[NEW STUFF] Intel LGA1155

[saaya]

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 ...

well it depends... is those 2 apps it doesnt scale at all in are very very common, then... whats the point of some synthetic benchmarks or professional tools scaling nicely if close to nobody uses them
thats how it was with SSE improvements in the past, so im curious what we will see with avx now...

just like the chorus of 'Nehalem sux as a gaming CPU' we saw when it first was introduced.

i cant remember anybody saying it sucks for games... it kinda sucked for gamers cause it was a lot more expensive than c2d and c2q but offered the same perf and even slightly worse in some games...

HT situations will see a real improvement with a wider core, so heavy multithreading may show even better gains.

that might be interesting for servers, but laptops? heavy multithreading on laptops?

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.

link pls!

amdahls law is the theoretical limit... most people forget that its far from feasible to write code that gets even close to that limitation in most situations... it just doesnt make sense... its possible to multithread most of the code we use, but does it make sense and will it actually be done? thats something intel and amd dont like to think about, as it ruins their strategy of just bumping out more and more cores in the future as a way to boost performance. they keep upping the core counts and hope that at some point, SOMEHOW, the infra structure will just MAGICALLY pick up and make use of all the cores, and that SOMEHOW, SOMEDAY a magical killer app shows up that makes use of lots of cores...

so im glad to hear intel focussed on ipc with SB and didnt just give us 50% more cores... cant wait to see it in action!
