The G70S is based on an Intel Core 2 Duo T9300 processor with a clock rate of 2.5GHz (45nm Penryn core with 6 megabytes of shared L2 cache). The FSB frequency is 800MHz.
Intel Core 2 Duo T9300: cache-memory
Like the previous, Merom, core, the Core 2 Duo T9300 supports Intel’s 64-bit extensions of the x86 architecture (EM64T), so you can install a 64-bit OS on the notebook.
Besides Enhanced Intel SpeedStep technology that can reduce the CPU multiplier under low loads), the Penryn core 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), FSB Frequency Switching (the FSB clock rate is automatically lowered at low loads), and Intel Dynamic Acceleration (this technology increases the frequency of the operating core in single-threaded environments; this is a kind of dynamic overclocking).
The notebook features the Intel Crestline GM965 chipset which offers a PCI Express x16 interface for an external graphics card. The South Bridge is the ICH8-M chip.
The Santa Rosa Refresh platform is made complete by the Intel Pro/Wireless 4965AGN adapter that supports 802.11a/b/g as well as the newest 802.11n. The latter standard is yet under development but already supported by a number of devices such as Wi-Fi cards, access points, routers, etc. It provides a data-transfer rate up to 300Mbps.
The G70S comes with two GeForce 8700M GT graphics cards. This card is based on the 80nm G84 core clocked at 625MHz and has 512 megabytes of dedicated GDDR3 memory with a 128-bit interface. You can disable SLI mode and use one card only to save power – this can be done in Nvidia’s Control Panel (the notebook will require a reboot for the changes to come into effect).
The notebook is also equipped with two identical hard drives WDC WD3200BEVT (2.5-inch form-factor, 5400rpm spindle rotation speed, SATA interface, 320GB capacity). It also features a Matshita BD-CMB UJ-120 BD-drive that can read Blu-ray media, and read and burn CDs and DVDs.
The notebook supports DDR2-667 SDRAM, the fastest memory available on the Santa Rosa Refresh platform. The memory subsystem works in dual-channel mode as reported by CPU-Z. The G70S comes equipped with the maximum amount of memory it can support.
