Bad information for anybody nonetheless rocking a extremely, actually previous Intel processor immediately, because the CPU large has introduced it’s going to cease creating microcode updates to cope with the continuing safety issues attributable to Spectre and Meltdown for sure varieties of structure. The information comes with the discharge of a brand new microcode revision guide that units out the present schedule of deliberate updates for every sort of affected CPU.
If you’ve purchased a PC inside the final couple of years, you ought to be completely high-quality as many of the culled processor architectures date from across the late noughties. As a end result, you’d must be operating an nearly decade-old PC to be affected by this variation in replace improvement.
The solely ones which may catch folks out are a few Intel Atom chips (codenamed SoFIA 3GR) that I’ve listed beneath, as these solely got here out in 2015. However, it’s nonetheless extremely unlikely you’ll really personal a tool with considered one of these CPUs, as these explicit fashions had been aimed toward Internet of Things purposes relatively than client laptops or tablets.
Intel themselves have stated that a part of the explanation why they’ve determined to stop supporting these processors is as a result of “most of these products are implemented as ‘closed systems’ and therefore are expected to have a lower likelihood of exposure to these vulnerabilities.” They additionally stated that the affected processors have “limited commercially available system software support” and that they’ve “micro-architectural characteristics that preclude a practical implementation of features mitigating Variant 2 [of Spectre].”
Here’s a full record of all of the processors that can be lacking out:

- Yorkfield Xeon (Intel Xeon Processor L3360, X3320, X3330, X3350, X3360, X3370, X3380)
If you do occur to have one of many processors listed above, Intel advocate that you just cease utilizing beforehand launched microcode updates, as some patches have been inflicting issues with sure varieties of CPU. While it’s a disgrace these chips will now be susceptible to the Spectre and Meltdown flaws for the remainder of time, Intel have clearly determined it’s not well worth the effort to proceed supporting all these historic processor fashions along with more moderen ones that individuals are really prone to personal.
The excellent news is that Intel expects their new Coffee Lake CPUs to have built-in {hardware} fixes for each safety flaws after they’re launched later this yr. So if you happen to’re serious about upgrading your CPU, you’ll be higher off ready just a bit bit longer.
