Intel Core Ultra 9 285k 'Arrow Lake' Discussion/News ("15th gen") on LGA-1851

Whatever. Just use high performance power plan if you'll do it. Here's the savefile, just do a capframex recording driving straight from the starting point for 50-60 sec. RT ultra preset (no path tracing), 720p/1080p+DLSS or whatever that makes it CPU bound. Maybe 2-3 runs to see the consistency if you don't mind bothering.


Here you go, hope it helps:

Thank you! The result sadly doesn't look good either indeed. Here's the comparison with my 13950HX ES + 2x24GB 6800cl34 in same scene. I hope Intel and Microsoft(?) will do something about it with BIOS, Windows or whatever else updates because this doesn't look right.

..also what resolution is that pic showing above? one is 4080 one is 4090 and diff. ram speeds too. and "RT Ultra" settings with different graphics cards.

factorio loves cpu cache.

well. it is a nice hatchet job. more#winning for the 13th gen. woohoo

good opportunity to clear out that 'old' 13th/13th-gen-refresh stock?

one more throw away comment: aMD-lake fail? far out. mebbe i get a 14th gen and disable some e-coars. I dont trust these figures entirely.

Just to clarify, this was done with high perf profile?
Or even disabling the e-cores. The 265K being almost 40% slower than an RPL laptop chip points to serious scheduling issues. I wonder if Phoronix will provide similar results. In any case, another disaster for Intel, maybe the hardware is not this bad but the software is not ready,

Arrow lake is cooked, something is clearly very wrong. I think the guesses that it's software related is most likely the case - could be a number of things like: Intel thread software not scheduling correctly, Windows software not scheduling correctly or windows not understanding what it's looking at - the reports of games thinking arrow lake systems have cheats on them is funny, and also possible is bad bios/microcode

First bit of the video "we got a tip that the new chips need power measured in a different way" he then goes into detail on how they test power, I'm sensing that the "tip" is correct.

Would HWinfo etc results therefore be correct or not?

To clarify, it's not really a laptop chip, or at least it's not being run in a laptop. I'm running it in a Z790 board and it's basically a "13900K" with lower clocks (whatever you can get with manual OC, i'm limited by cooling so it's 5.3) and lower mem oc potential (8p8e instead of 8p16e because i'm limited by cooling in stress testing)

I may retest @ DDR5-6000 with XMP timings but the gap is just too huge, yeah.

How interlinked are Lunar Lake and Arrow Lake? Lunar Lake is all about efficiency in the laptop space and has been very well received, particularly because the iGPU is much improved. I can literally play some games at 1080p 60fps on a TDP of 17w.

What I mean is, did Intel going for efficiency on Luna Lake mean that as a by-product of that focus, we ended up with Arrow lake being a more efficient CPU rather than a super fast one?

Or are they developed completely seperately?
Some comments elsewhere implied that ARL and MTL are closer in design in terms of layout - but obviously not cores.

ARL probably has too many tiles, or rather they way it has to access main memory. If the compute tile was joined to the IO die that would make more sense. And unlike AMD, Intel have no need or intention to reuse the same compute tile in server chips.

As the recent spats with Qualcomm show, Lunar Lake is a bit inconsistent where you can either have great performance or great battery life but not both.

Bios fix incoming? :cry:
I'm sure there will be software fixes but most of this does look like a hardware issue.

And he said it was gonna beat Zen 4/5 by 10%+ or something didn't he?

The old rumour monger strategy of "throw enough claims at the wall, until something sticks", but if later that turns to have been rubbish then pretend it need happened!

It's pretty power efficient gaming, this was from playing Hunt Showdown. 36.899W average.

Except it's not right? Take your wattage and divide into the frame rate - what's the fps per watt against other desktop CPUs? Its one thing to have low power draw but if thats comes with atrocious performance then it doesnt matter

The question is if the efficiency comes from not being 100% utilized. Phoronix tested lunar lake and he got terrible gpu results (slower than mtl), Intel patched the issue and performance improved but power consumption increased as a result of the higher utilization.
 
I wonder if Phoronix will provide similar results. In any case, another disaster for Intel, maybe the hardware is not this bad but the software is not ready,
It could be like the AMD performance increase going to 24H2 on Windows 11.

If this is the case it maybe just a matter of waiting for Windows updates or test in Linux and see if there is any difference
