Title: 7 nm AMD Ryzen 7 4800U is as fast as the 14 nm Core i9-9880H and at half the TDP, but there's a huge catch
Post by: Redaktion on August 28, 2020, 08:30:14
Can an 8-core 25 W cTDP Ryzen 7 4800U outperform the popular 8-core 45 W Core i9-9880H? They're much closer than what you might think at least until you start stressing the Ryzen processor over very long periods.

The huge catch is that you can't buy a laptop with 4800U anywhere.

If Lenovo didn't throttle every single one of their premium laptops down to the point of irrelevancy maybe it would perform better. 60C is nothing.

Uhhh, this isn't a 4800u issue.  This is a laptop issue. Lenovo sets the throttle profile.  And also, show me a 9880H in an ultra book that doesn't throttle. Lol

I normally like the articles on here, but this is clickbait.  You can't overlook 2 major aspects of a comparison and drive a conclusion.

Ah, classic notebookcheck. Comparing the 4800U in a thin and light notebook to the 9880H in a bulky gaming laptop and complaining about the former.

Ufff, how low can your journalists go?

 I'm not even sayin "put both CPUs in the same chassis and use the same cooling and check the difference", but it's dumb to use this example to draw a conclusion, I mean you're comparing a shitty device with apparently terrible cooling solution with some higher end devices with absolutely better cooling, "even" the MacBook Pro 16 has a significantly better cooling than the Lenovo. And based on this, you chose a controversial headline, so talk about it, OK, you won, but at what cost???
*insert "but at what cost meme here*

This is not a fault of the CPU. Especially if it's sticking to reasonable power draw even in the first run. It's entirely laptop's fault and limitation. The real problem is the availability of this processor. AMD might have a great product, but they're not very successful at getting it out there (and I would say that's true for the entire Renoir lineup, not just this unicorn of a CPU).

How much Intel paid to you of this B.S.?

Not a word about 45w 4800H vs 45w 9880H ?  You are comparing a sedan to a pickup truck.

It's not CPUs fault if its put inside a 14 inch thin laptop with smaller coolers.

Guys, get a real job.

this type of articles make me stop reading your page.

what a bunch of misinformation.

lol!

Yeah, this reporting is sad.
Thermal throttling from a limited cooling solution you say?

Who would have guessed.

This level of Captain Obvious testing...do you readers a favor and actually test apples to apples cases and maintain your reputation as a fair reporter.

Articles like this make readers wonder what else is passed on that is not so obvious. Are other tests rigged also?

You are playing with the reputation of you site. Is it worth it in the long run?

yeah 1 is a 14" 1.4kg ultrabook, 1 is a 17" 2.7kg gaming machine, but after years of experience in laptops reviews NBC conclude that these differences is not worth metion bcz  intel money is damn yummy.

Not even the slightest mention of the cooling system?

What do you call this, dear editor, because I call it unprofessionalism (and it's the most polite word I can find right now).

Reporting it in my google feed for being misleading and sensational - fits the bill 100%.

Amazing how many people here complaining about the comparison who obviously never bothered to read the entire article. Reading comprehension FTW!

Here's the end of the article for you -
"Since the Ryzen 7 4800U is so new, we'll have to wait and see what other OEMs can do with the processor outside of Lenovo. Its configurable TDP should allow for a wide range of compatible chassis designs and thus a wide range of performance differences between models."

Notwithstanding. A footnote on an obvious clickbait article does not make it any more reputable. Poor journalism none the less.

I have read the entire article, including the part you cite. The problem is that he is drawing conclusions about the processor from a single unit. And you can't fix that with a short comment towards the end. It's like saying at the end of an article that we can ignore all that we just read as it's a pile of nonsense. Why write nonsense in the first place? It's well known that chassis has big impact. And he doesn't present any evidence that it's processor's fault (like excessive power draw). He should have been talking about the laptop, not the processor. At best, this is an opinion piece. But it's not presented that way.

Classic Intel-shill written article.
How, you ask?
Compared a thin form factor laptop to a bulky MSI laptop in sustained performance.
It's a miracle that the AMD kept up with the Intel CPU until then with such little thermal headroom.

You are deliberately painting AMD CPUs in bad light, by making an Apples to Oranges comparison.
People, look elsewhere for honest reviews.

At the end, the review should say that Ryzen beats Intel under similar conditions because it certainly will, and with half the TDP. You don't have to wait for OEMs to say that since performance drop is clearly a cooling issue and has nothing to do with the CPU itself. Such a shame this isn't clearly mentioned..

fwiw, I have an i9 9880H in a NUC and it throttles constantly, it performs about on par with an 8th gen i5, no one is writing about that though!

worst purchase I've ever made

Signed up just to say.... Wtf

You can't compare AMD in small laptop and blame them for manufacturer throttling. Clickbait. I was looking for the "gotcha" but it's just in the sinister nature of the article. Smh

Intel CPU's do have a history of throttling badly in laptops and generally speaking in thermally constricted environments.
Though that CPU you have is hardly what I would call 'suitable' for a NUC.
45W TDP is only applicable for base clocks... when the thing pushes the clocks under load on all cores, power consumption will go up significantly.

Have you tried repasting the CPU with a higher quality thermal compound such as Kryonaut and undervolting the CPU perhaps?
It may not be ideal, but many people using laptops with Intel CPU's managed to get their temperatures well under control with these methods... perhaps you can try it too and see if it helps.

Can you show me 9980H after 5-6 looping benchmark without delay ? No throttling ??? :D
