Unreleased AMD Zen 6 APU Leak Points to a Major Upgrade for Future Gaming Handhelds
A new AMD engineering sample has appeared in online benchmark results, and it may offer an early look at the kind of processor that could power next-generation gaming handhelds. The unreleased chip reportedly features 6 cores, 12 threads, and 24 GB of LPDDR5 memory, making it a notable step up from the hardware found in today’s popular portable gaming devices.
The mysterious processor is believed to be part of AMD’s rumored Gainsborough family. While AMD has not officially announced the chip, the benchmark listing suggests it could be based on the upcoming Zen 6 architecture. If accurate, this would be one of the first public sightings of a Zen 6-based APU in action.
The engineering sample appears under the part number 100-000001930-12_Y and was tested on an AMD GBR-FF6-SKT validation platform. According to the benchmark entry, the chip was running at 2.4 GHz during testing. It was paired with 24 GB of LPDDR5 memory using four 6 GB SK Hynix modules, with memory speeds reportedly reaching an impressive 9600 MT/s.
That memory configuration alone makes the sample especially interesting for handheld gaming PCs. Current-generation devices such as the Steam Deck use a custom AMD APU with 4 cores and 8 threads based on the older Zen 2 architecture, along with 16 GB of LPDDR5 memory running at 6400 MT/s. Compared to that, this leaked AMD chip could deliver a noticeable improvement in CPU performance, multitasking, bandwidth, and overall gaming responsiveness.
The benchmark listing also points to AMD Family 1Ah, model DCh, which has previously been associated with Zen 6-related hardware. However, it is still unclear what specific type of core design this sample uses. It could feature standard Zen 6 cores, compact Zen 6c cores, or a new low-power design intended for efficient portable devices.
Early graphics-related benchmarks were also recorded on Ubuntu 24.04 at a 1024 x 768 resolution. The chip reportedly scored 3,871 points in GiMark, 3,508 points in FurMark, and 9,319 points in TessMark. These numbers are interesting, but they should not be treated as final performance indicators. Engineering samples often run at conservative speeds, use early drivers, and may not reflect the performance of the finished product.
There are still several important details missing. The listing does not confirm the chip’s power limits, cooling setup, final GPU configuration, or whether this APU is directly connected to a future Steam Deck model or another handheld gaming device. Even so, the combination of 6 cores, 12 threads, faster LPDDR5 memory, and a possible Zen 6 foundation suggests AMD is preparing a serious performance jump for compact gaming systems.
If this processor or a similar version ends up inside a next-generation Steam Deck or another portable gaming PC, it could bring smoother gameplay, better frame rates, faster loading, improved emulation performance, and stronger efficiency. For handheld gamers, this leak is an exciting early sign that the next wave of AMD-powered devices may offer a much bigger upgrade than expected.
