It's no secret that the P67 chipset that accompanied earlier this year the launch of Sandy Bridge processors does not really convinced. Between the bugs affecting the SATA part of the first copies and the artificial limitations imposed by the manufacturer, many users have patiently waited for the Z68 chip, announced for many months already.
With the integration of a heart graphics, PCI-Express controller and memory controller within the processor, chipset's role is now limited to the management of interconnections between the CPU and the rest of the system. Connected to the CPU by a bus DMI at 20 Gb / s, the Z68 and loads of USB and SATA controllers supporting respectively 14 USB 2.0 ports and 6 SATA ports (with RAID support 0, 1, 5 and 10), two SATA 6 Gbps.
The support of USB 3.0 is unfortunately not yet implemented. Eight PCI-Express 2.0 are also available. So here we find similar characteristics to the P67 ... The most interesting news of the Z68 are indeed elsewhere, in the example of overclocking. This chipset allows to overclock the CPU frequency and that of memory, but also that of the integrated graphics controller, which the P67 was obviously not able to do.
It becomes possible to enjoy the features of the engine QuickSync. Also new, the emergence of the Smart Response, or SSD Caching. The objective here is to use an SSD - a capacity of between 20GB and 64GB - as buffer between the HDD and the rest of the system. Performance in reading and writing should be substantially improved.
Intel take this opportunity to launch a DSS dedicated to this technology, the Intel 311 (Larsen Creek for short). In short, the Z68 chipset does seem to retain only the best chipsets H67 (management of heart graphic Sandy Bridge) and P67 (management of overclocking), while bringing the Smart Answer.
Finally, note that the majority of motherboard manufacturers have already announced that many cards Z68 models will benefit from the technology of Virtu LucidLogix. It was worth the wait, right?
