Real Life Mobile Penryn vs Merom Benchmarks
Anandtech was able to provide a direct comparison between the two processors:
Intel sent us two Dell Latitude D630 notebooks, identically configured, with one variable: the CPU. In one D630, we had a Core 2 Duo T7800, which is a Merom based chip running at 2.6GHz with an 800MHz FSB and a 4MB L2 cache. The other D630 came equipped with a new 45nm Core 2 Duo T9500, also running at 2.6GHz/800MHz but with a larger 6MB L2 cache.
With just the processor change alone, the new Penryn laptop offered 5-10% more battery life on their benchmarks. Meanwhile, the new processor saw 1 - 8% speed boosts on common tasks, and up to 40% improvements in applications that support the SSE4 instruction set.
Apple's MacBook Pro is currently available with Merom chips at 2.2GHz, 2.4GHz and 2.6GHz speeds. The last major revision of the MacBook Pro was in June of 2007.

(View all)Here is also hoping Photoshop adds SSE4 support for common filters.
The notable thing beside better power usage is far better likelihood of deeper back-end price drops due to far smaller die sizes. Given Apple uses long term supply agreements with back end discounts, this product was designed more for manufacturability than even for features, which are strong enough indeed.
Apple is winning the vendor-supplier game, and Intel is reaping the benefits.

Penryn is a new 45nm chip.
yea santa rosa is a subgroup of the merom processors.
Penryn is a new 45nm chip.
i know what penry is. Though santa rosa chips are already 45nm and use the high k method that im guessing was carried over to penry as well
Is Vista fully 64bit?
Is Vista optimized to handle multiple processors/cores?
Can it throttle processor utilization and power consumption?
Sorry, I'm fulla questions and sorta feel like 10.5.2 will address some of these issues.
Penryns will show even better improvement with OS X.
Meanwhile, the new processor saw... 40% improvements in applications that support the SSE4 instruction set.
What applications/types of applications take advantage of this?
