No. A read-after-write hazard has not stalled a cpu in the last 10 years. So the article will mislead all the beginner architects out there. A clear explanation of dependencies would be much more appropriate.
- brigade 13y agoIntel released Atom not 6 years ago, and is still selling Bonnell-derived CPUs to this day... Cortex-A7 and A53 are in-order as well, and are/will be quite common among low-end Chinese smartphones and tablets.
- weland 13y agoThere are CPUs that have been stalled by RAWs and appeared in the last 10 years, and they are here to stay. That being said, I think the downvotes are unfair on your post. The author of the post is writing about CPUs that are indeed unlikely to be ever stalled by RAWs.
- Tuna-Fish 13y agoSadly, this is only true on proper desktop cpus. For an example of a CPU that does horribly on RAW hazards, look no further than the Xenon CPU in the XBox360.
