PPC vs x86, Intel vs AMD, believe me folks I´d like to see PPC rule the market, but this looks like x86 is here to stay. 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 7 of 41 | ANN.lu |
| Posted by Graham on 28-Aug-2001 22:00 GMT | In reply to Comment 2 (Hans-Joerg Frieden):
The P4 has 20 pipeline stages. The 3.5GHz P4 they showed off will have 20 pipeline stages. The shrink to 0.13u, plus some killer cooling system will have been the reason that the demo CPU got to 3.5GHz.
Anyway, 1 year is 2/3rd of a Moore's Law period (yes, I know it is about transistors, not clock speed, but in the end it has been roughly the same). Today: 2GHz. 2/3rd of 2 is 1.333, which makes a speed of 3.333GHz in 1 year's time anyway. Nothing special there.
Intel are going for reduced IPC and higher speeds in a cyncical and consumer-tricking move. AMD are going for IPC - the Clawhammer apparently has 50% more IPC than the Athlon! If a 1.4GHz Athlon can match a 2GHz P4, then a 2GHz Clawhammer will more than match a 3.5GHz P4.
The Athlon will only be at 1.6GHz at the end of this year, when Intel will be at 2.2GHz. The G4+ will be at 1GHz. Lets hope that next year the PPC will gain some massive speed gains with the G5, although 2GHz looks to be the limit for next year already.
The fact is, to get huge speeds, you need more pipeline stages. However, speed doesn't mean power, as the P4 has demonstrated by having an appalling IPC compared to the Athlon, the PIII and the G3 and G4. |
