If you've been keeping up with the Windows gaming handheld world, then you're likely very aware of the AMD Ryzen Z1 line of gaming handheld APUs (accelerated processing units).
But we're now at the point where AMD has been slowly releasing its next-gen Ryzen Z2 line of chips in next-gen gaming handhelds.
Between official announcements and leaks, we've learned that the Z2 Series of handheld chips is comprised of at least five processors. Here's how they compare and what we know about them so far.
UPDATE June 8, 2025: AMD officially revealed the new Ryzen Z2 and Ryzen AI Z2 Extreme APUs. I've added their details to this page.
Chip | CPU Cores & Threads | Graphics | TDP |
Ryzen AI Z2 Extreme | 8 cores, 16 threads w/ XDNA2 NPU (Zen 5) | 16 GPU Cores (RDNA3.5) | 15-35W |
Ryzen Z2 Extreme | 8 cores, 16 threads (Zen 5) | 16 GPU Cores (RDNA3.5) | 15-35W |
Ryzen Z2 | 8 cores, 16 threads (Zen 4) | 12 GPU Cores (RDNA3) | 15-30W |
Ryzen Z1 Extreme | 8 cores, 16 threads (Zen 4) | 12 GPU Cores (RDNA3) | 15-30W |
Ryzen Z2 Go | 4 cores, 8 threads (Zen 3+) | 12 GPU Cores (RDNA2) | 15-30W |
Ryzen Z2 A | 4 cores, 8 threads (Zen 2) | 8 GPU Cores (RDNA2) | 6-20W |
Ryzen Z1 | 6 cores, 12 threads (Zen 4) | 4 GPU Cores (RDNA3) | 6-15W |
As of right now, AMD has only officially revealed information for five Z2 chips: The Z2 A (used in Xbox Ally), Z2 Go (made exclusively for Lenovo Legion Go S), Z2, Z2 Extreme, and AI Z2 Extreme (seen in Xbox Ally X).
Overall, the AI Z2 Extreme is the most powerful APU of the bunch, capable of handling the graphically straining games better than the other chips in the series.
Since it's an AI processor, the NPU (neural processing unit) can help take some of the load off of the CPU and GPU to help a system run more efficiently as a whole.
As always, any handheld with the AI Z2 Extreme will technically be an AI PC.
Based on details revealed for the AMD Ryzen Z2 A APU, it seems to be a rather modest chip, comparable to the performance of the Steam Deck SoC (thanks PC Gamer).
It also offers certain trade-offs compared to the Z1 chip found in the base configuration of the original ASUS ROG Ally.
More AMD Z2 Series-powered gaming handhelds are expected to launch this year and next year.
We're anticipating the ROG Ally 2 and Legion Go 2 to have Z2 Extreme configurations. But, as of right now, there are no release dates for these handhelds.
AMD Ryzen Z1 and Z2 Series FAQ
How is AMD Z1 Series different from Z2 Series?
The Z2 Series chips are next-gen gaming handheld processors following the first iteration of Z1 Series chips.
Higher-end, Z2 Series chips offer faster CPU speeds, better power efficiency, better graphics, and newer architecture than Z1 Series. In other words, games might run more smoothly and efficiently on a handheld with a higher-end Z2 Series chip.
However, the Z2 Go and Z2 A chips are designed around simpler gaming and aren't as powerful as Z2, Z2 Extreme, or AI Z2 Extreme.
Which AMD Ryzen Z2 chip is best for gaming handhelds?
The Ryzen Z2 Extreme is likely offers the best gaming handheld performance out of the series, but will likely be more expensive than most of the other options. However, it's hard pin down chip performance before all of the AMD Z2 chips come out and we've had a chance to test them. The rumored Ryzen AI Z2 Extreme will likely cost more than the others since AI processors do tend to be more costly.
Which AMD Ryzen Z1 or Z2 Series chip should I get?
We still haven't been able to test many of these chips since they haven't released yet. However, we can easily recommend the Z1 Extreme as a great gaming handheld APU for more intensive handheld gaming. If the next generation truly improves upon the original one, than the AI Z2 Extreme will likely be our top recommended handheld APU. That said, if you simply want a cloud gaming device, you might be better served with a Z1 or Z2.
Which AMD Ryzen Z2 Series chip should I avoid?
Of the Z1 and Z2 chips that have released thus far, the Z2 Go made exclusively for Legion Go devices, is the one that we suggest you avoid. It is costlier than Z1 Extreme, but doesn't offer enough power to keep up with the previous chip generation. Lenovo has stated that the Z2 Go conserves power and helps the battery last longer, but in our own testing, the Z2 Go-powered Legion Go S still had a relatively short battery life like Z1 Extreme handhelds.
Which gaming handhelds have Z2 Series chips?
Lenovo Legion Go S - Z2 Go
Lenovo Legion Go 2 (prototype) - Z2 Extreme
ASUS ROG Ally 2 (rumored) - Z2 Extreme
