Petz,
How do these benchmarks for the K6-2-450 jive with your projections?
processor.org
K6-2 350Mhz at 450Mhz: we've done it!!!
Oh happy day! I just got a K6-2 350Mhz unit and plugged it in my computer. I wasn't expecting
much from this chip, because I already had a K6-2 at 112x3 (which is faster than 100x3.5 for
most apps anyway). However, I was wrong - this chip turned out to be a pleasant surprise!
First of all, let me tell you that I didn't use any special cooling devices. No Kryotech was
needed to overclock this little chip (now that makes me wonder how much I would've got with
a Kryotech cooler). All I'm using is my faithful 12-buck huge Vantec fan/heatsink combo, which
was the same one used for pushing a K6-2 300Mhz unit to 112x3.5 (392Mhz) a few months
ago!
At 112x4 (448Mhz), this chip is faster than Celeron A at 100x4.5! Both were using the same
configuration, ie. 128Mb of PC100 sdram, a 4.3Gb UDMA HDD, a 12Mb Diamond Monster II
and an old 4Mb Diamond 3000 PCI, except for the fact that the Celeron A was running on a
shiny new Abit BH6 motherboard, and the K6-2 was running at my faithful Soyo 5EH/M. Here
are the scores:
CPU
Business
Winstone 98:
K6-2 450Mhz
(112x4)
31.0
K6-2 450Mhz
(100x4.5)
29.1
Celeron(A)
450Mhz (100x4.5)
29.3
What's interesting about these scores is that the slight advantage of the Celeron at equaly
settings is gone when we set the K6-2 at 112x4, thanks to the flexibility of being able to switch
the multipliers in the K6-2.
Now here are the 3DWinbench scores:
CPU
3D Winbench
98:
K6-2 450Mhz
(112x4)
1367
K6-2 450Mhz
(100x4.5)
1329
Celeron(A)
450Mhz (100x4.5)
997
As you can see, with the 3DNow! support, the K6-2 at 112x4 (once again, thanks to the
flexibility of the non-locked multipliers) can be up to 37% faster than the Celeron A under
DirectX (keep in mind that DirectX 6.0 is required for 3DNow! support). This clearly shows us
how 3DNow! can make quite a difference in the K6-2's otherwise weaker 3D performance.
At the same settings, the K6-2 450Mhz was still more than 33% faster with 3DNow! support.
We will soon be publishing the scores under Quake II and Unreal, as well as more
business-oriented benchmarks!
Please note that 450Mhz with the K6-2 350Mhz is not an almost-certain overclock like the
Celeron 300A at 450Mhz is, however, most of the K6-2 350Mhz we've seen had no problems
reaching up to 400Mhz! As you can see, the Celeron A currently remains the best bang for
the buck, but the K6-2 is still a strong player!
