No shit. RAM-pocalypse and all that.
But IMO its not just the AI shitfest. Its the choice of hardware as well. If they aimed just 6 months later, they could be using the new Strix Halo SKU instead of garbage bin laptop parts from 2023.
Strix Halo? $2000 Steam Machine you nuts? Actually no. AMD saw pressures from Panther Lake coming, so they lined up cheaper Strix Halos for 2026: AI Max 388 (8x CPU, 40 CU GPU) and 392 (12x CPU, 40 CU GPU). Of the two, 388 would have been perfect for Steam Macine: Single CPU chiplet plus the I/O-GPU chiplet making it much cheaper than 3 chiplet AI Max+ 395.
Cost wise, think about these factors:
- Die size for 7540U (178mm²) and RX 7600M (204mm²) is bigger combined than AI Max 388 (379mm²).
- Dual chip and dual RAM type motherboard complexity vs single SoC and unified RAM pool (Valve engineers talked extensively about mobo layer complexity to accommodate GDDR6 on Gamers Nexus interview).
- Cooling needs are less costly (140W combined vs 120W). The cooling rig on Steam Machine is crazy with giant heat sink and crazy heat pipes for 2 separate chips. The overall box size could have been smaller to boot.
- PSU could shrink from 300W to 230W (GMKtec AI MAX 395 mini PC).
Even if all those factors even out with newer and more expensive SoC vs goodwill AMD laptop parts, the performance gains you get for similar price point is crazy:
- 7540U gets 2250 single thread and 8000 multi thread on Geekbench 6 while 388 gets 2500 and 14,000.
- RX 7600M gets 11,000 on Passmark GPU test while 8060S in 388 gets 18,000.
- 16GB DDR5 5400 gets you about 80ish GB/s, 8 GB of GDDR6 for 7600M gets you around 256GB/s, while 388 gets you 32GB of 256GB/s LPDDR5X.
- 24GB of RAM for Steam Machine makes Valve juggle 2 SO-DIMM slots and 2 GDDR6 chips soldered on mobo while you only have 4 soldered LPDDR5X 8000 chips on 388 mobo for 32GB.
If I was Valve, I would be kicking myself in the ass for rushing the Steam Machine by mere 6 months...
