Somebody have something I can read to better understand just how RHT and Core Multiplexing work? I know what they do, have a vague idea of how they do it, but still trying to learn more.
I have to explain it to someone, and all I know is that it works by sending every other instruction to the second core. According to said person, thats not possible.
There was an interesting tidbit on the main page today. It would appear that Mutliplexing is simply turning of the second core and using it's L2 cache to double the cache of core 1. Now I rather suspect that this will not give the benefits that reverse HyperThreading can. With AMD's approach you still have use of the additional L2 cache, plus the additional core.
Mind you, if Intel can turn off 1 core minus the cache, I rather suspect they'll be able to easily use reverse HT as well. I just can't see that using two cores is harder than turning one off and combining the cache... I can't see why they've done this in the first place actually. Perhaps they're thinking their chip is fast enough already and just want to kick AMD's *** in the power consumption area
