Single-core scores describe one thread; multicore scores describe aggregate CPU throughput. These results do not establish which CPU is faster in every application. Compare platform support and total upgrade cost before buying.
Intel Atom C5315 lists FCBGA2106; Intel Xeon E5-2637 @ 3.00GHz lists FCLGA2011. Check the motherboard manufacturer's CPU support list and BIOS requirements. If the required platform changes, include motherboard, memory and cooling costs; the CPU price alone is not the full upgrade cost.

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.
