|Clock Speed:||2.8 GHz||UPC:||
|The Intel 820 2.8 GHz CPU works great for a single PC on a high-speed Internet connection. This Intel Pentium D processor contains a dual core, meaning that it has two cores and two threads. It also includes both L1 and L2 cached memory. The L1 cached memory capacity is 32 KB, while the L2 cached memory capacity is 2 MB. An addition to the memory specifications is a 32-bit physical address extension. This processor runs optimally at a temperature of 147.4 degrees F and below, and it supports the PLGA775 socket type. The voltage range for this 2.8 GHz CPU is 1.2 volts to 1.4 volts, allowing for energy conservation. In addition, the Intel 820 features a bus/core ratio of 14, which is followed up by a maximum FSB speed of 800 MHz. The maximum manufacturing process is set at a rate of 90 nm with the maximum TDP being 95 watts. Additional enhanced features on this Intel Pentium D processor include Intel 64, Idle States, and Execute Disable Bit.|

Cheap as dirt. Rock solid and dependable. Still a modern compettitor.
If you're looking for cutting edge speed and performance, you may want to check out something like the I7 class. If you're looking for a hardwarking, cost effective, easily built, still competitive tower for not a lot of money? This may be your cpu. Socket 775 motherboards as of this writing are relatively cheap. Ranging from 25-125 for bargin basement simple boards. The Pentium D 820 makes up in compatibility, what it lacks is speed. It's steady and reliable. Average cost at this time is around 10-20 usd. For those just needing a web surfing machine or light gaming while keeping it within a small budget, this will likely fit the bill. It clocks 2.8ghz (effective 5.6ghz vrs single cores) leaving it on par with many of the cheaper 500usd area laptops and budget desktops. It's 800fsb is still pretty standard for computers used today unless you're willing to spend around 1000usd or better. It's only narrow drawback is an on board cache size of 2mb vrs the 4mb of similar Pentium D's. Though it seems to be a bit more compatible than it's 4mb counterparts as well. This is attributed to it lacking one of the features they do. A comparison of the 820,830, and 840 will reveal what.
CPU upgrade for an aging Dell Dimension computer that works!
I bought the processor to upgrade the cpu in a Dell desktop that was getting a bit long in the tooth (Dimension e510) The PC came with a 3.2G Pentium4 HT. I had done some reading about the capability of the motherboard, and by the specifications it appeared that it would support the better dual core processor, although it is not listed as a possible upgrade. Fair warning: the bios complains about an incompatible processor at boot time, but properly recognizes and identifies it. The upgrade has increased the performance of the machine. I am surprised, a bit, that it works as well as it does. At this point, I am wondering if I could get a faster Pentium D cpu (think I can), but I am uncertain if there may be some voltage limitations on getting to the fastest Pentium D CPU. As this upgrade is not listed by Dell as possible (maybe due to he bios restriction?), I am quite pleased with the purchase. The item works very well, was a good deal and has accomplished my objective to upgrade the CPU in this old machine. All good.
Works good fo a pricebuster chip
The Smithfield core is essentially two Prescott cores stuck together on a single chip. No other major architectural differences exist, except that the Pentium D line does not have HyperThreading on it. Unlike the Extreme Edition 800 series which can have a total of four logical cores (two physical cores with two logical, HyperThreading cores each) the Pentium D is strictly two single threaded cores. The advantages of having a true dual core processor over a single core, HyperThreading processor are fairly noticeable and users should see a good sized increase in performance going from a HyperThreaded CPU to a dual core CPU in benchmarks and applications that take advantage of multiple processing threads. We'll see this illustrated in several of the coming benchmarks.
Works like a dream
I upgraded my Intel Celeron 2.4ghz processor with the Pentium D 2.8ghz hoping to get a small boost in speed out of my Linux/MythTV setup. The speed difference was far more significant than I thought it would be due to the fact that the Pentium D has 2 processors in it. I haven't had time to experiment with pushing the server beyond what the Celeron was doing, but the server huffs and puffs A LOT less than it used to. I imagine it could serve up TV with real-time commercial flagging and transcode a program at the same time with ease- something the Celeron would stumble on.
A fast processor
My brother needed his computer repaired. I picked up the Dell Desktop and brought it to my computer shop to diagnose it. The computer would not boot to windows. I had to remove a bad memory module and install a new hard drive. That fixed the problem. I then decided I would surprise my brother with a little something extra. I searched to find out if the motherboard would support a faster processor and what processor would work for this purpose. I decided on the Intel Pentium D 820 - 2.8 GHz Dual-Core (HH80551PG0722MN) Processor. I installed it and returned the computer to my brother. A week later he called about some problems finding software he wanted to install to use for his band. He then told me, he did not know what I did to his computer, but it was faster then it had ever been and when I told him about the processor, he told me I could never have made a better choice.
