In July, the first Core 2 Duo Extreme Mobile X9100--a Penryn dual-core CPU--to show up at our labs debuted inside Micro Express's JFL9290 laptop. The PC World Test Center is still putting that machine through its paces (you can check out our assessment of its little brother, the Micro Express JFL9226, in the meantime), but the initial numbers are impressive. It dominated our WorldBench 6 tests, notching a score of 115 and posting decent frame rates in Doom 3 (47 frames per second at 1024 by 768 resolution, with antialiasing) courtesy of a 256MB nVidia GeForce 9600M GT GPU. The real speed king, though, is the QX9300 (a Penryn Quad Core)--and it's now out the door, launching this week.
Here's the breakdown on what they offer. The X9100 has a 3.06-GHz frequency, two cores, and a 6MB cache running at 44 watts. The QX9300 has four cores running at 2.53 GHz, with a 12MB cache at 45 watts.
The new chip's focus on gaming capability shows up in many ways, starting with the way it emphasizes design choices for dual discrete graphics cards in the system. Another example is the chip's automatic overclocking of RAM (and DDR3 memory). And don't forget Intel's claims of improved I/O read times with the upcoming X18-M and X-25M SATA Mainstream SSDs.
