I used to run a 3y old Lenovo P1 as my work computer. It was so power hungry that it could not charge through USB C. And as soon as you plugged the power brick, fans started. And it wouldn't last more than 2 or 3 hours without being plugged in. Can't say how other brands do, but if Lenovo are the best...
Well P1 is a mobile workstation, right? Probably some dedicated GPU in their messing with it all.

That's the experience to expect with that line of Thinkpad, fwiw.

But yeah, x86 laptops are so all over the place its crazy.

(I also ride or die Thinkpads after using some for 10+ years and only now are they being benched, but that is not to say they are all gems or you can't configure one to cost too much, etc.)

Plus, the older USB-C chargers were limited to 100 watts, while the newer ones since 2021 (USB PD3.1 compliant ones, anyway) can charge up to 280 watts.

Lenovo's are the only ones available for a reasonable price with RAM fully specced out (at least the last time I looked on eBay).

Dell/HP pretend like they sprinkle gold dust on their workstation laptops.

Yeah, it comes with a, useless for me, discrete GPU. I tried to disable it but didn't succeed 😞 It looks like it couldn't be configured without a GPU back then. All I wanted was a >4 core CPU for development.

Anyway it was a displeasing surprise after the T480s I used to run or the two previous Lenovo I had even before, both I really liked. I don't want to derail the thread any longer, so I'll stop ranting, and I got another laptop that really fulfills my needs with none of the shortcomings of that P1 😀

My P1 is from late 2021. Though it might have been stocked for a few months.

More updates on that microcode update for y’alls:

Multithreaded workloads see the biggest decline, but it’s not too bad.

From the conclusion (after translation):
According to this, Intel has adjusted the voltages and avoids higher voltage peaks. This will also have a small impact on the clock rates. In the vast majority of applications, however, this is not noticeable and the performance is almost identical with Microcode 0x125 and 0x129. Any existing differences fall within the range of measurement inaccuracy. It feels like the Core i9-14900KS is throttled a little more strongly. But our sample is not a particularly good one anyway.

The single-threaded performance even seems to benefit slightly from the lower voltages, which is also evident in some games. However, this only applies to games that benefit from particularly good single-threaded performance and can be justified by the fact that the lower voltages ensure a lower thermal load, which in turn makes higher or more stable boost clock rates possible.

To what extent this now reduces the degradation of the processors is still another matter. This should also depend on how good or how bad the processor was previously set and how often and for how long it had to cope with too high voltages.

Our (and also those of other publications) seem to confirm Intel's statement that there is no to hardly any influence on the performance of the microcode update 0x129. To lose 5 or even 10% of performance here - this concern seems to be completely unfounded.

The loss from multicore will make a big difference to many benchmarks and application. Gaming will be the least affected. The x3d series from AMD already owns that.

Looks like the biggest decline was just under 5% in V-ray for the KS; which for some reason gets hit more than the K. Surely it’s not great but it’s not terrible either. The K models come off best and it’s minimal, so I’d say it’s a wash.

I have not seen any widely recognized benchmarks that prove that, so I would disagree. I would also not touch any 13 or 14th Intel CPU with a 10 foot pole from everything I have seen.

Cinebench. Blender. Corona. Geekbench. 7zip. Handbrake. V-ray. Y-cruncher. Those are all mentioned quite frequently from what I’ve seen from tech/cpu review sites. Would be interesting to see Spec2017 for n-thread but, the gist of the changes is out there now in multiple places.

But for sure the instability issues don’t invoke confidence, that’s fair.
That’s why Arrow Lake can’t come soon enough and not just be a tiny improvement. Gotta be decent.

I read that article but did not share it because it does not bring anything new to the discussion. Jay and hot hardware already confirmed the performance hit is minimal. Currently the topic is on whether it's anything more than a band aid solution. The minions on reddit are pushing the disinformation that everything is all better now, and it was always an overblown issue. No one is buying it, or raptor lake CPUs.

My hot take is that it's another dirtbag tactic with the primary goal of not ruining bigger bar better for the Zen 5 launch. The ancillary goal is to push the above narrative that the issue is fixed. As they know damned well it'll take many months and many samples to determine if the amount of degradation is a more normal level or not.

The new MC obviously cannot reverse the already damaged CPUs. Some boards still only have a beta bios, and the implementations are erratic. Skt 1700 is cursed, as the kids say. That they never stopped selling the CPUs is the most scummy move of all.

Maybe I'm just too old school, but back in the day when I was getting game crashed due to overclocking or some other BIOS setting, I would run stability test software and tweak settings to get to a point of high confidence in system stability.

