x86 isn't the only game in town. |
13 |
|
14 |
There's also the raptorcs OpenPOWER systems which is the only new high |
15 |
performance hardware that is owner controlled, has foss firmware and no |
16 |
PSP/ME DRM. |
17 |
|
18 |
The new amd x86 are just as problematic due to having the PSP (AMD's ME) |
19 |
and all the problems that come with that. |

I don't include RISC-V since it is just as expensive as OpenPOWER for |
22 |
much less features and performance and it currently doesn't have an IOMMU. |
23 |
|
24 |
For laptops the only decent non-intel IOMMU having option right now is |
25 |
the G505S which has an IOMMU and supports coreboot with open cpu/ram |
26 |
init (note many companies sell shady "open source firmware coreboot" |
27 |
systems that have an entirely blobbed hw init process) Heres to hoping |
28 |
for a POWER or RISC-V+IOMMU laptop! |
29 |
|
30 |
A libre-firmware OpenPOWER Blackbird system is less expensive than a |
31 |
fully pimped libre-firmware KGPE-D16 and is many times faster even with |
32 |
just the base 4 core cpu (4 threads per core :D) and has the IBM version |
33 |
of OpenBMC which is better than the facebook version that was ported to |
34 |
the KCMA-D8/KGPE-D16's less powerful BMC. |
35 |
|
36 |
POWER is also the only high performance general computing CPU that is |
37 |
made in usa so you support jobs that pay a living wage at a fab that |
38 |
isn't messed around with by the PRC. |
39 |
Raptor claims their boards are us made as well although that is a lofty |
40 |
claim claim in the technology sector as the legal standard is "all or |
41 |
virtually all" components and many companies get shady like a certain |
42 |
one that claims their "linux focused" system is "us made" but the only |
43 |
part made here is the metal case. |
44 |
|
45 |
I would say the best and most secure setup would be: |
46 |
OpenPOWER Blackbird workstation |
47 |
KCMA-D8 for VM gaming (POWER only has a few indie games right now not |
48 |
anything commercial) which can max out the latest games in a VM at 1080p |
49 |
with a 4386 cpu and a RX590. |
50 |
G505S laptop for mobile computing running qubes |
51 |
|
52 |
Ideally you wouldn't run any programs on bare metal and everything would |
53 |
be done in a VM which is what I do even for gaming, watching movies etc. |
