With the Wolfdale core, Intel pours more power into the Pentium package. The 45nm manufacturing tech allows Intel to reduce power requirements to 65W. Lower power means less CPU heat, which translates to lower system heat and longer system life. They also pack more features into the chip.

The L2 cache has been bumped to 2MB and the Front Side Bus has been pushed to 800MHz. They also boosted memory access and execution speed with Wide Dynamic Execution and Smart Memory Access. These technologies work together to let the processor handle more instructions with more data per clock cycle. You'd better watch out -- your enemies will be shooting back faster now!

  • newegg Specialized Dual-core Microarchitecture The Intel Pentium Processor E5800 includes dual execution cores in a single processor to enable execution of parallel threads or applications simultaneously, resulting in revolutionary dual-core performance, breakthrough energy efficiency and exceptional system response time when running multi-threaded applications, or multiple demanding applications. The innovative 45nm fabrication technology optimizes thermal performance for reduced power consumption and noise.
  • newegg Intel Smart Cache Intel Smart Cache Technology dynamically allocates the shared cache to each processor core based on workload. This efficient, multi-core-optimized implementation increases the probability that each core can access data from faster, more efficient cache subsystem resulting in significantly reduced latency for frequently used data and improved performance.
  • newegg Intel 64 Intel 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software. Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.
  • newegg Enhanced Intel SpeedStep Technology (EIST) Enhanced Intel SpeedStep Technology is an advanced means of enabling very high performance while also meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep Technology switches both voltage and frequency in tandem between high and low levels in response to processor load.
  • 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 of the memory where application code can execute and where it cannot. When a malicious worm attempts to insert code into the buffer, the processor disables code execution, preventing damage or worm propagation.
  • newegg Intel Virtualization Technology (Intel VT) Increasing manageability, security, and flexibility in IT environments, virtualization technologies like hardware-assisted Intel Virtualization Technology (Intel VT) combined with software-based virtualization solutions provide maximum system utilization by consolidating multiple environments into a single server or PC. By abstracting the software away from the underlying hardware, a world of new usage models opens up that reduce costs, increase management efficiency, strengthen security, while making your computing infrastructure more resilient in the event of a disaster.

1 out of 5 eggsShould have bought 6-series

Pros: None

Cons: Runs at 1.7, will not clock-up. Intel says tough. Newegg won't RMA MB has FSB of 200, had run a Q9550 on same board at full specs/capacity, so this proc is bad and no recourse. Bye-bye to $80.00 and less purchases from Newegg

Other Thoughts: I wish I had something to say about this experience

5 out of 5 eggsTeh awesomeness.

Pros: Cheap. 45nm so it runs cool. Easily overclockable.

Cons: None.

Other Thoughts: I have this running on an old Gigabyte GA-EG31M-S2 motherboard at 4GHz with a 1333MHz front side bus with a 12 multiplier at STOCK VOLTAGE, prime 95 stable, and never gets over 60C with a stock intel copper core cooler from a Q6600. That's right. Read that sentence again.

Easy way to wake up an old 775 board on the cheap. 4GHz, 1333MHz FSB, 2MB of L2 cache. I'm in love.

4 out of 5 eggsNice for the price.

Pros: Pretty decent price for a fairly fast chip for the old 775 boards.

Cons: The new thin all aluminum Intel heat sinks really are a joke. Stock CPU speed idle temps are 38c. Full load temps with Prime 95 are 65c with the stock cooler. I suppose the cooler is adequate in Intel's eyes for stock settings but any kind of overclock will require an upgraded cooler. Even the old copper core Intel heat sink from the core 2s would be a vast improvement.

Other Thoughts: I upgraded to this from an E2220 Pentium dual core and it is quite a bit snappier. Boot time with Windows 7 is noticeably faster also. I'm taking off one egg for the anemic stock cooler that comes with this CPU and the fact that newegg shipped this in a plastic bag instead of a box so the Intel box for the CPU/fan was pretty beat up. The contents were fine though.

