KeplerL2: Sony handheld GPU is ahead of Xbox Series S
Sony’s rumored next-generation handheld may launch before Steam Deck 2, according to new comments from leaker KeplerL2. The leaker, known for revealing many Sony secrets, also claims the device’s GPU is slightly ahead of Xbox Series S in raster performance, and much further ahead in ray tracing and path tracing. None of this is official, so the claims should still be treated as rumor.
According to earlier leaks the rumored PlayStation handheld is powered by AMD chip with four Zen 6c cores, two Zen 6 low-power cores, 16 RDNA 5 compute units, and 24GB of LPDDR5X memory on a 192-bit bus. KeplerL2 did not comment on the specs, but on performance target.

FSR 5 & PSSR3 ahead in image quality
In the same thread, Kepler said Switch 2 uses DLSS 2 and that some games rely on a lighter implementation, then added that a future FSR 5 or PSSR 3 solution could deliver better image quality than current DLSS 4.5. The name of Sony’s new upscaling tech is, of course, just speculation, in fact, Sony doesn’t even use the PSSR2 name for the enhanced variant now used by PS5 Pro.

When asked whether Valve’s next handheld would be ready by the time Sony’s device launches, KeplerL2 answered “Nope.” In another comment, the leaker added that Valve had been targeting 2028, but that current RAM and NAND conditions could push the schedule back.
For now, there is no official word from Sony or Valve.
