The P4X800 supports DDR II, and will sample during the second half of this year.

Hummm, maybe DDRII is closer than we thought.

The P4X600 supports 128-bit 266 and 333MHz double data rate (DDR) memory, has a choice of AGP2X/4X and 8X, as well as 8X V-Link, with production slated for the second quarter of this year.

Dual channel DDR in the house, and with DDR333 to boot. This will be interesting to watch, especially with the legal dispute factors...

And its Hammer chipset, the K8HTB, with AGP 4X/8X and an 8X V-Link throughput, is set to go sampling this April....

ClawHammer chipset to sample in April? Interesting how VIA will have a full ClawHammer board sampling 7-8 months before the ClawHammer 3400+ is supposedly scheduled to be released? If this is indeed true, I definitely think ClawHammer will hit before the end of the year. To my knowledge, it doesn't take 7-8 months for a chipset to become ready for the market...
 
AGodspeed, you don't serisouly think Via is not going to have any problem with ClawHammer? There will be fine tuning and ramping up the production. I seriouly hope Via is not going to do the same as it did with Athlon launch, the chipset came out 5 months after the launch of the processors.
 


<< Here's something more interesting: are any RDRAM supporting chipsets coming to the AMD side? >>



I would highl;y doubt that - unless hammer or any new versions of the Athlon need extreamly high bandwidth - which I don't think will ever happen.

Actually, no, the situation today is different from the situation at the Athlon launch. If you remember correctly, big old Intel was throwing around its weight by telling companies like VIA et al not to produce Athlon based chipsets and motherboards. That's the main reason it took VIA quite a while to get out their Athlon chipset. Not only that, but VIA was not nearly as big back at the Athlon launch as it is now, and that means that VIA today is definitely more able to release chipsets to the market faster than in the Athlon days.

The situation is quite different now compard to 2-3 years ago Agent004.

The hammer is bowing with a 200MHz 64-bit), double-pumped fsb, which translates to 3.2GB/sec of available bandwidth (same as current P4, less than P4 fsb refresh). Therefore, especially given the high prices of DDR SDRAM now, RDRAM makes a lot of sense.
 
I agreed that the situation is quite different now, that's why I said I hope it doesn't do that. Moreover, I don't like Via's quick 'A' revisions, ie release a lower, buggier chipset and then a newer vision 2 month laters. Seems like a trend, seeing the same with KT333, as Via is pushing ahead with it. I want the 'A' revision at the launch🙂

Perhaps that's why they are sampling right now :Q
 


<< Do you guys think AMD will release it's own chipset for Hammer? >>

AMD's official line is that their own version of the ClawHammer chipset will be ready to go at the ClawHammer's launch.

I agreed, I mean the only thing that's holding the current XP back is the bandwidth/fsb. Since Clawhammer has prefetch, it would allow a lot of head room.

I understand whay you're saying Agent004. I will likely not purchase a K8 VIA chipset at launch when I can get an AMD chipset instead.
 
"RDRAM makes a lot of sense. "

I disagree. The extra latency penalty of RDRAM is not worth it and would not perform as well on the Athlon as it does the on the P4. The P4's architecture is designed to hide the latencies that RDRAM has, and the Athlon/Hammer is not. Faster DDR makes more sense..or maybe even dual channel like on the Nforce.



"Since Clawhammer has prefetch, it would allow a lot of head room. "

The first generation and second generation MP CPU's, as well as the Athlon XP, mobile Athlon 4, and the new Duron core all have hardware prefetch already.

i think that is doubtful with the integrated memory controller built into the hammer , i could be wrong though
