the P4 is dead!

Also, the P4 is starting off at 1.4GHz or something up there like that, which mean the core will be most likely scale-able out the wazoo. Who knows, we'll just have to wait and see.

I thought the p4 is going to run on a qdr bus, which will mean that a 1000mhz bus will essentially be a 4000 mhz bus, not that anything would run those speeds of a bus in the near future.

 

[BurntKooshie]

you're right. Its a 100mhz bus, quad pumped. 64-bits wide. 64 * 100 * 4 = 3.2gbytes/second bandwidth. damn, that means I did my math up above wrong. If they were to do a quad 133mhz bus, then my above statement is correct, but, its not 😱

I still think Intel's QDR-implementation belongs on a videocard. Its hard to imagine PC's needing so much internal bandwidth.

 

[BurntKooshie]

yes, it does. and, no its not. massive bandwidth always helps. Especially with large FPU code and data.

 

[KarsinTheHutt]

Games like Q3 are supposedly system bandwidth limited.

 

[BFG10K]

It will have 12.8(!!!)gbytes/second of bandwidth. With nice latency. So RAMBUS isn't terrible technology.

You must be joking. Where did you hear this from?

The GF2 Ultra with 4 ns DDR RAM running at 460 MHz has 7.4 GB/sec memory bandwidth while overclocking it to 500 MHz yields 8 GB/sec bandwidth.

If your RAMBUS theory were correct it would mean that desktop memory would be 1.5 x faster than the fastest (and most expensive) available DDR RAM used on video cards.

Even if it were true, how much would this cost? $2000 for a 128 MB RIMM?

If I remember right, I saw on JCs that the P4 will debut at 1.4 - 1.5GHz, with 1.7GHz+ in Q1/2001, and 2GHz+ in Q2/2001.


If AMD can keep up, the P4 will most likely be dead in the water.

I'd be willing to bet that AMD could release a 1.4GHz Thunderbird on current process technology, maybe with a little tweaking. At least 1.3GHz. When Mustang comes out, with it's slightly longer pipeline, and hopefully other tweaks, I bet it could do 1.5-1.7GHz. Sledgehammer will supposedly do 2GHz+. So unless the P4 can ramp to like 3GHz+, I don't think AMD is out of the MHz race, at all.
