What's the difference...

[carbon8ed]

... between the optron 170 dual core, 2.2GHz, 2 x 1MB cache at £381.82

and the Athlon 64 X2 4400+, dual core, 2,2GHz, 2 x 1MB cache at £281.94

Ignore name, price and box colour - whats the difference in terms of architecture, overclockability, thermal output, voltage input etc?

I'm getting very confused with AMD now. Also are the new AM2 processor 940pin? will they work in SMP mode? and will they run with ordinary DDR?

Thanx

Are you talking about AM2 (different from s940)? The 939 opteron 170 has a stock speed of 2ghz btw.

AM2 processors are not the same as 940 and they have a ddr2 mem controller

The Opty 170 is clocked at 2.0GHz (not 2.2) and is £293.69
The X2 4400+ is 2.2GHz and is £281.94 (OEM)/£323.07 (Retail)

The opteron is designed for servers so it runs cooler, quieter and needs less voltage.
It think the X2 will overclock easily to 2.5/2.6GHz, whereas the Opy should reach 3.0GHz but needing no more voltage than the X2 at this speed.

AM2 is basically a 939 socket which uses DDR2 ONLY. There is hardly any performance gain from AM2 over current 939 systems.

basically the opty is designed for servers, so needs to be more stable...

therefore, theyre the better chips...

thats about it afaik

 

[Gommsta]

whats the point in buying an X2 at all then?

My Bad I meant Opteron 175

Crucial question with the Opty 175 and X2 4400+

Both at 2.2GHz with 2 x 1MB cache but the 4400+ is £100 quid less.

So why buy an opty 175 (it's a 1 series and s939) most servers are dual s940. So server dopesn't seem right - are they failed 2xx or 8xx chips?

Only diff I seen - is better chips - £100 better chips?

because theyre cheaper...

and theres no guarantee the Optys will be better...

They may select the bettter chips, but some of those will go into the standard X2 chips too

IMO - no, theyre not £100 better

Dualcore 939 servers are cheap and perform better than dual-cpu 940 systems.

didnt know you could get dual S939

goes to investigate the Tyan range

Dualcore, not dual socket.

Still 2 cores in both systems, which was my point. Why have an expensive 2-socket setup with registered memory, when you can put in an opteron dual-core into a standard 939 board with regular DDR that performs better for less cost?
