AMD Launches Ryzen 5000 Mobile: Zen 3 and Cezanne for Notebooks

CPUs have been progressing faster in the last few years, mainly because of AMD's Ryzen line. In laptops, 4 cores are now standard, and if you can gen one of the AMD 4000U CPUs, 8 cores with good single-threaded performance are relatively cheap. Same thing on desktop, you can get 20%+ more performance by upgrading the CPU.

Sure, it's not the same as 486 vs Pentium, but the Ivy Bridge-era CPUs that were used for such a long time are now equivalent to low-end CPUs, it's no longer universally better to get an old i7 vs a new i5. That said, if you're happy, there's no reason to upgrade.

I'm in the process of returning an i3-9100 based Dell Precision. It's a true 4 core and despite no hyper-threading on the benchmark sites it beats my Haswell Xeon E3 in both multi and single threaded tests. In reality however it's a dog. It gets bogged down for the lightest workloads.

It's also using MORE electricity from the wall, as the old PowerEdge T20 system was an ATX12VO design with a Xeon 1275L.

I'll extend your comment to say that old i7 is universally better than new i3 (and I should have known better).

SSD performance is quite important for perceived speed.

Core count > 2 doesn't help general responsiveness much with the current state of software.

I definitely disagree. When having a video conferencing app open can use 100% of a single core, 2 cores just isn't enough for anyone even remotely multitasking. Same with a browser running some demanding JS for whatever reason or system updates.
