Hyperthreading vs a physical core.

So lets say an i5 (7600K) vs i7 (7700K). Both at same speed. Just what is the difference. I remember when I bought my i5 I was told by many that for gaming don't get an i7, get the i5. But what is the case now? Me personally I do quite a bit of video editing and graphical things now, so I'm just wondering how much of a difference is 8 threads over 4 threads? Is it twice as fast in rendering? or only 5% extra speed? Just how does it work out. Thanks.

Yeah I'm excited about upgrading from my 4690K to either a hyperthreaded 6 core i7 or 8 core Ryzen 7.
The odd thing is... I always thought my GPU would be the first thing to upgrade. (As I haven't really upgraded in ages going from 390x -> 480 -> 1060. (Basically all perform the same). but god damn the cost of high end GPU's now is just stomach turning. Plus I'm gaming much less these days. Doing more content creation for a few groups I manage. so oddly the CPU might be first to change.

This is enormous speculation but do you think for Intels 9th gen. They will up to 8 cores 16 threads to match Ryzen? or will we be sticking with 6C/12T for a while for mainstream i7's? I guess it depends what AMD do next. If they start knocking on Intels door in terms of IPC and clock speed then Intel will have to match them in core count.

I hope we see 8 core / 16 threads as kind of standard at the i7 type position - after being on 4 core / 8 thread for so long 6 core / 12 thread is kind of underwhelming as an upgrade.

I'm going to say it entirely depends on AMD now. As it stand Intel don't need to do 8 cores because they have the clock and IPC win. So most gamers will still be buying Intel. However if AMD get close to Intel clock and IPC then Intel will simply have to match them core for core. Adding cores to a CPU is a real cost per CPU that Intel don't want to incur. That said, I really don't think Ryzen will be able to hit that Intel calculation speed. I think Intel know that. So are just doing "enough" to stop gamers buying Ryzen (which that have been doing of late).

A bit of an odd one but what will signify a move from "lake" naming schemes? Is it tied to node size? or just a marketing thing.

It's not genius, it's cheap. It introduces a load of communication overhead between the dies. Notable that Intel did two dies stuck together in the olden days, at least as far back as the q6600.

Thats mad, it's a lossless communication system. quite literally "perfect". From what I have seen.
