99% of the time these laptops are used with less than "average load". This means that L5 is many times better in terms of noise (unless, of course, the numbers in the review are to be believed ;) ) "Extreme", which does not give anything to the buyer at all.

QuoteLenovo-Legion-5 [...] Only 29.3dB @ 103W...vs...46dB @ 138W... ;)

That test also wrote: "Running Witcher 3 on Balanced mode would result in a fan noise level between 43 and 48 dB(A)"

Compare to the maximum 45.5 dB under full load of ThinkPad X1 Extreme G5.

Therefore, the Legion is quieter at low load while the ThinkPad can be quiter under high load. Both have their merits.

Every +6dB is twice as loud. Thus, the cheap Legion 5 is 5 times quieter, while consuming 27% less in an average load.

So which model do we really have "Extreme" in a good way and a bad way?

Quote from: NikoB on December 07, 2022, 17:25:47Maybe it is "extremely" quiet, therefore, with an average load?

What dB values at what fan modes and speeds do you expect for a 17,9mm thin notebook?

700Gb/s+ - it, of course this is my typo.

Well, I want to note that in the "Extreme" version there is plenty of space on the side for RJ45 with 10Gbps without having to buy an external adapter on the TB4...

And the question is, when will top-end laptops finally start to solder at least 32GB of HBM memory with a bandwidth of at least 200GB / s (video cards have long been 700TB/s+, if that...)? This option already deserves the honest prefix "Extreme" and the price allows it, unless, of course, the Japanese R&D of Lenovo beats the buckets, riveting the same type of solutions like everyone else...

Apparently marketers decided to make fun of technically illiterate buyers of this "miracle of technology".

Well, firstly, Lenovo is again deliberately lying in psref about laptop support for 8k@60Hz resolution on the HDMI port, although any adequate person with basic knowledge in arithmetic can easily calculate, knowing the HDMI 2.1 bandwidth of 42Gb/s (excluding overhead traffic) that 7680x4320x24(bit)x60 in 4:4:4 lossless mode requires at least 48Gbps of pure data excluding service traffic. Not to mention 30bit (HDR), where you need even more... Support is only provided with lossy DSC compression, but this is not a monitor mode.

8k@60Hz at 4:4:4 lossless at 24 bit only supports full Display Port 2.0 (4 lanes x in UHBR20 mode). But this is not here, so the laptop does not support lossless 8k mode for monitors. Movie/TV only.

The Extreme prefix should mean that all the hardware works, at least, at the limit of its performance, according to the specification and even better! But what do we see in reality? Let's start...

The processor does not even reach the typical PL2 level of 115W according to the Intel datasheet for 12700H. But this is the "Extreme" version of the laptop, right? So the owner has the right to expect at least 130-150W per impulse (turbo) mode, not even the typical 115W from Intel is not impelemented, right? But it is a fail, as it does not even compare with some ordinary laptops...

Go ahead, the screen is only 60Hz, although 4k@120Hz screens have been around for a long time. Here, however, for some reason, a touchscreen in 16" is attached, apparently this limited the developers. But why?

Next, we move on to RAM. Well, it's okay that it's single-channel (unlike the author of the review, the owner, of course, will immediately buy a second 32GB memory plank, although Lenovo's greed is simply amazing at a price of 3500 euros and a penny cost of 64GB DDR5 4800 - it would be better if they immediately unsoldered LPDDR5 6000, which was promised in another laptop, namely "Lenovo Yoga Slim 7i Pro X" (see newest review), where even with the LPDDR5 5200 in reality (yes, yes, Lenovo simply cheated buyers here), where the memory obviously works almost 2 times faster in dual-channel mode, which is clear you can see by the speed of the memory in the "Extreme" version in single-channel mode - it is enough to multiply the speed in single-channel by 2 times in the mind... Those, a laptop for 1150 euros from Lenovo turned out to be more than 1.5 times faster in terms of speed of ram. It turns out that the "Pro" version is cooler than the "Extreme", Lenovo? Is it okay, marketers?

