The retrieval date records when Find Me a CPU collected the source data. It is not a benchmark test date. Prices are USD estimates from the source, converted for other currencies, rather than live retailer offers. Release / first seen means the CPU first appeared on PassMark charts, not necessarily its launch date.
Benchmark scores do not predict frame rates in a particular game. Typical TDP is a specification, not measured electricity use. A matching socket does not confirm motherboard support; check the manufacturer's CPU support list and BIOS requirements.
