Main difference between fx55 and fx 57?

Madwelsh · 10 Apr 2006 at 16:55

Hi there, aside from the 120nm process and 200mhz, is there essentially any difference between these two processors? I run a vapols, would they clock the same? If you were running a vapo and could get an fx55 for 150 less than an fx 57 what would you do?

The $64,000 question.

I don't know enough to comment about the architectural differences between FX55 and FX57, but as far as I know the only difference between them is the 200Mhz clock speed and the 120nm process as you mention.

It is likely therefore that FX55s are speed binned FX57s, so I would guess that you wouldn't quite achieve the same overclock (assuming exactly the same cooling and other hardware) on an FX55 as you would a FX57... maybe 200Mhz less?

The FX55 comes in both 90nm (San Diego) and 130nm (Clawhammer) cores.

If they're both 90nm then there is no difference aside from the stock speed, though the 57s obviously tend to clock slightly better.

I have the FX57 great CPU

I went and bought an FX55 in the clearance section, it is a 130nm (Clawhammer) core. If only i had asked if there were more than one type. I presumed that FX55's were all 90nm with sse3 !!!

By the way what voltage should this thing be running on ?

Kesnel · 29 Apr 2006 at 12:15

1.5v at stock.

Out of interest, how much did you pay for it on clearence?

deadeyedic30 · 29 Apr 2006 at 12:19

Including P&P £360. Flipping impulse buys. Could have cancelled the order as Ocuk had trouble finding it in their stockroom.
CPUZ reports the volts as 1.6
Probably should have changed order for a X2 4400 :rolleyes:

What do you reckon, should i see about returning it and getting the X2 4400 ?

I'd see if you could return it, thats a whole lot of money for not a very impressive chip, most £100 Opteron 144s will out clock it.

and run a lot cooler and consume less power.

get it sent back if you can

I agree. It's just not worth having an FX chip (except FX60, but it costs twice as much as an X2) nowadays with the advent of dual cores imo.

You'd only start to see the benefits of an FX chip on phase-change cooling I think (when you actually care about changing the multipliers, etc), and even then you have to dodge the coldbug minefield!

I recently sold on my Clawhammer FX55

Best thing i ever did.

The heat these things churned out was to much for me , and as a comparison:

FX55 @ 2.6 = 59 load

X2 4400 @ 2.6 = 39 Load

The 90nm rather than the 130nm of the clawhammer means it will run cooler but once you have a second core in there the temps shoot up. Im guessing you must be running the volts very differently

Coolasmoo · 30 Apr 2006 at 14:16

Yep,

The FX was at 1.5v and the X2 is at 1.35v

I'm stuck with it as i have used it. Talk about feeling well robbed. If i had known i was ordering a Clawhammer i wouldn't have bothered. Oh well, a competitor do better delivery rates to Northern Ireland for all future pc upgrades. :mad:

Can't you pay a restocking fee to return it?

deadeyedic30 · 1 May 2006 at 18:28

Asked but they said no, because it has been opened and used. All thats been used is the cpu nothing else such as the stock cooler or the case badge. Only thing i did to the box to open it was cut one of the AMD stickers they use to seal it.

I hear the auction site calling...

deadeyedic30 · 1 May 2006 at 18:57

Its a possibility, but what fool would pay near to what i did for it ? I wouldn't, not for the clawhammer. Whole point of ordering it was because i thought i was getting a newer cpu than what i had, a Winnie 3500.

You'll still get a good price for it, definately worth a shot, people just see FX-55 and impulse buy on there.