We go further, picking substances "Extreme" from Lenovo. We look at the exhaust temperature - it again exceeds 50C and the exhaust definitely goes straight to the screen. How long will the panel electronics(limited for max 50-55C) last under such loads and temperatures above 50C, Lenovo? Is this really the "Extreme" version?

Now let's move  to the videochip from NVidia. What we see in TDP is 95W, although in Legions 130-140. It is obvious that even up to a certain norm it falls short, not to mention the "Extreme" version.

Maybe it is "extremely" quiet, therefore, with an average load? Again, the owner is waiting for a complete fail.

Maybe it consumes extremely little and therefore with extremely long battery life? And here is a fail.

Lenovo - please remove "Extreme" from the name, do not disgrace yourself. There is nothing "Extreme" here, because of which someone will reach for their wallet to shell out as much as 3500 euros. Well, maybe 1500...then it's ok for buy.

Für 3500Euro?
Ernsthaft, dafür ist das Teil einfach nur unterirdisch.
Das taugt ja nicht mal zum protzen.

Danke für den Test! Eine Frage zur Akkulaufzeit: Wie habt ihr das geschafft, dass er so lange hält?
Ich habe den P1 Gen 5 (i12700, A1000 und 165 Hz NonTouch-Display) - und selbst auf minimaler Helligkeit im Stromsparmodus werden mir maximal 5 Stunden Laufzeit angezeigt. Man sieht die Prozentzahlen quasi 2-minütlich sinken. Liegt das vielleicht an der Vapor Chamber Kühlung, dass der X1 länger hält?

Und bleibt bei euch die Tastaturbeleuchtung auch an, wenn der Bildschirm bei Nichtbenutzung ausgeht? Das macht doch gar keinen Sinn und kostet nur Akku.

Top Rated Award für kaputtgesparte Tastatur, Single-Channel-RAM mit unterirdischen 33 - 37 GB/s Geschwindigkeit, spiegelndes Display und Auslieferung noch mit Windows 10 statt 11?!

Am Tastaturlayout stören mich v.A. die kleinen Pfeiltasten und kurze  linke Shift-Taste. Beides hätte leicht vermieden werden können: Pfeiltasten nach unten mehr Raum geben. >-Taste entweder neben die Leertaste packen oder >, <, | durch die Umschalt- oder Funktionstaste auf YXC doppelbelegen.

Die Kühlung ist angesichts von 17,9mm Gehäusedicke, 80W PL1 / 112W PL2 der CPU und 95W = 80W + 15W der GPU trotz bescheidener Luftschlitze gut gelungen mittels Vapor-Chamber und 45,5dB unter Volllast. Das zeigt, wie leicht es für alle Hersteller sein sollte, 39 - 43dB unter Volllast zu erreichen bei ca. 28mm Gehäusedicke, entsprechend bis zu 1cm dickeren Lüftern (oder bei mechanischer Tastatur 0,5cm dicker), größeren Luftschlitzen, sorgfältig installiertem Vapor-Chamber, AMD-CPU mit maximal 45W und GPU mit 80W. Ich werde keine Entschuldigung irgendeines Herstellers mehr akzeptieren! Erträglicher Lärm bei gut mittlerer Geschwindigkeit auch der GPU ist immer möglich, z.B. mittels eines ausgeglichenen Lüfterprofils für dann solche TDP-Werte. Zumindest die Kühlung hat angesichts der dünnen Bauweise den Top Rated Award verdient.

Die Compute-Benchmarks der GPU sind interessant. Im Vergleich zur verwendeten 3060 erreicht die Vergleichs-3070-TI meistens 14 - 39% mehr, aber V-Ray-5 CUDA zeigt dann mit 74% mehr doch sehr deutlich die Grenzen der dünnen Bauweise und begrenzten TDP der GPU trotz dafür guter Kühlung auf. Ganz besonderen Dank an den Tester fürs Aufdecken dieses Sachverhalts! Wer Compute-Aufgaben hat, sollte sich nicht auf 3060 Laptop beschränken.
