Intel releases Xeon E5-1428L processor

Earlier this week we reported on newly released Pentium 1405 microprocessor, that we spotted in Intel's ARK product database. The Pentium, destined for single-processor systems with socket 1356, has two CPU cores, and supports Turbo Boost and all other Sandy Bridge-EN technologies, but Hyper-Threading. Shortly after that report we learned about another socket 1356 CPU, Xeon E5-1428L, launched by Intel.

Xeon E5-1428L is a hexa-core (6-core) processor with 1.8 GHz clock speed and 15 MB L3 cache. The CPU incorporates Hyper-Threading feature, which allows the chip to handle up to 12 threads at once. Turbo Boost is disabled on this SKU, however all other Sandy Bridge technologies, like VT-x/VT-d virtualization and Trusted Execution, are enabled. Intel E5-1428L integrates triple-channel memory controller, that works with DDR3 memory up to DDR3-1333. Intel E5-1428L sports lower 60 Watt Thermal Design Power than majority of other 6-core Xeon CPUs. Like Pentium 1405, the Xeon uses socket 1356, and doesn't support multiprocessing. Intel's product database states that the E5-1428L was launched in the second quarter 2012, although we haven't seen any references to this chip on Intel's website before this week.
