Sorry if this is off-topic but how would this chip compare to an ARM design that could handle 16 threads? Would thermal dissipation, power consumption, and performance be roughly the same or would they be significantly different? I want to be excited about this chip but thought that this was supposed to be the year we all get ARM-powered laptops/Chromebooks.
- toast0 7y agoThere's several popular ARM cores around these days. You would need to pick a specific processor family, at least. That said, I have seen plenty of ARM powered Chromebooks and I don't think any of them had more than four cpus or were known for high performance. It's not impossible to make a high performance ARM chromebook, but it's not the market people are building for. High performance x86 Chromebooks happen because once you've built for a dual core mainstream x86 laptop processor, you can also easily solder in a higher performance processor with the same footprint.
- blihp 7y agoYou can't expect comparable core for core performance as the architectures have different objectives. Thermals, power consumption and performance would all be significantly lower on existing mainstream ARM chips.
- kllrnohj 7y agoARM vs. X86 is just the instruction set. The instruction set plays almost no role in power / performance these days. Maybe once in a very distant past when an x86 decoder was a significant chunk of silicon, but not these days. So instead you'd need to ask how does Zen 2 compare to Cortex A76 or something like that. Which we don't know since we don't have the 15W Zen 2 mobile parts to benchmark yet.
