Question 14600k

[gary_murphy101]

Hi guys. Was all set to build a complete new system to go with my 4070 super. 7800x3d...

Today I learned that my existing motherboard supports 14th gen cpus... currently have a 12400

Gigabyte b660m ds3h ddr4. If I was to go with a 14600k, can the board handle it ?. I know the cpu is overclockable and the board is not. I just want a meaty new cpu to help push frames and 1080p in competitive titles.

I understand the 7800x3d and ddr5 will whoop the 14600k but I can save 100s if I can reuse my board and ram ect. Thanks

Hey again,

Rather than open multiple threads regarding mostly the same thing, try and keep it all in one thread. The community will get back to you asap.

Your mobo does support the CPU. However, the board is kinda basic. It has only a 6+1+1 power phase/VRM set up which is not very robust. Whilst technically these boards can use that CPU, the VRM's overheating can cause throttling. Also, with a 14600k, you are wasting money, as your board won't be able to OC it.

You can sell your current system to offset the cost of the new base system.

Edit: Ideally you would want a stronger board, and if you do that, your looking at the same cost as the 7800x3d system.

Setting a reasonable power limit on the 14600k should be fine with that B660 board. Only gaming, not running an all core load.

Still, I prefer the 14500 since it gets most of the way there. 14400 if you want to save a buck.

The motherboard can handle a CPU with a PL1 rating of 125W just fine. So OP can put a 14600K in there and run it at stock settings. And even then, that's if you're running an extended, CPU bound workload. For gaming, the CPU hovers around 50-80W.

Also, with a 14600k, you are wasting money, as your board won't be able to OC it.

This is kind of a moot point anyway since you can't really push the boost clock ceiling that hard anyway. And you shouldn't buy a CPU for its overclocking potential anyways; if you need more performance, buy the part that has more performance.

Besides, the K-suffix processors are still typically the best specc'd SKU. For example, the i5-14600 has the following differences when compared to the K version

• Lower maximum boost clock (100MHz lower for both P and E cores)
• Lower base clock (2.7GHz, compared to 3.5GHz)
• Lower PL1 rating (65W vs 125W), which affects how much the cores can boost in a sustained all-core workload
• Lower PL2 rating (154W vs 181W)

Will this matter for gaming? Probably not as much. But if they happen to dabble in CPU bound workloads, it will make a difference.

This kinda proves the point I was making. The board is bang average. Yes, it can handle the CPU, but that's just about all. Certainly won't make e 'K' suffix processor shine. It's a mismatch. If it were me, I wouldn't want anything potentially holding my CPU back. The comparison here isn't great with a 12900k either.

It's not really about Pl1, and more about PL2, which for this proc is181w. Still, I wouldn't expect it to throttle, or at least too much on only the more basic boards.

• Lower PL2 rating (154W vs 181W)

No, it won't.

Regardless, it's a low end mobo, paired with a mid-to-high range CPU. If remaining with the B660, then the 14600 would be a much better choice. With a Pl2 of 154w, it will be easier on the board.

This is kind of a moot point anyway

Why is it a moot point. You are spending money on a CPU that you can't fully utilise. That doesn't make sense for anyone. Not sure what the price difference would be on the two, prob about 10-20$.

But we're not looking at an i9 class processor in this thread are we?

It's not really about Pl1, and more about PL2, which for this proc is181w. Still, I wouldn't expect it to throttle, or at least too much on only the more basic boards.

And it only happens for the short term. Unless this power draw exceeds the maximum specification of the VRM, then there's no problem as long as the long term average is PL1. And while TechPowerUp claims the i5-14600K's tau is unlimited, even on my Z790 board, it was set to something like 56 seconds even before the BIOS update that includes Intel's specification.

Utilize what? An extra 2-3% higher clock frequencies that I'll have to run CineBench a dozen times to convince myself it was worth the extra cost?

Again, the i5-14600K is better specc'd out the box than the non-K version. Get the K version for that, not the overclocking ability.

Eh, no. You are the only one who has referenced that.,

Whilst that seems to be trivial to you, for others it's the exact reason they buy a 'k' suffix CPU.

Whilst binning might play a part, there will be practically zero difference in the two(apart from price) in almost every bench mark or game or load. So why pay extra?

Here's Tom's mini review: https://www.tomshardware.com/pc-com...lightly-slower-but-a-lot-more-power-efficient Edited

5%! At best! I think that translates to roughly 5% performance increase for an additional 10% in cost. Way to go!

Either way, I think they OP has plenty of info to go on. Nuff said

I never said anything about an i9 class processor. 🤔

So given your next point, they're even more dumb to buy a K suffix processor because that push isn't going to make their investment worthwhile.

Sure, we'll leave it at that.

You will not get much extra performance out of a 14500 or 14600K or 14700K. The 12400 is slower on paper but in practise it's not that slow compared to the others.

If you bought a z790 motherboard and a 14700K, you still would not get much extra performance.

Just letting you know how it is, because if you wanted to you certainly could buy a 14500 and enjoy a small boost. That's about as good a CPU as you can run, and it's not bad at all.

As for the 7800X3D, it would still not be a huge improvement. Nothing i would call a whooping. It's a stronger CPU and if you switch to AM5, you will have new CPUs coming out in a couple of years.
The 3d cache is the biggestdeal, but that's only when games make use of it. If they don't, the 7800X3D and 14500 are about tied. The 7800X3D slightly ahead.

Maybe the improvement is enough for you. What refresh rate are you targeting?
4070 Super /w 12th gen CPU is enough to fly at 1080p unless you want really extreme frames.

A 14600K will get you about a 25% performance increase from your current 12400, and while thats pretty good, its also not necessarily something that you'll notice very heavily. I would say save up for an AM5 upgrade at the end of the year to get yourself a nice upgrade, and a better upgrade path. Then sell your old parts to recoup some of the cost.

The article you linked for the B660's is using an I9 12900k!
