The lack of SMT in client won't be significant enough for gaming. Vulkan/DX12 gaming leans more to SMT=Off having the highest FPS.

ARM can lean towards more energy efficiency with aiming for dead/gated units. Rather than completely filled units and thrashed regs/renames/caches/etc.

The real issue will be discrete GPUs. Since, both ARM's and Qualcomm's solutions are laptop leaning. So, it is going to hit that iGPU wall where x86-64 desktop can just slap latest phat dGPU in.

The only case for a successful ARM takeover for PC gaming is not adopting SMT but rather getting into the desktop market. Where CN gets it, Qualcomm/ARM will most likely never get it.

As well as SMT being replaced by BT [Bulk threading]. Ideal solution is >4 Cortex-X prime cores and >8 Cortex-A energy efficient dense option cores.

Where most of the back-end for games are being switched to bulk cores(Cortex A) while the front-end is handled by prime cores(Cortex X).

Getting to the "igp" wall is already good enoght to get a good portion of the market, the next Malis can probably rival RDNA2/3 IGP on the bigger configurations, just do a quick search to see how many systems are sold with less than that.

Its more of a matter of who is going to put the money to make a Windows driver and to provide Windows support as ARM does not seems to be interested.
