Power mac g5 vs pentium 4

A common problem amongst single processor G5s was that the plate of metal soldered to the Logic Board connecting all eight of the RAM slots would, over time, expand and contract in such a way that the computer could not boot properly, as it would not detect any RAM. The only way known to fix this problem is for someone to re-solder the plate themselves or expose the other side of the Logic Board to heat from a heat gun.

The latter of these two options is far easier, as to access the plate of metal one would have to completely remove the Logic Board from the computer, whereas all one has to do to expose the other side is remove a fan. All 2. This was a bold step for Apple, and should have allowed the use of very fast processors, giving Apple an advantage in both the performance and reliability race, but the system turned out to be subject to coolant leakage. While leakage was sometimes detectable by drops of green coolant in or beneath the machine, in many [ vague ] machines the seepage is so slight that it was almost impossible to detect without dismantling the entire computer.

Later models only the 2. The liquid cooling system fits into the case where the heat sinks would normally go, so there is no easy way to distinguish the liquid-cooled versions from the air-cooled, although most, but not all, [ vague ] of the liquid-cooled machines have a sticker inside warning about the possibility of leakage.

Semi had formed a tight relationship with Apple, which would result in P. Semi promptly delivering processor chips for Apple's personal computer notebook line and possibly desktops. The processor that would run the personal computers was P. The sampled chip also has lower heat intensity than Intel's Core Duo , which gives off 9—31 W under normal load.

According to The Register article, P. Semi executives believed that they were all but assured of winning Apple's contract, and CEO Dan Dobberpuhl thought that Apple's hints of moving to Intel were just a persuading tactic. At the time, the companies were working for PWRficient software. Despite the advantages of more compatible architecture, Apple moved to the Intel architecture officially for 'performance-per-watt' reasons.

However, P. Semi would not be able to ship its low-power multicore product in volume until , which, combined with P. Semi's status as a start-up company, seems to have been the final blow to the development of Power Mac computers. However, it was also speculated that Apple switched to Intel processor because Apple could no longer abide the constant delays in performance ramp up, [15] desired native Windows compatibility, or it was Apple's strategy to shift its business focus away from desktop computing to iPod and subsequently iOS development.

Or did they just not tell the whole truth? He also notes later ad campaigns claiming the G4 was faster than the then-current Pentium III, that the G5 was more powerful than the Pentium 4, and so on. Since then, Apple has replaced PowerPC-based Macs with Intel models across the product line, claiming its new Intel-powered models are twice as fast as the previous PowerPC equivalents.

Part of the problem is that the CPU landscape has never been static. In the mids, PowerPC and Pentium-family clock speeds ran pretty much neck and neck. There was reality behind it. However, Intel was able to ramp up the clock speed of the Pentium 4 architecture more easily.

Reviewers noted that the first generation P4s were not much more powerful than the P3s they replaced — but they ran at a higher clock speed, making them appear more powerful. Intel-competitor AMD stopped referring to its more-efficient CPUs by their actual clock speeds, naming models after the higher clock speeds of a presumably equivalent Intel model. The key words here were up to. Inevitably the Mac won, often by a large margin, even if it had a CPU with a slower clock speed.

These bits of processor design can make a huge difference in performance — but only when program code is compiled to make use of them. Is that because XP is much faster or more efficient? Not really. XP displays the desktop relatively quickly, but then it pauses, not letting the user actually get anything done while it continues to load.

Back to Intel — for several years, Intel pushed the Pentium 4 architecture to faster and faster speeds. At a time when P4 systems were running at 3 GHz or faster, these Centrino systems were being advertised with speeds in the 1. Yet the Centrino models were typically priced higher than apparently faster by clock speed Pentium 4 systems.
