The first ThinkPad with Ryzen 4000 has arrived: AMD much faster than Intel

[Waynish]

How will this model stack up to the T495? When will the T series w/ Ryzen & Vega be updated again?

why can't these E series laptops have a better display option, like the 500 nit HDR display? this would be a perfect laptop for me if it wasn't for that shitty display that seems to be the only option..

Because it's supposed to be a budget option for businesses - i.e. cheap and nasty option for employees you don't care about. ;-) I'm not sure about the E14, but E15 with Intel isn't any better IIRC. And don't forget the tiny battery. One thing I liked with Dell was the option to forgo a 2.5" bay and have a bigger battery instead.

It's TSMC who is producing.

And AMD is the one who is booking capacity. It's their job to book enough.

"The old Vega 10 iGPU is about 40 % slower"

as a amd fan, thats good to know. It was looking like Intel's igps were becoming a match for amd apuS, but Renoir  seems to retake that important crown.

If AMD, w/ a little help from similarly motivated game developers, can crack the magic playable games at 1080p on affordable general purpose mobile devices, amd will be farting through silk.

Nice laptop, no SMT means no purchase. I'll be looking forward to either a 4800U model or a T14/T15 with the Pro 4750U option. They're really forcing me to look into true business laptops as those use the Pro line which is all SMT enabled.

You're shooting yourself in the foot by going out of your way to look for laptops with SMT, because in hindsight, it turns out to be a huge security liability. For a deeper discussion, see "Is Hyper-Threading a Fundamental Security Risk?" on ET.

Granted, it may turn out that AMD CPUs aren't vulnerable enough to justify turning off SMT, but I would still think twice before going out of the way and paying more in order to get a system that has it.

Even if Tiger Lake laptops aren't yet on the market, at the pace Renoir laptops are released and especially available, I think we can safely say Renoir and Tiger will fight out this round. Lets see what Intel brings, hopefully they will step up their game.

It blows my mind that people do judge AMD based on the lowest tier model. Wait at least for Thinkpad L for uncompromised performance.

The battery runtime of the AMD model is a bit shorter compared to the Intel SKU. We see a deficit of ~14% in the video test (9h vs. 10.5h) and ~8% in the Wi-Fi test (7h vs. 7.5h). We performed both tests at a brightness of 150 nits.

Very strange results.
Acer Swift 3 SF314-42-R4XJ with 48Whr battery with the same 4700U have 16h 08min in video test.
I don't believe that 3Whr and 1,56" display size difference can give so much difference in power consumption.
What power mode was in Lenovo Vantage app?
You already had unrealistic low results with G14 before and retested it.

[Andreas Osthoff]

The Lenovo Vantage App does not have separate power modes anymore, it is now controlled by the Windows settings (also explained in the Vantage app).

Because I am yet to come across a CPU with SMT that does not allow disabling that feature, I would say that price sensibility is the deciding factor here. SMT exists for a reason, and it does have significant performance advantages that should not be disregarded. As long as the OP is informed and is fine with the price difference, it is hardly like shooting himself in the foot -- it's an useful *option* to have, that can be turned on or off according to the threat model at that time.

Ok! In that case, what mode was in Windows settings?
Do different performance modes make any difference in power efficiency?

I really don't get it, why it can be so big difference between Swift 3 and ThinkPad E15 in terms of battery life with the same CPU and almost identical battery. 1,56" display size difference can't affect so heavily.
Acer have ~55% longer battery life.
It should be something wrong with BIOS/firmware/drivers/Windows.

Not "may turn out". IT'S NOT. AMD's Multithreading is fine, Intel's CPUs are like a cheese, full of security holes in every feature they implement. Don't spread Intel propaganda.

So what are we looking at in terms of U.S release? From what I recall these were supposed to release in June but that was before CV19. No coming soon or any info on Lenovo's site although these there is a page on their Egypt site about the t14s and they seem to be available for pre-order on Bhpoto.

Where is the full review?

Backlight consumption should scale with surface area. If a display has 20 % larger diagonal, it has 44 % larger surface area (assuming the same aspect ratio) so you need 44 % more light to achieve the same luminance. 1.56" doesn't tell you anything.

Yes, there could very easily be something wrong with firmware or drivers. Or it could simply be a stray background process. And if you do it just once, you've got no clue how repeatable your numbers are.
