64 정도인듯....

1.Intel x86:
Maximum CPUs: 32 (including logical CPUs)
Maximum memory: 64GB
Maximum filesize: 8TB
Maximum filesystem size (ext3) 16TB
Maximum per-process virtual address space: 4GB

2.AMD64/EM64T:
Maximum CPUs: 64
Maximum memory: 128GB
Maximum filesize: 8TB
Maximum filesystem size (ext3): 16TB
Maximum per-process virtual address space: N/A

These are standard max limitations whereas Linux cluster systems can scale up to 1024 CPU's.
That is 32 or 64 CPUs for x86 and x86_64 respectively.

Redhat says the same, but in a management-friendly table. Redhat EL6 can do 32 for x86, or 128 or 4096 CPUs cores for x86_64.

arch/x86/Kconfig says these CONFIG_NR_CPUS limits can be raised if CONFIG_MAXSMP is enabled. – ephemient Dec 3 '10 at 18:30

그..그렇군요 ㅠㅠ

The x86_64 Linux kernel can handle a maximum of 4096 Processor threads in a single system image. This means that with hyper threading enabled, the maximum number of processor cores is 2048. Yes there is computers with more than 2048 processor cores; but these runs as clusters where several Linux kernels cooperate, connected with a high speed interconnect, typically an Infiniband fabric.
