How many teraflops does the original PlayStation 4's GPU deliver?

The original PlayStation 4’s GPU delivers a theoretical peak of 1.84 TFLOPS.

Its graphics processor is based on AMD’s Graphics Core Next architecture and contains 18 compute units running at 800 MHz. Together, those units provide 1,152 stream processors and a theoretical single-precision performance of about 1.84 trillion floating-point operations per second.

TFLOPS is a measure of arithmetic throughput, not a direct guarantee of visual quality or game performance. Resolution, memory bandwidth, software optimisation, architecture, and a game’s rendering techniques all affect what players see. The PS4 combines its GPU with 8 GB of GDDR5 memory, providing 176 GB/s of memory bandwidth.

The main trap is confusing the original PS4 with the PS4 Pro. The Pro increased its GPU to 36 compute units at 911 MHz, producing about 4.2 TFLOPS. Meanwhile, the 10.28-TFLOPS figure belongs to the base PlayStation 5, not the PS4. Thus, 1.84 TFLOPS is the appropriate canonical answer for the original PS4’s GPU.
