The PowerPC 604e was the first Mac processor available in a symmetric multiprocessing (SMP) configuration. The PowerPC 601 was the first Mac processor to support the 32-bit PowerPC instruction set architecture.Ī Motorola PowerPC 603 processor Processor The MC68LC040 version was less expensive because it omitted the floating-point unit. The Motorola 68040 had improved per-clock performance compared to the 68030, as well as larger instruction and data caches, and was the first Mac processor with an integrated floating-point unit. Another improvement over the 68020 was the addition of a data cache.

In Firefox, the Power Mac completed the test 27 percent faster after its upgrade the Mac mini, 30 percent faster.The Motorola 68030 was the first Mac processor with an integrated paged memory management unit, allowing for virtual memory. The Photoshop test ran about 12 percent faster after going from 512MB to 1GB on both Macs. But while doubling the RAM from 512MB to 1GB also goosed performance in both tests on both systems, the improvement was not as dramatic. We did find a dramatic performance boost when we upgraded the Mac mini’s stock 256MB of RAM to 512MB.
We then ran both the Photoshop and Firefox portions of our Speedmark test suite. As if that wasn’t enough, Apple added the biggest iMac to date to the line, a whopping 24 model with a 1920 x 1200. To simulate real-world conditions, we tested with several apps open: iTunes playing songs from its library, Firefox displaying Apple’s home page, Entourage with a well-populated inbox, Photoshop with a 50MB file open, and iMovie running a tutorial. 20 iMac (Late 2006) Industry watchers had been anticipating Apple moving the iMac to Intel’s Core 2 Duo processor, which is up to 50 more powerful (according to Apple) than the Core Duo used in the Early 2006 iMac. We then upgraded them both (the mini to 512MB and then 1GB, the Power Mac to 1GB) and retested. To find out what impact additional RAM has on performance, we tested two Macs: a 1.42GHz Mac mini with 256MB of RAM, and a 1.8GHz Power Mac G5 with 512MB. Macworld Lab Test: Bang for your RAM buck

Replacing RAM in your laptop or your Mac mini.ĮDITORS NOTE: This story has been changed from its original version, to correct the formula relating the amount of free RAM you have to the amount of physical RAM you should have. My company offers online instructions for Apple has instructions for installing RAM on many of its desktops search for Fortunately, you can find that information online. I can’t give directions for installing RAM on every Mac out there.

(Disclosure: my company sells RAM.) How do I install it? Even within the Mac community, it’s important that you buy RAM with a lifetime warranty. It’s best to buy RAM from Mac-specific companies. (OS 9 tolerated some hardware defects that OS X’s memory-management system will reject.) Bad RAM can lead to kernel panics and random application crashes. Macs tend to be pickier about good RAM than PCs, and OS X is particularly picky.

If the chart is mostly yellow and red (active and wired), then you’re running out of RAM and may experience slowdowns.īargain-basement PC retailers may offer RAM that will work in your Mac-but I wouldn’t advise buying from those sources. If the pie chart is mostly green and blue (representing free and inactive memory, respectively), then you’re in good shape. Open it up and click on the System Memory tab (see “The Colors of RAM”). The simplest way to find out whether you’re overloading your RAM is with OS X’s Activity Monitor. Inactive (blue) Memory allocated to an open program but not in use at the moment. Free (green) Memory available for allocation. Active (yellow) Processes using memory right now. But what exactly does that pie-chart (A) mean? Wired (red) Contents that must remain in physical RAM and can’t be paged out to disk. The Colors of RAMĚctivity Monitor is a great way to keep track of what applications are using your RAM (and whether it’s overtaxed). This process could take a second or two, resulting in that dreadful spinning beach ball. When you click on Mail in the Dock, the OS has to load it back into physical RAM and load that photo into virtual memory on your drive. OS X previously paged Mail out to disk, and you’ve been using Photoshop.
Let’s say you decide to check your e-mail. So as soon as you start using virtual memory instead of RAM, memory access times slow way down. DDR2 RAM has throughput of up to 4GB per second. A fast hard drive can write about 20MB per second. Paging out is slick, but there’s a catch-copying memory to disk is slow.
