That's pretty impressive you spent the time to read the registers from an obscure chipset.

Does the benchmark use all 4 CPUs in parallel?

That Cirrus Logic GD5424 can't even do a blit!

I suspect I added the 450GX in the days when I was pining for a Quad Pentium Pro system, but I never got one, however I have Quad P-II Xeon (Drake) + Quad Xeon MP 7140M DC (Tulsa) + Quad Xeon MP X7460 XC (Dunnington) + Xeon E7-4880 v2 (Ivy Bridge-EX) !

No, it does them one CPU at a time, I suspect a CPU Load of 100% will move from CPU-0 through to CPU-3. I made [Memory Areas] run one thread per NUMA node as it was taking too long on my Ivy Bridge-EX system.

I see the GD5424 is an ISA GPU and was pleased SIV reported it at all. Were it my system I would install a PCI Matrox G450, I have them in my Dual P-III so the drivers work on MP systems, and as there would be 24/32 bit colour SIV would look way better.
