The headline is deliberately punchy. The point underneath it holds up, but it needs some qualifiers. Here's what the published specs support, and where the argument goes too far.
The Steam Deck's GPU: built for 15 watts, not for spec sheets
Valve's own spec page for the Steam Deck OLED lists:
- APU: custom 6 nm AMD chip
- CPU: Zen 2, 4 cores/8 threads, 2.4–3.5 GHz
- GPU: 8 RDNA 2 compute units at up to 1.6 GHz, rated at 1.6 TFLOPS FP32
- APU power range: 4–15 W
- Memory: 16 GB LPDDR5 at 6400 MT/s across quad 32-bit channels
- Battery: 50 Wh, which Valve rates at 3–12 hours of gameplay
Butler is right that the OLED refresh didn't change the GPU. It brought a 7.4-inch, 1280 × 800 HDR OLED panel at up to 90 Hz, a bigger battery and other refinements, but the graphics are the same 8-CU RDNA 2 design. In practice, the "new" Deck is the old Deck with a much better screen.
He also gives Valve some credit. He notes that pricier, newer handhelds beat the Deck on GPU power, but the Deck can keep up with or even beat them when everything is held to the 15 W-or-lower range you need for decent battery life. That's the trade Valve made in 2022: performance per watt over peak performance.
Section summary: The Deck's GPU is a low-power 2022 design that Valve never replaced. "Outdated" fits for demanding new games. "Obsolete" overstates it for the device's battery-limited job.
Meet the NucBox K12: the mini PC in the comparison
Butler's example comes from a TechRadar review by Alastair Jennings. TechRadar lists the K12 with:
- CPU: AMD Ryzen 7 H 255, 8 cores/16 threads, Zen 4. One line of the review says "H 225," but the spec table and features section both say H 255.
- Graphics: AMD Radeon 780M (RDNA 3)
- Memory: 32 GB DDR5-5600 SO-DIMM, dual channel, up to 128 GB
- Storage: 1 TB PCIe 4.0 NVMe, plus two more M.2 2280 slots
- Ports: USB4, OCuLink (PCIe 4.0 ×4), HDMI 2.1, DisplayPort 1.4, dual 2.5G Ethernet
- OS: Windows 11 Pro preinstalled
The Radeon 780M is no secret. AMD announced the Radeon 780M and 760M during CES 2023 as major attractions of the Ryzen 7040 series Phoenix family APUs, and the chip has 12 CUs (768 SPs). CPU Monkey's database notes that AMD has been using it since 2023 in the Phoenix and Hawk Point APUs, for example in the Ryzen 7 7840HS, Ryzen 7 8845HS, Ryzen 9 7940HS and Ryzen 7 7840U for notebooks and in the Ryzen 7 8700G desktop APU. That matches Butler's point that a 2023 GPU is now common enough to turn up in budget mini PCs.
Is the 780M really "nearly twice" the Deck's GPU?
Butler says the 780M offers "nearly twice the raw performance" of the Deck's GPU. That figure is a rough estimate, and the paper specs actually suggest a bigger gap:
| Spec | Steam Deck (Aerith) | Radeon 780M |
|---|---|---|
| Architecture | RDNA 2 | RDNA 3 |
| Compute units | 8 | 12 |
| Peak GPU clock | 1.6 GHz | ~2.9 GHz (varies by device) |
| FP32 (official/typical figure) | 1.6 TFLOPS (Valve) | ~4.5 TFLOPS, up to ~8.9 with dual-issue |
The 780M's TFLOPS figure comes with an asterisk. CPU Monkey gives a theoretical computing power of around 4.5 TFLOPS (FP32), and thanks to the dual-issue capability of RDNA 3 even about twice as much in favorable cases. Other databases simply list the larger number. One cites FP32 Performance 8.9 TFLOPS. Games rarely reach those best-case dual-issue gains, which is why TFLOPS comparisons across GPU generations are shaky.
Clock speeds aren't fixed either. Reviewers point out that actual sustained clocks vary heavily by device power limit, chassis cooling, memory configuration, and firmware tuning. A 780M in a well-cooled, mains-powered mini PC behaves very differently from one held to handheld power limits.
Memory bandwidth complicates things
Integrated GPUs don't have their own VRAM; they share system memory. CPU Monkey stresses that fast LPDDR5X or DDR5 memory in dual-channel mode is very important for full performance.
Here's a simple calculation from the two published memory specs (our own arithmetic, not a benchmark):
- Steam Deck OLED: 4 × 32-bit channels at 6400 MT/s ≈ 102 GB/s theoretical peak
- NucBox K12 as reviewed: dual-channel DDR5-5600 (128-bit) ≈ 90 GB/s theoretical peak
So on paper, the K12 has less memory bandwidth than the Deck, even though its GPU has far more compute. That's one reason the 780M's real gaming lead is smaller than the TFLOPS figures suggest. It also cuts against Butler's suggestion that the K12's extra RAM roughly evens out the price comparison. Capacity isn't the same thing as bandwidth.
