DailyTech - Intel Sheds Light on "Penryn" Enhancements
This website tells you the improvement that the upcoming 45nm processors will have. And the improvements is not only a die shrink like many AMD fanboys claimed. There will be many tweaks to the micro architecture of penryn to achieve greater performance at the same clock speeds as Conroe processors.
Here are some quotes from the the article in the above website
So this ^^ means that Penryn will not only have more cache, but Intel will aslo reduce cache latency, and Penryn features a 24-way associative cache.
Thats ^^ a good improvement
And thats not all !!

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.
So this ^^ means that Penryn will not only have more cache, but Intel will aslo reduce cache latency, and Penryn features a 24-way associative cache.
New to the Advanced Digital Media Boost technology is the inclusion of a new Intel SSE4 instruction set. SSE4 introduces 47 new instructions to improve performance of video accelerators, graphics building blocks and streaming load. Intel claims a 2x performance gain in video acceleration tasks. There are 14 new instructions for video accelerator performance enhancement. Intel improves compiler auto-vectorization performance with 32 new instructions.
Intel expects SSE4 optimizations to deliver performance improvements in video authoring, imagine, graphics, video search, off-chip accelerators, gaming and physics applications. Also new to Advanced Digital Media Boost is the Super Shuffle Engine. Intel's Super Shuffle Engine allows for shuffling unpacking, packing, align concatenated sources, wide shifts, insertion and extraction, and setup for horizontal arithmetic functions. Intel claims a “2x faster SSE shuffle instruction execution,†according to briefing documents.
Thats ^^ a good improvement
And thats not all !!
