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

[McCarthy]

Also, reviewers only test clean installs with modded windows to remove all bloat. Meanwhile when I buy a CPU it goes into a system with a 2 year old install filled with apps and bloat. It's one of the reasons I won't buy an 8 core CPU

I wonder how much of a hit, if any that’s causing?

I’ve always been under the impression that a clean install is a must and can cause all kinds of issues. Obviously yours must be fine.

Hi all new here, be kind to me

So i saw your mb with the Aquacomputer Cuplex Kryos Next + Vision on a LGA1851 i am very curious how that cpu block performs do you have any data ie which cpu (265k or 285k) and temps idle and 100% load?
Reason i am asking is that the Cuplex Kryos is not 100% flat it is convex which was good on LGA1700 but on the LGA1851 it isn't i think correct?. This from different forum threads speaking about this cpu block + LGA1851. Some lapped their Cuplex cpu block for better temps. Just wondering if lapping is worth the hassle tho....

Did you lapped yours? Or did you use just the stock cpu block? Before i even attempt at lapping this block (which i already ordered so no going back heard about this convex thing after i ordered it).
In any case i am very curious in your temps and if you had a chance to try out different cpu blocks on a LGA1851 that would be awesome do share your differences in temps with these blocks.

Also to any one: Is the 285k worth it over the 265k? I need this for my secondary system for workstation and secondary gaming rig. Usage browsing, multitasking, video rendering/editing (occasionally) and at times gaming at 1440p or 4k. But the reason i may go with 285k is "Longevity" for years to come more cores the better right? I look at a minimum of 5 years usage so maybe an investment in a higher core count is preffered?

I've not seen any issues which I have noticed but I know its not as good as the Optimius block I have on the Apex. I can run R23 for 10 mins and report back if that helps? If so do you have any specific settings in mind?

The 265K will have better latency than the 285K from some of the posts on OCN I have been reading not by much but there is a difference. In terms of the better option, if you have a workload which requires the extra bit of M/T performance then a 265K may be the better option.

Thank you for the reply,

Yeah if you can share your temps with the Cuplex Kryos Vision cpu block (if you can obviously) with 100% cpu load example R23 sure it would be of great help to post the temps. Can you tell if your 265k or 285k is overclocked or just stock when posting temps?
Yes the Optimus block is a better block but very hard to come by and to expensive in EU.
How would you rate the performance of the Cuplex Kryos Vision block are you content with the temps and how much in celcius does the Optimus outperforms the Cuplex 3c, 5c?

its worth it for gaming ??

 

[RSR]

Not really, as it doesn't seem to get very hot, even CP, which is CPU heavy it's pretty impressive.

Here are a few 1080P runs, including metrics with a stock CPU and mild OC

Mild OC

Just wanted to report something unrelated. I removed an SSD, the HBA and both HDDs. Now my setup has 2 SATA and 2 NVME SSDs in total. The 265k system now idles at 50 Watt with monitors asleep, 55 Watt with 2 monitors (both 4k set to 60Hz) enabled connected both to the iGPU and 65 Watt with 2 monitors (both 4k set to 60Hz) connected to the iGPU and 1 4k monitor (4k set to 240Hz) connected to the RTX 4090 (all 3 monitors being active). These are very good results in my opinion.

Again if anyone wants to reproduce this, here are my specs:
Core Ultra 7 265k
ASRock Phantom Gaming Z890 Lightning WiFi
64GB G.Skill Trident Z5 RGB silber DDR5-6400 DIMM CL32 Dual Kit F5-6400J3239G32GX2-TZ5RS (set to 6400 MHz XMP profile in BIOS)
RTX 4090
Storage:
Transcend MTE220S SSD 2TB
Samsung 990 Pro 4TB
Samsung 870 EVO 4TB
Crucial MX500 2TB
Corsair RM850x (2021) power supply
2x Fractal Design Dynamic X2 GP-18 PWM 180mm fans
2x Phanteks T30-120 fans
1x Fractal Design Dynamic X2 GP-14 PWM 140mm fan
Roland Bridge Cast Audio Interface
Mouse, keyboard, webcam also connected

I will test this setup with the X670e Steel Legend Motherboard and 9800x3d and basically see if populating a second PCIe Slot is going to maybe make a bigger difference in power consumption than on an equivalent Intel system. If yes then the idle power figure might be closer than the previous findings.

Awesome man many thanks for the report.

This is what i was looking for one for stock settings and one for a mild overclock on the 285k.
Going for a similar build 9000mhz CUDIMM kit but i expect to be stable at 8800mhz at least i hope so in a Asrock Z890i Nova ITX.
Already preparing my Lian Li A3 matx case for watercooling and additional DDR5 ram cooler.
Will post my findings here incl temps, OC etc for the ones interested.

