AMD Phenom II Triple-Core Mobile N870 - HMN870DCR32GM
Specifications
At this time, December 2010, AMD Phenom II N870 is the fastest mobile
microprocessor with three cores. The processor is based on enhanced
K10 microarchitecture, and combines 4 cores (one of them is
disabled), and DDR3-capable memory controller on one die. The N870
operates at 2.3 GHz, or 100 MHz and 200 MHz faster than earlier N850
and N830 models from the same family. The triple-core Phenom II
employs two-level cache architecture, where each CPU core includes 128
KB level 1 and 512 KB level 2 caches. Being a high-performance
microprocessor, the N870 includes all features that can be found in
other Phenom II models:
- Accommodates full 128-bit Floating Point Unit, which results in
better SSE performance
- Has increased memory bandwidth due to faster DDR3-1333 memory
support. This ultimately translates into higher performance in
memory-intensive applications.
- AMD64 instruction set extension allows this CPU to run 64-bit
operating systems.
- Enhanced Virus Protection prevents computer virus infections by
blocking certain types of exploits.
- Virtualization technology speeds up execution of user and system
software in virtual environments.
AMD Phenom II N870 CPU contains PowerNow! technology, as well
as several other low-power features, which, combined with processor's
low frequency and presumably low core voltage, helps this model to
achieve 35 Watt power rating. The Phenom II N870 is manufactured in
638-pin micro-PGA package, that requires socket S1. The processor fits
all variations of socket S1, but works only in S1g4 revision of the
socket.
Common perception "the most expensive processor performs the
best", which more often than not works for desktop CPUs, is not true
for mobile AMD microprocessors. While triple-core N870 will outrun
dual-core Phenom II or Turion II counterparts in multi-threaded
applications, they will not be as good in single- and dual-threaded
tasks, and you may end up not just wasting your money, but also getting
worse performance. Therefore, be careful when choosing this processor
for new laptop, or as an upgrade CPU for existing laptop. An easy way
to determine, whether the Phenom II X3 will work for you or not, is to
run your favorite applications on a multi-core computer, and watch
closely CPU usage for all cores. The Phenom II N870 should be good if
the system frequently uses more than two cores.

AMD introduces new mobile microprocessors
Jan 05, 2011: In the past months we posted a series of articles dedicated to
upcoming refresh of mainstream and ultrathin 2010 mobile platforms. If
you followed the stories then you may know that a number of not yet
released processors was spotted in specifications of Acer, Dell, HP
and Lenovo notebooks, and some of these notebooks already materialized
in retail stores. Today, AMD added new mobile models to 2010
AMD Mainstream Platform and 2010
AMD Ultrathin Platform pages, and updated
AMD product
pages as well.
HP service manual reveals new AMD mobile processors
Dec 16, 2010: Yesterday we published a story revealing not-yet officially
released Phenom II Triple-Core N870 microprocessor in Dell Inspiron
M501R notebook. We suspected that that processor would be a part of
future refresh of AMD mainstream "Danube" platform.
Today we found more mobile processors from the upcoming refresh.
Hewlett Packard recently updated
"Maintenance
and Service Guide" for Compaq Presario CQ42 and HP G42 notebooks,
and added unannounced AMD model numbers and their brief specifications.
Dell China ships Inspiron 501R with Phenom II N870 CPU
Dec 15, 2010: As the launch of Intel mobile Sandy Bridge microprocessors is
getting imminent, we expect that AMD will respond to it with new
versions of their low-power and mainstream mobile processors. Earlier
this week we published two stories covering new models from AMD
Ultrathin 2010 platform, Athlon II Neo K145, and Turion II Neo K645
and K685. AMD mainstream 2010 platform is getting refreshed too, and
one of the new processors for that platform is a triple-core
Phenom II N870.
