I think it´s interesting to see what will be tomorrow, even if it has little to do with Amiga today. Yes, I know that GHz isn´t everything, but that´s a *lot* of GHz to make up for with superior (?) architecture... From Heise Online:

"In the early morning, shortly after 8 AM local time, [Intel] presented a prototype of a 0.13µm Pentium-4 (Northwood), which - shortly - ran at 3.5 GHz.

On average, the IDF record breaking CPUs reach the market after roughly a year. The 2 GHz type that started production yesterday was also presented as a prototype on last year´s IDF. So we can expect the 3.5 GHz Pentium 4 in late summer 2002. In general, so Otellini, the architecture can be scaled up to 10 GHz."

Pentium IV Prototype at 3.5 GHz : Comment 33 of 41ANN.lu

In reply to Comment 13 (Graham):
> The i850 chipset also supports Socket 478, btw.
Yep, I know, but at the last I checked, all motherboards I could find for the 478 were based around the i845 chipset. As of 2 weeks ago, all of Intels own motherboards that I saw were also based around the i845. Looks as though I stand corrected here now as there are now 478/i850 motherboards available.
> The tests I have seen put a 1.4GHz Athlon at about the speed of a P4 2GHz on i850 with socket 478. The P4 wins media benchmarks, Quake III and memory bandwidth, the Athlon everything else, for 1/5th the price.
Check out http://www.tech-report.com/reviews/2001q3/pentium4-2ghz/index.x?pg=1
Their conclusion is that the P4 2GHz is actually faster overall than the Athlon 1.4GHz.
> AMD will release the longer pipelined Clawhammer and Sledgehammer processors next year, which will push performance really high. Intel must be worried about that, hence their MHz push at the moment.
I don't think their over worried. When they go to Northbridge based around 0.13 micron fabrication that should allow them to bump up the old GHz a bit. Besides, lengthening a pipeline will take some of the edge out of the new AMD chips. If Intel can pull off further speed increases without further pipeline increases, then they may be in an ok position.
> Shame that the market is in a slump, eh?
Oh, such a shame :-)
<<The new P4's (socket 478) are utter shit, as they use Intels 845 chipset, so using SDR DRAM.>>
> Wrong. i850 supports both S423 and S478. i845 supports both S423 and S478.
Yep, once again I knew that both chipsets supported each of the chips, but I was basing my argument on what was available in terms of motherboards at the time. I see now that i850 m/b's are now available for the 478, so again, stand corrected.
<<Tests have shown that 2G pentiums (478) are no better whatsoever than the Athlons.>>
> Tests have shown that a 1.8GHz P4 on i845 performs like a 1.2GHz Athlon if it is lucky. P4 + SDRAMcrap.
Yep, that's what I was basing my original argument on. Looks as though the 478 is pretty successful with rambus though.
<<But in 6 months time, there'll be another revision of the Pentium which'll use DDR DRAM.>>
> You mean now, don't you? And it isn't the processor that supports RDRAM or DDRRAM, it is the chipset. VIA P4X266 supports PC2100 DDR RAM. i845DDR only supports PC1600... SiS645 supports PC2700 DDR RAM!
No, what I was referring to is that Intel were not releasing licenses to use DDR supporting chipsets. There was speculation saying that this would probably become available when Northbridge chips become available. I think it was Via who were saying that they would produce a compatible chipset without a licence from Intel and worry about it later (at least, I'm pretty sure that was correct as of two weeks ago).
> Yes, and AMD will have 1.53GHz Palomino Athlons out in the first week of October, which will be equivalent to a 2.2GHz P4. Palomino supports SSE and prefetch, hence it will have even better performance.
2.2Ghz P4 are already out. By October I reckon that we'll be seeing even higher clocked Pentiums. Interesting to see which'll be the fastest in real terms. Then we'll see Northbridge (and I've seen speeds touted as being in excess of 3GHz).
>Increase in memory bandwidth can increase framerate. Usage of SSE and SSE2 instructions can increase framerate. Increase of MHz when using the same processor can increase framerate.
I totally agree, but MHz (or GHz as the case may be) is an easy number to sell to people. In terms of performance, the proposed increase in P4 cache sizes may also go quite a way in offseting the new Athlon technology. From what I've seen so far, Intel have the edge. Time will tell if they keep it...
