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.

why is it that the speed of my laptops processor was not steady from 795 mhz to 1.49 ghz to 2.09 ghz with p320 amd athlon ii x2

Response: You have Cool'n'Quiter or PowerNow! enabled. This feature saves power by throttling CPU frequency down to 800 MHz when the processor idle. The frequency gets back to normal when you start any CPU intensive task.

AMD Athlon II 2.1 GHz Dual-Core P320

Posted by: Paul S. Doyle

I'm running this dual core CPU in my Compaq Presario CQ62-225NR notebook (typing this on it now), and so far it's been very smooth sailing. I've got 4GB of PC3-10600 DDR3, running Windows 7 Home Premium 64 bit, and the CPU flies through just about everything I throw at it - very real-world stuff.

I've got Eve Online running in the background at 1366x768, eyecandy settings high, and I'm getting around 74 fps. I've got Opera 10.70 running with about 8 tabs, mIRC 7.15 (10 channels), and four Windows 7 sidebar gadgets. I know I can easily fire up IMVU or Second Reality (Phoenix browser) and get decent framerates, no slowdown whatsoever.

This CPU scored 3,106 points on GeekBench 2.1.9 (Ubuntu Linux 10.04, 64 bit), and 1,419 CPU points on PassMark 7.0 benchmarking software (798, total).

Max temp under full load never goes above 51C. I am most impressed & pleased with this AMD P320 CPU.

hiya is just wondering if it is 2.1ghz per core or is that a colective figure??
many thanks
all the best

Response: Each CPU core of the Athlon II P320 runs at 2.1 GHz.

How's it compare?

How does this processor compare to the I3 320m? I'm such an AMD fan, but if I can get more bang for my buck I might have to defect. Been looking at the Intel P6100, T4500, I3 and AMD P320. Same computer specs, same price, just different cpu's so I'm stuck. Any thoughts?

Response: Sorry, we don't have a test system with Core i3-330M. Based on microarchitecture efficiency and CPU features I suspect that the i3-330M will have a noticable lead over then Athlon II P320 in single-threaded, and even more so in multi-threaded applications

Posted by: neil

what is the max temp of this CPU ?

Response: Unfortunately, this information is not published by AMD. Mobile processors may run at higher temperatures than desktop CPUs, so the P320 may get as hot as 70C - 75C under load.

Don't get the core speed

Hi - I have checked with cpu-z and this is definitely my CPU. But it is running at 795MHz, not 2.1GHz...? wtf?
Multiplier = 4 on my system, maybe set lower by manufacturer (HP)?


Response: All mobile processors have PowerNow! feature, that lowers processor frequency to 800 MHz when the CPU is idle. You need to run some CPU intensive task in the background to see processor's real frequency.
