Among the cheapest dual-cores available from AMD and Intel, which is best in regards to encryption performance? Would a Core 2 be a lot better at encryption - enough to justify spending $100 more for one over the cheapest AMD AM2 dual-core? I'm not looking to spend much money; just enough so that my CPU doesn't hold up my backup jobs.
I plan on building a new computer as a home file server running Windows. With it, I plan on using an eSATA drive to backup my data to a drive with a TrueCrypt 5.0a encrypted NTFS partition. The data will also be compressed. I'm not as concerned about encrypting the system drive.
The build will only be a simple file server with just a bunch of drives and file shares. No RAID and off-the-shelf hard drives. However, I will also want to be able to run a virtual machine or two on it, so hardware virtualization support is a plus.
Which CPU should I pick for this build? If it was merely a file server, then it really wouldn't matter too much. However, encryption really slows my backup jobs - an AMD Sempron 2800+ tops out about 40MB/sec with Twofish encryption - which is hardly fast enough to keep up with a hard drive (that number doesn't take into account compression either). I'm looking to backup more than 300GBs.
Of course, if you can't answer my question I'd appreciate it if you could post your TrueCrypt benchmarks so I have a better idea of what I should look for.
Thanks in advance!
