Alder Lake-S leaks

So many reviews like are using terms like “destroys” and “dethroned” yet none of them are giving much weight to the board pricing.

Jay has done some of his own power testing

what he found is by default his mobo is actually breaking PL2 anyway and pulling up to 270w at load.

another reviews did a big roundup of various boards, Gigabyte is the worst for this - using a 12900k on a gigabyte board will make the 12900k pull an extra 30w compared to Asus or Msi. yes gigabyte boards do top the performance charts because of this.

Jay is a plum
he is taking power readings at the wall and hasnt accounted for vrm losses or psu losses or even fans spinning faster due to the load or even the pch not being in an idle state anymore

270w - 8% for psu efficiency - 8% at a guess for vrm efficiency = -43.2W take a few watts off for fans spinning faster and other stuff
and your looking at 220-230W

about 50% of jay's video's he is talking out of his rear with no idea what he is talking about

Nevertheless some boards pulls more than others

 
Well got it all setup albeit temps are bit high well higher than my 9700k for sure but then I am using a puny Noctua NH-D9L with 2x 92mm fans on it temp until Corsair send me my standoffs.

With 7zip benchmark it reaches 72c not bad but not great but I haven't got a clue how to set this Asus bios up for the 12900k and the Strix Z690A Gaming so many different options I have no Idea whether it is in PL1 state or PL2 state.

I I enabled the CPU OV jumper on this board but I don't know if it's changed from stock I left it on Auto in the bios and it goes over 1.35v is this normal for stock?

1 thing I tried to try and lower temps further by Putting the SVID on best case scenario and the system crashes almost instantly when gaming, This worked on my previous 9700k and Maximus XI Hero.

I need some sort of bios guide for this mobo god knows what all these Asus Auto settings are doing.

Are setups are moreless the same be interested when you get your o/c stable and what settings you used .

Yeah I need to do a bit of research I'm not sure what stock voltages are for the 12900k but it's going over 1.35v and it has some weird LLC in the bios like 3 options or something, I'm sure more info will arise once more and more get setup.

It’s still all energy which needs dissipated in some form, and paid for money wise. There utility company is not going to reduce your bill to account for vrm loss. So it’s valid to talk about the draw at the wall .

Yup idle and maximum power draw under load measured at the wall socket works for me.
There is no fudging those readings.
 
I have decided to go with the 12700K. Is the Asus Prime Z690-A a good board for it?

Also I will be pairing with the Crucial 4800mhz DDR5 Ram and playing at 4K. Is this good enough?

Plus all that heat has to be controlled and go somewhere. a lot of the reviews are using the best coolers they can get. I'd like a review of all the current available coolers at the minute. It looks like only the tripple coolers are viable and many cases just don't allow for them.

Igors lab has done more benchmarks with the 12900k locked to 125w and it's impressive.

It's performance per watt is very impressive against ryzen 5000.

In most cases the 12900k gains very little extra performance from being allowed to go up to 240w.

if you want efficiency, lock your 12900k in the bios to 125w PL1 and on average it going to 95% as fast as at 240w PL2

Interesting. Most reviews paint a picture that Alder lake is fast but also power hungry and hot which makes it a no go in my book. This certainly change my perspective a lot. Alder Lake is certainly more interesting now. Wonder why the chip is allowed to go full hog like that. Its not a good luck IMHO. The 125w numbers would have drawn a much prettier picture, at least to me.

While some of the complaining about power numbers sounds like some people just want to minimize Intel's performance, I have encountered a situation that has me considering power draw more than I used to in the past.

I recently upgraded to a 3080ti that pulls up to 450w and this seems to be the straw that broke the camel's back with respect to my sim rig and the 900w UPS that I use to keep my racing uniterupted....

Between my PC, wheel, and transducer setup, I tripped the warrning beep on the UPS.

I have never seen my 5800X pull more than 155w so a more power hungry CPU will just make the problem worse. While I can fix the issue for now by getting a second UPS for the non PC parts, I can now imagine a scenario where a 4090 and 13900K would be too much for a single consumer-grade UPS.

I assume people who go all-out on PC performance also want to use an uninterruptible power supply, but how many are willing to shell out the money for a commercial-grade UPS to protect it?

I'm happy that we are getting more performance and competition, but there is a point where power draw matters, even on desktop, and I think we are only a generation away if things continue on as they have recently.

I see reviews stating Alderlake CPU 100+ watts more than competition but it's more than that
If you draw 100w more then you have to cool 100w more i.e bigger or faster fans - add 10 / 15 watts. Heat from mobo components (VRM's etc) more wasted power. The sum of that extra power is supplied by the PSU. 120W extra drawn from PSU ~ 130 / 140 watts. So again, the 100w extra is now 140 extra. The inefficiency just grows.

That's the board I was looking at and had originally ordered. Looks like a really nice board but the extra features and aesthetic of the Gigabyte GamingX won it for me considering the exact same price!

Get whatever DDR5 you can get hold of right now, this is all gen 1 DDR5 anyway then in a year's time when DDR5 isn't all high latency stuff, upgrade.
