AMD Phenom II Dual-Core N620

2010-12-18 09:16:03
Posted by: Paul Doyle

This is the CPU I want to get, to replace the 2.1 GHz P320 Athlon II in my Compaq CQ62-225NR notebook. The P320 is a fine CPU, and with 4GB of PC3-10600 DDR3, it really flies. But the N620 is a rocket.

It's just that I could always use a little more "oomph" when multitasking, and the N620 is about 38% faster/more powerful than the P320 (double the L2 cache, and 700 MHz faster, for starters), which translates into a real world, system-wide performance increase of about 15 to 20%. Not insignificant. Plus, I can get one for $86 bucks on eBay. W00t.

AMD Phenom II Dual-Core N620 - Upgrade Success!

Posted by: Paul Doyle

Successfully upgraded my HP/Compaq CQ62-225NR notebook CPU - original CPU: P320 Athlon II 2.1 dual core CPU - (25W TDP) to N620 Phenom II 2.8 Dual core CPU (35W). Both configurations with 8 GB PC3-10600 DDR3 RAM (running at only PC3-8500 1066 MHz speed with P320 CPU. Now runs at 1333 MHz with the N620).

Before/after benchmark scores:


Windows 7 64-bit WEI scores with the P320 CPU:


CPU: 5.1

Memory: 7.1 (8GB)

Windows Aero: 4.1

3D Business/Gaming Graphics: 5.2

Disk: 5.9


Win7 Scores with N620 CPU upgrade:


CPU: 6.3

Memory: 7.1 (8GB)

Windows Aero: 4.2

3D Business/Gaming Graphics: 5.3

Disk: 5.9



GeekBench 64 bit score, Win7, P320: 2919

GeekBench 64 bit score, Win7, N620: 3847

GeekBench 32 bit, Ubuntu Linux 10.04, P320: 3124

GeekBench 32 bit, Ubuntu Linux 10.04, N620: 4004

GeekBench 64 bit, Ubuntu Linux 10.04, P320: 3053

GeekBench 64 bit, Ubuntu Linux 10.04, N620: 3898


Everything is about 36% faster, huge performance increase. Runs great.

Benefits of upgrade: N620 runs at 2.8 GHz, P320 only 2.1 GHz. N620's FPU is 128 bit (SSE128), P320's FPU is only 64 bit. My notebook's 8 GB of PC3-10600 RAM now runs at full 1333 MHz speed with the N620 CPU, instead of at the P320's 1066MHz. Also, the N620's HyperTransport link runs at 1800 MHz (3,600 GT/sec); the P320 runs at only 1600 MHz (3,200 GT/sec).
