Who decided that FX 53 939 are Clawhammers?

[iCe_bLASt]

I've noticed a lot of people saying that the FX 53 939 are Clawhammers - may I ask where did this info came from ? it is fcloser in a architeture prespective to a FX53 940 from a 3700+ . anyway I decided to send AMD email on this issue:

Message Body:
Is it (fx53 for socket 939) based on a Clawhammer with
dual channel support or a Sledgehammer with non-registered support? I couldnt find this info on your website and except the 1M l2 chache and the open multi is there any other dfference between it to the 3800+?

Hello,

Thank you for contacting AMD's Technical Service Center.

Both processors are based on the Sledgehammer, non-registered memory, but the FX is unlocked, and with 1 MB of L2 cache, vs locked and only half the L2 cache, this makes a huge difference.

Hope this helps. If you have any other questions, please feel free to
contact me.

So it seems like a bit illogical that the 3800+ is a Sledge so Ive decided to send another email , but I didnt save the email so i got only the reply ... so anyway I asked in the second email what is the formal name , and got this answer:

Hello ×?×?× ×ª×?,

Thank you for contacting AMD's Technical Service Center.

Let me first start by saying that the formal name is just Athlon FX-53 939 pin, all the hammer names are just internal code names, and believe me when I tell you this, this is confusing even for us, since there are so many. My previous response means that both processor the Athlon FX-53 939 and the Athlon 64 3800+, they both have the Sledgehammer core, but only the FX is unlocked and has 1 MB or L2 cache. The Athlon 64 3800+ 939, runs at the same speed, but it is locked and it has only 512 K of L2 cache.

Anyway - where did the info about this chip beeing a CH came from ?

P.S.
Notice that this guy name is Jesus ... well I wanted to thank him but since I'm not chrisitan it sounded pretty wierd to say thanks Jesus for the replay... so I just sayed thank you =D

I'm not sure if they're the same chips but if you search Pricewatch, everybody list the FX-53 939's as being Clawhammers

Ha, pretty funny. Actually, Jesus is a fairly common name among Spanish-speaking people. They pronounce it "hey soos", rather than "jee zuz".

[iboomalot]

the 940 pins are Sledge thus SERVER chips

the 754 and 939 are Claw thus Desktop type chips

both are using a "hammer" core

3500+ and 3800+ are Newcastle cores (512kb L2)

This is my understanding of the names/
-----------------------------------------------------------------------------
I guess what I thought was true doesn't hold water going by this screen print.

so its a Sledgehammer with un-reg ram.

[SIOUX]

My FX-53 s939 is Sledgehammer acording to CPU-Z

[iboomalot]

oops i was doing an edit to my thread while you were typing

and my revision A2 Epox motherboard is a revision A1 according to CPU-Z, whats you point?

[Mariachi]

yeah, IIRC the 939 FX's are only recognized as Slegde's, but the true ones are the 940 FX's.

[IvanAndreevich]

CPUZ can be wrong. For example, it's wrong to list all K8's with 512KB L2 as Newcastle. Some of them are Clawhammer with 512KB's turned off.

[OC Detective]

I guess based on the initial reply - what makes a sledgehammer core is dual channel whilst a clawhammer core is single channel.

[EQuito]

My previous response means that both processor the Athlon FX-53 939 and the Athlon 64 3800+, they both have the Sledgehammer core, but only the FX is unlocked and has 1 MB or L2 cache.

They come of articles like:

What's wrong if his name is really Jesus?

[qk4722]

FX-53 S940=Sledgehammer

FX-53 S939=Clawhammer

[iboomalot]

That looks like it should be Sledge = server thus 940 and Claw = desktop 939/754

interesting the name change with a newer version.

[iCe_bLASt]

well CPU-Z is a pretty dumb software if you ask me ...
I doubt that my old C0 3000+ can be a NC .
it also identifys p4EE as NW instead of gallatin/prestonia

whouldnt trust anything it says

[pik-ard v1.1]

older versions detect p4EE's as northwoods, new versions detect them as gallatins.