5 out of 5 eggsPerfect Budget OC Chip

Pros: Cheap.
Still on LGA 775. Perfect for those who are still clinging to the 775 standard.
Fast for the price.
Easy to OC.
This chip has a high multi x16, and I was able to get it to 4.0 ghz on air with just 12x multi. It's a good chip.

Cons: More L2 cache would be nice. But so would it being delivered by strippers.

5 out of 5 eggsraise FSB for crunchier chew

Pros: Addendum to my earlier review. Still 100% awesome, I upped FSB from 288 and settled at a stable 361x11.5 multi. 4151ghz

121mhz bump in CPU speed over 288x14 (4.03ghz) but real performance gain. Ripping video from DVD in handbrake went from avg 55 fps to avg 80fps.

Cons: still no cons. stay out of jail.

I just wish I could have got one that needed hardly any voltage to get 4.8ghz+ but I'm pretty cool at 4151ghz 1.38 stable

Other Thoughts: Online forum posts have trended to saying that the e5800 couldn't handle FSB higher than 300, but I have found, along with several other reviews I've read here, that it's fine to hit 333+ and the gain from faster FSB is noticable. Maybe you should bump it up a bit gradually though, and maybe bump the VTT.

5 out of 5 eggsGood CPU

Pros: Intel nails the value CPU market. A fast cpu out of the box, but it's easy to overclock. The high 16x multiplier makes it easy by upping the FSB and a bit of voltage where needed. 2mb cache is fine. This is all the cpu you will need unless you're heavy crunching like gaming, compiling, ripping video, and other intensive tasks. It's still perfectly capable at that, however, for a dual-core with only 2mb cache. Fast and the OS doesn't lag.

Cons: I didn't get 5ghz or a free sandwich or free concert tickets or a pat on the back or good advice or good parenting.

Other Thoughts: I've settled at 4ghz with an FSB of 288 and 14 multi and 1.36v. My cpu is a used fleabay item pulled from an old HP. Your overclocking may be better with a nice new binned CPU.
With an old P35 motherboard and some Kingston Hyper-X and a Kingston 64gb SSD, this is a screaming fast Windows 7 everyday PC.

5 out of 5 eggsfirst build gone pretty successful

Pros: very easy to overclock i have it at 400*9.5 atm..i've only ran prime95 for 10 minutes with max temp hitting 54c idle around 40. matched with my 1600mhz ram 1:1 ratio this thing is actually pretty good, it keeps up with modern games with my 5830.

Cons: Wish it had atleast 3 or 4 mb cache but its alright its still very fast for what i paid.

Other Thoughts: I upgraded from a celeron single core and this is lightening speed to me..i can't imagine myself having an i7-2600k

5 out of 5 eggsGreat Processor

Pros: Great upgrade, very zippy, fantastic value for the price.

Cons: None.

Other Thoughts: Have bought 6 of these in the last couple months to replace some E2140s in Vostro 200 towers for a client and to give new life to a couple of new Socket 755 motherboards I had laying around that I was going to build charity machines for a couple people in need. On the Vostro's is was a night and day difference in speed. Client wont have to buy new machines for at least another 2-3 years now.

5 out of 5 eggsAwesome Processor!

Pros: CHEAP, powerful, low power use 45nm, the last of the Wolfdales! Tons of headroom to overclock. Makes older Socket 775's like the E8400 look very overrated. Compatible with older socket 775 MOBOs with BIOS update.

Cons: None at this price. Maybe some more L2 cache or higher FSB if I had to choose???

Other Thoughts: Using this in a budget build with some parts that were given to me, plus some things I had lying around. MSI P6N SLI Platinum (old), 4GB DDR2800 RAM, Xigmatek Dark Knight Cooler (awesome), EVGA GeForce 460 GTX SE (overclocked to 850 Mhz). Runs cool and fast and uses little power. On this old socket 775 MOBO, which was not known for being a great overclocker, I was able to get 4.2 Ghz stable on Prime 95 on air only. Expect to get a bit more with a few tweaks. If you are bringing an old LGA 775 box back to life, you can't go wrong at $75.