What I see now is people running out of the box motherboard overclock settings (MCE XMP and the like) and being completely oblivious to stability problems that exited right away.

Yes, I'm aware of the degradation problems and how that plays a big role in all this. I'm just saying that people had these CPUs pushed beyond their limits from the get go and degradation worsened the problems they already had over time.

Now we have games with code (shader compilation) that sort of acts like a stability test putting the issues front and center right in their faces.

There are also those that were on the very edge of stability with the "hot" out of the box motherboard settings. The slightest amount of degradation would make the system unstable.

What I'm seeing people do is try workarounds for the crashing rather than apply BIOS fixes/settings. It's ignorance building upon ignorance.

It's clear that the CPUs were pushed too far by both Intel and the motherboard venders who wanted to see "numbers go up" in reviews

Watching that is some morbid entertainment. From early on the chat is full of people noting the known Intel crashes and degradation, does Asmongold ever acknowledge those? Not sure whether he's really oblivious to all this or just inanely stubborn (he probably earns what's worth new chips through such entertaining streams alone anyway).

While I don't disagree with the gist of your statement, as someone who has built many (relatively for just a guy) PCs its been near impossible to know what it going on for some time now.

I think the first time Igor responded to one of my posts I was talking about building with Intel on a 10th gen but enabling XMP did who knows what in addition to setting the timings and speed of the ram to the hot profile (IMO, this should be all it does. ram voltage, speed and timings based on the stick data) so I would manually set the P1 and P2 wattages and durations because most of the time, out of the box, the Intel boards had P2 set to the moon and for an unlimited or extremely long duration. And then I'd memtest 24 hrs then Prime for 24 hours then loop Unigine Heaven overnight then stamp it good if it cleared all the hurdles. That's really similar to the burn in Falcon NW did to my first PC back in ~2002 and that seemed like a reasonable test to me.

And Igor was like, why set those power limits? And to what?

For the settings, great question, I had to reference ARK every time I was building an Intel PC because the bios settings never seemed to be what Intel specs were to get this data. Ridiculous.

And for the why? For me it was the best and quickest way I knew to keep these boards from doing some runaway craziness (in all fairness, the voltages could still go ape and I guess this wouldn't help much) on these CPUs since the firmware had moved so far away from "stock settings" by default. Also, I like quiet builds with nice fans and keeping the boost power reasonable is all part of controlling peak fan speeds & noise.

And here we are. I am not surprised in the slightest that many people building their own PCs enabled XMP, set the boot device, saved and exited the firmware interface never to visit it again. That should be safe. That should be reliable. In no way should we blame the casual PC builder for not being able to trust the configuration out of the box. This should have been part of Intel's firmware guidelines since we moved to UEFI (if not earlier) and I'll die on that hill.

Please don't kill me. :D

If it isn't stable out of box, it's broken. You should be able to throw and go. XMP and EXPO are technically overclocking so changing those is really YMMV with no guarantees.

I guess I'll keep repeating this since the "No one stability tests anymore" pesists. Users including one of the hosts of the full nerd podcast had their degraded CPU pass all the normal stress tests. Ergo, the usual stability testing was unilluminating. Oodle and other compression-decomprssion tasks that are sufficiently rigorous revealed the damage. Jumping Jeebus on a pogo stick, they were telling people to install Nvidia drivers 10 times in a row to test for degradation. 🤣

He blames the game at one point. I think he is trying to avoid acknowledging the CPU is damaged because it is going to hit him in the pocketbook. GN reviewed a PC from his S.I. biz -

Love it.

With regards to XMP/EXPO how are mortals supposed to set their memory to the speed advertised on the memory stick box if not for using those settings. There are so many settings - and sub settings - that are embedded in the stick info that thinking people can do it by hand is silly.

XMP/EXPO shouldn't be overclocking at all, that's should be just setting your ram to its advertised clocks/latencies.

I mean, I get it. Doomguy doesn't need XMP/EXPO, he'll just rip and tear until its finished. But I do! I remember the past and so many blue screens and hard BIOS resets as I set the timings manually on fancy DDR. I am over it. Just work, darn it.

Looking back for the quotes was nice trip down memory lane. Maybe I remembered wrong, but back in 2020/2021 we were talking about disabling MCE, etc. Trying to get the boards to play nice with settings we actually set instead of having "optimizations" enabled on one screen that totally overrode what you might put in on another screen. This train wreck has been coming for quite awhile.

Maybe we should be lauding Intel's chips for being so darn tough they were hard to kill in the past.
