JE sais pas si c'est déjà paru sur les forums ou en news de macgénération, mais Think Secret a publié des benchs des premiers macs avec processeur Intel. D'après l'article, c'est uniquement des perfs avec Rosetta. Je suis pas un spécialiste, mais pour une première version, je trouve pas ça si mal. Le G5 bat le P4 3.6GHz dans un certains nombres de tests mais Intel se défend sur d'autres.

Overall, the Intel Mac are scoring between 65 and 70 with Xbench, a far cry from the 200+ scores higher-end G5 systems reach. The CPU test is landing in the high teens compared with scores of 100 to 200 for G5 systems, but that appears to be primarily due to lackluster FPU scores. According to a recent Macworld story, Rosetta does not support AltiVec instructions, which substanties the results. The GCD Loop score for the Intel Mac, part of the CPU test, is a respectable 110, compared to dual-2.5GHz G5 Macs that score about 140.
The Intel Mac performed substantially less well than the dual-2.5GHz G5 at Thread test, scoring an 82 compared to 225. In the Computation Thread test the Intel Mac scored a respectable 110 compared to 155 in the G5, but the G5 blew the doors of the Intel Mac in the Lock Contention test, scoring a 420 to the Intel Mac's 66.
The Memory Test tells a similar story: overall the Intel Mac scored a 214 to the G5's 378, but the Intel Mac actually exceeded the G5's Stream Memory Test: 351 to 319. The G5 trounces the Intel Mac at the system memory test, however, scoring a 464 while the Intel Mac musters a 154.
The Intel Mac scored a 125 on the Interface Test, compared to a 380 for the G5.
The Intel Mac scored well in both the Quartz graphics and OpenGL graphics tests—almost matching or exceeding dual-2.5GHz G5 score—although it's unknown which video card is powering the system. There has been some speculation that Apple's emracement of Intel processors will also allow the company to take advantage of off-the-shelf PC video cards.
