AMD strikes back: Ryzen 9 7945HX beats Intel Core i9-13980HX despite much lower power consumption

[NikoB]

I have been advocating for a long time that the rules of the game be introduced for laptop manufacturers - the maximum consumption of a laptop is not more than 100W, in any series. How did the legal ban on incandescent light bulbs come out.

It is not clear why the authorities of all Western countries pretend that the wild consumption of computers is normal? Instead of real progress in performance per 1W of power?

Unfortunately, most officials and politicians are idiots and populists for the needs of the same stupid majority of the population ...

Since when does a CPU drawing over 120 watts is considered a "mobile processor"? Not while ago that was desktop enthusiast class... I'm wondering where this power inflation will lead us.

Blame Intel. Intel put desktop CPUs into laptops, starting with the "Alder Lake-HX" i9-12900HX and i9-12950HX.

AMD has simply taken the same concept and made it better.

I'd say more just blame x86 in general. Intel kind of became irrelevant years ago after Zen 2, so they shouldn't even be compared to or benchmarked against for efficiency.

Even though progress has been made with x86, the 10 hour battery life we are getting in todays devices were in arm devices 10 years ago. And it's still not enough. Even the most TDP limited throttled mobile x86 cpu still produces more heat and takes more power than the worst arm cpu on a samsung node.

It's no secret that when Apple switched to arm M1 SoC's there was a massive leap in efficiency and they were already considered industry leading in terms of battery life / heat / noise levels in laptops.

We should really just switch to arm for gaming already, I don't know why it hasn't been done. Games are already optimized for the switch so should be too difficult to port. Would help for the sustainability of the planet in general, using less energy and having to use fans less would reduce overall failures in general.

Holy words, but AMD is doing a good job in making the x86 platform as sustainable as possible. In both cases (AMD and apple) TSMC has many credits.

70-80W should be the maximum upper limit for laptop cpus, wattage. cant call any thing laptop if that pull over 100w.
If amd can deliver same performance then it should be appreciated in laptop stand point.
for me 45watt is an 8 core 14nmn chips wattage, 35w should be for 8 core 4nm chips and 70w is for 16 cores.

Desktop replacement exists for a while now and few complained of its desktop-like power usage. Gaming laptops has had 100W+ components for so long (CPU is just another addition since the Alder Lake-HX), and they're equipped with monstrous PSU (sometimes dual PSU is necessary). Also, wattage has nothing to do with fabrication process. A chip can be fabbed at 14nm AND consume 35W power, it's just not offer the same performance given by an identical chip fabbed at 4nm and consume 35W power. Kudos for AMD though for giving the Zen 4 superb efficiency when tuned to lower power levels.

AMD ZEN 4 Phoenix

One finds in every corner that the CPU has security gaps for malware, its AI makes smart phone calls and thus competes with China.

NikoB since you use those terms i am at liberty to use them, besides your totalitarian impulses you should go to politics to show your own idi*cy.

Tell me a 70w Apple laptop rendering a scene for 4 hours consumes more or less energy than a 600w system that renders the same scene in 10 minutes?

In politics, only bastards survive. And I'm not like that. I can easily smear a thin layer on the wall of any top politician in a public discussion. But my judgments will obviously not please the crowd of sheep, with whom the populist politicians work, which is why they are so successful, and not at all because they are really smart, in a creative way for the positive progress of civilization. As in reality, most officials are not smart - they go there, because they lost the competition in the private sector since school. But they are quirky, cynical and diligent enough to build a career in such a dirty environment.

A 600W system is not possible in a laptop - it will just burn out. The laptop needs to be quiet during normal operation and properly balanced to keep components from overheating for at least 10 years of trouble-free operation.

Now everything is different - there is a deliberate deception of ordinary buyers due to the wild growth of TDP and a sharp drop in long-term reliability.

While only Apple offers more balanced solutions, the x86 camp is essentially dead in this regard. Or slow or very noisy/hot and unreliable
