ROG Ally Z1 vs Z1 Extreme - Full Hardware Comparison & Performance Guide
ROG Ally Z1 vs Z1 Extreme - Full Hardware Comparison
The ASUS ROG Ally comes in two versions that look identical but are fundamentally different machines. The Z1 (non-Extreme) is often sold at a lower price, but the performance gap is substantial. Here is what matters.
Spec comparison
| Component | ROG Ally Z1 | ROG Ally Z1 Extreme |
|---|---|---|
| CPU | AMD Ryzen Z1 - 6 cores, 12 threads, Zen4 | AMD Ryzen Z1 Extreme - 8 cores, 16 threads, Zen4 |
| CPU boost | Up to 4.9 GHz | Up to 5.1 GHz |
| GPU | AMD RDNA3 - 4 Compute Units | AMD RDNA3 - 12 Compute Units |
| GPU clock | Up to ~2.5 GHz | Up to ~2.7 GHz |
| RAM | 16 GB LPDDR5-6400 (shared) | 16 GB LPDDR5-6400 (shared) |
| Display | 7-inch 1080p, 120 Hz, VRR (FreeSync Premium) | 7-inch 1080p, 120 Hz, VRR (FreeSync Premium) |
| Battery | 40 Wh | 40 Wh |
| Storage | 512 GB NVMe SSD | 512 GB NVMe SSD |
| TDP range | 9W-30W (same as Z1E) | 9W-30W |
The GPU is where the difference lives: 4 CUs vs 12 CUs. That is not a small gap - it is a 3x difference in shader compute. The Z1 Extreme has three times the GPU cores.
The GPU gap in practice
The Z1's 4 RDNA3 compute units are roughly equivalent to a Steam Deck's GPU (8 RDNA2 CUs, but RDNA3 CUs are wider). In practice:
| TDP | Z1 (4 CU) | Z1 Extreme (12 CU) | Gap |
|---|---|---|---|
| 9W Silent | ~Steam Deck at 8W | Slightly ahead | Narrow |
| 15W Performance | ~Steam Deck at 12W | ~50-70% faster | Wide |
| 25W Turbo | Hard bottlenecked by 4 CUs | ~2-3x faster | Massive |
At low TDP (9-15W): Both chips are power-starved. The gap narrows because neither can feed its full GPU. The Z1 is actually competitive here.
At high TDP (25-30W): The Z1 Extreme pulls far ahead. The Z1's 4 CUs hit a hard ceiling - you can feed them 30W and they simply cannot process more pixels. The Z1E's 12 CUs scale with the extra power.
Resolution strategy by model
Because the Z1 has only 4 CUs, you cannot target 1080p in demanding games the way Z1E owners can:
| Target | Z1 (4 CU) | Z1 Extreme (12 CU) |
|---|---|---|
| Native resolution | 720p for AAA, 1080p for older/light games | 1080p for most games, 900p for heaviest |
| Upscaling | FSR/XeSS Balanced or Performance (aggressive) | FSR/XeSS Quality (light touch) |
| FPS target | 30 FPS in AAA, 60 FPS in light/e-sports | 40-60 FPS in AAA, 60+ FPS in most |
| RSR (driver upscale) | Essential - run 720p, RSR to 1080p | Optional - run 900p, RSR to 1080p |
RSR (Radeon Super Resolution) is the Z1 owner's most useful tool. Set games to 720p, enable RSR in AMD Adrenalin, and the driver upscales to the 1080p panel. It looks slightly softer than native but costs zero performance.
CPU differences matter less
The Z1 has 6 Zen4 cores vs the Z1E's 8. In GPU-bound games (which is most AAA titles on a handheld), this difference is irrelevant - you hit the 4-CU GPU wall long before the CPU becomes the bottleneck. The extra 2 cores help in:
- CPU-heavy simulation games (Cities: Skylines 2, Factorio megabases)
- Strategy titles (Total War, Civilization late-game turns)
- Emulation (RPCS3, Yuzu - these love cores)
- Background tasks while gaming (Discord streaming, OBS)
For the majority of games, the Z1's 6-core Zen4 CPU is perfectly adequate.
