I am doing some research on there 2 beauties (yeah sad right) but I can't completely get around them -

Apparently they can both OC to a similar level. Ok, so get the 8600K.

But apparently the 8600K does not have hyperthreading, whereas the 8700K does.

1) What does that mean in real world performance?

2) Did intel fix the 8000 series CPU that caused "up to" 30% speed bump applied to all its CPUs not so long ago? Don't want to pay money to upgrade and then take an instant 30% speed bump.

The speed bump I assume you're talking about is the Spectre vulnerbalities.

No these won't be fixed in silicon for a few years yet.

The current CPU you have if you have patched windows and the BIOS would have already been hit by the performance.

the 30% is also for very specific, often datcentre based workloads

CPU: AMD 5900x | RAM: GSKILL Trident Z Neo RGB F4-3600C16D-32GTZNC-32-GB | MB: Asus X570-E | GFX: EVGA FTW3 Ultra RTX 3080Ti| Monitor: LG 27GL850-B 2560x1440

8600K = i5 .. so 6 cores and no hyperthreading .. 8700K = i7 .. 6 cores and hyperthreading so 12 threads

Is this purely for gaming ? or are you looking for a balanced gaming and productivity solution ?

If its only gaming then the 8600K should be fine .. as even with a $1000+ GPU there is no CPU bottleneck. If its more than just gaming then the extra threads on the 8700K would have a benefit but the new AMD Ryzen 2600X should be in the mix too.

Not sure what you mean by 30% speed bump .. is this an increase or decrease you have heard about .. in real world most users are only seeing 2~5% max drop - see here - https://www.youtube.com/watch?v=_qZksorJAuY

Mainly for productivity.

Maybe I'll read up more about this hyperthreading vs no HT ...

Given a decent motherboard both can clock to 5GHz, although this might be less nowadays due to the binning of 8086k.

Hyperthreading is a doubling of logical threads for each physical core.

6 threads on the 8600k vs 12 threads on the 8700k

You'll get an almost doubling of performance in multithreaded applications (practically not always, and depends on what you are doing) eg. video transcoding, file compression etc.

Gaming will benefit from less stuttering and higher minimum frames on the i7.

If you are doing things that benefit from lots of cores then I honestly would take a look at AMD 2700x for a similar price as 8700k. It has 8 cores and 16 threads and can clock at 4GHz.

If majority gaming then Intel.

Make sure you're getting somewhere around 3200Mhz CL14 or 16 RAM as both platforms benefit from it.
