I didn't have much else to do today, so I decided to rig up all my five PPC G4 Macs to see how they compared on Geekbench 2. The baseline is a score of 1000 for the entry level G5 introduced in 2003. I have five G4 rigs, and I just ran them through the motions. I used 2.2.0 on Tiger for all but one of them, because it only has Leopard installed (I used 2.2.7 on that one.) I was curious to see how they would all do. So from high score to low score, here we go: 1. Digital Audio, 1.467 GHz OWC Mercury G4 CPU (upgraded from 667 MHz), Radeon X800 GPU (I think it is a FireGL X3 flashed to X800 for Mac), 256 MB VRAM (with pins 3 and 11 taped to work in this model), 1.5 GB of RAM, with SSD (2001). Score: 838. Would love to see how a dual 1.8 might change the score here, but for now this will do. Also -- it seems like 2 of my three 512MB RAM modules are acting as 100 MHz RAM even though all of them are supposed to be 133 MHz (and I have confirmed it's the RAM, not the slot). I will rerun if I can get all 133 MHz RAM to show up in the System Profiler. This is the one I (until very recently) had horrible problems with heat until I installed a very loud main exhaust fan last week. I ran this test with the side door closed! 2. 12" Aluminum PBG4, 1.33 GHz, 1.25 GB RAM, 64 MB GeForce 5200 Go, 60 GB HDD (2004). Score: 792. This is the only one of these which has not been upgraded with some sort of solid state solution (usually an mSATA drive with 2.5" IDE adapter). This model is not easy to upgrade the storage so I've never bothered. I was actually surprised at how close it came to the performance of the Mac above it. But they both do have a 133 MHz bus and the newest tech built in among the lot. 3. Titanium PBG4, 1 GHz, 1 GB RAM, 250 GB SSD (mSATA to IDE), 64 MB VRAM Mobility Radeon 9000 (2002). Score: 624. Although the Pismo is my favorite Mac ever in terms of engineering (with one exception, see below), this one is my go to portable Mac. It natively supports OS 9 and Leopard and handles all of it very well. Sure, if I ever get a 17" DLSD I might go to that one, but until then.... 4. Power Mac 7600, 1 GHz Sonnet Crescendo G4, 1 GB RAM, PCI Radeon 9200 graphics (128 MB VRAM) with mSATA to IDE SSD through a Sonnet Tempo PCI card (1996). Score: 435. This one was mostly held back by the 50 MHz system bus and the PCI-based GPU (the three above have AGP-based GPUs). This one is about as maxed out as you can get, and it's still marginally usable for most things 21 years later, which is remarkable in and of itself. 5. Powerbook "G3" (Pismo), upgraded with G4/550 card, 1 GB RAM, 8 MB Rage Mobility 128 GPU, mSATA to IDE SSD (2000). Score: 319. I think the graphics clearly held this one back. I love the Pismo even today as much as any Mac ever built, but the terrible GPU that can't be upgraded is a massive bottleneck here. This Mac has a 100 MHz bus compared to 50 MHz to the souped-up 7600 above, but the graphics are like an anchor strapped to its back. That said, for relatively moderate usage and even some web browsing with TFF optimized with the settings described in this forum, it's not horrible.