Section summary: The 780M is clearly the more capable GPU on paper. But "nearly twice" is an estimate, not a measured, game-by-game result, and nobody has published a controlled K12-versus-Deck test at matched settings.
What the K12 actually does in games
TechRadar's testing is the best evidence available. The review found the 780M handled DiRT Rally and Tekken 8 fine, but Indiana Jones and the Great Circle and Hogwarts Legacy needed lower graphics and resolution settings. Its synthetic results included a 3DMark Time Spy graphics score of 2,796 and a Fire Strike graphics score of 8,171.
That Time Spy score fits with other reports. Early leaked figures put a 780M with DDR5-5600 at ~2750 in Time Spy graphics, compared with an average of 2,383 for the older RDNA 2-based Radeon 680M.
TechRadar lists "limited GPU capability" as a downside and recommends the OCuLink port and an external GPU for anyone who wants serious gaming. That's an odd fit for a machine held up as proof that integrated graphics have arrived. The fairer reading: the K12 is a capable 1080p-low-to-medium machine. It's well beyond the Deck, but not a gaming rig.
The price argument is a moving target
Butler says the K12 cost about $550 for 32 GB when TechRadar reviewed it, and that the 32 GB/512 GB model now costs about $880. He says that's close to the price of a 512 GB Steam Deck OLED. TechRadar's review lists the 32 GB/1 TB unit at $549, the 64 GB/1 TB version at $609, and barebones models from $409.
We haven't independently confirmed today's prices for either device. Treat all these figures as snapshots. Butler's complaint that a "cheap" mini PC now means anything under $1,000 tells you more about current memory and component costs than about the K12 itself.
The comparison is useful, but it isn't like for like
Butler admits the mini PC is not a Deck replacement, and the gap is real:
- The K12 needs mains power, a monitor, a keyboard and mouse or a controller, and a desk.
- The Deck includes a screen, a 50 Wh battery, gamepad controls, two haptic trackpads, a gyro and a microSD slot, all in roughly 640 grams.
- The power budgets differ: Valve specifies the Deck's APU at 4–15 W. The K12 is a mini PC with active cooling and a turbo fan button. Without measurements under the same conditions, nobody can claim a fair performance-per-watt comparison.
What the comparison does show is that the floor has risen. An integrated GPU that was premium in 2023 now sits in mid-priced mini PCs, and it beats the Deck's graphics when it isn't held to handheld power limits.
The column also brings in the Nintendo Switch 2. Butler says he sold his Lenovo Legion Go because he kept reaching for the lighter Switch 2, and he credits DLSS and Boost Mode for older games. That's his personal experience, not a hardware finding. Many Deck owners would point to their Steam library, mods and open platform as reasons to stay.
Valve's position on a Steam Deck 2
Valve has been consistent here. In October 2024, PC Gamer reported Valve designer Lawrence Yang saying the company is "not doing the yearly cadence." He said Valve wants to wait for "a generational leap in compute without sacrificing battery life" before releasing a true second-generation Deck.
Butler reads "generational leap" as at least triple the performance at the same wattage. That's his interpretation, not a Valve requirement.
He also cites Digital Foundry reporting on a rumored GPU codenamed "Gainsborough" (Aerith's surname in Final Fantasy VII), said to be a 12-CU RDNA 4 part. We couldn't confirm the chip, its specs or any link to a future Deck, so treat it as rumor. For context, AMD's RDNA 4 desktop GPUs launched February 28, 2025, so the architecture itself exists.
Butler's most useful design point is that a Steam Deck 2 needs a much bigger performance gap between battery and plugged-in use, the way the Switch 2 speeds up when docked. The K12 shows how much the 780M can do with wall power and good cooling. A successor that scales up when docked could serve both kinds of players.
Bottom line for PC gamers
- If you own a Deck: It's still good for indie games, older AAA games and anything Deck Verified at modest settings. Newer, heavier games will need low settings or won't be playable.
- If you want a cheap desk-bound gaming PC: A 780M mini PC is a reasonable 1080p option, and the OCuLink port lets you add an external GPU later. Check memory configuration, because dual-channel RAM matters a lot for integrated graphics.
- If you're waiting for a Steam Deck 2: Valve's stated aim is a big generational jump without losing battery life. There's no release date and no confirmed chip yet.
Butler's broader point holds: integrated graphics have moved well past the Deck. "Completely outdated" is still an opinion. The 2022 hardware is showing its age, but for a battery-powered handheld running at 15 watts, its design choices were sensible ones.
