Comment I think Walmart's specs are not quite right (Score 4, Informative) 200
"I found the real answer—the normally 2.5GHz chip is underclocked to an anemic 1.5GHz."
"I reached out to AMD to inquire whether this was a standard, supported configuration for the CPU—my AMD rep declined to comment initially and suggested reaching out to Walmart PR instead."
I feel bad for Ars' rep giving them the runaround like this, but I'd give it even odds they thought the answer was obvious enough and expected Walmart to break the news: As other sites that list Evoo EV-C-116-5-* with specs indicate, such as Walmart's own page for an item shipped and sold by VIPOUTLET, the processor is actually an A4-9120e which is a version with 1.5GHz base clock and maximum turbo 2.2GHz.
Also the A4-9120 (with no suffix letter) processor only turbos to 2.5GHz, its base clock is 2.2GHz.
