Very disappointed to hear this. A different decision would have definitely swayed me to buy AMD for my next processor.

- zdkl 9y agoYou do know intel is doing the exact same thing? This isn't a differentiating attribute.
- samtoday 9y agoWell, you can get a POWER{8,9} workstation [1]; which has a big selling point of having no ME/PSP processor. But it looks a bit expensive. [1] http://raptorcs.com/TALOSII/prerelease.php http://raptorcs.com/TALOSII/prerelease.php
- wolfgke 9y agoI don't know the plans with TALOS II, but those who are interested in what happened to the original Talos Secure Workstation crowdfunding might be interested in the following article, which I think anybody, who is interested in how an alternative could look like, should read: > https://www.crowdsupply.com/raptor-computing-systems/talos-secure-workstation/updates/the-state-of-owner-controlled-computing-as-talos-winds-down https://www.crowdsupply.com/raptor-computing-systems/talos-s...
- rnhmjoj 9y agoWasn't the funding for Talos unsuccessful? Are they really going to release it?
- em3rgent0rdr 9y agoYou can also use C201 arm Chromebook with libreboot (I do) to avoid concerns about a management engine.
- mrec 9y agoIf might have been if AMD were opening up and Intel weren't. EDIT to expand a bit since some people seem to be missing the point: hypothetically, GP might have preferred Intel on narrow technical criteria, but have been willing to override that preference for the sake of transparency. No transparency difference, no reason to override.
- zdkl 9y agoWell in this line of thought at least now there's a chance competition will set either/both on that path. Fwiw I'm not ready to use open-ish ARM/POWER exclusively, but AMD/Intel'll have to contend with that soon(tm) [Answer to parents EDIT] I'd argue the effective technical difference set between AMD & Intel is growing ever narrower, and aside from brand fidelity there is very little reason for a consumer to have non-moral preferences to one or the other manufacturer.
- bo1024 9y agoYes thank you, that's about how I have been thinking about it.

- bo1024 9y agoSorry, I'm confused by your response. I was saying that if AMD took a different approach from Intel, it would have been a differentiating attribute and I would have been swayed in that direction.
- prodmerc 9y agoSo you're going with some open source ARM design then? Because Intel's ME/AMT sure as hell isn't any better.
- cyphar 9y agoARM has TrustZone. OpenPOWER or RISC-V are the only real options at the moment, and both of them are prohibitively expensive to get hardware for and basically require using a softcore in an FPGA.
- simias 9y agoAnd event then you have to trust the closed source synthesis tools on top of the FPGA itself... Of course it would be harder to backdoor but it's probably doable, especially if it targets those particular designs specifically. There's simply no way to get a completely trusted computer stack nowadays, short of assembling it by hand using discrete electronics. It won't run very fast though... I guess an alternative would be to crowdfund the production of an open source CPU then take a few samples and send them to people with an electron microscope and a lot of patience to make sure that the silicon really matches the design and wasn't tempered with in the fab.
- pedroaraujo 9y agoTrustZone is an addon that can be used to implement actual security features into a certain device. It is not attached to ARM's CPUs, not it is mandatory, it is just something that SoC developers can pick up and implement however they want.
- cyphar 9y agoAre there examples of non-TrustZone ARM SoCs? I'm not aware of any, which would make it a moot point about whether a theoretical vendor could make the decision to not includ eit.
