The other thing to keep in mind is that most of the benchmarks you see on the internet for these older systems haven't been redone with the mitigations needed for the new speculative execution vulnerabilities, but the ones for the newer processors more likely have, so you're not comparing like with like. A cheap eight core processor sounds great until it turns out to be slower at everything than an even cheaper modern quad core. A quad core Ryzen 3 is under a hundred bucks, with a 45W TDP instead of 130W.
