Clawhammer vs Sledgehammer

[gweminence]

I'm looking to buy an athlon 4000+, and notice that there's a Clawhammer core and a Sledgehammer core, so I'm wondering what the difference is, and which is better, etc...

As long as I'm at it, what about the Winchester core? Thanks in advance for any response!

Clawhammer vs. Sledgehammer I'm not certain on. Maybe Sledge is dual channel while Claw is single channel, because IIRC they both have 1MB cache and are 130nm chips, in which case the Clawhammer label is a misprint.

The Winchester cores (available at 3000+, 3200+, and 3500+; the best values of which are the former two) are 90nm and run slightly cooler. They've been known to reach 2.7GHz on air cooling, and very high on stock cooling and often stock voltage. Zebo made a post today about some week 48 Winchester that achieved 3 GHz on some sort of air cooling.

Clawhammer is the code name for the first Athlon 64 (745), Sledgehammer is the opteron core/Fx IIRC.

That site is clueless.. 4000 is always a sledgehammer

Clawhammer = Single channel 1mb lvl 2 (3000, 3200, 3400, 3700) *all claws came with 1mb lvl2 but AMD crippled some early ones by disableing 512.. they are the early C0 revs 2800 and 3000 w/ 512 kb lvl2.

Sledgehammer = Dual channel 1mb lvl2 (all opterons, FX's, 4000)


Really both are same core 130nm SOI and 193mm2 Clawhammer has one of it's mem controllers disabled.

If it's a Sledge, it's a modified one as the original Sledgehammers required registered ram.

Clawhammer has one of it's mem controllers disabled.

Never heard that one but if true...

Yes, but registered RAM wasn't a condition determining the core.

This makes perfect sense, because all Clawhammers were S754. That's a single-channel platform.

Thanks for your responses guys...so, to sum up, sledgehammer is the ONLY 4000+ core, and it's inherently better than clawhammer in any case...is that right?
