Penryn for all Santa Rosa?

Hello guys

Just got a newsletter from Zepto saying 6625WD will start shipping with the new Penryn CPUs.

My question: Will these work in the 6x24WD notebooks, I mean it is the same chipset as in 6625WD so why would'nt it?

The only issue is that the Penryns comming in Q3 with the 1066MHz bus will not be supported?

Will the Penryns ONLY work with Vista, sound a bit odd, anyone knows why?

Would you go for 3 or 6MB cache?

 

We have not completed Tests with XP yet but we have fully test with Vista so that is why we are putting the Vista only signs up currently

The Penryn CpUs will be available for the 6224/6324 models and you can see this if you look at the Danish,UK or Australian website

 

I just wanted to add that you are completely right about that it's only the 800MHz FSB Penryns that will work with Santa Rosa.
Or, the other ones may work, but you're not going to get full speed them.

Both the 3MB and 6MB versions will be offered.

 

Which size cache?

I have a theory (unproven) that more cache means more power leakage, so if battery life is a concern then the 6MB cache may be worse than 3MB. In other respects 6MB should boost performance.

I wouldn't spend money to upgrade an existing CPU to Penryn. I'll be saving my money for when the 2008 models arrive with the next Intel chipset (in the hope that Intel manages to address the power consumption problems and give good performance and good battery time).

Thank you all! I am considering a Penryn CPU, the SSE4 looks interesting to me. I also want to have a CPU with more cache then the 2MB I have now.
As far as I have been thought, the cache memory is one of the most important things for the performance of a CPU.

John Ratsey: You are probably right but I think it is not that huge difference.
For example a 2GB RAM module consumes more power then a 1GB
And 2x512MB consumes more then 1x1GB. And this is quite many more memory cells then in a cache memory. On the other hand is the cache faster and more used.

I have never heard of anyone reporting dramatic changes in battery life regarding different cachesizes and different memory modules.

 

In games, going from 2mb to 4mb cache only shows 8-10% performance increase at max! I remember that in a review @ Tom's Hardware
And this test was done with many games

 

Hmm I think I hold my horses for a while and wait for some benchmarks

 

The main performance gain of more cache is during multitasking. (Running many applications at the same time)

The CPU then have access to more frequent needed instructions and data.

So actually I think some extra cache would do me good
