The notebook being used in this article is an Intel Lenovo ThinkPad T61. This notebook is configured with an Intel Core 2 Duo T9300, 15.4" WSXGA+ TFT display (1680 x 1050 resolution), NVIDIA Quadro NVS 140M discrete GPU with 128MB of video memory, 2GB of DDR2-667 system memory, 120GB 5400RPM SATA hard drive, and Intel 3945ABG 802.11g wireless. The notebook arrived with Microsoft Windows Vista Home Basic, but once it was benchmarked against WINE and CrossOver Games, that partition had quickly disappeared. For enterprise customers, Lenovo does offer the ThinkPad T61 pre-installed with SuSE Linux Enterprise Desktop 10.

With Intel being a strong supporter of open-source software and Linux (and the PM965 Express Chipset not exactly being new), it's to no surprise that this notebook had worked out of the box with Ubuntu 8.04 Beta and had presented zero issues along the way. With Ubuntu 8.04 Beta there were no ACPI or cpufreq problems with the Core 2 Duo T9300 "Penryn" processor.

The Linux 2.6.24 kernel with cpufreq had worked with all of the different Intel SpeedStep states for the T9300 of 2.5GHz, 2.0GHz, 1.6GHz, 1.2GHz, and 800MHz. With this mobile Penryn we had found its power switching to be much more aggressive then with an earlier Intel Yonah found on a Lenovo ThinkPad T60. While most of the time the two CPU cores were operating at the same speed, the CPU frequency was able to switch independently with the Penryn as can be seen from one of the screenshots above.

The other laptops we used for our Mobile Penryn comparison tests on Linux were a Lenovo ThinkPad T60 and ThinkPad R52. The Lenovo ThinkPad T60 packs an Intel Core Duo T2400 (1.83GHz) processor, 1GB of DDR2-533 RAM, 80GB 5400RPM SATA drive, and ATI Mobility Radeon X1400 128MB (15.4" 1400 x 1050 display). The Lenovo ThinkPad R52 was composed of an Intel Pentium M 750 (1.83GHz) processor, 2GB of DDR2-533 RAM, 80GB 5400RPM IDE drive, and an ATI Mobility Radeon X300 64MB (15.4" 1400 x 1050 display). All three of these laptops were running Ubuntu 8.04 Beta with the Linux 2.6.24 kernel.

As there are far more variables at play with the hardware then just the processor, we had limited our quantitative Linux benchmarks to Bootchart, LAME encoding, Ogg encoding, timed disk reads, Gzip compression, and RAMspeed. For those interested in the graphics performance capabilities of the ThinkPad T61 with the T9300 Penryn and Quadro NVS 140M, tomorrow we will be delivering those Linux results in another Phoronix article.
