I've posted some of this information in the news item thread but thought it best to put it all together in one chunk. This info might be spread around several topics by a few people but its pretty hard to keep up with the thousands of posts a minute that are being posted about the mac mini. Anyway, I've gone through the entire hardware of both models and have compared them.
Here are my findings:
=========================================================================
The Processor
=========================================================================
IBM PowerPC G4
- Speeds of 1.25(1.33) or 1.42(1.5)
- 167 Mhz Bus Speed
- First G4 system with 1.25Ghz CPU and a 167 Mhz FSB was released on the 13th of August 2002 in the form of a Powermac (MDD). It was, however, dual processor. The first single 1.25Ghz G4 was released on the 23rd of June 2003 but these were basically equal or downgraded versions to the previous system
- Altivec Enabled
Intel Core Solo/Duo
- Speeds of 1.5 (Solo) or 1.66 (Duo)
- 667 Mhz Bus Speed
- First Core Duo sysem was released only a month ago
- SSE, SSE2, SSE3, XD bit
- Needs to use Rosetta to run non-native apps.
=========================================================================
The Memory
=========================================================================
IBM PowerPC G4
- PC2700 DDR SDRAM
- Maximum of 1GB in one slot
Intel Core Solo/Duo
- PC2-5300 DDR SDRAM
- Maximum of 2GB in two slots
- Probable Dual Channel support
=========================================================================
The Graphics Cards
=========================================================================
ATI Radeon 9200
- DirectX 8.1 compliant
- Uses R200 technology which was used for the 8500-9200 cards
- The 9200 is actually a *slower* version than the 8500 based cards
- The 9200s use a RV280 core
- Have a core speed of 250Mhz
- Memory speed of 200Mhz
- 128 bit memory interface (12.8GB/s)
- AGP8x connection
- Does support hardware T&L (but very very old)
Intel GMA 950
- DirectX 9.0 compliant.
- Have a core speed of 400Mhz
- Memory speed of 667Mhz (The system's DDR-2)
- Pixel Shader 2.0
- Memory bandwidth of 20GB/s if using 8 lane PCIe or 40GB/s if using 16 lane PCIe
- PCIe connection
- Does not support hardware T&L
- Has to share the system's memory.
So the integrated GMA950 system is faster in every way technically but does not include hardware T&L. But the 9200 uses 2nd generation AI T&L. The X1300-X1800 graphics cards all use 5th generation T&L. That's how old it is.
=========================================================================
Other differences & Similarities
=========================================================================
The Intel models have an extra USB port but lack a modem port. The Intel models all include Airport, Bluetooth and Gigabit Ethernet as standard and also come with Front Row and an infra-red remote.
The Intel Mini is available for $599 or $799 while the G4 model was available for $499, $599 or $699.
Same case, same HDs, same Combo and Superdrives.
=========================================================================
Conclusion
=========================================================================
So by looking at the bare facts it seems to me that the Intel model is significantly 'better' than the G4 model. Yes the cost of the base model has gone up by $100 but then the base model now includes bluetooth, airport, gigabit ethernet, frontrow and an infra-red remote as standard. Not to mention a much more powerful CPU, FSB and memory. Yes Rosetta is required for several pro applications but OS X, iLife, iWork and Frontrow are all native. All Apple pro apps will be native very soon leaving Photoshop being the only major stick in the mud. A G4 model with airport express and bluetooth had the same price as the current base model. The top end model is $100 more expensive than the previous top end model but has a vastly more powerful cpu, FSB and memory and also has frontrow, the remote and gigabit ethernet. The integrated graphics is faster in every way technically than the Radeon 9200 and only lacks the 9200's ageing T&L. The drivers for the GMA950 will probably need more optimising as is apparent on the PC benchmarks but this should improve in time and I doubt as it is the GMA950 will be any slower than a 9200. Also bear in mind that the GMA950 was the graphics card in the transition kit development machines and so has been tried and tested for three quarters of a year now versus ATI's few months. I guess the only thing that the G4 Mini seriously beats the Intel Mini is the fact that it has a modem!!