Battery life comparison
Both models share the same 40 Wh battery. At the same TDP, battery life is identical. However, the Z1E can deliver more frames at the same power level, so Z1 owners often run at higher TDP to compensate - which drains the battery faster.
| Scenario | Z1 | Z1 Extreme |
|---|---|---|
| Light indie game at 9W | ~4 hours | ~4 hours |
| AAA at 15W (Z1) / 15W (Z1E) | ~2.5 hours, 30 FPS | ~2.5 hours, 45-50 FPS |
| AAA pushed to target 30 FPS | Z1 at 20W: ~1.8 hours | Z1E at 12W: ~3 hours |
The Z1 Extreme can hit 30 FPS in most AAA games at just 10-12W. The Z1 often needs 18-20W for the same target. That means the Z1E actually gets better battery life at the same frame rate despite having more hardware.
Which games run well on the Z1?
The Z1 is not a "bad" chip - it just needs the right games. Here is how major titles stack up:
Runs great (60 FPS at 1080p)
- GTA V (High settings, 60 FPS at 10W)
- Forza Horizon 5 (Low preset + FSR Quality, 55-60 FPS)
- Doom Eternal (Low-Medium, Vulkan, 55-60 FPS)
- Rocket League (Max settings, 60+ FPS)
- Hades / Dead Cells / Hollow Knight (perfect, maxed out, 4+ hour battery)
- Most e-sports titles (Valorant, CS2, Overwatch 2 at Low)
Playable (30 FPS with tuning)
- Elden Ring (720p Medium, 30-40 FPS)
- Spider-Man Remastered (720p FSR Quality Low, ~30-40 FPS)
- Red Dead Redemption 2 (720p FSR Quality Low/Med, 25-35 FPS)
- Baldur's Gate 3 (900p FSR Quality Low, 30 FPS; drops in Act 3)
- God of War (720p FSR Performance, ~30 FPS)
Struggles (sub-30 even with sacrifices)
- Cyberpunk 2077 (720p FSR Balanced Low, 25-35 FPS - borderline)
- Hogwarts Legacy (720p FSR Balanced Low, 23-30 FPS - rough)
- Alan Wake 2 (not recommended - below 25 FPS even at minimal)
- Starfield (720p FSR Performance, ~22-28 FPS - not enjoyable)
Who should buy which?
Buy the Z1 if:
- You play mostly indie games, e-sports, or older AAA (pre-2020)
- You got a significant discount vs the Z1E (at least $100-150 cheaper)
- You are comfortable with 720p + RSR and 30 FPS targets
- Battery life at low TDP matters more than peak performance
Buy the Z1 Extreme if:
- You want to play modern AAA games at 1080p or near-1080p
- You want 40-60 FPS in demanding titles
- You plan to use the Ally as your primary gaming device
- You want headroom for future games (2025 and beyond)
The Z1 is not a bad device - it is a positioned oddly one. ASUS sells it as a cheaper ROG Ally, but the 4-CU GPU makes it closer to a Steam Deck competitor than a Z1E alternative. Set expectations accordingly.
Settings philosophy for Z1 owners
If you own a Z1, here is the mental model:
- Start at 720p. The Z1's 4 CUs were not designed for 1080p gaming in AAA titles. Accept 720p as your baseline and use RSR to clean it up.
- FSR is mandatory. Do not run native resolution in demanding games. FSR Balanced is your default; FSR Performance for the heaviest titles.
- Lock to 30 FPS. The Z1 cannot sustain 60 FPS in AAA. A locked 30 with RTSS looks better than an unstable 35-50.
- Shadows and volumetrics first. These are the two most expensive settings on low-end GPUs. Drop them to Low before touching textures.
- Turbo mode helps, but not as much as you think. The Z1's 4 CUs saturate around 18-20W. Pushing to 30W Turbo adds heat and fan noise with marginal FPS gains - the GPU simply has no more shaders to use.
Drivers and software
Both Z1 and Z1E use the same AMD Adrenalin drivers. The Z1 benefits from:
- AMD Fluid Motion Frames (AFMF): Driver-level frame generation that doubles perceived FPS. Works well on the Z1 for locked-30 games - makes them feel closer to 60. Adds slight input latency.
- Radeon Super Resolution (RSR): Driver-level spatial upscaler. Essential for the Z1 - set games to 720p, RSR to 1080p.
- Radeon Anti-Lag: Reduces input latency. Useful when running AFMF.
The bottom line
| Z1 | Z1 Extreme | |
|---|---|---|
| GPU cores | 4 | 12 |
| AAA resolution target | 720p | 1080p |
| AAA FPS target | 30 | 45-60 |
| Best use case | Indie, e-sports, older AAA, emulation | Modern AAA, primary gaming device |
| Value proposition | Budget handheld, Steam Deck alternative | Higher-end handheld PC gaming |
