I run into this blog entry at ZDNet: 4GHz Dual Core Game PC at $825! It is the Pentium D 805 overclocked to 4.1GHZ, which has performance comparable to Athlon 64 X2 4600+ in a lot of tests.
But the author fails to consider the electricity bill when performance/watt is the buzzword today. The sucker consumes 474 watts and needs $300 of electricty per year.
"and needs $300 of electricty per year" is still cheaper than buying a top of the line AM2 peocessor. And after 2 years, a new (faster) processor will be forthcoming again... That's what I call a long term investment.. LOL
ReplyDeletePentium D 805 is surely at a bargain price. But I'm not gonna run something hotter than oven and noisier than vacuum cleaner for hours.
ReplyDelete>>That's what I call a long term investment.. LOL
I really don't think that setup could last that long.
Overclocking like this is cool for a day or so, but reliability, heat and noise tend to dimminish the coolness quite a bit.. Its like driving your car at max revs in second gear ALL the time!. not cool
ReplyDeletewell, the Pentium D will save you some money because you don't have to fire up your radiator or oven, considering how hot it runs...
ReplyDeleteor it will cost you extra, because you will have to run your air conditioning more. Ever sit in a hot computer room in the summer? not fun.
ReplyDeleteit runs at 4600+ speed :) and there is no room for oc in the 4600? i run a x2 3800+ easy at 3000 in stead of 2000, how can a 805 beat that.... with minimal power increase....

I would definitely get a few PD 8xx or PD 920 if it is in the range $50~$100.
ReplyDeletea overclocked pentium d 805 at 4,1ghz has comparable performance of a amd64 4600+?
ReplyDeleteshouldn't the amd processor be renamed to 4100+? *lol*
To be fair, the power usage isn't too bad until about the 3.6GHz mark, and even then a large part of it's probably sucked up by the GeForce 7800GTX. It just goes utterly insane as it approaches the 4GHz mark.
ReplyDeleteWell, it'd suck in the summer. But in the winter, maybe Intel can start a "new" Marketing campaign for their chips that DO IT ALL!
ReplyDelete- Runs like a normal PC
- Viiv in your living room with TIVO like functions
- Replaces your fireplace and warms your house as a space heater with the fire screensaver on your LCD or bigscreen
- Loud blarring fans to drone you to sleep...
- They probably have a lot of stocks in electricity company, so it's a win-win for them either way.
Imagine the possibilities... ;-)
Your evaluation of other websites is very biased to say the least.
ReplyDeleteThe CPU doesn't consume 474 watts, it is more like 244 watts for GPU,
13 watts HD,
2-6 watts ram,
20 watts motherboard,
psu @ 85% efficiency=waste 30 watts
6-10watts= dvd writer
which leaves roughly 170 watts for cpu, now take into consideration the current market price for this cpu- max $100= best bang for buck processor available.
I've noticed your quite quick to judge other sites mistakes but yet you do not see your own!
Read the web-sites carefully before you quote!!!

It's a gaming PC that why you need a 7800GTX
idle @2.66Ghz = 171
idle @4.1Ghz = 259
full load @2.66Ghz = 258
full load @4.1Ghz = 474
... when performance/watt is the buzzword today.
ReplyDeleteI'd agree with you for every other processor segment (server, mobile, corporate PC's, etc), but you'd need a heck of good argument to try and convince me that any person will even concider performance/watt as a requirment for the purchase of a home PC (especially a gamer PC).
And I hate to say this, but just not to be biased I'll say it:
The money saved in NOT buying the FX PC could go against the first 3 years of extra hydro costs. By that time it will be time to buy a new PC (for most anyway).
Heh, i got myself PD805 and Asus P5P800 SE mobo and Zalman S775 cooler adapter for my 7000CU. I spent ~$200. Put my good old DDR1 ram at 2:2:2 timings, and old AGP card (6800GT). Oced it to 3.5G on stock voltage. What i have got - is one heck of upgrade compared to my old S754 Athlon 64. PC is just damn flying with dual core at that speed.
ReplyDeleteNOW what i could buy with $200 from AMD? half of AM2 4200 CPU? Intel is unbeatable when it comes to price/performance with PD 805. If Intel will drop the price of PD 805 to $80 -> AMD is in deep trouble, really deep trouble.

ReplyDeleteThe day I saw those PD 805 at $150, I suggested to AMD that they should produce something like a dual core Sempron. Guess what? AMD has produced an Athlon 64 X2 3600+, targeted to 3rd world market. Apparently, in developed countries, the middle class is not concerned about the difference of a few bucks, so AMD keeps selling X2 3800+ at $300. If you consider the electricity cost and performance differential between PD805 and X2 3800+,X2 3800+ is far better deal. Overclockers are just a tiny % of the users. for instance, I don't like to overclock, it makes me feel every mouse click is potentially unreliable.
Going forward, I suggest AMD to bring the cheap dual core to US market too.
A 2.2GHZ dual core with 256KB L2 can frag the PD 965XE in most benchmarks.
"A 2.2GHZ dual core with 256KB L2 can frag the PD 965XE in most benchmarks."
ReplyDeletePlease post some benchmarks on that one... or a link... or something.
"for instance, I don't like to overclock, it makes me feel every mouse click is potentially unreliable."
I have overclocked all of the computers I have built and none of them have ever failed. Its probably in the approach, slow and steady and find the limits, then turn it down a little.
But please show those benchmarks.
I'm building a new rig with PD 805 plus water cooler for my bro, pushing the bus to 200MHz+ giving me 4GHz+ easily (and giving performance almost on par with top of the line AM2 and better than P4 EEs). Heck, a PD805 + water cooler is still cheaper than a AMD dual core (plus can spend on better GPUs.. LOL). 1 or 2 years along we save the money for another new kick ass rig, hopefully by then some quad core is in sight. Where art thou K8L, or Kentsfield (whatever)?
ReplyDeleteBtw, who cares about the electic bill.. Heck, its not gonna always run 24/7 on full load.. only a few hours when running games.. As long as can play my games to the max, that's satisfaction enough... Dual (or mulit) core is the future!
ReplyDeleteOpteron 165, OC, air cooled, better deal
Some maths: PD805 w/ WC kit = 128 + 89 = 217
ReplyDeleteCheapest price (form NewEgg) for Opteron 165 = 327
Difference of 90 bucks
Hidden cost - high performance RAM needed for overclocking due to higher memory bus frequency
Check this out http://www.techgage.com/review.php?id=5108 another overclocked P-D 820 @3.9ghz vs overclocked A64 3200 @2.7ghz.. (on last page).. Still "hot" stuff though!
