Very unlikely. 64-bit is mostly an advantage if you have to use a lot of memory or are doing processing on actual 64-bit integers.
For the kind of software like Opera (and Firefox and Chrome), the additional registers in 64-bit mode help a little, but that tends to be offset by most pointers now being 64-bits and the L1/L2 caches hence being less effective.
- Egregore 14y agoOn my computer most memory hungry apps are browsers. And by the way I use opera to open a lot of tabs and it handles those very well (compared with other browsers)
- untog 14y agoRight, but 64-bit computing isn't a magic bullet that speeds everything up. As gcp stated, there are both benefits and drawbacks.
- mkup 14y agoThere are more registers in x64, so there may be some speed gain. Or a loss of speed due to larger pointer size and more frequent cache misses.
- moonchrome 14y agoRegisters, more instructions guaranteed (like SSE2) etc. It's up to the compiler to take advantage of that tough.
- gcp 14y agoDid you just repeat exactly what I said?
