What's the difference between Pentium D 915 and Pentium D 920?

[Traveler]

Does anyone know what's the difference between Pentium D 915 and Pentium D 920?

 

[secretanchitman]

both should be $133 or lower.

 

[Traveler]

LOL, quite an answer.

but seriously, what's the difference, in term of spec. and performance?

 

[stevty2889]

920 has VT, 915 doesn't. So unless you are running virtual machine software that can take advantage of VT, there is no disadvantage to not having it. Why would you want a pentium-d anyway, when both X2's, and Core 2 duo's are way way way better?

why are people even thinking about pentium D's ???? Please, I really want to know. The 4300 may be crap compared to a 6300, but the D's are in the toilet...

coz I wanna get something not exceed $100 for my old t775 system, unless c2d drops a lot...

what happened to core duo anyway? seems completely replaced by c2d

Damn you beat me to it.

Um, yeah. In ultra-basic terms it was a nice enough architecture based on lessons learned from the Pentium-M but Core 2 is a complete overhaul and much improved design.

Does 820 also has VT? 915 is thinner and has 2MB cache more. performance about the same?
820 is at least $10 cheaper.
I wonder if I should just get the 820.

They are 1/4th the speed (once both are OC'ed) and take 3-4 times the power and are hot. You really need to save for for a C2D.

8xx series does not have VT, and also runs considerably hotter than the 9xx series. Basicly, there is no reason at all to get an 8xx series, and pentium-d's are the slowest dual cores there are, which is the reason they are so cheap. I had an 830, and it ran at over 75c at stock speeds, on the stock heatsink, and throttled constantly.

Thanks for the advice.
I've been thinking about building a new system with C2D, and leaving the old one to my not-so-use-often family.

Any good suggestions on motherboard, video card and RAM for a C2D system?

The D915 isn't a bad chip at all and has served me very well up until now. 65nm, C1 Stepping, runs fairly cool (by P4 and PD standards). Idle's at about 46C. Under full load, it stays in the mid-50's on stock volts and cooling. My mobo is the limiting factor in my overclock (so don't judge by that). One of the buses (the PCIe i think) isn't locked so i have a few issues when i go higher.

If you want dual core on the cheap, then the D915 is your best bet (for now).

Anyway, I agree with Mark though...Save up and get a C2D (any one...just pick one...lol).

because the 805 can be clocked to 4gHz + on air

 

[batmang]

my d is at a 600mhz overclock and yet a low end c2d destroys it in benchmarks.

 

[Traveler]

it's hopeless to compare a pd with a c2d, it just depends how fast you need it.

BS ! I had one with the best memory, PSA, cooling, etc... 3.5 was the best I could do, and my X2@2.5 blew it out of the water. I calculated it would need to be a minimum of 4.3 top compete with my X2. Nobody on this forum was able to do 4 ghz on an 805.

Now My C2D@3.4 is twice what my X2@2.5 is so that beans you would need at least an 8.6 GHZ PentiumD to compete with my C2D. No comparison.

What toms hardware had was a rare excpetion, most people didn't get close to 4ghz with their 805's, and if you look closely at the benchmarks, a 2.4ghz X2 was still keeping up with or surpasing the 805 even at 4.1ghz..even my old school X2 hits 2.6ghz, with more of the newer ones hitting 2.8ghz, and the core 2 duo hitting 3.2ghz pretty easily, both of which beat the crap out of any pentium-d while running a lot cooler, and using a lot less power..

In a month the E4300 is going to be selling for like 113 bucks. They're not God's answering to OCing like some people believe, but mine is running at 3.4 GHZ right now with fairly cheap RAM and a budget motherboard, and 3 ghz on stock cooling and voltage is not unusual. A 3 GHZ Core 2 Duo processor is going to be keeping you in VERY good shape performance wise for awhile.

Links please? I say "links" because once a lot of average joes can do it then I'll believe it, not just one genius with a voltmeter and extreme air cooling.

I think 3.3 is max to OC a 805

mine was at a 1.1Ghz overclock (3Ghz to 4.1Ghz) and yet got obliterated by an E6300.

and just 2-3 days ago, its starting to overheat and the dumb intel heatsink is so noisy and inefficient...ugh, i hate it. i cant wait to change to an E6600.

I got a 805d and a gigabyte 945d motherboard from newegg 2 weeks ago. On stock voltage I got up to 3.6ghz. A .05v bump to 1.45 got me to 3.7ghz. Thats where Im at now with no issues at all. The weird thing is my temps are freakishly cool. 34 idle and 45 load. I thought it was a faulty temp sensor until I touched the heat pipe at the bottom of my cpu cooler and it was barely above room temerature. the air blowing out is relatively cool as well. The system is prime stable and I have no doubt I could take this chip up to 4 ghz and I probably will when I get bored one day. This is where I stay because Im not comfortable overvolting the chip for 24/7 use

Back to your question,
what's your budget?
If it's low, get a C2D 4300 and a Asus P5B Motherboard. For video, you can probably get away with a 7950GT and check around the forums for a good set of DDR2 800 RAM sticks.
If it's higher, you can probably get a E6300, a DS3P or a P5B board (Maybe even an eVGA 680i LT A1), a 8800GTS, and look around the forums again for the RAM sticks.

And if you get it to 4 Ghz, it will finally outperform a stock X2 3800. No thanks.
