In addition to our usual suite of performance and power testing, we also ran the Asus K42F and HP’s Pavillion dv4-1555dx through MobileMark 2007’s Productivity suite. Having switched out our 160GB Intel SSD in favor of a clean 500GB Seagate Momentus 5400.6 with the picky BAPCo app installed, we saw the following battery life rating and performance qualification scores:
| Battery Life Rating | Performance Qualification | |
|---|---|---|
| Arrandale (Asus K42F) | 285 minutes | 234 |
| Penryn (HP dv4-1555dx) | 235 minutes | 209 |
Clearly, the Asus wins in both performance and longevity, but let’s also take into account differences in battery capacity between these two mobile platforms. Asus outfits its offering with a 63Wh Li-Ion battery pack (14.4V, 4.4Ah), while HP employs a 47Wh power supply (10.8V, 4.2Ah).
With a significant advantage in energy storage, it’s really no wonder Asus was able to walk away with this one. Let’s normalize the results a bit to see whether the win stands up, all things equal.
| Minutes | Watt-Hours | Minutes/Wh | |
|---|---|---|---|
| Arrandale (Asus K42F) | 285 | 63 | 4.5 min/Wh |
| Penryn (HP dv4-1555dx) | 235 | 47 | 5 min/Wh |
When you do the math, the Montevina-based HP system actually lasts longer per available Wh of energy available to it, but because HP ships such a small battery, the notebook doesn’t end up lasting as long. Thus, while the previous page really demonstrated how far Intel has come in bringing down idle power consumption, distilling down the numbers reminds us that there’s a price to be paid for performance. There’s a fair chance that, if we were to turn off Turbo Boost and re-run MobileMark or re-chart a PCMark Vantage run, we’d see lower peak power use and the same low idle consumption. Unfortunately, Asus’ EFI setup doesn’t provide access to such an option, so it’ll have to remain conjecture for now.

- Conclusion
Performance is good but I'm hoping for a viable update to the CULV offerings of yesterday.
Keep it up intel. I do hope that AMD will release some new chips that will be able to compete with intel offerings.
That chops them completely out of the mobile graphics market for the masses ... Intel will pay the RIGHT OEM's some "adjustment" just to make sure their "Strategy" is right to ensure AMD's mobile market is thin and restricted to the backwaters of Bejjing.
Have a look at Page 8, where HD Graphics is compared to the previous-generation GMA in Vantage and WoW. You're not going to get much else out of this, to be honest...
Also the integrated graphics can barely match the 9400m that is 1-2 years old.
The battery life is the same or worse...
What is so great about this chip?
Personally I'm not at all impressed and find it a step side ways or even backwards.
The integrated graphics do suck, but at least now we have a choice in some laptops where we can switch from the integrated to dedicated, saving battery life when needed and boosting performance where needed. It adds flexibility basically, I'm sure Intel was aiming more for that rather than performance in 3D games.
What I really want to see is the ULV versions of this chip. I'm hoping whenever they start coming out, it'll push down the prices of older Ultra-Portable laptops around the 12-14" sizes. Certain ones with the C2D SU7300 and 4GB of RAM can be found for around $550 today. If these prices go down far enough, netbookks will be obsolete in my mind.
