Intel Westmere: Six-Core in 32nm in 1H/2010
- Thread starter Shtal
- Start date
With that L3, the addition of the IMC and other things intel piled in, that's likely.
Nice! I thyink I'll wait for this rather than going for Nehalem as soon as it launches. I didn't really feel Nehalem was enough of an upgrade over my exisiting dual core conroe to justifiy it. Especially with the talk of it not being much faster in gaming (both on a per core basis and the fact that games don't scale beyond 2 cores very well).
Clock for clock Nehalem is about ~20% faster then conroe core2.
-OR- Unless if this is true fact!! I would guess 30% faster clock for clock.

Yes, but most of that is due to the MC being integrated. What about non-memory bandwidth bottlenecked apps?
Conroe or Penryn? Since Penryn is already around 5-10% faster then that would only make Nehalem 10-15% faster than an equally clocked Penryn. Not much when you consider what they have added.
I read that Intels focus with Nehalem was not desktop performance but on server performance (where it will likely wipe the floor with Penryn).
Still, if you meant Penryn and your second link is accurate then a 30% performance boost would be nice. I think I'll just wait and see how it pans out. There's certainly nothing even my modest 2.4Ghz C2D can't handle at the moment so I might even hand on for Sandybridge. AVX looks sexy
Does anyone know offhand - can Nehalem's L3 be partitioned or is it just an aggregate chunk of cache accessible by all cores?
One thing people are not remembering about Nehalem - its new cache hierarchy includes a new level (L3) which has latency, and is inclusive. Either they've decided "to hell with latency, we want bandwidth and threads" or their simulated cache hit rates are through the roof and effective latency is actually down so it's irrelevant.

Nehalem's focus is on the future, and that means its a bandwidth monster with a multi-threading specialty, let's say.
I'm holding out for Westmere at least, unless I can afford to build a DP Gainestown system (the next skulltrail) that is
In my future PC universe (in my head) I can see a 2MB L2 per core, 8 core/16 thread part with 16MB or more L3. Oh, and approx. .5TFLOPs @ 4GHz too

So, AMD will have a 12 core with 1 thread each core (Magny Cours) and Intel 6 cores with 12 threads. Are these equilvalent aproaches, because they have the same number of threads? They are planned to be released at the same time (http://www.techreport.com/discussions.x/15474 )
It could be Conroe or Penryn - depends on the application, sometimes extra cache on Penryn not needed; also, you could consider SSE4 not supported by older applications
No quad core Westmere!
It seems there won't be a 4 core version of Nehalems successor at all.
When Westmere does launch in late 2009, it will be in dual core versions only.
Later in early 2010 we'll get a 6 core varient of Westmere but I expect that will be a very high cost part. According to Anandtech, we won't see the re-introduction of quad cores until Sandybridge.

Thats a very good point actually, I hadn't considered that. I wonder how the L3 cache will work then?
Thiat actually makes me more interested in picking up an i7 now. Especially since they're unlikely to scale much, if any faster than 3.33Ghz this year.
