SPEC CPU 2000(SpecInt) for AMD K8 "ClawHammer"

[System]

also shows how pathetic the power4 is hahahahahah 800.,...omg...hahahaha

Is that in Gigs? Because it looks very similar to AMD's naming convention to hide the fact their CPUI's arnt as fast as Intels.

Can see "Ghz" or "Mhz" after the numbers?  Notice "+" character.

AMD has stated that the K8 would need to reach at least 2.6 Ghz to score a rating of 3400+.

Yes, you may have noticed AMD started labeling their CPUs not in Gigs but 1300+ or something similar. 1300 pluss does not mean CPU Mhz or Ghz, its simply a marketing ploy.

The rating's purpose is only for comparing with the older K7 Athlon Thunderbirds.

Applying anything else is a mistake.

AMD's naming convention to hide the fact their CPUI's arnt as fast as Intels.

They are not as fast in terms Mhz speed. The real performance indicators are IPC + Cycle speed.

.

True but they are marketing to people who are absolutely clueless, so I understand why they do it. At least when AMD labels with 1900+ or whatever, it really is as fast or faster than a P4 at the same speed, unlike when Cyrix used to do the same thing.

Cyrix obtained it’s PR rating via a narrow benchmark i.e. Winstone.

AMD obtains it’s rating by using wider range of benchmark tests which range from integer to floating point applications.

Yeah their nameing convention is stupid.
they 'SAY" its a powermark relative to the t-birds that didnt have SSE2.....

Tbirds doesn't have any core improvements like XP core.

but we all know its to show relative performance to intel cpu's......
now that haveing been said.
The clawhammer is a 3400+
The P4 is a 3000mhz P4
(a fair benchmark would be to benchmark a Clawhammer 3000+ against the P4 at 3000mhz since AMD's useing this power rateing instead of mhz in this rateing their faster chip beats the P4 yeah but its not compareing a 3400mhz P4 to it)

“3400+” is just model number” paraphrasing from AMD.

Also dont forget that AMD's Clawhammer is 64bit that Intel P4 is 32bit...that fact that the gap is so small considering the AMD is both 64bit and 400 power rateing points ahead with such a small lead looks bad.

Pentium 4 can already handle 64bit wide instructions size, but can’t address in  64bits.  

No need to worry about Intel’s fortunes since it’s Intel will release a slightly improved Pentium 4 Prescott core starting at ~+3.0 Ghz.

It´s true that some apps, like Lightwave, are
slightly faster on Intel than on AMD, but Intel
are not cheap if you compare to AMD. As a test to
get Screamernet working I rendered a frame on
an P4 2 GHz and the same frame on an AMD 1700+.

The P4 got the work done in 4 minutes, where the
AMD was slightly slower, ended up at 6 min. But as
a friend told me: "If you want speed out of Lightwave,
go for Intel, as LW is optimized for this processor."

With “Cinema 4D R7” the scenario is opposite i.e. AMD is faster than Intel Pentium 4 in a given per cycle.

[Hammer]

AFAIK, AMD's biggest problem is that they can't pump the clock speed of the Athon much further.

K7 core is old compared to the newer Pentium 4 core* (designed to clock well beyond 2Ghz).

AMD's K7 core has reached scenario that plague Intel’s Pentium III core.  It’s AMD’s turn to introduce a new core.

AMD has stated that; IF K8(clawhammer) is to reach 3400+ rating it must travel at least 2.6 Ghz.

*Northwood core Ghz's peak range is at ~2.8~3Ghz.
*Prescott core is design to exceed 3Ghz range.

G5 information (in case someone is interested)
http://www.theregister.co.uk/content/archive/23158.html

The estimate for G5 is
 GHz -------------- 1.2 ----- 1.4 ---- 1.6
SpecInt2000 --- 987 --- 1151 -- 1340
SpecFP2000 -- 1005 -- 1173 -- 1359


http://www.theregister.co.uk/content/39/22328.html


And as far as I know G5 core microcontroller chips are shipping from Motorolla.... way below those performance figures...

[Hattig]

AMD have not said that, some idiot on a website said that is would be 2.6GHz for 3400+. AMD have said nothing about clockspeeds for Hammer and how they relate to the performance rating. All they have said is 2GHz+ for 3400+ rating.

It looks likely that 2.2GHz will receive the 3400+ rating.

AMD are going to release the 2400+ and 2600+ Athlon TBred's next week according to The Inquirer. That is 2GHz and 2.133GHz. Intel will release the 2.8GHz P4 a week later.

Edit: Also, the G5 core controller chips (8500) run at 500MHz, so no wonder they perform a lot lower than the to be released desktop version! Probably have lot smaller caches, perhaps less execution units, etc.

well, how about this link: titanium vs clawhammer?

@Hattig

I did indicate that the source is not verified.

Non-speculation information will be noted; anything else is speculation from various websites.

@ksk

Have you confirmed the existence of G5 processor from Motorola via email?

Did CEO Steve Jobs actually unveiled desktop Power Mac G5s running at 1.2, 1.4 and 1.6GHz? (News was posted @ 03/12/2001, expo was stated to be @ January 2002)?
