Mac mini Xbench Comparative Performance Benchmarks

The XBench test results for eight Mac OS X computer configurations are shown below. Six of the configurations are Mac mini computers with different amounts of RAM. Two are high-end PowerBook G4 computers, one running under typical, unoptimized conditions, the other optimized for maximum benchmark performance. All tests except “PowerBook 1.5Ghz 1GB RAM” were run at 1024x768 resolution. The 1.5Ghz 1GB RAM test results were taken from the peak performing 1.5GHz PowerBook listed on the comparisons page at

Higher scores are better. A score of 100 on any test shows equivalent performance to a dual-processor G4 Macintosh that was touted by Apple as 83 percent faster on Adobe Photoshop than a 1.7GHz Pentium 4 Windows PC. In every case except disk speed, the lowest-priced Mac mini configuration was over 11% faster than that reference machine, and frequently upwards of 30% faster. More expensive Mac mini configurations show 25% to 75% performance increases. As such, even the cheapest Mac mini will likely represent a performance improvement for low-end PC users who have not upgraded over the last several years.

The results also broadly suggest that an increase of Mac mini RAM from 256MB to 512MB yields a noticeable performance increase for both CPU-intensive tasks and regular use of a Mac mini’s user interface, regardless of clock speed. Mac minis use slower hard disks than the PowerBooks and therefore had lower disk speeds.

In many cases, the Mac minis outperformed the unoptimized PowerBook 1.5Ghz machine in the benchmarks despite lower CPU clock speeds; however, an ideally optimized PowerBook can outperform all competitors by some margin. For reference, a well-oiled but not perfect PowerBook will score closer to the 150 mark overall, and will not see the dramatic performance jumps indicated in the User Interface and Disk Test sections below.

Intesting isn’t it?!
Mac mini might be “entry level”, but managers to perform like a “mid level” !
I am waiting for a trip to Singapore and I will purchase a 1.42 Ghz 80Gig with extra RAM, bluetooth and Superdrive.

Just wish you had an option for a Nvidia Graphics card like the powerbooks.
I’m guessing this would be possible? They seem the same size physically?

Anybody have any reports on upgrading the Graphics card on a mini? Is it possible? If so how?

This thing will become my main work station, and replace my crappy work PC as my main computer.

A graphics card upgrade of the Mini would to mere mortals be impossible, it’s all embedded into the motherboard so unless you could find another better chipset that would drop straight in to where the existing one is AND had the skills to desolder and resolder AND could hack the firmware of the Mini to accept the new chipset AND rewrote the driver to get it recognised .... when you crack open your new Mini you’ll see :-)

For what the Mini is aimed at doing, the ATI 9200 is more than adequate, but I bet in 6-12months time an upgraded Mini will be available that has meatier graphics and CPU, and if/when the G5 PowerBooks come out a G5 Mini would only be a few months behind.  For now Apple can happily sit back watch the Minis roll out and the cash roll in. (They certainly pursuaded me to sell the PC and get a Mini)
