The Sony VAIO VGN-CR11SR/P is based on an Intel Core 2 Duo T7100 processor with a clock rate of 1.80GHz (65nm Merom core with 2 megabytes of shared L2 cache). The FSB frequency is 800MHz.
Intel Core 2 Duo T7100: cache-memory
The Core 2 Duo T7100 supports Intel’s 64-bit extensions to the x86 architecture and also features Intel Wide Dynamic Execution technology which means more decoders and execution units in the CPU core. The speed of processing SSE and FP instructions is increased, too.
Besides Intel’s traditional Enhanced SpeedStep technology that gives the notebook’s software and BIOS the control over the CPU frequency multiplier (to reduce it under low loads), this CPU supports Dynamic Power Coordination (the power consumption of the cores can be independently adjusted depending on the current load; one core may even slip into Deep Sleep mode with the lowest power consumption possible), Dynamic Cache Sizing (unused segments of the CPU cache can be turned off to save power), and FSB Frequency Switching (the FSB clock rate is automatically lowered at low loads).

This implementation of the Santa Rosa platform also incorporates an Intel PRO/Wireless 4965AGN adapter and an Intel Crestline GM965 chipset. The 965 series chipsets support a FSB frequency of 800MHz. The GM965 offers a PCI Express x16 interface for an external graphics card and also features an integrated graphics core called Intel Graphics Media Accelerator X3100. Connected to the North Bridge via a special-purpose Direct Media Interface, the South Bridge (ICH8-M) supports three Serial ATA-300 ports, ten USB 2.0 ports and Intel High Definition Audio. It also offers six PCI Express x1 lanes to connect external devices. For more information about the platform, visit the manufacturer’s website.
GMA X3100 is the first graphics core from Intel to support shaders on the GPU. As a result, the new integrated chipset features improved performance and compatibility with 3D applications, particularly with Windows Vista’s Aero interface. The X3100 can also support DirectX 10 using the recently released driver. The new core is clocked at a frequency of 500MHz and incorporates 8 unified shader processors for 3D rendering as well as for video playback acceleration. Thanks to them, the X3100 provides hardware acceleration and post-processing for video content in MPEG-2 and WMV9 formats. The core doesn’t support the new compression standards H.264 and VC-1 (Blu-ray and HD-DVD), though. Besides higher performance, the new graphics core has acquired more advanced power-saving features, mostly meant to reduce the consumption of the LCD panel which is the main power consumer in a notebook together with the CPU. The X3100 supports Display Power Saving Technology 3.0 that is automatically adjusts the brightness and contrast of the screen to reduce power consumption yet keep the image quality high. The Display Refresh Rate Switching technology can be used to reduce the refresh rate of the screen when the notebook works on its battery.
The notebook comes with a Toshiba MK1234GSX hard disk drive (2.5” form-factor, 5400rpm spindle rotation speed, 120GB capacity, ATA-7 interface) and a Matsushita UJ-850S DVD-burner with the following speed characteristics:
- CD-R – 24x
- CD-RW – 16x
- DVD-R DL – 4x
- DVD-R – 8x
- DVD-RW – 6x
- DVD+R DL – 4x
- DVD+R – 8x
- DVD+RW – 6x
- DVD-RAM – 5x
- CD-ROM – 24x
- DVD-ROM – 8x
The CR11SR/P works with DDR2-667 SDRAM, the fastest memory available on the Santa Rosa platform. Both memory slots are occupied by 1GB modules. This is in fact the highest amount of memory the notebook can support. The memory works in dual-channel mode as reported by the CPU-Z tool.
Dual-channel memory mode
I measured the temperature of the hottest spots on the notebook’s surfaces with an infrared thermometer after it had worked for half an hour in Battery Eater Pro 2.60 (the ambient temperature remained constant at 23°C during this test) and got the following numbers:
- LCD panel – 37°C
- Keyboard – 32°C
- Bottom panel – 33°C
- Vent hole – 36°C
The temperature parameters are good. The notebook is unlikely to overheat.
