Waiting for Bruce Dawson aka randomascii's sequel to "24-core CPU and I can't move my mouse", with "96-core CPU and time has been stilled", with event tracing and flame graphs that show which of those cores are slowing down something basic in Windows.
It's a bit weird (but cool!) that AMD seems to expect to use this chip on ordinary workstations rather than HPC clusters. Hopefully a few of those workstations are bought by the kernel and application developers (who have reasonably parallel workloads like compiling operating systems), otherwise you're likely to have more than an order of magnitude more cores than the average person designing your operating system. Usually, the problem is the opposite - the devs are on new flagship workstation-class devices, and the users on little edge devices (sometimes still with HDDs instead of SSDs!) have a poor experience, but this is kind of the opposite.
- smolder 3y ago> the devs are on new flagship workstation-class devices, and the users on little edge devices This will continue to be true, I think. The vast majority of people buying threadripper machines at threadripper prices are those with serious work to do on them, like compiling huge codebases, hosting piles of VMs, running simulations, or doing certain creative work. I doubt anyone developing 'serious' software that their customers buy 96 core machines to run wouldn't also run similarly powerful machines. There are some tech fetishists who will buy this premium hardware and underutilize it, but not too many.
