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 8 of 41 | ANN.lu |

Mmmmm, a little bit hopeful. All the tests I've seen suggest that a 1.4G Athlon is roughly comparable to a 1.7G Pentium (socket 423). The Athlon convincingly wins some tests, while the Pentium wins others. I would have thought that a 2G Pentium (again, socket 423) would have a slight advantage. Reason I say socket 423 is that they use the Intel 850 chipset and so use rambus memory which has a bandwidth at the lower end of DDR DRAM (which the 1.4G Athlon uses). It has been suggested that the Athlon is only able to be comparable at the mo because it can achieve higher data rates to and from memory. The new P4's (socket 478) are utter shit, as they use Intels 845 chipset, so using SDR DRAM. Tests have shown that 2G pentiums (478) are no better whatsoever than the Athlons. They are simply crippled with bad memory transfer. But in 6 months time, there'll be another revision of the Pentium which'll use DDR DRAM. Coupled with frequencies that are supposedly going to be starting around the 2.2 to 2.4G, you may see a wider margin appearing between the Pentium and Athlon, irrespective of the 20 pipeline stages.
To the question earlier of why all the GHz, well, the GHz is a great marketing ploy. Intel have got competition so they don't rest on their laurels and continue to try to push up the numbers. Joe Public laps it up cos the bigger number chip is perceived as being better, and given the choice, he wants the better one. If Intel didn't push this way and the Athlon came up with a 3GHz chip with the Pentium stuck at 2Ghz, Intel would start to lose sales big time.
As for who would use this number of cycles, in the greatest numbers it would be the game player. Increase in CPU cycles can increase framerate (as the P4 tests have demonstrated in the main). |
