Athlon 64.....newcastle and claw hammer

[otispunkmeyer]

im buyin a A64 cpu soon

i was lookin at the 3000, but now the prices ahve come down abit i started glancing at the 3200

my frined has a 3200 ..2 GHZ and 1mb cache, a clawhammer.....the 3000 basically was the same with half the cache yes?

now i see that there is a 3200 with same cache of 512kb but now 2.2ghz to give it performance over the 3000

is the 3000's on sale now still clawhammers....or were they newcastles all along? i want the newer revision if possible so does this mean im gonna have to go for the 3200 newcastle?

 

[otispunkmeyer]

bump?

 

[otispunkmeyer]

anyone

I'm confused but so are you it seems.

The 3200 with 1MB cache is the Clawhammer (2.0ghz)
The 3200 with 512kb cache is the Newcastle (2.2ghz)

If you are asking which one is better, it's the Newcastle as cache doesn't play such a large part on A64s.

i jus wanted to know if the 3000 is also a newcastle? or is it a claw?

If the A64 3000 has 512K cache then it's a newcastle.
With out that knowledge, I'd probably assume it's a newcastle anyway.
AMD didn't release anything below A64 3200 until the newcastle core came out.

Newcastle vs Clawhammer CO vs Clawhammer CG.
(Newcastles all come with the CG revision)

In terms of stock performance:
Newcastle > Clawhammer CG ~= Clawhammer CO.

The newcastle gives up 512K of L2 cache, but gets an extra 200MHz.
Since A64s aren't bandwidth starved, the extra MHz makes more of a differences.
The main difference between the CG and CO revisions is the memory controller.
Stock performance really doesn't change much between revisions.

In terms of overclocking performance: (this one is debatable)
Clawhammer CG > Newcastle > Clawhammer CO.

From what I've been reading, people have been hitting roughly the same top speed on the Newcastles and the Clawhammer CGs.
At the same speed, the extra cache pushes the clawhammer CG over the top.
Clawhammer CO doesn't overclock as well, presumably because of the memory controller.

That's my take on the issue.

Not all newcastles are CG steppings if the statement below is true.

The new 3000's are probably/likely Newcastles. Although it's debatable (unless you work for AMD or in the know) that the early 3000's are either Newcastles or Clawhammers w/ half the cache disabled from 3200's that didn't make the cut for full use of 1 MB of cache.

No matter what you get.... an Athlon64 rocks!
I'd go with the Newcastle 3400+
I personally own a ClawHammer 3200+ 1MB Cache
And i dont OC so it aint really an issue to me
again
no matter what your sittin on a very nice cpu

there are both Newcastle and ClawHammer 3000+'s. The ClawHammer 3000's are the ones with 1MB of cache, but 512k disabled. The Clawhammer 3000's tend to have older steppings, C0 and earlier (if possible). The Newcastle 3000's are all CG.

anyays, since it's now August and the 3000 has been selling for about 6 mths ... most 3000's on the shelves of stores should be Newcastle CG's unless the store owner closed his store 4 months ago and just re-opened it now
