A new leak has added fresh detail to Sony's rumored PS6 handheld, codenamed Project Canis, suggesting the device will lean heavily on upscaling technology. The leak comes from PC hardware outlet GameGPU, which refers to the device as the "PSP 3" in its reporting, though that name appears to be a placeholder rather than anything official.
According to the report, Project Canis is built around a custom 3-nanometer AMD chip featuring six Zen 6 CPU cores, split between four standard Zen 6c cores and two power-saving Zen 6 LP cores. That's paired with 24GB of shared LPDDR5X memory on a 192-bit bus, and strict power limits ranging from 15W to 25W depending on mode. The graphics side uses 16 Compute Units built on the newer RDNA 5 architecture, with support for Dual-Issue FP32 instructions.

In portable mode, the chip reportedly runs at 1.2GHz for 4.91 TFLOPS of compute. Docked, clocks rise to 1.65GHz for a peak of 6.75 TFLOPS. On paper, that puts Project Canis well below the PS5 Pro's 16.7 TFLOPS. But according to the leak, the handheld's real selling point isn't raw hardware, it's PSSR 3.0, Sony's next-generation upscaling and frame generation technology.

Due to the handheld's tight power limits, GameGPU claims games will render internally at just 540p in portable mode before PSSR 3.0 upscales the image to the device's native 1080p display. Given that, GameGPU estimates an effective performance level of 10 to 11 TFLOPS in portable mode and roughly 14 TFLOPS when docked, numbers that would put Project Canis ahead of the base PS5's 10.28 TFLOPS and closing in on the PS5 Pro.
That claim lines up with earlier comments from insider Kepler_L2, who said Project Canis would outperform the Xbox Series S, listed at around 4 TFLOPS, in rasterization, with an even larger gap in ray tracing and path tracing performance. Kepler_L2 also claimed PSSR 3.0 could exceed NVIDIA's DLSS 4.5 in image quality.

GameGPU is targeting a late 2027 launch window for Project Canis, but it's unclear whether that timeline is tied to the PlayStation 6 itself, which some separate rumors suggest could slip well beyond 2027. That said, GameGPU doesn't carry the same track record as more established leakers like Kepler_L2 or Moore's Law Is Dead, so these figures are worth treating with some caution until more sourcing emerges.
