Discussion the Death of the Desktop CPU

My friend had the Osbone 1 I played with it. CP/M was wierd.

The typo makes this funny.

@fastandfurious6 This you?

AMD Ryzen AI Max+ 395 vs. Ryzen 9 9950X vs. Ryzen 9 9950X3D Linux Performance Review - Phoronix

www.phoronix.com

You know, if you enable eco mode on the 9950X3D it can be similarly efficient to strix halo's CPU even with the high desktop idle power cost.

I've got a strix halo mini PC and a 9950X3D desktop that idles at 100W and in testing unreal engine compiles and other UE multithreaded workloads, 9950X3D system in eco mode uses the same power at the wall and performs the same.

Michèl Larabèl the myth the legend!!!


what is the eco mode on windows?

power mode set to "best power efficiency" ?
"energy saver" enabled ?
"quiet" laptop profile?
nvidia gpu "power management mode" set to Normal?
pcie express Link State Power Management set to Maximum Power Savings?
laptop "thermal drivers" installed?
manually disabling turbo?

too many knobs gets too messy

I see you're being intentionally obtuse. One single setting.

That's too messy, but you're totally fine with a laptop where you have to do all kinds of power management configuration all the time to get the best performance, or make it quieter, or maximize the battery life depending on how and where you're using it at any given moment.

To bring this up again,

Desktop CPUs will not die as long as AMD and even INTEL offer 3-4 generations of CPUs on the same platform.

Some just want to upgrade ONLY their CPUs and the no other form factor offers that but the desktop

 

[fastandfurious6]

well ofc they won't go off-market overnight, there's gazillions of desktop pcs on this planet lol

but in practical terms desktop cpus are already over.........

you literally have the #1 flagship cpu in the world, 9950X, in a handheld (Halo form)....

....never before possible!

also 9950X = 9955HX, desktop version only achieves around +15% on the very high wattages

and the difference will keep decreasing, zen 6 will be even more miniscule


basically 80-90% of performance gets reaped in mobile-friendly wattages, and very-high desktop wattages dont offer much more perf

the same theme will keep recurring in future chips

You can also power limit desktop CPUs and build them in very small enclosures.

I don’t want the desktop CPUs to die, it enables modularity that is a product of a bygone era and as long the Intel and AMD offer such CPUs many will buy them.

There's enough Corpos who like the form factor. That's it. Bascially there's cases where Corpos prefer not having the portability... afraid of the ol Five Finger Discount I guess.

Course a lot of that is AIOs.

why not enable laptop cpu/gpu upgrades?

 

[igor_kavinski]

why not enable laptop cpu/gpu upgrades?

Only possible with laptops that come with hefty cooling solutions. But let's be realistic here. The only reason laptop makers like making laptops is precisely BECAUSE they are NOT upgradable and they can look forward to making more sales in the next upgrade cycle which could be three to five years at most or as less as a year for people with deeper pockets.

One of my worst ever purchases was an ASUS Haswell laptop with Geforce 750. I made the mistake of buying it at launch. Six months later, ASUS upgraded the same model with Geforce 850. You can imagine how mad I got because that was twice the performance of the 750!

so >2kg class that's ok. anything below that is mostly used by ppl who dont know/care about upgrades

but also zen6 onwards upgrades will be less useful.... i.e. by the time zen8 comes out the laptop will need new everything anyway, laptops will be pocket devices that rollout to 20 inch monitor lol

dishing out 2k every 4 years for new high end complete mobile computer is reasonable
