That's one slow phone, go to Geekbench, and it gets around 800 for single core performance. Walmart's site doesn't say what CPU it has, Geekbench does, "ARM MT6763V/B".
It's a Mediatek CPU, according to this, the speed is 2000 MHz, but Geekbench says 1500 MHz. CPU is from 2017.
My iPhone 7 gets 3520 for the single core score. The reason, I never need a new phone. Except, the battery won't hold a charge forever. And it doesn't have 5G, or 10G.
