Closer Look: Phenom-II X4-965 BE

The latest series of processor from AMD offer a large 1.47 x 1.47" (37.31 x 37.31mm) integrated heat-spreader surface, which helps dissipate all 125W maximum TDP that the Phenom-II X4-965BE CPU is capable of producing. Compared to Intel's latest Core i5 series, as well as the older Core 2 Duo/Quad processors which measure 28.5 x 28.5mm, the Phenom-II AM3 processor offers 71% more contact surface area. If you compare the latest Intel Core i7 processors which measure 32 x 35mm, then the Phenom-II series still offers 24% more contact surface area. For overclockers, this means a much larger area to cool, but also much more manageable core temperatures.


The AMD Phenom-II X4-965 Black Edition processor (HDZ965FBK4DGM) is specified as having a 0.825-1.4V nominal voltage, and uses the 45nm (.045-micron) DSL Silicon on Insulator (SOI) process technology construction. AMD's 125W X4-965 is a socket AM3 938-pin organic micro pin grid array (micro-PGA) processor by design, with backwards compatibility to the AMD2+ socket. There's also "Heavy" load support for DDR3-1333, and with proper BIOS implementation the memory controller will now support up to 4x DDR3 DIMMs at 1333MHz.


The Phenom-II X4-965 BE processor offers a total cache of 8.5MB, split into three levels. The L1 cache delivers 64K of L1 instruction and 64K of L1 data cache per core (512KB total L1 per processor), while the L2 cache offers 512KB of data cache per core (2MB total L2 per processor). The final level 3 (L3) cache shares 6MB among the four processor cores.


Based on the updated 125W TDP architecture, increased cache size, and a larger IHS footprint, this 'Black Edition' Phenom-II may be exactly what hardware enthusiasts and overclockers need during an economic recession. In the following sections, Benchmark Reviews tests the 125W Phenom-II X4-965 directly against the Intel Core i5-750 to illustrate value, while also comparing performance against the original 140W AMD Phenom-II X4-965 BE. While benchmarks help separate the products, real-world experience and gaming frame rates paired with affordable product pricing will ultimately decide which CPU is really 'better'.

Why would you test AMD's flagship processor with DDR2 memory??? You're practically giving Intel's i5 processor the edge in all the benchmarks!

Since the DDR2 we tested was the same speed as the DDR3 there wouldn't be any noticeable difference, let alone a measurable one. I suggest that you read our "DDR3 RAM: System Memory Technology Explained" article located at

Even if they both used the exact same memory kit for each system, the Intel i5 would still have the advantage of an integrated multimedia controller directly on the CPU.

Care to Re-Run those Benchmarks with the i5 @ 4ghz and Amd 965 both at 4ghz? Clock for Clock AMD does less ,it's Just the Way it is ...Amd is for Budget gamers and intel is for Enthusiasts (with money),Simple...(I'm not a "Fan Boy" ) I've bought Both...

the phenom 2 has a memory controller directly on the cpu. didnt you know this?

Yes, I know this... it's in all of our reviews. Did you mean the the integrated multimedia controller? That's what I had referred to.

# overclocking to 4.0mark 2010-06-12 09:06
i have the same CPU as you do. i have a h50 CPU cooler, 2X2gb g-skill of ram, 1tb caviar black and ASUS M4A78T-E motherboard. i've been looking for the right settings to put in my bios, but never succeeded. whenever i would run a stress test it would crash after a few seconds. usually in order for it to be stable, the test has to run for an hour or 2. mind helping me out?

# What are your settings?Olin Coles 2010-06-12 09:42
You really didn't give us any usable information, such as voltage and BIOS settings.

woops, my bad. voltage: 1.5 - bus: 200 - multiplier: 20 and the rest is set to Auto.
