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.

Great CPU

Reviewed By: David on 1/26/2009

Tech Level: high - Ownership: 1 month to 1 year

This user purchased this item from Newegg

Pros: Took some work to get it stable for gaming but currently running at 4.1GHz (1.36v 24/7) with an Arctic Cooling Freezer 7 Pro and idling at 33*C. Max under non-synthetic usage is appx 56*C. Huge performance increase from Pentium D 820 ( OCd to 3.8Ghz 24/7 ). As the CPU had previously been a bottleneck Far Cry 2 went from 25-30 FPS with random hangups to 45-50 with no lag ever.

Cons: ended up using a 10x multiplier with a slightly higher bus speed so in theory could have gotten the e7300 assuming i got the newer stepping guaranteed in the e7400.

Other Thoughts: 4.25GHz

E7400

Reviewed By: tCup on 1/20/2009

Tech Level: somewhat high - Ownership: 1 week to 1 month

This user purchased this item from Newegg

Pros: This processor is really nice for the price, you cant beat it. I run this overclocked steady at 3.15GHz and have not had any problems.

Cons: None

Other Thoughts: If you are replacing an old E6300 or one of the older chips made by intel use the older heat sink and fan, its bigger and will give you smaller temps, good luck.

works great & oc's nicely as well

Reviewed By: Luke on 2/2/2010

Tech Level: average - Ownership: 1 week to 1 month

This user purchased this item from Newegg

Pros: was amazed at how easy it was to OC this. I pushed it from 2.8 to 2.94 with very little effort. believe it or not the stock HS & Fan work just fine.
Its low profile design so it has ample room in a smaller case.

Cons: be careful with the CPU Fan it comes with, the fan wire was wrapped around it and I heard a horrid clicking till I realize the fan wire was being clipped by the Fan. ha ha ha. could of been harsh if the fan cut the wire.

Other Thoughts: i got some extra silver thermal grease just in case. the oversized OCZ cooler I bought was too big for the case! lol the Stock HS/Fan worked fine for my case. Can't believe how small these LGA 775 processors are...

Awesome CPU!

Tech Level: somewhat high - Ownership: 1 week to 1 month

This user purchased this item from Newegg

Pros: Fast and sleek. Very nice CPU. I am very pleased with it.

Cons: If i could give it four and a half stars i would. The only problem is the junk heatsink attachments. But other than that everything worked out fine!

Other Thoughts: BUY ARCTIC SILVER!! This was my first build and i had no idea of arctic silver. So, I didn't buy it. With the lack of arctic silver, I had to under-clock my CPU to 1.5 G Hz just to keep the thing form melting! I basically can't run my machine now until i get some of the stuff. Rookie mistake, I know, but I think that the heatsink has something to do with it as well. Might want to look into a aftermarket heatsink, just for the heck of it.

Introduction

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 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.
	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.
