Does anybody use Pentium D 820?

I just wanted to know goods and bads of Pentium D 820 (or any 800 series CPU). I,m going to assmble a system in the near future for a friend.

System would be something similar to the following:

Pentium D 820
ASUS P5LD2 Deluxe
1GB RAM
80GB + 160GB HDD's SATA-2
x300 Radeon 128MB (or something similar)

This system is not for gaming, and won't be overclocked.

Please don't suggest AMD X2's (budget issues). Thanks!
 
I just ordered a similar system. I went with a 6600 video card but otherwise the same spec. I'll let you know my thoughts once its all here. I'm not a gamer either, planning on using it for general computing and some industrial design work (solidworks).

I think the chip is nice, fine and pretty cheap.

However, there are a few factors that make geeks jump on other CPUs:

1) you need a new mainboard, new RAM, PCIe, where AMD dual-core shoppers can reuse a socket 939 board with DDR and AGP

2) while the D 820 is nice and cheap, prices go way up when you want hyperthreading or higher clockspeed. I think geekish people would have liked to see hyperthreading in the base model

3) if you don't spend the major bucks required in 2), then you are getting a 2800 MHz Prescott CPU, and if you don't have multithreaded applications that is pretty slow by today's standard. AMD socket 754 3400+ and 3700+ chips go for $200, 3000+ 939 showed up for $120 or so lately, and these are faster for single-threaded applications

People like me would like a Pentium-D setup because I like the chipsets much better, I can get working full-bandwidth non-PCI gigabit ethernet onboard here, just to name one thing. But for my home server I fear the power consumption of the Prescott and as mentioned I would have to buy everything from scratch.
 
Eshbach from Sharky / XS has the 820. He got it to 5.4, but I guess that doesn't matter to you. He said the CPU is great, even at stock speeds.
 
Eh, I keep computers long enough to just buy a whole new computer. I'm not worried about not having fake SMP (aka hyperthreading) when I'll have the real deal. Granted this is intermediate technology to bridge the gap until an actual engineered solution is available from Intel but props to them for pricing it as the future of desktop computing and not taking AMDs elitist super computing pricing.
I wont make any claims that this is superior to the AMD when it clearly is not but at half the price, I dont care! I'm not a gamer and not that concerned about raw power. I think this is the way to go for mid level computing.

""not having fake SMP (aka hyperthreading) when I'll have the real deal.""

Statements like that will limit the replies you get. Only some user who'd never touched, seen or used a P4 would say something that uninformed. Not many folks see Hyperthreading as real SMP. At its best it performs like 1.4 or 1.5 processors in mulitthreaded apps or multitasking, one and a half is not two or fake SMP. Even two full processors don't gain 100% from having two processors as compared to one.
So, read more 2CPU.com and less Anandtech and the AMDzone. ;)

The Pentium D doesn't need Hyperthreading because then you'd need apps and an Operating system built to take advantage of 4 threads, this is rare.

If you don't game, use the Pentium 820 for Multithreaded apps, then it hands any AMD processor near its price range like the 3500+ its ASS! I don't know what that other guy was talking about. Single Threaded Apps are one thing but all computers are tools and you should use the right tool for the Job=P The very first review showed the costs-more than-the-PD 820 3500+ getting spanked in multithreaded apps and multitasking. Then if you're not using it for those tasks, then go with AMD or whatever single processor you like.

I'll stand behind my earlier post and ignore your comments regarding my past computing experiences. I never claimed hyperthreading was real SMP. I never claimed there was a 100% gain from either hyperthreading or true dual cores. The facts are that hyperthreading is an attempt to execute threads in parallel but it certainly has its limitations compared to true dual processors or dual cores. Given the choice between dual cores or hyperthreading, I chose dual cores and bought the 820.

I stand behind what I said as well. I didn't phrase it as a Flame or a put down, just a point. Anyone who has used Hyperthreading knows it has it strong and weak points. Many more positives than negatives in most cases though. Given the choice, I agree with you and would take an 820 as well, surprised? NOTHING is absolute and you buy the tools to fit your job. All jobs or not the same.

I copied and pasted your comment about "Fake SMP" and made my comments based on that and said as much. The "facts" as you say is just this, Hyperthreading can cause anywhere from a -9% hit to a 30% gain. If anyone only wants to point out the good or the bad, they have a problem. That's where flame wars start. I said the 8xx don't need Hyperthreading. I'll add that it is a very GOOD feature on single Processors.

That was exactly my point, so I wasnt quite sure why you're calling me out on this.

I didn't intend to call you out. I just didn't think your comment about "Fake SMP" was right, that's all. If I'm wrong here for the way I said it, hey, MY BAD! I agree with you more than I disagree.

Hyperthreading on Dual cores = up to 25% improvement over just Dual cores.

The P4 benifits from Hyperthreading even when you have dual cores.

True given the choise, Dual core is better than HT, but DC with HT is even better.
