New PC - Video editing + some gaming (£2000?)

It depends on what reviews are being referred to, I guess, but my impression is that Arrow Lake is much more competitive than the 13th-14th gen CPUs were against AMD.

For example: in TPU's power efficiency numbers, the 265K is on a par with the 9900X in multithreaded and way ahead on single thread (though I think the higher single/lightly threaded efficiency would have been influenced by the lower idle numbers).

The 7950X3D smashes them all out of the park with multithreaded efficiency, but that's not new, since select Zen 4 CPUs have always been way up there (I used to really like the 7900 non-X for that reason).

You mentioned this before for the intel CPU:

"Air cooling the Intel CPUs (or any higher-end CPU really) will likely require some management of the power limits and the fan curves to achieve the comfort you're after."

I'm not going to be the one building it, I'll be asking OCUK to do it for me - so does this matter and be something that I should take into account when picking CPU?

I think I meant the 285K versus the 265K?

The reason why is because I consider around 150 watts to the maximum you really want to run a decent dual fan tower cooler before the noise is a problem and while the 265K is recorded as 155 (fine), the 285K is 235. For a gamer it isn't a big deal because games don't run a CPU at 100%, but for long-run multithreaded stuff you do have the CPU pegged at 100% for long periods.

The other issue is that when the turbo kicks in for short periods, it can cause issues with the fan cycling, brrrrrRRRRRR, which is easily annoying if you're just web browsing, opening an application, or whatever.

In terms of: does it matter for you? It might, it depends on how much effort OCUK would put into customising the fan curve, since I don't know if that's something they would worry about in their testing, or if they'd just consider "CPU not throttling" to be good enough. It does depend on personal preference too, since not everyone cares about desktop noise.

Ah okay, so maybe not the same issue with the 265k.

Googling for the 265k reviews doesn't give much enthusiasm vs going AMD :cry:

Yeah, they don't :D

What I wrote applies the same for any high-end CPU, which is one of the reasons I prefer stepping down from the top-spec CPUs, because they're usually a bit easier to manage and don't push the power use so far.

AMD do have eco mode which can be handy and you can customise the power limits on Intel CPUs too, but that would depend on how much someone wants to air cool versus water and if power efficiency is a priority.

I'm very much a novice with computer building so even with someone else putting it together I'd prefer air cooling over water.

I'm tempted to just go for the 7950x.

:cry: I could give you simpler advice, but I don't want you to buy one of those with a peerless assassin and then say "OMGZ every time I click something I hear brrrrrrRRRRRRRR and it is driving me nuts!!!!!!" or: "when I start to render my PC sounds like a jet plane, help!!!!".

To be fair I actually think my current PC is probably quite loud when rendering.

But I've never really thought about it or heard louder/quieter ones so I don't have anything to benchmark :)

Yeah, that's why it is hard to give advice and make recommendations, because noise tolerance is always a personal thing, but I definitely consider if the CPU uses more than 150 watts you're borderline on noise tolerance with air cooling there. Typically you'll find that PCs will use water cooling (most commonly: a 360mm AIO) on an Intel i7, i9 or Ryzen 9 CPU. Where they use air cooling, there's often some kind of power limiting going on to make it more comfortable.

I appreciate the help either way - I might be back tomorrow with more confusion!
