[NEW STUFF] Intel LGA1155

[JumpingJack]

so you think there wont be any apps that see no perf/clock improvement on sb? i think thats overly optimistic...

even if its 15% faster per clock, thats still not a reason to upgrade... 15% higher ipc PLUS higher clocks, PLUS turbo, PLUS power savings in idle and few cores loaded... that would really be something you cant ignore... it would turn all current laptops into outdated "last year" equippment

Out of hundreds of apps, sure one, two a few maybe will not be sensitive to the changes, but on the whole the majority should look pretty good I suspect. The IPC gain won't be eye bulging great but it won't be anaemic either. And I am sure there will be those one or two cases where the fanboys will point to the result and say 'see, it sux' ignoring the 80% to 90%+ population where the gains are good to great ... just like the chorus of 'Nehalem sux as a gaming CPU' we saw when it first was introduced. Heck, SB will show no gains in GPU limited games and this will be a common fanboy claim I am certain of that.

We know so little at this point, what we do know is that Intel is reworking the interconnect (ring bus), adding a load port, and bringing down cache latency, the rest is in a grouping 'entire architecture is reworked'.

My guess is that it is going to 5 issue and that they will widen the execution window, this will have two main effects -- single threaded performance (IPC) will see a nice pop (say 10% or so, not more than 15% I suspect), but HT situations will see a real improvement with a wider core, so heavy multithreading may show even better gains.

After 5-issues, however, IPC gains (in general) start to fall off, there is just not enough ILP to push it much futher, I have a few nice papers on the topic.
