well i consider a hammer core with 512kb of L2 cache disabled to be a newcastle, usually. just wondering what your sources are.
because, from my understanding, all the cores are made the same, but they just disable stuff (cache, lock multi's) for different lines of chips, so i dont see how a clawhammer with ½ cache disables is anything but a newcastle. (a rose by any other name type deal)
m0nk33y, a clawhammer has 2x the l2 cache, which sets it about as ahead as 200mhz extra would.
That's fine if you want to look at it like that, but simply saying there were never 512kb clawhammers is an inaccurate statement. I think the whole thing with newcastles was to add an extra 200mhz to compensate for the lack of L2 cache. The cutdown claws were just cut down and never had the 200mhz to even it out with the exception of the 2800+ and 3000+newcastles. Also you should know that newcastles are all CG steppings (better mem controller) The cut down clawhammers are are all old CO stepping.Quote:

When they say stopped production of 754 do you just mean the Clawhammers or the Newcastles as well - surely not!?Quote:

I called AMD today and they said the Mobile AMD64 90nm Oakville cores will be for socket 754. Also they told me the amd64 754 for desktops will stop or have already stopped production. 754 will be for semprons and existing amd64 754 cpus. The lev. 1 cache amd 64's have been phased out except for FX line. I couldn't get a straight answer when I asked if the FX55 will be 130nm or 90nm. My guess is 130nm and then switch again to 90nm. Eventually all amd processors will be 90nm including Semprons. I guess, if you have a 754 board that supports mobiles, but you want a 90nm processor without getting 939 mobo, then the Oakville is the answer.
Both. The only processors in production for 754 are semprons and mobile amd64's.(oakville)Quote:

Winchester will replace the newcastles for 939. And San Diego will replace the clawhammer FX 939.
Regarding the disabled clawhammers being Newcastles - this is incorrect. The core size of a Newcastle is smaller (as it was designed only for 512Kb L2 cache). A disabled Clawhammer (or any clawhammer for that matter) has a larger core.
As for the FX55 my take on it being 130nm at launch is due to issues with yields - I personally believe 90nm will launch as mid range frequencies and once they perfect the process then you will see the 4000+ and FX55 or 57.
A Clawhammer core with 512kb of L2 cache disabled is still a Clawhammer core.Quote:

The New NewCastle Core
http://www.xbitlabs.com/images/cpu/a...3800/wafer.png
"Really, the ClawHammer core with its 1MB of L2 cache has a die size of about 193 sq. mm. The reduction of the amount of L2 cache memory allows reducing the die size to 144 sq. mm."
"As you see, one 200mm wafer contains either 144 ClawHammer cores with 1MB L2 cache, or 194 NewCastle cores with 512KB L2 cache. Thus, the use of the NewCastle core allows increasing the yield of processor cores by 34% from one wafer! This means that the manufacturing cost of one NewCastle core is about 25% lower than that of a ClawHammer core"
http://www.xbitlabs.com/articles/cpu...64-3800_4.html
Actually AMD themselves have said that the FX55 will be at 130nm.
i stand corrected. ;)
does anyone out there have one of these half cache clawhammers?
I had two. A 3000+ that topped out around 2.3ghz, and a 2800+ that maxed at about 2.25ghz.
hmm wow 512 kb of l2 cache can beat a new castle 200 mhz ahead??? consistently in all benchmarks??? well i want one that can oc really high 2.5-2.7 ghz on phase change
Nice info, some benchmarks any1? I am really looking forward to see, how good they will clock. But i think they will go for yields first, so there wont be much headroom for this. Anyway saves with that much smaller cores will be huge and when 90nm will be more mature, 1MB chips or duals will be here just in time. And with latest Intel price cuts and so, i think theese Christmas going to be *good* for us...
welcome termix :toast:
unfortunately the only 1mb chips right now is the S754 Clawhammers which are going fast if not already gone and the S939 FX chips, the standard S939 chips are only 512 and im sure it will always be that way
dual cores are due out 2H of 05
90nm is right around the corner though, im going to start saving up for an fx 57 right now :p
not consistantly, sometimes its less, but that seems a good estimate.Quote:

ocmyface - i posted a link to that same exact roadmap in the 2nd post of the thread... :rolleyes:
chill out man :stick:
god FORBID the same link be posted twice!!
i fail to see where i indicated that i was mad?
either way, i wouldnt buy a fx-57 straight away, as the better yields are rarely the first ones. unless you got loads of money ;)
i guess i read your :rolleyes: wrong, rolleyes where i come from means dumbass
and itll be a LONG time before i can dish out enough for an FX-57 ;)
heh, guess you wont have to worry about those "crappy" first yields ;)
ok maybe you read the :rolleyes: right, i just didnt mean to be so harsh as you took it though ;)
I want to see one of these Oakville processors. Does anyone know of a distributor that might have access to them? I asked amd about it, and one of their reps said the mobile processors were never intended to be sold to the public by themselves. He said they were leaked from distributors to online resellers like newegg. THe mobile amd 64's like the oakville are suppose to go to places like HP and Compaq, etc. But there must be some way to get them.
Actually in games the 200mhz means much more then another 512k of cache , with the expection of doom3 which realy likes big cache.
anyway about the naming - it is not that simple http://www.xtremesystems.org/forums/...threadid=41102
even AMD is not sure what each chip is called.

my 2800+ was a 512k claw that did 2.23GHz for 3dmark 2001
"better hurry up before the clawhammers are gone for good.. i'm glad I bought mine"
and what does yours get? my 3200+ newcastle is faster at 2.6GHz ;) :D
"FX57 will be one hell of a chip to own"
90nm, 2.8 with air cooled clocks to like 3.3-3.5 and casade coolings to mid 4GHz. LOL isnt that funny that now amd is catching up to Intel in real MHz? imagine a 2.8c p4 and a 2.8GHz fx57, both overclocked to 3.5GHz oh LOL the a64 will be like twice the speed! :ROTL: :lol:

thats why amd choose to add 200MHz to the newcastle but reduce the cache by half. Its much cheaper to speed bin higher clocks than have more cache. also amd's yields of 2.2 and 2.4GHz newcastles are good enough that it was worth losing 512k cache for. The only claws amd still makes are the rare 3700+ which are way overpriced and not many around either. Might as well pay a bit more for a fx53 anyway.
"Actually in games the 200mhz means much more then another 512k of cache"
the claw may be 200, even 250MHz ahead of the castle in 3dmark 2001, especially with an x800 card but in games the difference shrinks to 100-150MHz or so. Thus If I buy a claw, it might gain me another 300 marks at say 2.5GHz clocks but it would be a sidegrade to my 2.6GHz castle in games however.
I have one and it does 254htt x 10 = 2.54. Its a 3000+ claw with just 512k cache. I like it! Thank you agp locks! :DQuote:

AMD know the internal code names of each chip. But some of their employees are not sure what each chip is called.Quote:

Sorry, for reactivating this old thread.
Just wanted to let you know that these oakville CPUs are available NOW!!!
I just relized that lol. GF was talking about highly priced A64 3700 and I'm thinking...over priced the things are like 450bucks :S lol
