Intel Sheds Light on Penryn Processor Improvements

Intel plans to release Penryn next quarter, after AMD
will release its Barcelona processors. Penryn is a “refined” version (45nm norm) of the Conroe microarchitecture, but the company has found additional ways to improve it so that Penryn’s performance level is higher than that of Conroe at the same frequency.

Improvements have been made to Wide Dynamic Execution and Advanced Smart Cache technologies,
Advanced Digital Media Boost and Intelligent Power Capability, which are for the first time
appeared in the processors of the Conroe and Merom families. As previously reported, Penryn
“knows how to do” fast division (“divisor” radix-16) thanks to processing up to 4
bits per cycle, and has improved support for virtualization technology (Intel
VT) – VM latency reduced by 25-75%.

2- and 4-core Penryn processors will receive 6- and 12-MB cache
L2. In addition, reduced latency in cache memory.
Caching is also improved due to 24-channel associativity (versus 16-channel
for Conroe processors).

Advanced Digital Media Boost has been updated thanks to
set of “multimedia” instructions Intel SSE4, of which there are 47. They are like
supposed to improve the work with streaming data, 14 new instructions will speed up
video processing (according to Intel, twice (!)) and
work with graphics. The 128-bit Super Shuffle Engine will enable
full shift in one cycle, improving the performance of SSE2 instruction sets,
SSE3 and SSE4, which actively use unboxing and packaging operations.

processors based on the Penryn core will receive new energy saving technologies, thanks to
why laptops built on them can run on batteries longer. IN
the mobile version of Penryn added the so-called deep sleep mode, in which
the processor reduces the voltage, even more than in the C4 state, and also turns off
cache of the first and second levels.

For workstations and servers, Penryn will be released in
Harpertown. Penryn will be based on Xeon DP, MP and UP processors,
which support FSB 1333 MHz. However, the last
already more focused on a higher frequency – 1600 MHz. 4- and 2-core
Penryn-based Xeon will have three thermal packages: 50, 80 and 120 watts will
typical for 4-core Xeon (Harpertown), and 40, 65 and 80-W
TDP will characterize Xeon (Wolfdale).
