As the title states.

I am contemplating a upgrade.

The 8700k runs a bit hot to my liking. It seems the thermal issue has been sorted with the 9700k soldering? The performance difference between the two chips seem minute. Are they on par clock for clock? My other option is to delid the 8700k for (possible) better temps, but loose warranty.

Any inputs would be highly appreciated.

Kind regards,
 
I vote for tuneup before upgrade:
Delid CPU
Set CPU voltages manually (overclock)
Adjust RAM timings manually

Keep your 8700K and delid it. 9700K won't be a massive upgrade.
 
I was wondering if there is any performance difference? I have not seen a review where they go up against each on the same oc.. Choices choices

Check out hardware unboxed on youtube, Steve has some of the more detailed reviews & benchmarks. There should be a video for the 9900K vs 8700K.

Yes and no. Yes, you'll see a gain in performance but it's not worth the cost. The amount you sell your 8700K for second hand and then buying a 9700K makes it a small gain for a much larger expense. I'm not saying you won't see an increase in speed, I'm saying you'd be wasting your money.

If I had one thing to upgrade that would increase your gains is to get a really good Z390 board, like the Auros Master, as the VRMs and overclocking will allow your 8700K to reach higher clocks.

Here, listen to what Buildzoid has to say

yeah what he said.. decent motherboard and delid that 8700k CPU
 
I have a MSI tomahawk at the moment. As far as I can read it is a mid/low end motherboard.

I am not looking for insane speeds. 5.1 to 5.2 should be fine for me.
 
Any suggestions of people/places that do delids?

I know about Rebeltech and Omit Computers so far. Need to shop around a bit.
 
I think Rebel Tech would be your best bet (if you purchase the CPU from them). Apparently, they continue to honour the warranty even after delidding the CPU.
 
Nope was not purchased from them. Did not realize the delid thing is so pricey :( Might as well get the 9700k

Just know that if your motherboards VRMs are weak, even upgrading to a 9600K won't increase your performance that much.

What happened is that Intel basically increased the TDP wattage limit at high speeds in an attempt to increase performance over the 8th gen. This puts strain on cooling, obviously, but also put strain on the VRMs since the power draw is the same as just overclocking your current CPU.

What motherboard do you currently have?
 
8700k isn't bad at all, the jump if you're looking at gaming benchmarks is not a super insane gap and that's without doing the OC I have. Did my delid with Rebeltech and would definitely recommend them and add honourable mention lol

Looks like it’s a 4+1 with a doubler to give you an 8+2.

Should be good. How has your 8700K managed on it? Have you hit 5.2ghz?

The 9700K runs pretty hot, even with an AIO cooler.
I recommend the Gamers Nexus review for a good comparison on temps.
From the delid video they did it's going to be harder (read: easier to break) the 9700K with the solder than it will be to improve on the 8700K's TIM.

Last thing you want is to buy the 9700K, be disapointed by thermals, have it delidded (and breaking) and then being massively disappointed.
 
I only started fiddling yesterday. 5ghz seemed stable @ 1.26
Booted 5.2ghz @ 1.28. Started intel burn test and it blue screened. So I have no idea what to expect.

@Munk Thanks! I also saw this article. Ok my mind has been made. Going for delid. Thanks everyone for your inputs :)

@JollyJamma where did you get the tech specs for the vrms? On the website? I have no idea what you said there, but it sounds acceptable?
 
with the delid you could try 1.35v etc, it's possible that will prevent the bluescreen depending on how good your silicone lotto was

The motherboard VRM is 8+2 phases. It uses the same UPI uP9508Q PWM controller we found on the Gaming Pro Carbon, which is rated for a maximum of 3+2 phases, but it seems that it's in a 4+1 phase mode somehow. The motherboard uses new UBIQ MOSFETs for the high-side and low-side MOSFETs. The QN3107 and QN3103 are used as high-side and low-side MOSFETs, I estimate they can do around 25A of output, in the end, each, but they have insanely high ratings over 100A for burst operation. We will see how they do in the thermal testing section. I also found that each set of two phases had one driver, so they are doubling up inductors and MOSFETs for each PWM phase to get 8 phases. The memory VRM uses one phase and a real phase doubler for two phases in a two low one high-side MOSFET configuration. The uP1961 is used as the doubler and dual driver. We also found a Richtek RT9553B high accurate current/voltage sensing and protection IC near the PWM controller, which might be how MSI is getting one extra phase-out of the CPU side (maybe it helps combine two real phases into one).

Not bad but could be better.
 
Thanks!

What is average voltage for 5ghz? With no VTX?

I had to re learn overclocking. Last platform I tried with was Sandy bridge lol

Rather exhaust all overclocking results to determine if you have enough processing power with the 8700K before you take the plunge with the 9700K.

Great stuff. Will certainly do thanks! We need a Coffee Club rofl to exchange results etc. Will have to join an international one

Looking at this thread, I call it a waste of time, effort and money to "upgrade" to a 9700K.
You could "upgrade" by just moving to 1440P or 4K which puts more strain on the GPU.
