Reviews Word on the street for the AMD Phenom II X4 965

The six-core chip definitely makes more sense for a video editing rig.

At 4ghz under water, the C3 revision of this chip is a very good performer for the price.

What People Are Saying Give it to me straight

Socket Type

I was able to get this beast up as high as 4.7ghz at one point, but only 4.5ghz would allow me into windows, and only 4.2ghz would allow me to use my system fully with 90% stability.

With the CPU voltage increased to 1.475V in the BIOS, we were able to hit 4.2GHz after raising the multiplier up to x21 from x17.

Until that happens, it's stuck with execution cores that largely date back to 2003.

This processor is based off the same 45nm 'Deneb' core that the previous Phenom II processors and the core itself was made by GLOBALFOUNDARIES at Fab 1 module 1 in Dresden, Germany (formerly AMD Fab 36) using 45nm DSL SOI (silicon-on-insulator) technology.

Processor Performance on Pov-Ray 3.7 Beta 25:The Persistence of Vision Ray-Tracer was developed from DKBTrace 2.12 (written by David K. Buck and Aaron A. Collins) by a bunch of people (called the POV-Team) in their spare time.

I cool it with the stock cooler that came with the FX (it's beefier than the one that came with this one) and I'm running 4.2 gig without overheating it.

The calculations are performed after a spreadsheet with a large dataset is updated with new values and must re-calculate many data points.

This thing can do everything I want and play a game without breaking a sweat.
by The-Overclocker (May, 2012)
This processor outperforms them both in every test and application that I have thrown at it!
by oldcompgeek (Aug, 2012)


The price to performance is light years ahead of intel although I'm smart enough to admit that if you have the money, Intel has the speed... (dang I hate admitting that lol) I would definitely reccommend this to anyone that wants good performance and doesnt need the Intel name.
by oldcompgeek (Aug, 2012)
Overall it is a great chip, I was happy with it's performance.
by Ironman517 (Oct, 2012)
In the first run, the benchmark only uses one CPU (or CPU core), to ascertain a reference value.

The game is a parallel story that follows Sergeant Michael "Psycho" Sykes, a character from the original Crysis, as he faces his own trials and challenges on the other side of the island during the time period of the first game.

Admittedly, the higher clocked 965 does turn the table in the World of Conflict timedemo, proving that more cores often doesn't equate to better gaming performance.
by Tech Radar (Sep, 2010)
This chip was a great buy for the time and it has suited my needs (Folding, Transcoding, Gaming, Non-Hardware Encryption, etc.) very nicely considering that even in March of 2010, it was seriously outgunned by comparably priced Intel chips.

My 965 runs on a M4A89TD Pro mobo at 4.5 Ghz stable all the time. I can take it up to 4.7 Ghz but do not want to stress it that much :) It is water based cooling.
Was a fantastic processor while it lasted... Gaming, video encoding, farming... all very good. Unfortunately is not longer the best option because of the new instructions and IPC.
