I had someone give me a computer with the Pentium D 820 in it the box no longer works but I think the CPU is fine. Is it worth getting a new MB/PS and using it? Not really sure how capable it is / what the best use for it would be. Does it OC well if its worth buying parts for? Or should i just toss it in the spare parts and if i happen to come across a MB then use it? Thoughts and suggestions welcome and appreciated. EDIT: Is it as powerful as my E5200 or is it more Powerful? Thanks Mechh69
These are not too great in my experiance (ive got a system with one somewhere). It has a decent clock speed (2.9GHz i believe) but it runs hot, and therefore reduces the amount of OC potential. I would stick to the e5200, as its a newer litography (smaller nm) and will overclock better with the right parts. Not sure what any1 else thinks but im not keen on the Pentium D 820
The Pentium Ds were amazing overclockers, the 920 (2.66) happily did 3.6 on air and stock voltage, 4.2 on water.
No, as far as I'm aware it's not as good as your e5200 even when clocked higher due to the massive architecture improvements made going to the core architecture over previous. This gives you a rough idea: http://hwbot.org/hardware.compare.do?type=cpu&id=1693_1&id=380_1&id=650_1
The 9xx series where made to a smaller manufacturing process then the 8xx series if memory serves. The 8xx's weren't good at OC'ing at all I believe... Still have my 920 somewhere...
Correct. The 8xx series is based on a 90nm process and are essentially two Prescott cores on the same die. Prescott cores required a lot of power and kicked out a ton of heat, but they were overclockable. The 9xx series was based on the 65nm process and utilized the Cedar Mills cores, which were Prescott cores on a smaller process, essentially. I wish they would have carried on the evolution of the Northwood with die shrinks. They overclocked like no tomorrow.
I'd underclock it and use it as a second system or whatever, provided you can get a motherboard for it for...gah, probably about a tenner to be honest. It's a slow processor nowadays, but that isn't to say that it's completely unusable. As a second system, it'd be comfortably fast enough
The Pentium D is a horrble beast, your e5400 is far superior. As long as you are doing nothing more than simple tasks then the Pentium D can be of use, though I would not invest in any real money to get it up and running
This. My e5200 kicks the crap out of the Pentium 4 we have at work. And thats at stock. You should get 3.3ghz easy out of an E5200.
