eGPUs are not the solution. Benchmarks aside, they never delivered in terms of application performance.
Apple has a long road ahead convincing developers to fully re-architect their products so they could release their own discrete GPU options which would work better in the short term. Of course if they do this, there’s less of an incentive for devs to move to UMA.

InspiredCode said:I’m still curious about the supply chain rumor that Apple had a discrete GPU in the works code named Lifuka in addition to what we now know as the M1 (Tonga), M1 Pro (Jade C-Chop), and M1 Max/Ultra (Jade C-Die) cores. The other chips were real products, so this must be one last surprise. Could it be a GPU for a Pro Display XDR 2 that uses on display processing to get around Thunderbolt 4 bandwidth limits? Could it be a Mac Pro add on card for ray tracing acceleration? A companion chip for an XR headset or handheld game console? Multiple of these things?
It is also strange that the Max has an extra disabled 16-core neural engine and the Ultra has extra 32-core neural engine. The extra neural engines are only disabled in software. They don’t seem to be used for binning. Maybe a secret feature Apple will turn on later? In theory it could be used for real-time raytracing. The matrix math is similar to ML. Maybe will be introduced in an upcoming release of Metal for immediate use?Unfortunately Apple haven’t even managed to engage the AMXs in Embree (Cinebench/Blender CPU) via Accelerate so baby steps.

And more importantly, it’s great to see apple doing such a consistently wonderful job of advancing the Mac platform. If apple maintains this momentum I think they can gain some serious market share
