Phenom-II X4-965 BE Features

AMD64 with Direct Connect Architecture

  • Helps improve system performance and efficiency by directly connecting the processors, the memory controller, and the I/O to the CPU.
  • Designed to enable simultaneous 32- and 64-bit computing
  • Integrated Memory Controller
    • Benefits: Increases application performance by dramatically reducing memory latency
    • Scales memory bandwidth and performance to match compute needs
    • HyperTransport Technology provides up to 16.0GB/s peak bandwidth per processor-reducing I/O bottlenecks

AMD Balanced Smart CacheAMD_Phenom_II_X4-965_Deneb_CPU-Z_Stock.png

  • Shared L3 cache (either 6MB or 4MB)
  • 512K L2 cache per core
    • Benefit: Shortened access times to the highly accessed data for better performance.

AMD Wide Floating Point Accelerator

  • 128-bit floating point unit (FPU)
  • High performance (128bit internal data path) floating point unit per core.
    • Benefit: Larger data paths and quicker floating point calculations for better performance.

HyperTransport Technology

  • One 16-bit link at up to 4000MT/s
  • Up to 8.0GB/s HyperTransport I/O bandwidth; Up to 16GB/s in HyperTransport Generation 3.0 mode
  • Up to 37GB/s total delivered processor-to-system bandwidth (HyperTransport bus + memory bus)
    • Benefit: Quick access times to system I/O for better performance.

Integrated DRAM Controller with AMD Memory Optimizer Technology

  • A high-bandwidth, low-latency integrated memory controller
  • Supports PC2-8500 (DDR2-1066); PC2-6400 (DDR2-800), PC2-5300 (DDR2-667), PC2-4200 (DDR2-533) or PC2-3200 (DDR2-400) SDRAM unbuffered DIMMs - AM2+

  • Up to 17.1GB/s memory bandwidth for DDR2 and up to 21GB/s memory bandwidth for DDR3
    • Benefit: Quick access to system memory for better performance.

AMD Virtualization (AMD-V) Technology With Rapid Virtualization Indexing

  • Silicon feature-set enhancements designed to improve the performance, reliability, and security of existing and future virtualization environments by allowing virtualized applications with direct and rapid access to their allocated memory.
    • Benefit: Helps virtualization software to run more securely and efficiently enabling a better experience when dealing with virtual systems

AMD PowerNow! Technology (Cool'n'Quiet Technology)

  • Enhanced power management features which automatically and instantaneously adjusts performance states and features based on processor performance requirements
  • For quieter operation and reduced power requirements
    • Benefit: Enables cooler and quieter platform designs by providing extremely efficient performance and energy usage.

AMD CoolCore Technology

  • Reduces processor energy consumption by turning off unused parts of the processor. For example, the memory controller can turn off the write logic when reading from memory, helping reduce system power.
  • Works automatically without the need for drivers or BIOS enablement.
  • Power can be switched on or off within a single clock cycle, saving energy with no impact to performance.
    • Benefit: Helps users get more efficient performance by dynamically activating or turning off parts of the processor.

Dual Dynamic Power Management

  • Enables more granular power management capabilities to reduce processor energy consumption.
  • Separate power planes for cores and memory controller, for optimum power consumption and performance, creating more opportunities for power savings within the cores and memory controller.
    • Benefit: Helps improve platform efficiency by providing on demand memory performance while still allowing for decreased system power consumption

# DDR2???Rapture 2010-03-10 06:06
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!

# Not reallyOlin Coles 2010-03-10 07:15
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.
