I'm somewhat dubious of the performance claims from the switch to a 64-bit architecture. That doesn't seem like it has been a bottleneck for a lot of processes and applications on mobile historically, but I could be wrong. Can any devs offer any insight on whether the 64-bit switch could make a real difference at anywhere but super high-throughput operations like, as Epic demonstrated, swapping a huge amount of data into RAM?
- RyanZAG 13y agoThe performance claims are marketing speak: they say the new 64 bit CPU is now twice as fast as the old 32 bit CPU. But this isn't too strange, the previous 32 bit CPU was also about twice as fast as the predecessor to that one. So what he's actually saying is (1) the CPU is now 64 bit and (2) the CPU is faster than the old one. Seems a lot clearer when you split it up like that, yeah? It's clever use of language. (1) is useful for future proofing the iOS architecture for >4GB of RAM in upcoming devices and lets developers start compiling their apps now for 64 bit. (2) is just the usual improvements and faster clock speed that is obvious for a new generation of devices.
- devindotcom 13y agoYeah, I assumed that the big performance gains, comparable to previous proc updates, were due to just being a faster chip. The quotes were "up to 2x faster," which is of course not untrue but still a bit misleading. Hopefully a few benchmarks and real-world tests will bear out the actual differences.
