Snapdragon X Elite CPU performance nearly identical on battery and plugged-in in Vivobook S15 benchmarks

[Redaktion]

Tests and reviews of the Qualcomm Snapdragon X Elite have officially started rolling out. Although much of the reception has been lukewarm, a test by TechTablets revealed that the Snapdragon X Elite performs virtually identically when on battery and plugged into the charger. This is compared to x86 CPUs that often lose up to half their performance when on battery power.

This is compared to x86 CPUs that often lose up to half their performance when on battery power.

1% is also "up to half".

Just from your very own tests, and there is quite a lot of them to even bother to link all, but this is fairly incorrect if you really want to claim something closer to 50%. There, just one example (out of many here): Lenovo ThinkPad T14s G4 review: Business laptop is better with AMD Zen4:

"In battery mode, performance remains stable."

...

"GPU performance does not drop in battery mode."

But nah, Flopdragon has revolutionized the PC. Qualcomm propaganda goes on...

Btw, I simply love it how performance of the Flopdragon is barely similar to the Meteor Lake but only in native ARM apps, it gets to be much slower when using translation. Battery life is similar or worse (https://www.youtube.com/watch?v=Royg1kgDobY&t=1961s), it runs hotter and louder than Intels and its iGPU is weaker than Iris Xe but hey - it's not getting slower in battery mode, tremendous success.

My X1 Carbon (i7 1365U) is identically fast when plugged in and when on battery, btw. In all measured benchmarks.

Flopdragon. Lol. Thank you both for pointing out other journalistic and review inconsistencies when Flopdragon is being compared to AMD and Intel notebooks reviewed by Notebookcheck.

What I noticed was that Flopdragon managed only 9 minutes more compared to the Ryzen 7 8840HS in Notebookcheck's wi-fi test. That's against the HS variant which has a much shorter Wi-Fi battery life than the U variant as evidenced from the HP EliteBook 845 G10 reviews here. 9 more minutes. About 1% more. Talk about falling short of the hyped 22 hours of battery life.

Have much of an 'agenda'?

Clearly some of the writers/editors on this site and others are:

- Team Blue haters
- Team Red lovers
- Samsung haters
- Apple haters
- Anything new that may (or NOT!) actually be any good, parrot OEM propaganda

Of interest to many that are watching is exactly how inflated was Qualcom's hype before these products got into the hands of independent reviewers?

Are they: as good as they claimed? Almost as good? Better? No where near?

Inquiring minds want to know.

In battery mode, the CPU performance is reduced slightly (~8 %)

And I must say this performance in CBR15 is simply shameful for 2023 - only 1100-1200 points in the multi-threaded test. The 7840U with a lower PL1 (18W vs 25W for 1365U) has a performance above 1500 points:

And with PL1 equal to the same 25W as 1365U, 7840U is a monstrous 60-65% faster!:

И вот еще тесты 7840U на PL1=25Вт, как у вашего 1365U:

So the shame of Intel is obvious. Only Meteor Lake rose sharply, and again only because some of the chiplets in it are made by TSMC. And LunarLake will not be produced at Intel factories at all, its production will go to TSMC using the "3nm/6nm" technical process. That's why I wrote that AMD's best years are behind us... but this «war», not in favor of AMD, will break out only by mid-2025.

Thing is, this suggests that the ARM chips are intentionally throttling their performance in order to maintain thermals.

These are operating at 45W TDP which is comparable to Intel and AMD, but with those, they throttle down to improve battery life when you are on battery. On the other hand, when plugged in, the Intel and AMD chipsets can clock up for better performance at the expense of thermals.

Basically, the ARM devices are running in 'battery mode' all the time.