PS: how much gains would the Optimus cpu block would have got you in celcius 5c? No need for testing just from your expected viewpoint.

Thanks again i appreciate your help RSR

Just put my order in for the 265k as it dropped to under £350. Looking to see what motherboard and RAM to grab now, definitely keen on the 8000mhz 2x24GB kit mentioned in this thread a few pages back and then I'll consider which motherboard too.

In terms of cooling, I have both a 240mm AIO and a D15s available to use - what would everyone recommend here? Cooling performance between a 240mm AIO has always been comparable to the D15s - but I could always grab a 280 or 360mm AIO if the improvements to heat/performance were worth it. I've always wanted to try the Arctic Liquid Freezer AIOs!

Looking forward to the next gen intel mini pcs, hopefully with thunderbolt 5 support.

I wish they sorted AMDs mess with USB 4 reliability and performance and added better support for thunderbolt 4 and beyond.

It is weird because USB4 on my Lenovo Legion Go so far has been pretty good, aside from maybe some issues with eGPU enclosures but that might an enclosure / other drivers problem rather than an AMD issue. But on some other AMD setups USB4 has been an inconsistent experience with stuff like late detection of devices, etc. being an issue.

Glad to hear not the only one, I prefer AMD due to more pcie lanes, but its a nightmare sometimes backing up and cloning drives or copying large files over to nvme enclosures with disconnections and un-reliable usb speeds, 10gbps or above far worse. This is with updating the nvme firmware's with latest firmware.

At least its not done often, still tempted to go back to Intel just for thunderbolt 4/5 where everything just worked.

I've not had disconnections, or nothing regular that I remember anyhow, but sometimes if a device is plugged in on booting up it takes an age to be detected or won't be detected until you unplug it and plug it back in again which is annoying.

Very nice.

I'd say ~5c difference I am seeing from the Optimus block

It depends man i was in the same boat as you.

If you use a good case then a D15 should be good on a 265k stock (intel default setting) but...the moment you start using within the bios things like "performance" and with a higher PL1 and PL2 setting or do a manual OC then these things become pretty hot as ive seen in reviews and user feedback. Arrow Lake loves high speed CUDIMM (there are rather big gains at the sweet spot of around 8000 to 8800mhz) if that is what you want then CUDIMM is the way with if you can a 2 dimm slot mb there is one out there for a decent price but it's ITX ie The Asrock Z890i Nova.

I wanted to use a D15s it can fit inside a Lian Li A3 matx however the case is small. So i checked for a proper AIO 360 i then decided screw it due to the sound of the fans on those things at higher loads. And im not new to custom watercooling i have everything i need except for a cpu block which i already ordered. If you intent on using higher performance within the BIOS or do a manual OC then i would def go with a good 360 or 480 AIO if your case can handle it.

Question in regards of the Intel 265k or Intel 285k...

I am torn between these 2 cpu's on the one hand i need to make this system last at least 5+ years its my secondary pc as a workstation usage = browsing, sometimes video editing, work related stuff (nothing major fancy), secondary gaming rig 1440p mainly. My opinion 285k should have that extra power to last me for some time. I hate sluggish performance when i have multiple tabs open and do some occaisonally video edits or work on video or use other programs in the background.
But then again so can the 265k no? Choice of gpu will be most likely a AMD Sapphire 9070 xt Nitro+.

So yeah your honest advise either get a 265k or 285k (the 285k is about 270 euro more then a 265k) So i can either save money even tho i dont mind if it adds extra over a period of 5 years those extra cores might give me the edge. Will pair it with a G.Skill CUDIMM 9000mhz 2 x 24gb kit regardless and do a mild OC. I do know the 265k has lower latency over the 285k. If the 265k is more then plenty power incl long term with the above usage pls tell me so or better go with a 285k in this case money isn't really kind off problematic. Advise is appreciated.

Honestly? No. I don't think it is worth it, but if you spend a lot of time waiting around for stuff to complete and time is money, then that's your call.

To be more blunt, the 265K has 8 P-Cores and 12 E-Cores, whereas the 285K has 8 P-Cores and 16 E-Cores. It is around 10-15% faster (best case) in long-run tasks compared to the 265K.

In my opinion it's not worth it for 4 more E-Cores. You spend like 200-250€ more for it so it's smarter to save the money, get the 265k and maybe update sooner to a newer generation CPU with the money you saved going for a slightly lower tier CPU.
