CPU:

The 10875h (eight cores) provides sixteen processing threads (sixteen virtual cores) at 5.1GHz.

RAM:

16GB to 32GB (dual-channel) is sufficient for most users.

For hard-core composers, the Platinum Laptop allows up to 64GB.

OS drive:

Small SSD as OS drive is what we recommend for most clients.

With a SSD, the machine boots quicker, apps open quicker, and navigating the OS is a little more "snappy".

Audio drive:

A conventional HD can sustain over 100 solid/contiguous 24Bit/44.1k tracks of audio.

No need for SSD as Audio drive.

Samples drive:

Disk-streaming sample libraries is where SSD really shines.

2.5" SSDs sustain over 500MB/Sec (three times the speed of a conventional HD).

M.2 SSD:

Disk-streaming sample libraries is where SSD really shines.

M.2 SSDs sustain over 500MB/Sec (three times the speed of a conventional HD).

M.2 PCIe x4 SSDs sustain 3200-3500MB/Sec (six to seven times the speed of a standard SSD).

Thunderbolt:

On the PC, we now have complete "PCIe via Thunderbolt" support.

You must be running an up-to-date install of Win10 and have a motherboard that provides Thunderbolt-3 via USB-C port.

RME, MOTU, Presonus, and UA have full "PCIe via Thunderbolt" drivers actually available.  Others are currently testing.

To use a Thunderbolt audio interface, you'll also need a Thunderbolt-3 (USB-C) to Thunderbolt adapter.

Operating System:

At this point, nearly all major audio software/hardware is working well with Windows 10 x64.

For most users, we now recommend Windows 10 x64 Pro.

"Pro" version has Group Policy Editor (easy to shut down OneDrive, Cortana, etc)... and can fully disable all automatic updates.
