<p>Yeah, and in the blog post he mentions that he had to transform the data to SoA. If he had done that alone, he might already have seen a speedup from better cache utilization.<p>Also, I see no mention of alignment in the post. I understand x86/AVX2 likes your load/stores to be aligned, even if it technically allows unaligned access.</p>

<p>As a SIMD noob, one thing that wasn't obvious to me is that SIMD can also speed you up if your mem throughput is underutilized by having the CPU load more data per instruction. It isn't just about compute speedups, which is typically what it's advertised for. Using perf on Linux has been very educational for me to get an intuition for modern CPU performance.</p>

<p>The other issue is that the company obviously has access to the streams nationwide, and they likely don't have the same oversight that a local police might have to document when/how they are used, if they have any oversight at all.</p>

<p>I don't disagree with your views, but attacking Fabien and saying he's being disrespectful seems like a stretch to me.<p>I think a better way to put it is that Fabien's blog is an inspiration to anyone looking to understand computers and programming in detail while taking a history tour of old games and systems. He personally has the skill to do so and then present the interesting bits of the system in a very compelling narrative. It gives people someone/thing to look up to. To find out that part of the analysis/output was produced by an LLM crunching through the code base is a major disappointment since it removes or diminishes the human element of the work.</p>

<p>I came to the comment thread just for this. Casts doubt but then doesn't really justify it. I think these reviewers need to reconcile the fact that these consoles are selling out despite the price increase.<p>Also, Nintendo is on a sphere of its own and the comparison against the Ally is mostly irrelevant. Different kind of audience even though "both are handhelds".</p>
