Quote from: DF on April 06, 2024, 14:40:18TB5 is a game changer.
Not at all, it is only 2 times faster than the obsolete pci-e 3.0 x4.
The eGPU requires an optical channel of at least pci-e 4.0 x16 (32GB/s=256GBit/s), which is 4xTB5 ports in aggregation mode.
The funny thing is that Zen4 has 28 pci-e 5.0 lanes, of which 20 are available. Each line 5.0 x1 = TB4. Or 5.0 x2 = TB5.
So last year's 7945HX could easily support a 4xTB5 port matrix, but no manufacturer has done so even at the 4xUSB40 (pci-e 3.0 x16) level...
