With the Wolfdale core Intel pours more power into a Core 2 Duo package. The 45nm process allowed Intel to reduce the power needed to 65W. Lower power means lower CPU heat, which translates to lower system heat and longer system life. They also packed more features into the chip.
L2 cache has been bumped to 6MB and the Front Side Bus has been pushed to 1333MHz. You can now use DDR2 or the hot new DDR3 memory for extreme performance. The processor also boosted memory access and execution speed with the Wide Dynamic Execution and Smart Memory Access. These combine to let the processor compute more instructions with more data per clock cycle. You'd better watch out; your enemies will be shooting back faster now.
Advanced Digital Media Boost has been enhanced with the addition of the SSE4 instruction set and Intel HD Boost. This will give your entertainment experience a boost with better audio and video processing. It will also help with speech recognition, engineering and scientific applications. Perhaps most important of all will be the boost to security with increased encryption power and speed.

45nm voltage
- Pros: After owning the E8400 for quite some time now, I can say to the poster below and to anyone else interested to keep the voltage down. This new 45nm architecture is much more sensitive to higher voltage. Try to keep it 1.4 volts or below. You have a much better chance of burning this thing up very quickly (i.e. a month, even a couple of weeks in some instances) with 1.5 volts than with the 65nm chips. Much smaller architecture means less voltage. You wouldn't put a 5000 watt power amp to huge, high power auditorium speakers if you were using 20 gauge or smaller speaker wire, would you? Very much the same principle inside these 45nm CPU's.
- Cons: See below
- Other Thoughts: Temps will look very good with a "decent" aftermarket cooler. Don't buy watercooling, or spend more than $50 on an aftermarket cooler for these. While those will show much better temps, it's kinda overkill. These chips simply don't produce as much heat as the other (65nm or bigger) architectures will. Heck, a lot of people are overclocking using the stock cooler with great success!!
Best Dual-Core on the market
- Pros: Absolutely amazing chip. This thing will not only run or OC well, but OC's 4.2 Ghz on AIR. Speed and rates as well as load times etc etc etc are painlessly fast and efficient. Recently just built a Quad-Core Q6600 and this just embarassed it. Bravo Intel, bravo.
- Cons: OCing with an MSI P7N Diamond 780i is a bit annoying, but definately doable and stable.
- Other Thoughts: If you're a gamer/enthusiast of OCing your chip, dont even hesitate to buy this proc.

- Pros: It's fast. Just used the included heatsink/fan, which is plenty quiet. idles at 37, gets up to about 68 when encoding video on both cores.
- Cons: I guess the stock cooler could be better. I just didn't feel like tweaking if it was adequate for my usage.
- Other Thoughts: On linux, cpufreq says it supports two speeds: 2834000 and 2000000. In powertop I only see C0 and C1 for C-states. I'm not sure if there's a way to squeeze more energy savings out of it.
Truely amazing
- Pros: I've tried taxing this processor and it keeps shining!
Even with only 2 gigs of memory to work with it's still shining! REALLY runs cool, highest it's got to is 43 deg.
- Cons: Nothing to complain about, this thing is great!
- Pros: Windows index rates it at 6.6
- Cons: None
- Other Thoughts: None.

Highlights
 |
Specialized Dual-core Microarchitecture
The Intel Core 2 Duo processor includes dual execution cores in a single processor to enable execution of parallel threads or applications on separate cores, resulting in revolutionary dual-core performance, breakthrough processor energy efficiency and exceptional system response when running multi-threaded or multiple demanding applications simultaneously. The innovative 45nm dual-core technology optimizes thermal performance for reduced power consumption and noise.
|
 |
Intel Advanced Smart Cache
Intel Advanced Smart Cache Technology dynamically allocates the shared L2 cache to each processor core based on workload. This efficient, multi-core-optimized implementation increases the probability that each core can access data from fast L2 cache, resulting in significantly reduced latency for frequently used data and improved performance.
|
 |
Intel Extended Memory 64 Technology (Intel EM64T)
Intel EM64T provides an enhancement to Intel 32-bit architecture by enabling the desktop processor platform to access larger amounts of memory. With appropriate 64-bit supporting hardware and software, platforms based on an Intel processor supporting Intel EM64T can enable use of extended virtual and physical memory.
|
 |
Enhanced Intel SpeedStep Technology (EIST)
EIST allows the system to dynamically adjust processor voltage and core frequency to decrease average power consumption and average heat production. Combined with existing power saving features, EIST may provide an excellent balance between providing power when you need it and conserving power when you don’t.
|
 |
Execute Disable Bit (EDB)
Intel's Execute Disable Bit function can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas in memory where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.
|
 |
Intel Virtualization Technology (Intel VT)
With Intel VT, one hardware platform functions as multiple "virtual" platforms. For business, Intel VT offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions. In the home, Intel VT allows creating unique user environments for multiple family members using the same platform simultaneously.
