One of our anonymous sources managed to run Leopard on atom based system he got.
Atom cpu has ssse3 and 64-bit, so it runs unmodified osx leopard kernel with efi emulator.
Detailed specs is:
CPU : Atom 1.6 Ghz
sound chip: ALC662
512 MB RAM
osx missdetects cpu cache size, but it’s only cosmetic, not performance hits because of it
Here is some screenshots of tests which shows atom performance with osx.
geekbench 1.0 32-bit – 84.7 points
geekbench 1.0 64-bit – 90.8 points
“The machine could perform better with more RAM memory”
So you can see what performance will have atom based apple portable macs.
oh, and btw, this thing could run of a solar panel
here some techincal info from system:
hw.ncpu = 2
hw.cpufrequency = 1600000000
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON DSCPL TM2 SSSE3 CX16 TPR PDCM
machdep.cpu.brand_string: Intel(R) Atom(TM) CPU 230 @ 1.60GHz
so it looks like Atom uses hyperthreading.
