Question on SIS655

[neoro]

Granite Bay
It says it can feed the Pentium 4 the needs of 4.2GB/s Bandwidth....... with dual DDR266

SIS 655 with Dual DDR333
with surely exceed the need of the Current P4 3.06Ghz..
Would there be any use if i get a mobo with Dual channel ddr 333 if i am going to get a P4 3.06 HT??

Will there be any performance increase.....

remains to be seen....but i think that SiS655 will outperform Granite bay at default speeds and hopefully we will see mobos that offer good overclock features so that it will overclock as good as the Granite bays!

Springdale-P Q1 2003 will offer 333 support But the real keeper seems to be Springdale-PE DDR400 support 800Mhz also Q1 2003.

nah, i think that canterwood looks better,especially with that 'turbo' mode😀

well you will have to wait until Q2 2003 for the turbo and ECC Memory support goodies. 😉

Integrated Graphics, not my first choice either.

If SiS outperforms Intel, it will be a first. Intel has been faster @ DDR 266, 333 speeds so far. Intel 845x chipsets have also been the only ones able to reliably run above DDR400 speeds as well. In theory, DC DDR333 should not have any advantage over DC DDR266. If anything, the asynchronous memory timing would pose a performance penalty.

Well not really, even at DDR333 SiS648 has been on pair even with i845PE at DDR400 (async) SiS have had the fastest DDR platforms. Infact SiS648 DDR400 has been on pair with 850E-PC1066. And when SiS645DX was released it was the fastest DDR chipset at the time (if i remember correctly SiS645 was the first with DDR for the P4 perhaps VIA had a board also at the same time?)

Anyway here is a review with SiS648-DDR333/400 and 845PE-DDR333 845G-DDR333 and i850E (running 1066 Rambus)
Big Power in a Small Package

At Default speeds SiS have been faster more then ones, but when it comes to overclocking there hasen't been a wide variety of boards to choose from that supports ex. AGP/PCI lock for the sischipset, except Gigabyte 8SG667 that i know of. Hopefully we will have more OC boards for the 655.

Now what i want to see is Granite Bay tit to tit with SiS655 😀

Every bench I have seen shows SiS beating Intel only when clocked at a faster mem speed. SiS DDR 333 faster than Intel DDD 266, SiS DDR 400 faster than Intel DDD 333 etc. When the DDR speed is the same, the Intel 845x platforms are on top, SiS 2nd, VIA, last. Intel is also the only P4 chipset that can reliably run high (DDR400+) speeds with any stability.

Again, in theory, DC DDR 333 should have no advantage over DC DDR 266. Once the reviews come out, we will know for certain.

I think that it will be no doubt,the 655 will be no faster than E7205. DCDDR333 on the 533fsb is no different than DDR333 or DDR400 on the Athlon XP's 266fsb. There just is no need for that bandwidth. There is only one memory/fsb solution where there was more memory than fsb bandwidth where there is a significant advantage in performance, that's nForce2 with DualDDR333/400 (see Anandtech's nForce2 Part II Digging Deeper article for that), but that is solely because of the nForce2's DASP II, which SiS 655 lacks.

The link i provided will show you that SiS648 mem at DDR333 ~ Intel845x DDR333.

Again, in theory, DC DDR 333 should have no advantage over DC DDR 266. Once the reviews come out, we will know for certain.

I Agree.
