But single core performance has been stagnant for ages!
Considering ‘Geekbench 6’ scores, at least.
So if it’s not a task massively benefiting from parallelization, buying used is still the best value for money.
- PartiallyTyped 1y agoI don’t think that’s true. AMD’s ****X3D chips are evidence that’s not true, with lots of benchmarks supporting this.
- bob1029 1y agoSingle core performance has not been stagnant. We're about double where we were in 2015 for a range of workloads. Branch prediction, OoO execution, SIMD, etc. make a huge difference. The clock speed of a core is important and we are hitting physical limits there, but we're also getting more done with each clock cycle than ever before.
- zozbot234 1y agoDoubling single-core performance in 10 years amounts to a less than 10% improvement year-over-year. That will feel like "stagnant" if you're on non-vintage hardware. Of course there are improvements elsewhere that partially offset this, but there's no need to upgrade all that often.
- gred 1y ago> less than 10% improvement year-over-year. That will feel like "stagnant"... Especially when, in that same time frame, your code editor / mail client / instant messaging / conference call / container management / source code control / password manager software all migrate to Electron...
- DrNosferatu 1y agoIt’s actually just 7% improvements year over year!

- ksec 1y agoThis. I just did a comparison between my MacBook Pro Early 2015 to MacBook Air M4 Early 2025. *Intel Core i5-5287U*: - *Single-Core Maximum Wattage*: ~7-12W - *Process Node*: 14nm - *GB6 Single Core *: ~950 - *Apple M4*: - *Single-Core Maximum Wattage*: ~4-6W - *Process Node*: 3nm - *GB6 Single Core *: ~3600 Intel 14nm = TSMC 10nm > 7nm > 5nm > 3nm In 10 years, we got ~3.5x Single Core performance at ~50% Wattage. i.e 7x Performance per Watt with 3 Node Generation improvements. In terms of Multi Core we got 20x Performance per Watt. I guess that is not too bad depending on how you look at it. Had we compared it to x86 Intel or AMD it would have been worst. I hope M5 have something new.
- DrNosferatu 1y agoThat’s 13% per year.
- DrNosferatu 1y agoI certainly will not die on this hill: my comment was motivated by recently comparing single core scores on Geekbench6 from 10 years apart CPUs. Care to provide some data?
