3.7 Ghz here: HKEPC

btw, looks like $150 is about the normal prices for these newly released 805s according to froogle

Any opinions on this proc. I'm looking to jump soon on a dual core something. I hear although some of these intels are not as fast as the amds they can be good for the price. I don't need anything too hot. My current amd athalon 2600+ is still doing well except when I get too many things going at once.

Sounds like the best 150 bucks you can spend on a cpu... especially with smp benchmarks of
quake 4 that were released eariler.

couldnt one just lower the multi and boost the fsb to 800 seeing as every recent board out there should be able to do that? or are intel processors locked up and down?

looking for a cheap dual folding box to play with.

I think intel isnt even really sure about these cpus, from there footnote on the 805

"15.This processor uses a physical signaling scheme of quad pumping the data transfers over a 166-MHz clocked system bus and a buffering scheme allowing for sustained 533-MHz data transfers."

I think that would be 533/4=133mhz

Darn.. this boy is so tempting me. I know Smithfield sux, but who cares, it's $ 150. I slowly think I should say good bye to my X2 3800+..

i was thinking, if there was a dual proc board for this baby, 2 of these would make an awesome quad core server rig

yea it is 133Mhz.

The performance problem is 2 cpus fighting for bandwidth over the 133bus. The other P-D's get 200mhz to share. So even at 3.32ghz (166mhz bus) it performs closer to a 3.2Ghz (200bus) as you do lose some with the weaker FSB.


But seeing as this is a B0 steeping, I guess there is no plans for a 905 :(

Very tempting. I've wanted to go dual core but the AMD offerings are out of my price range. Any recommended boards to go with this proc?

Depends what you want to do. Boards that support dual core P4 can be had for under $60 and then after that go up to and over $200.

The Asus P5LD2 is fairly inexpensive for a board that supports dual core procs (945P chipset).

I just ordered one for a client build yesterday along with the Foxconn 945P board. I'll chime back in too :)

*From here on out, it is only dual core 64 bit machines for clients who want to buy new PC's. I love technology!

No Dual core D chips do, only the EE (Extreme Edition) does and it has been shown to actually slow things down in some games and other apps.

That and Dual Core > Single core with HT

These are (literally) hot if you don't mind paying for a very good heatsink, a good o/cing motherboard, and don't pay for electricity.

These 805's are the newwer B0 stepping. They run cooler then the A0 ones. Mind you yes the factory heatsink shoul be good for up to 3.3-3.4ghz range depending on case and outside temps.
