AMD Athlon II P320 is a budget mobile microprocessor from Danube mainstream platform. The Danube platform, which consists of AMD M880G chipset and a variety of V Series, Athlon II, Turion II and Phenom II branded models, was launched in May 2010.
AMD P320 processor is built on 45nm enhanced K10 micro-architecture, and implements all of its most important components:
- Two CPU cores, with 128 KB level 1 and 512 KB level 2 caches per each core. The cores support all standard K10 features, such as Enhanced Virus Protection and Virtualization, and incorporate all extensions to instruction set, including AMD64, and streaming SIMD instructions up to SSE3 / SSE4a.
- On-chip memory controller, which is used to access on-board DDR3 memory.
- 1.6 GHz HyperTransport link is used to communicate with other on-board and add-on components.
The Athlon II P320 processor operates at 2.1 GHz, and, thanks to PowerNow! and other low-power features, has low 25 Watt Thermal Design Power (TDP). The microprocessor is manufactured in socket S1-compatible package. Please note that the AMD P320 is electrically compatible only with the S1g4 version of that socket.
Compared to V series microprocessors, the Athlon II P320 offers the same TDP at about the same clock frequency, while having an extra CPU core. For this reason AMD P320 may be used as a cheap upgrade for V series CPUs. While replacing V series processors with this Athlon II model won't result in better per-core performance, overall system responsiveness is going to be better, and performance in some multi-threaded applications will be almost twice higher than on V-Series chips.
Upgrading the AMD P320 on most laptops shouldn't present any
problems as long as you're able to disassemble the laptop and get to
the CPU. Upgrading to faster mobile Athlon II processors is not worth
it, as the difference in performance won't be noticeable. Turion II
series of CPUs can be considered as a not overly expensive upgrade
option. Not only these models have higher clock frequencies, than
Athlon IIs, they also have twice larger L2 cache, native 128-bit
support for SSE instructions, and slightly faster HyperTransport link.
More expensive Phenom II microprocessors are possibly the best upgrade
option due to their higher clock frequency. Triple- and quad-core
Phenom II parts have lower performance, than Turion II and Phenom II
CPUs, in single- and dual-threaded apps, therefore they are better suited for multi-threaded applications.
