GeForce 6200 for G4 Cube

Originally posted March 24th, 2006, by rob-ART morgan, mad scientist

The CubeOwners are a stubborn bunch. They love their Cube. They snort at the Mac mini. They snear at the iMac. Amazingly there are a lot of upgrades you can make to the original G4 Cube to keep it going forever.

We have a 'naked' Cube on our test bench that we have upgraded with a faster hard drive, maximum memory (1.5GB), and a 'factory second' dual CPU upgrade (one CPU running at 1.4GHz and the other at 1.7GHz). Thanks to a member of the 'experimental graphics card' forum on, we had a chance to test drive the latest graphics card 'darling' of the Cube bunch, a GeForce 6200. We compared it to the original card (GeForce2 MX) and a few other experimental cards that fit inside the Cube case without modification.

Graph Legend:
GeF2 MX - nVIDIA GeForce 2MX (32MB VRAM, original factory card)
GeF 3 -- nVIDIA GeForce 3 (64MB VRAM)
Rad 9000 -- ATI Radeon 9000 (64MB VRAM)
GeF 5500 -- nVIDIA GeForce 5500 (128 bit version modified with FX 5200 code, 256MB VRAM)
GeF 6200 -- nVIDIA GeForce 6200 (modified with GeForce 6600 code, 256MB VRAM)

Believe it or not, there are owners of G4 Cubes who want to run Core Image apps. To do so, you need a card that can do the Core Image processing in place of the main CPU. The only Cube compatible card that supports Core Image properly is the GeForce 6200.


The 'mutant' GeForce 6200
is not only fast on the Cube, but it would appear to be the ideal GPU upgrade -- fits without modification, requires no auxillary power feed, runs cool and quiet, and supports DVI displays.

With no retail GPU options for the G4 Cube owner, it's nice to know some mad scientists on the Strange Dogs forum are giving hope and encouragement.

There is an ethical issue you must deal with when taking the ROM code from a Mac graphics card you DON'T own and flashing it into the ROM of a Windows PC graphics card. And it isn't that simple. Sometimes the ROM code must be modified before it will work in the PC card. Sometimes the ROM itself must be replaced with a bigger one. This really is rocket science. Do it wrong and you will end up with an expensive door stop.

There is a lot of frustration with the dirth of really fast aftermarket graphics cards for the various G4 and G5 Power Macs. And when a truly fast retail card appears, it's often much more costly than the PC equivalent.

We feel Apple Computer has created a lot of frustration by either NOT offering aftermarket upgrades (like the GeForce 7800 GT) -- or -- by offering them at high prices and then pulling them off the market even before the current model goes out of production (like they did with the GeForce 6800 GT and Ultra). These practices have made many consumers feel justified in experimenting with the flashing of PC graphics cards.

I commend ATI Technology for their continued efforts and investment in providing aftermarket, affordable GPUs for the Mac community including the $199 Radeon 9600 PC and Mac Edition, the $299 Radeon 9800 Pro Mac Edition, and the $399 Radeon X800 XT. I hope they will soon release the Radeon X1800 PCIe card that they were demonstrating at MacWorld SF in January 2006. Better yet, make mine an X1900 XT.

Also encouraging was the announcement by XFX Graphics that they have signed a licensing agreement with Apple to develop and bring to market a range of NVIDIA GeForce-based Shader Model 3.0 graphics accelerators to for AGP Power Macs. The initial offering in June 2006 will be a GeForce 6600 GT, though more powerful, higher-end variants are planned.
