEN on the desktop market ... somehow I doubt in all that above 8 cores but I just wish to play with something like 16c+HT ZEN if it performs as leaks are saying.
Also rumours say that we will see ZEN in the middle of Dec... at the same time that it will be presented at CES in Jan. Hard to say what is true and if we will see it before middle of Jan in stores.
Could the lower 8x slot be used instead if you wanted to go full length?

How radical does something have to be to call it a novel new idea? On the X2 example above, was it that surprising? Multi-socket systems were around and very affordable at the time. Moving two cores together is a natural evolution, and we've been doing more of the same, by moving in the cache into CPU, moving the memory controller in to CPU, moving GPU into CPU (you know what I mean) and more and more IO is getting moved into the CPU. SOC are also widely available.
GPUs and "deep learning" seems to be a trend area at the moment, but is it that different from X86? Quantum computing would certainly rewrite the rule books about a lot of things, but is still out of reach.
Even sticking to conventional computers, I've wondered if CPUs themselves could benefit from going more async internally. That is, why fixed clocks? If a block can do something faster, let it. Taken to an extreme, the concept of clock as we know it may need to be removed.
Maybe less of a forward idea, analog computers are a real thing if you look far enough in history. It doesn't have to be digital. How to make use of it in the modern world, is another matter...
Well the temporary dual E5-2670 rig is up and running. The photo isn't the best but if I use the flash its even worse. Due to the PCI-e x16 slot being positioned directly in front of the CPU1 memory, only a mini GPU will fit (roughly 7.5" will fit). But, if I keep it for long, the best I would put in it would be a GTX 1070 anyway, so, no problem. I have my mini GTX 1060 sitting in there to get it up and running. Had Zen been out, I would have built one of them, but it isn't.
The only case I can think of right now where HT gave 50% boost was in an old distributed computing project called Life Mapper. It doesn't exist any more. I've never seen above 50% boost so wonder if that is some practical limit.
For modern "HT friendly" software I typically see 30-40% boost.
Getting async multithreaded jobs right in software is already hard, and you want it to be implemented in a general purpose CPU? Might take a while
Spare resources for HT will be between 0 and <approaching-50> percent. It will never be greater than 50%, because then your "normal" and "HT" threads will have semantically switched places. I'm too lazy to write out the math
