company AMD plans to release the first processors on the basis of updated microarchitecture K8L, under the most optimistical forecasts not earlier than second half of 2007 (and, most likely, in first half of 2008), engineers continue to share willingly details about what innovations will expect us in the future cores. So, this week the corresponding information was received from AMD partners. The Most intriguing news became that the future desktop processors based on microarchitecture K8L, are compatible to work with existing Socket AM2 infrastructure, the future core will support DDR3 memory and HyperTransport 3.0.
as informs the source, perspective CPU which will be issued in Socket AM3 , with equal success can be applied for both Socket AM3, and in Socket AM2 motherboards.
so the support of perspective interfaces DDR3 SDRAM and HyperTransport 3.0 in K8L does not contradict with their compatibility with Socket AM2 motherboards. the integrated memory controller of those processors as informed earlier, will support DDR3 and DDR2 memory simultaneously. The choice of used type of memory will be determined by the motherboard. It is obvious, that in Socket AM2 platforms K8L begins to work only with DDR2 SDRAM.
Differently, to use all plus of K8L updating platform on Socket AM3 all is required. But compatibility Socket AM3 CPU with Socket AM2 motherboards will enable realization of a gradual upgrade and "step-by-step" advantage from all future of the microarchitecture. Actually, owners Socket AM2 platforms can update in the beginning only the processor, and then change othe motherboard and memory
processors Brisbane will not pass on Socket AM3 as they will be based on current microarchitecture K8. The first desktop CPU in Socket AM3 , obviously, become 4 core processors Greyhound and then dual core relatives planned for 2008.
