Intel Core 2 Duo E7400 Wolfdale Dual-Core 2.8GHz LGA 775 65W Desktop Processor BX80571E7400

  • 1066MHz FSB
  • 45nm Wolfdale 65W
  • 3MB L2 Cache
ICON Loading...

With the Wolfdale core, Intel pours more power into a Core 2 Duo package. The 45nm process allowed Intel to reduce the power needed down 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 3MB and the Front Side Bus has been pushed to 1066MHz. You can now use both DDR2 and the hot new DDR3 memory for extreme performance. They 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.

The Advanced Digital Media Boost feature 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.

  • newegg 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.
  • newegg 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.
  • newegg Intel Extended Memory 64 Technology (Intel EM64T) Intel EM64T provides an enhancement to Intel 32-bit architecture by enabling the mobile 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.
  • newegg 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.
  • newegg 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.

5 out of 5 eggsJust what the doctor ordered

Pros: Reasonably priced
Easy to OC
Power stepping
Did what I needed it to.
Been in service since 2008 overclocked to 3.4 GHZ with stock heat sink

Cons: Two cores

Other Thoughts: E7400
G43-Twins Full HD
Nvidia GTX 550 Ti
4 GB Crucial memory 400 mhz
Windows 7

I am thinking about replacing this processor with a Q9550 to hold me over for another year or so. I would like to be able to play some of the newer games out optimized for multiple cores. This processor has however proven to be reliable. It was with me through my last two years of high school and two years of college. Playing the Fallout series Crysis Bioshock Metro 2033 and a few other games. Maybe I will use the remains of this computer for a home entertainment system or something... Who knows! But I think anyone will agree this was a fine product and a HUGE step up from the Pentium 4 or the Pentium D.

4 out of 5 eggsWolfdale!

Pros: Used this little guy in a budget build back in 2009. He's done his job admirably.

Cons: Even back when I bought this guy there were better, more expensive, options. I could have sprung a little more and got more core, but I didn't feel like waiting for another payday.

Other Thoughts: Still a nice little worker -never given me any major concerns.

5 out of 5 eggsVary Good

Pros: I run this at about 3.2Ghz and I have only had one thing go wrong and that was a power thing. I play online games and run a OC VC and CPU and leave my ram alone and my old OC Power supply went out under the pull but the CPU is still kicking. Id never go with any one other than Intel and Newegg.com is the place to get it.

Cons: NONE

5 out of 5 eggsGreat Chip

Pros: Fast

Cons: for what it is, none

Other Thoughts: Had for a year now, just decided to upgrade my cooling and overclock it to get some more performance. Have it running at 3.5 ghz stable, no sweat, could have gone with more but my northbridge on my horrible p31 board was getting too hot. Probably wouldn't purchase this right now thought, since you can get into an I3 setup for the same CPU cost and 775 is dead. But if you are looking at this chip to drop into an older board, this chip at the right price would be the way to go.

5 out of 5 eggsWHOOOSH! FAST!

Pros: - Works fast, easily overclockable, works like a king.

- This makes look most i3's look obsolete.

- Even without virtualization tech it's great.

- Overclocked to 3.5 GHZ without a problem, very stable.

Cons: - Not the best processing in the world, when I produce after I put around 20-25 vst's in one project it starts to take a heavy load.

Other Thoughts: - I'll miss this when I upgrade to a Quad Core.

5 out of 5 eggsGreat!

Pros: Working great. I have no need to overclock it, and running at the stock 2.8 I've had no problems.

Cons: I can't fit my hand in the Pringles container. They should make the cans bigger.
