It wouldn't matter if it was 20%.Originally Posted by informal
Nehalem improves performance on average over Penryn by 20-30%, and in code where 8+ cores are supported (allowing for SMT to work) the difference can be more like 30-40% or more. Deneb needs to be a solid 10-15% faster than Agena to equal the performance of Penryn.
And no I don't say that with happiness, although I can't wait to get my hands on a Nehalem system. It's not good at all that there is going to be such a wide gap in performance. But there's not much anyone can do about it except hope that AMD is more competitive in the future and with Bulldozer than they are now.
And outside of a very few people, nobody in this thread is an Intel fanboy. Most of the people praising Nehalem right now were laughing at how terrible the Pentium D was and praising the Athlon 64X2 just three years ago.
