Van Smith van Tom's Hardware Guide heeft een kort artikel geschreven over de performance van de Pentium 4 zoals Intel die heeft voorgeschoteld op het Intel Developer Forum. De chipbakker claimde namelijk dat een 1.4GHz P4 anderhalf keer zo snel zou zijn dan een 1GHz P3 onder de Windows Media Encoder benchmark. Dit zou een winst van ongeveer 7% procent betekenen op een clock-for clock basis. Aangezien de gebruikte benchmark erg afhankelijk is van de beschikbare bandbreedte (en dus in principe een best-case scenario is) is dit vrij tegenvallend te noemen. Er wordt daarom vooralsnog voorspelt dat de P4 het wel eens zeer moeilijk kan gaan krijgen tegenover de 1.5GHz Athlon systemen met DDR chipsets die eerder al betere winstresultaten lieten zien:
Although it is much to early to write off the P4, our intuition leads us to believe that the Intel Pentium 4, already dogged with much higher production costs due to its mammoth die size, will have a difficult time standing toe to toe with 1.5 GHz DDR SDRAM AMD Athlon systems which should arrive almost simultaneously with 1.5 GHz P4 machines late this year to early next year. This P4 will likely especially suffer on nearly all legacy applications. Those programs that are optimized to take advantage of SSE2 will likely perform significantly better than non-optimized apps, but since no benchmark numbers have been offered up from Intel on this subject we will reserve speculation at this time. [break]ZDNet heeft overigens ook zo'n dergelijk artikel neergemikt. Hieronder wat quotes:[/break] At the Developer Forum, the chip maker used two near-production systems to show off the Pentium 4's multimedia capabilities, including real-time video capture and 3D graphics rendering.
"Everything is much faster, but it's not going to run as fast as a 1.5GHz Pentium III chip would, if you had that," said Steven Leibson, editor in chief of the Microprocessor Report. The current Pentium III tops out at 1.13GHz.
Slated to ship in the fourth quarter, the Pentium 4 promises higher clock speeds -- including 1.3GHz, 1.4GHz and 1.5GHz early next year -- but analysts said it would not blow Pentium III out of the water.
In fact, compared with a Pentium III chip at the same clock speed, the Pentium 4 could run up to 20 percent slower, some analysts said. Although its clock speed doesn't necessarily translate into a doubling or tripling of performance, it will give Pentium 4 a decent boost.
