Dependent on both DRAM and cache performance, the results we get from 7-Zip are strikingly similar to what we saw in Visual Studio on the previous page. The $2400 PC’s extra shared L3 still can’t make up for its higher price though, when Paul's $800 PC sells for one-third as much and is half as fast.
WinRAR is notorious for scaling based on architecture and clock rate, giving the least-expensive setup a pronounced value advantage (even if it's the slowest contender). WinZip scaling is even tighter, crushing any hopes that my $2400 PC might achieve value parity.
