Incredible PS5 Pro ray tracing performance leaks with up to 400% uplift vs PS5 alongside details of custom DLSS rival

Sony is rumored to release the PS5 Pro later this year, potentially in September, with a big performance improvement over the base PS5. So far, leaks have alleged that the PS5 Pro features an 8-core Zen 2 CPU, up to a 30 WGP (60 CU) GPU, 16 GB of memory running at 18 Gbps, and a 256-bit wide memory bus. 

Moore’s Law Is Dead (MLID) has now published a new PS5 Pro leak video that reveals incredible details about the GPU, machine learning, and Sony’s custom upscaling tech.

PS5 Pro GPU with up to 4x faster ray tracing

MLID presents a document in the video which lists “Higher GPU performance” as one of the three main selling points of the PS5 Pro (codenamed “Trinity”). The PS5 Pro’s GPU is allegedly “larger” and brings a 45% boost in performance over the standard PS5. While this proposed performance increase is sizeable, it is quite a bit less than a previous report which put the number at 50-60%.

Furthermore, MLID reports that the PS5 Pro GPU is anywhere from 2 to 4 times better at ray tracing than the base PS5 (Available on Amazon). This is in line with a leak from December 2023 which alleged more than 2x the improvement. Interestingly, if the PS5 Pro has ray tracing that is more than two times as fast as the regular PS5, the PS5 Pro might not have a simple RDNA 3 or 3.5 GPU as has been leaked.

Consider this, the RX 7900 XTX, the fastest RDNA 3 GPU on the market, is only 36% faster than the RDNA 2-based RX 6900 XT per TechPowerUP’s testing of RT at 4K. Since the PS5 features an RDNA 2 GPU, the purported PS5 Pro with an RDNA 3 board would bring nowhere near the performance of the leaked numbers unless it is packing some RT improvements not seen on regular RDNA 3 cards. This could exactly be the case as a past rumor suggested that the PS5 Pro’s GPU packs some RT tech from RDNA 4.

Moving on, MLID also reports that the console’s GPU boasts 300 TOPs of 8-bit Integer machine learning and 67 TFLOPs of 16-bit or 33.5 TFLOPs of 32-bit Floating Point performance. As a reference, the base PS5 and Xbox Series X (Buy it on Amazon) are rated for 10.28 and 12 TFLOPs respectively.

PlayStation Spectral Super Resolution (PSSR)

The PS5 Pro is rumored to employ a custom DLSS-like tech for upscaling. MLID suggests that the tech is called “PlayStation Spectral Super Resolution” and is a “Temporal Anti-aliasing Upscale” that is accelerated with machine learning. The upscaler supports a maximum resolution of 4K with support for higher resolutions reportedly on the cards for future versions.

Per the document obtained by MLID, PSSR is very similar to DLSS and FSR in its input requirements, supports full HDR, and works with dynamic resolution. Moreover, the upscaler apparently doesn’t require training on a per-game basis matching DLSS.

When it comes to resource requirements, PSSR supposedly needs 250 MB of memory and 2 ms to upscale a 1080p input to 4K. However, this running time can change in the future as optimizations are underway.

Long story short, GPU performance and upscaling could be the killer weapons of the PS5 Pro. This could allow Sony to market the console as a 4K beast that can not only do incredible ray tracing but also do it at high frame rates.

While all of it sounds amazing and we are definitely excited to know more, it is important to take the information with a grain of salt.
