Fast... Only with 8 threads

I am highly skeptical of the preview and the "huge" performance improvement because so few of us are likely to see it. All the tests shown and that large percentage increase in performance were with heavily multithreaded processes that can take advantage of 8 threads. I seriously doubt that today's single and dual core games will get any noticeable performance improvement with Nehalem over Wolfdale or Yorkfield. Nehalem is planning for a heavily multithreaded future which is great, but for the games I play 2 extra threads (over a dual core processor) are useless let alone 6, and I doubt that any games will use 8 threads at Nehalem's introduction.

So what exactly in the preview are you skeptical of? There is nothing misleading here.

If you don't use programs to take advantage of good hardware well duh don't buy it.

Gaming isn't the only computer function and hey guess what, they didn't even preview gaming performance.

Besides the hyperthreading, there are many fundamental improvements to the cache, look-aside buffers, etc, not to mention the integrated memory controller and QuickPath.

Intel is claiming 10-30% performance improvement in single threaded applications.

From the article:

quote:
Cinebench shows us only a 2% increase in core-to-core performance from Penryn to Nehalem at the same clock speed. For applications that don't go out to main memory much and can stay confined to a single core, Nehalem behaves very much like Penryn.


That throws, for the moment, a bucket of cold water on my expectations temporarily. That apparently fits nicely within its cache and thus doesn't reveal the IMC benefit, or thats how the article made it sound, but still. Might have to wait until a formal review to be certain.

Even if clock for clock single-core performance doesn't go up much, I'll just have to console myself that it'll probably kick ass at Folding@Home's SMP client.

Well, considering that the current tested one is only working at single channel and the memory latency and bandwidth is worse than Core 2, the estimation by Intel for 10-25% single threaded improvement makes sense. But its not showing that now. And the multi-threaded results will go up even further...
