No, not if you're doing heavily-multithreaded work.
So, that works out to
31.3% faster SPEC2017int and
37.4% faster SPEC2017fp. In Raptor Lake, the differences are surely even
further amplified, but they didn't repeat the same test.
People use these CPUs for more than gaming, you know? But, for the casual gamers, DDR5 is quite likely a boon for iGPU performance. You'd need a big iGPU which makes it harder to test, since those only shipped in the BGA laptop-oriented processors. Did any Alder lake 96 EU mobile parts ship in laptops with (LP)DDR4?
Don't worry, I won't.
Sounds like wishful thinking, IMO. Sure, prices have had some effect on suppressing purchasing, but I wouldn't say that's the biggest.
I think the biggest factors are that most upgrades happened back in 2020-2021 and the economic downturn/uncertainty. The latter had two effects: to put off anyone still in the market for an upgrade and to turn off the taps on corporate spending.
