Lenovo needs to get a 18" laptop.
The 4070 have a good result in Classroom Blender Optix render with 19 sec.

You mention the cpu being slower, but single core perf on the amd seems higher. Since most games don't use more than 16 threads, wouldn't the amd chip be faster for gaming?

The screen cannot get a score of 92 points in any way, and not more than 50%, because. does not meet Lenovo's declarations of a contrast ratio of at least 1200:1. With what we expect in 2023 - 2000:1 (LG "Black IPS" panels) and as minimum is 1500:1, for semi-matte screens.

That is, the author tested, in fact, a defective laptop in terms of screen quality.

The noise is increased, despite the fact that Zen4 consumes almost 2 times less with acceptable performance than the Intel version. The cooling system is poorly balanced.

The system memory is terribly slow, as always with AMD platform. This is a complete shame against the background vs. of 30-50% faster with Intel.

From my point of view, this is not a "gaming" laptop. If there is no 4090 card. And from the point of view of a working laptop - the processor is too weak for 2023. 7945HX is required. In addition, it has a plastic case and lacks USB40/TB4 ports and slow lan - only 1Gbps, which is a shame for 2023 at this price. We are expecting 5Gbps. Plus a completely shameful 720p webcam instead of the expected 1440p@60fps with autofocus.

Everything else will be decided by the market price. It will be lower - there will be sales.

Runs easily that badly optimized shi*fest of Cyberpunk at maxed details - not a gaming laptop for NikoB.

True, it was maybe good back in 1993 but not today 👍 The absolute minimum to do any work in 2023 is the Frontier/OLCF-5 with its 606208 cores, anything less is too weak.

+1  I think they have been caught by the trap and the intel lie.
That's right, AMD performs better and I think that Zen 4 Phoenix at 4nm vs. Intel's 10nm is much superior since it produces lower temperatures, less energy consumption and let's not forget that it has artificial intelligence which Intel does not.
Interesting comparison, you would have to see that performance in games.
Now it only looks like an ultrabook with the Zen 4 Phoenix APU but without a dedicated graphic, a comparison between RDNA 3 vs Intel Xe since many cannot afford so much money and prefer a 2.2lb ultrabook

Well a 5800H get 13000 in Cinebench R23 , this one gets 18000. Is that a good, okaish or mediocre evolution?

The Legion Pro 5 can be had with a 7945HX in some markets (EU and Asia, not US).
I have one since yesterday and i am very happy with it. I use it for software development and occasionally gaming.

I get about 30000 CB23 with <40db fans and 33000 with 44db fans (90-95C CPU temps though, but care more about noise).
I had better results using Legion toolkit and a custom profile because in Lenovos Vantage the fan curves cannot be adjusted low enough. The built-in profiles in quiet and balanced modes have way too high (and loud) fan curves.

Hello, Ngo and NBC crew. Great job on the review as usual. I noticed the photos of the PC internals are much improved now. Thanks for listening to our feedback, you guys rock.

New Laptops With ZEN 4 7040 Phoenix Acer Gets Ahead Of Big Manufacturers With Swift Edge 16: Updated With AMD Ryzen 7040 Series APU And Wi-Fi 7 Near $1,200.
The surprise is the good performance of RDNA 3 and Wi-Fi 7

I need some proficient HELP ...


I'll buy a Thinkpad 7945HX whenever it's available. I will NOT need a dGPU but I finally accepted that I will be obliged to buy it ... it's OK ...

I know it's not the best option BUT ... 50% of the time I will be encoding video through Handbrake ... probably V1 codec. SW encoding ... without the dGPU. I'll need a powerful CPU ... which I'll have it ... AND ... a pretty powerful refrigeration ...


The 7945HX integrated GPU is MORE than enough for me. I had thought to switch off dGPU (through BIOS) in order to get all the watts for the CPU (and less heat to dissipate) ... BUT ... I am afraid one of the FANS will become unoperative or directly off due to the new BIOS dGPU setup ... and I will NEED as much cooling as possible ..


How do you see it ???


Thanks a lot.

You don't need to do any of that. Modern power management in laptops means the dGPU is completely off when not in use. It does not pull any power or generate any heat.

A laptop with a dGPU might actually be better for your use-case, because they usually have twice the cooling power, and the entirety of it will be used to cool just the CPU in your case.

Excellent !!

Actually ... at one point in time ... I started to suspect about that. That's why I finally "ACCEPTED" to agree with the dGPU. :-)

You have exactly understood my use-case. Besides a great CPU ... I will need BOTH fans working pretty hard cooling it ... I guess one will cool it 'directly' ... and the other one will do it through a 'vapor chamber' ...


I hope running Linux won't be a disadvantage regarding to the 'power management' ...


Thank you very, very much !!!!!!!

Fully agree on too much fan noise on the built-in profiles. Take a look at the witcher screenshots in the review. The gpu sits at 67°C in performance mode, which is 20°C under nvidia's thermal limit. I would prefer 80°C and quieter fans.

Gunter, could you tell us something about fan acoustics? I intend to use a laptop stand and my current computer suffers from some high-pitched fan whining sound when standing on it. When using it on the desk it's nearly inaudible, but I want to use the stand for better airflow and ergonomics. I don't wear headphones so fan noise is critical too me.

@Gunter and @Allen: Have you noticed any fan (coil) whine under load (e.g. gaming) when lifting up the laptop?

A laptop without a 4090 with a 2.5k screen is by definition not a gaming laptop. I'm very sorry for people too poor to buy a solution that pulls new releases in ultra quality 2.5k at least at 60fps.

Let me remind fools, like the troll above, that mobile 4090 is 1.5 times slower than desktop and 3-4 times noisier in a laptop.

So drop any hopes of a "gaming" laptop with a 2.5k screen unless there's a 4090.

And for good - only idiots (with rare exceptions, when a person is on the road, on a business trip) buy to home "gaming" laptops, because the desktop is at least 1.5 times faster, cheaper and quieter at times. Only there you can play comfortably, without a headache from the wild noise of 45-50dBA.  At the same time, in a desktop with the same processor, you can change the top one 2-3 times. video card, which cannot be done in a laptop.
