Is the i5-9600k a risk?

[Scottmt80]

I'm weighing my options for a cpu upgrade, currently have the i5-2500k (4.2OC) Primary uses is Gaming. I was going to just grab the i5-9600k because it seems to be the best value at my price point. But its so new, so unknown, they're very few reviews out and a lot of talk about 9th gen running hot along with Z390 mobo power output issues.

On the other hand we have the i5-8600k, this cpu is proven, I can find a wealth of info on mobo combos and overclocking. i.e. I know what im getting into. I suppose Z370 vs Z390 is another thing to consider. The wifi upgrade doesn't matter to me.

So, would you go with the proven i5-8600k or the potentially more powerful, yet unproven i5-9600k. Future proofing is important to me. I don't want to have to buy another cpu for 7-8 years. Shout out to my i5-2500k, Love you baby.

I feel like this question might be a little ridiculous and I should just get the 9600 but wanted to hear others weigh in. Thank you.

The i5-9600k is able to sustain a minimum of 3.7Ghz using all 6 threads with a TDP of 95 watts.

The "controversy" is when people overclock and have all 6 threads at 4.6Ghz and wonder why the TDP is much higher than 95 watts.

The Turbo feature of the cpu is able to run at a number of frequencies (see link below) when not many threads are used or on all threads for a short duration.

The chart shows the i5-9600k being a 200-300 megahertz upgrade depending on how many cores are being used.

the thing is, whilst it is a 95W electrical CPU, it is thermally to be treated as a 130W processor, so having what you think to be a beefy cooler covering maybe 150W, is only just over the recommended 130W.

Agreed.

Think of 95 watts as the minimum thermal dissipation your cpu cooler has to do not the recommended.

TDP is not electrical CPU power. It is Thermal Design Power and is a guideline for the amount of thermal heat (in Power/Watts) that will be dissipated and is supposed to be a reference for cooling power.

Why is there such confusion even from Intel on this?

OK, it still needs a 130W minimum cooling system.

8000 series has a supply issue, and production has been cut partly in favor of 9000 series among other reasons. Prices are over MSRP.
I think the 9600K will be a better chip than the 8600K primarily due to a solder like the 2nd gen that was removed from 3rd to 8th gen.

Z370 will need updated bios for 9000 line, and as for Z390 power issues I had only noticed the ASUS ROG with a 8 phase power delivery being 4 phase. Something questionable on a premium line. Wifi works with either, just cant use a CNVI reduced cost (supposedly) card on Z370 as it lacks the built in part that is on the Z390. Z370 is also missing native usb 3.1 gen2 which can be added with a chip.

Can always wait a little for more reviews no need to retire the 2500K right now unless it died.
