Notice any similarities between the Hewlett-Packard Voodoo Envy and its thin rivals, the Apple MacBook Air or ThinkPad X300? Yes, they're all very thin. But look inside and you'll see more common features.
To deliver reasonable processing power at low power the Voodoo Envy opted for the same special low-power processors used in the Air: the Intel SP7700 and SP7500.
You won't find these processors listed on Intel's processor pricing page. They were designed originally for the MacBook Air and use a special 22mm x 22mm package and have a thermal envelope of only 20 watts at 1.8GHz and 1.6GHz. Typically, Intel processors running at those speeds have a TDP (Thermal Design Power) of 35 watts.
Correction: The ThinkPad X300 uses an Intel SL7100 not an SP processor. It comes in the same small package as the SP processors but runs at a lower clock speed--1.2GHz--and uses less power: 12 watts versus the SP's 20 watts.

"Montevina" Centrino 2 processors coming out later this year will include low-power models such as the SL9400 and SU9400, running at 1.86GHz and 1.4GHz with a TDP of 17W and 10W respectively. One processor, the SU3300, will have a TDP of 5.5W.
New versions of the SP "small form factor" processors are also expected later this year. Future versions of the Envy and Air will likely use these Montevina processors.
This isn't where the silicon similarities end. The Envy, like the Air and X300, uses Intel X3100 integrated graphics and offers either a 64GB solid state drive or 80GB hard disk drive (4200RPM), just like the Air.
Finally, though not related to silicon, all three notebooks have a similar form factor: 13.3 inches. All in all, making for strikingly similar designs in many ways.
The MacBook Air, IdeaPad U110, and ThinkPad X300 are the three hottest ultraportables out there. They all sport unique styling outside. And Intel blue inside.

(Credit: Lenovo)Styling and design are now so crucial in notebooks that when a model arrives in pink the color change alone is news.
Ditto for the styling imperative for some of the sveltest, lightest, and most impressive of notebooks: the Air, X300, and just-released U110.
Scratch the surface (or lift up the keyboard in this case), however, and you'll find that their unique exteriors house similar Intel core electronics.
Does this have anything to do with nefarious strong-arm tactics on Intel's part? Or just that AMD and Nvidia don't have competitive offerings in this space? The evidence points pretty convincingly to the latter.
Graphics--an increasingly important differentiator in any computer--is the same across all three notebooks: Intel X3100 integrated graphics. No Nvidia option here. No AMD-ATI. Intel across the board. The reason for this is strictly practical. For heat and power consumption purposes, these ultrasmall designs cannot accommodate an extra graphics processor. (It should be noted also that Nvidia and AMD-ATI integrated graphics are typically not used in ultra-low-power designs.)
The processors are all Intel too with some differences. Again, a practical consideration since AMD doesn't offer ultra-low-power x86 processors with relatively high performance.
The newest 11-inch U110 IdeaPad has gone with the Intel Core 2 Duo L7500 processor. It runs at 1.60GHz and integrates 4MB of cache. The low-voltage L7500 has a thermal envelope (referred to as Thermal Design Power or TDP) of only 17 watts. Much lower than the typical 35-watt Intel mobile processor. AMD mobile processors have similar above-30-watt thermal envelopes.
The 13.3-inch ThinkPad X300 uses the Core 2 Duo SL7100 LV chip running at 1.2GHz. This is a 60 percent package "shrink" of Intel's original Core 2 Duo design and draws a mere 12 watts. Why the shrink? These variants consume less power compared to larger counterparts, giving laptops longer battery life.
The Mermon package shrink featured in the X300 debuted with great fanfare in the MacBook Air. The Air uses 1.6- and 1.8-GHz versions of this Intel chip with a 20-watt TDP.
Similarities between ultraportables extend beyond Intel to storage options too. The Air, X300, and U110 all offer either 4200RPM hard disk drive options or 64GB solid state drives. The 4200RPM drives in the U110 and Air can be real performance bottlenecks if a user pushes the usage envelope. The X300 only comes with a solid state drive.
The solid state drives, while expensive, have proved to be able performers, even bettering high-end hard disk drives in some benchmarks.

The X300 ThinkPad, which starts at $2,900, is one of the hottest--and most expensive--notebooks on the market now. The Apple MacBook Air is another. They both come with solid-state drives (SSDs) that perform better than standard magnetic hard-disk drives. And the X300's outpaces a 7200rpm hard drive by a long shot, according to review site Hot Hardware.
In a test, the X300's SSD "performed 2.75 times faster than the Dell XPS M1730 running dual 7200rpm drives," the review said. That's not all. "The X300's performance was nearly 4.9x faster than the Asus U6S" with a 5400rpm 160GB hard drive.
Lenovo puts it this way: "Faster boot and application load times, extra durability, and longer battery life." You can add stratospherically higher unit price, but the price impediment will diminish over the next 12 months.
SSDs are based on flash memory chip technology and have no moving parts. Hard drives, in contrast, use read-write heads that hover over spinning platters to access and record data. With no moving parts, SSDs avoid both the risk of mechanical failure and the mechanical delays of hard drives. Therefore, SSDs are generally faster and more reliable.
