In October we witnessed the launch of two AMD desktop families, based on their latest "Piledriver" microarchitecture. AMD released budget and mid-class Accelerated Processing Units on October 2, followed by high-performance FX microprocessors on October 23. Also this quarter, the company will introduce even higher performing "Piledriver" server CPUs, including Opteron 6300 series for quad-processor servers, and 4300 series for dual-processor systems. In the past day, AMD published details of 6300 family in the "Opteron 6300 Quick Reference Guide" (please see the link at the end of the article). The guide confirms specifications, that we posted back in October, and provides extra information, such as Turbo Core frequencies.
Opteron 6300 lineup consists of a mix of quad-core, 8-core, 12-core and 16-core SKUs, operating at frequencies from 2.3 GHz to 3.5 GHz. Standard features of 6300 microprocessors are 16 MB L3 cache, 4 HyperTransport links, and quad-channel memory controller, supporting up to DDR3-1600 memory. The size of L2 cache on these chips depends on the number of cores, ranging from 4 MB on quad-cores to 16 MB on 16-core models. Most Opterons feature Turbo Core technology, that can boost clock rate by a few hundred MHz, when all cores are operational, or even higher when some cores are idle. The only CPU in the series, that does not support Turbo Core technology, is Opteron 6308, although it could because the 6308 is already clocked higher than any other Opteron SKU. Turbo Core feature on energy-efficient 6366 HE can "overclock" it by as much as 1.3 GHz. The Turbo technology is less aggressive on the rest of the lineup, bumping the stock speed by 300 MHz - 400 MHz for all cores, and by 500 MHz - 900 MHz for half of the cores. Thermal Design Power of Opterons is 85 Watt for energy-efficient "HE" parts, 115 Watt for mainstream parts, and 140 Watt for high-performance "SE" processors.
Opteron 6300 family may launch on November 14 at SC12 conference in Salt Lake City, Utah. The prices of new microprocessors are not known, however the Quick Reference Guide states that "AMD Opteron 6300 Series pricing will be approximately 10% higher than AMD Opteron 6200 Series". As an example, the document provides prices for the fastest 16-core model with 115 Watt TDP. Opteron 6278 was priced at $988, while its replacement, Opteron 6380, will be $1088. Although new parts are priced higher, AMD claims that the 6300 products will have better price/performance ratio due to significantly increased performance.
