slowdown in performance increase? haven't we been there for a decade?
- smilespray 8y agoFor PCs, sure. Not for mobile chips.
- wmf 8y agoApple is claiming only 15% performance improvement for the A12 CPU cores; in the past it was more like 30-50% per generation. But 15% is far more than the ~5%/year that we've seen in PC processors.
- pertymcpert 8y agoYep, but also they're claiming 40% lower power consumption. So it's safe to assume they could have traded that power efficiency gain for more performance. Despite that, most of that gain in PPA is due to the 7nm transition, rather than micro-architectural developments.
- Bud 8y agoThat's assuming they could cool off such a design. Cooling is harder to deal with in a mobile device. Can't just throw big fans in there.
- djrogers 8y agoCooling is a factor of energy input. If they can cool the A11 using 40% more power, they can cool an A12 using the same power. That said, I’m more than happy to save that extra power - battery life is a good thing.
- ewzimm 8y ago9x performance on the Neural Engine compared to the A11 is the big increase. We'll probably see slower CPU/GPU increases with massive advances in AI for a few generations now.
- dis-sys 8y ago> But 15% is far more than the ~5%/year that we've seen in PC processors. thanks to threadripper, there were huge jumps for PC in the last 12-18 months. 2990wx bumped Cinebench R15 score from less than 4,000 (Intel's 7890XE) to 5500+ overnight.
- smilespray 8y agoIt has to be said that the core Threadripper concept is just throwing more cores at the problem.
