There's more to Intel's next-generation processor family than the 45nm process node

Intel plans to unleash its Penryn family processors next quarter, shortly after AMD releases Barcelona. Penryn is the umbrella for all 45nm Core 2 micro architecture products, including quad-core Xeon Harpertown, quad-core Core 2 Yorkfield and dual-core Xeon, Core 2 Wolfdale processors.



On the surface, Penryn looks like die shrink of last year’s Conroe micro architecture, but Intel sought additional tweaks to the micro architecture to achieve greater performance at the same clock speeds as Conroe processors.

Intel improves existing Wide Dynamic Execution, Advanced Smart Cache, Advanced Digital Media Boost and Intelligent Power Capability, technologies that previously made its debut with Conroe and Merom.

Penryn enhances Wide Dynamic Execution technology with a fast radix-16 divider and improved Virtualization technology. With a fast radix-16 divider, the processor can process 4-bits per cycle instead of the 2-bits per cycle of Conroe – doubling the divide instruction capabilities. Intel VT technology receives enhancements that reduce virtual machine transition latencies by 25-to-75%.

Intel Advanced Smart Cache technology receives additional enhancements, besides the increased L2 cache. Penryn-based quad and dual-core processors will have up to 12MB and 6MB L2 cache, respectively. Intel reduces cache latency in addition to the larger sizes. Penryn features a 24-way associative cache, an upgrade from Conroe’s 16-way associative cache... More
