Cost of ownership. A casual user can easily burn up $3/month in electricity over what they'd burn using an X2 3800+, a Sempron, or a Yonah. In fact, the difference is probably closer to $4/month vs a Sempron or Yonah. A hardcore overclocker running an 805 24/7 can burn up a lot more than that($10-$15/month extra per month).

Unless you leave your PC turned off frequently AND upgrade frequently, that 805 is going to burn a hole in your wallet. It is not a bargain for people looking to squeeze all the performance out of their CPU on a regular basis.

Budget CPUs used to be cheaper across the board than more expensive, more powerful CPUs in that one could easily assume that they used less power than more expensive CPUs. With the 805, that is no longer true.

Why people claim the 805 is "cheap", I don't know. Do you not pay for your electricity?

And unless you live in the artic, or don;t have AC, then the extra power required to heat the pig, and if you OC, the extra money for the bigger heatsink and PSU required, etc....I already posted that and got flamed.

Does anyone know the power usage on the 805? Based on temps that I have personally seen (32C idle, 45C load with stock heatsink) I think power consumption may be lower.

Appears to still be 95W...

Would that be idle or load? Seems like that could be idle... I wish AT would take a look at this little processor and give us the low down on power consumption and motherboard compatibility...

why do people still care about PentiumDs??? Great products are coming in Q3 of this year from Intel, and people still want a Prescott/CederMill/Smithfield/Presler? Athlon64 and X2 are simply superior, and Conroe/Merom is right around the corner.

:roll:


Find me one AMD processor under $200 that can outperform an FX57 in multitasking.

Conroe and Merom are not out yet, thus we cannot purchase them.

Yikes...sorry, didn't mean to open a can of worms, I was just curious how they compared. Like I said, I'm really happy with my 3.4C and really have no need to upgrade, but if I'm buying a new motherboard I'd rather get something that's a little more future-minded, and that basically means getting a new CPU. Honestly, I don't see myself gaming on my PC anytime soon (the 360 gets all of my time), so I might go with something like the 805 or 820.

 

[openwheelformula1]

keep in mind that currently no motherboard out there can support Conroe. "Maybe" Asus's 975 based board which costs more than the processor, but it's still doubtful. Keep your Northwood and wait til 965 chipsets come out.

Never heard of Conroe...is that the next dual core series?

My Pent D 805 oc'd to 3.44GHz runs on the stock retail heatsink+fan, with the 350W power supply that came in my $30 Antec case...

What are your load and idle temps?

Uuu. Nice

Just curious, what do you guys pay for power? In Seattle, we pay 8.39¢ per kWh, over the initial 10 kWh per day.

Also, how much power do you think both procs take? Can we compare a oc'd X2 3800 to an X2 4800 and an oc'd Pent D 805 to a Pent D 840? If so looks like the Pent D 840 is ~90 watts more than an X2 4800.

http://techreport.com/reviews/2005q3/athlon64-x2-3800/index.x?pg=13

So it cost ~$5.50 more a month to run a Pent D 840 than an X2 4800, at full load.

First, Antec doesn;t have any $30 cases $49 is the cheapest. Second, at what vcore are you running, and at what full load temp ? What video card ? what drives ? Based on mine, I find it hard to believe you could be stable at that speed without raising vcore, and then the PSU would not be enough. Mine won;t run even with a 450 watt Fortron psu if I add a good video card.

 

[ronnystrauss]

get an opteron 165 for 325 then get the arctic freezer 64 pro for 35 and overclocked it to 2.6ghz its beastly

It was a Frys special, Antec SLK1650. $59 - $30 MIR, you can probably find the deal in the forums.

Stock vcore. 57'C load temp, two instances of Prime95. EVGA 6600GT. Maxtor 160GB 5400rpm drive. Asus P5SD2-X motherboard. Prime95's been running for ~24 hours.

Maybe I got a good one, but then if people are running these at 3.7GHz, my 3.44GHz 172fsb doesn't seem so unrealistic.

well atleast you are getting your bang for your buck ::thumbsup::

That's all my point was. I like my X2 3800 a lot, it was cheap, takes little power, runs on a so so motherboard, and at near 4800+ speeds (2.4GHz).

But I needed an HTPC box and on a budget, I don't think the Pent D 805 is that bad of a choice.

It's going to come out higher than that for most 805 overclocks, since few people stop at 3.2 ghz(which is a lousy OC for the 805). Secondly, the 4800+ will actually use slightly more power than a 3800+ OCed to 2.4 ghz at stock vcore due to the extra l2 cache on the 4800+.

I'll quote Acanthas as saying that a stock 805 will cost you an average of $3 extra per month in power costs over a stock 3800+ at statistially average usage levels, with overclocked 805s costing potentially quite a bit more depending on vcore adjustments and final clock speed. If you're like most budget shoppers and you hold on to your rig for years at a time, that extra $3 per month adds up. Each year is an effective $36 extra you paid to use a "budget" CPU. Given my current usage patterns, the 805 would cost me $144 extra in power bills to own compared to a stock 3800+, and that's not even taking into account the cost/month if I kept my machine at load 24/7! It would be worse then.

I see no sense in splitting hairs over the 805. If you're going to own it for a short period of time, okay, fine. It might make some sense if you can stomach owning a Smithfield(I can't). Getting a low-end desktop Yonah would top my "to do" list within the next 3-6 months were I interested in a budget dual-core system before Conroe comes out. As much as I like the X2, the Yonah is pretty slick, and it uses even less power than the X2. A ~$300-$350 Yonah would be perfect.

Um what? With this

http://www.newegg.com/Product/Product.a...1180&CMP=OTC-pr1c3watch&ATT=19-111-180

on the market, why would you even think about an 805, especially for an HTPC?

Yonah > Smithfield

 

[croak]

Some of us have to make our immediate dollars stretch farther and can't buy $250 Yonahs

But come on, the whole point here is how does a Pent D (805) compare. It takes more power, and overclocking is never guarenteed. But it's cheap and isn't that bad of a performer.

not trying to argue (although on a forum it's hard not to come across that way) but the arguments about costing more per month to run a 'budget' system are streching it quite a bit. Sure, $36 a year would be the added cost of the budget dual-core, but come on, at this rate, it would take nearly 3 years just to reach the price point of the next dual-core system. To me, that pretty much comes out in the wash.

Like you said, no use in splitting hairs on the matter, but I think it's ridiculous to think that some are basing their upgrade path on the power consumption. If that were the case, there are much better ways to lower the power bill. Get a low power microwave, fridge, etc. Most of the folks on here griping about the extra power usage probably aren't even paying the power bill anyways.

I figure it comes down to justifying paying 100% more for 10% more performance.

You also forget about the extra power required to COOL the house in the summer months, and the irritation of a hotter PC, and the extra heat can damage other components in the PC. Not to mention, you still have a slower PC. And for a good OC, you need a bigger heatsink than a 3800 X2 requires. Nobody yet has been able to refute any of this, other than they just call me a fanboy, or say they can;t afford a 3800. The extra power required and the the $$$ refutes that argument also.

 

[NaOH]

I don't really have any experience with the Pent. D. But doing some research, I have found nothing good about them besides the fact that they are cheap. I don't think that is a good enough reason to upgrade to it unless you are really on a budget and can't help but fall for the dual core craze. Shoot 400Mhz overclock on my 3800 x2 using stock everything (besides AS5) and running like a champ. I don't doubt that I will be able to go higher. Once I get the STOCK AMD HSF with heatpipes, I'll be good to go up to 2.6 or 2.7.
