Intel Says Some CPU Models Will Never Receive Microcode Updates (bleepingcomputer.com)

An anonymous reader writes: Intel released an update to the Meltdown and Spectre mitigation guide, revealing that it stopped working on mitigations for some processor series. The Meltdown and Spectre mitigation guide is a PDF document that Intel published in February. The file contains information on the status of microcode updates for each of Intel's CPU models released in the past years. Intel has constantly updated the document in the past weeks with new information about processor series and the microcode firmware version number that includes patches for the Meltdown and Spectre flaws.

An update published on Monday includes for the first time a "Stopped" production status. Intel says that processors with a "Stopped" status will not receive microcode updates. The reasons basically vary from "redesigning the CPU micro-architecture is impossible or not worth the effort" to "it's an old CPU" and "customers said they don't need it." The following Intel processor products received a "Stopped" status marker: Bloomfield, Bloomfield Xeon, Clarksfield, Gulftown, Harpertown Xeon C0, Harpertown Xeon E0, Jasper Forest, Penryn/QC, SoFIA 3GR, Wolfdale C0, Wolfdale M0, Wolfdale E0, Wolfdale R0, Wolfdale Xeon C0, Wolfdale Xeon E0, Yorkfield, and Yorkfield Xeon.

This is BS.

I'm sorry, but if I'm investing in a high-end, server-class CPU, I expect it to be supported for as long as is reasonably possible. If they said they weren't updating 10 year old Celerons or Atoms, that might be understandable. But Xeons? Let's just say I don't plan to every buy one again, at least so long as AMD represents a reasonable alternative. In fact, I will always stick with AMD (as I long have, for other reasons) until and unless Intel makes some kind of definite, enforceable support commitment.

The processor of the PC on which I am writing this is just ten years old. Why do you believe that a ten-year-old processor should not be in use? (You should see my car: it's 18 years old. But then it's a Volvo, properly designed and robustly built).

It's not even as if you can buy processors today that are very much faster than my ancient i7-940. Their price/performance may be better, but guess what? I don't care because I *already paid for mine*. Of course, I am referring to single-core performance which is the limiting factor for most desktop applications. The i7-940 has four cores, which I feel is about right for a desktop - any software that does benefit from parallelism will see a significant speed-up.

Perhaps you are a devotee of the cult of technical progress. In which case you should take a long look at the facts, and understand that Intel microprocessors are not a very good example of such progress.

AMD may or may not be drastically better,

Seeing as though AMD CPUs are not susceptible to Meltdown, I would say they have an enormous advantage over intel's. The fact is that Meltdown, unlike Spectre, is very easily exploitable in practical terms, and is the one people should be actually worried about.

A BIOS update would certainly be nice, but it's not necessary. The OS can apply microcode updates (both windows and linux) during boot time. Also, these microcode updates don't survive a power-off event. There is no flash memory on the CPU. The OS would need to apply the microcode on every boot, which is what it does.
