The GPU in the PS5 is AMDs Radeon RDNA 2, which has variable frequencies up to 2.23GHz, along with 10.3TFLOPs and hardware-accelerated ray tracing. The closest non-off-the-shelf graphics card to the PS5 GPU is an AMD Radeon RX 5700 XT, with a throughput of 9.75 TFLOPs. The closest equivalent graphics card to the PlayStation 5 that comes from AMD is the Radeon RX 5700 XT, which offers 9.8 TFLOPs — a bit lower than the real-world performance of the PS5. In terms of stability in performance, the closest equivalent GPUs to PlayStation 5 will be a Radeon RX 5600 XT, and a Nvidia Geforce RTX 2070 Super.
How the compute and graphics performance of PlayStation 5 GPU stack up against the GPUs used on gaming PCs. The PS5 GPU will be equal and marginally better than an RX5700 XT or an RTX 2070 Super, if we are comparing it with todays GPU line-ups from AMD and Nvidia. Sonys PS5 has a formidable GPU for gaming, meaning that it would deliver better performance. If you already have a decent PC, upgrading the GPU to the RTX 2070 will provide a similar gameplay experience as that of PS5.
The AMD Radeon RX 5700 XT and the Nvidia RTX 2070 Super are both excellent alternatives for a GPU on the PS5, and although both these cards put up a solid fight, you are going to need better hardware in order to get an ideal PC gaming experience at 4K. The PlayStation 5 comes with AMDs RDNA 2 GPU architecture, which is on par with a RX5700 XT, if not higher. The PlayStation 5 has their graphics cards. The PlayStation 5 will have an custom eight-core AMD Zen 2 CPU, which runs at 3.5GHz (variable frequencies), and a custom graphics processor, which is based on AMDs RDNA 2 architecture hardware, which promises 10.28 TeraFLOPS and 36 compute units, which runs at 2.23GHz (also variable frequencies).
As far as what graphics card is in the PlayStation 5: The PS5 houses a custom-built AMD Radeon RDNA 2 GPU. AMD manufactured GPUs are likely the closest graphics cards that I can recommend to be capable of matching the performance of the PS5.
Considering that the PS5 offers 4K performance, the GPU is pretty powerful, producing a whopping 10.3 Teraflops at clock speeds of up to 2.23GHz. Now, looking at those specs, you will realise that the GPU inside PS5 is much more akin to the RX 5700 XT from AMD, and this is no bad thing. Both consoles feature the same GPU; however, PlayStation 5 offers 10 Telops of compute horsepower, which is 6 Telops more than Xbox Series 4s Telops compute horsepower capabilities.
