Chips and Cheese acquired a Zen 2 CPU used in Sony's PlayStation 5 and went to town studying differences compared to AMD's Ryzen-branded products sporting the same CPU architecture (like the Ryzen 3000 series). The chip review outlet found that Sony's custom-designed Zen 2 chip sports a heavily cut-down FPU that's shrunk by 35%. However, Chips and Cheese discovered these changes don't impact gaming performance making it the "perfect" gaming CPU.
The area AMD paid the most attention to when designing Sony's custom Zen 2 PlayStation 5 CPU was the FPU, or floating point unit. AMD cut down the number of floating point pipes and eliminated some of the FP/vector execution units. Compared to a comparable Zen 2 Ryzen CPU desktop chip like the Ryzen 7 3700X or 3800X, Sony's custom Zen 2 chip comes with only half of the FPU capabilities of a 3700X or 3800X.
