You keep dodging several facts.
First, this appears to be an old, unsupported benchmark. It's not supported by Unity, it might as well just be some hack by a Unity engineer who may no longer be with the company.
Second, Speedometer is an official benchmark and is actively supported by developers who periodically change the code (hence, Speedometer 3.0).
I agree with the critics that Speedometer is a pretty useless benchmark but I flatly believe that web browser benchmarks are useless in general because no one only uses a web browser for visiting sites that use one and only one specific web technology. And I've been surfing the World Wide Web since late 1993/early 1994 (NCSA Mosaic running on UNIX workstations).
Third, you are repeatedly and blatantly ignoring the fact that this benchmark is crashing on x86-x64 powered Windows PCs (and not just mine).
For what it's worth, this "benchmark" is crashing on a Ryzen 7 3700X CPU, B550 motherboard, RTX 3060 GPU, running Microsoft Edge on vanilla Windows 10 Pro 22H2, with the latest drivers, updated firmware, yadda yadda. Not exactly a bleeding edge system.
There are other Windoze system in the house. I have a Radeon RX 580 graphics card. I'm most certainly not planning on moving hardware components around trying to get this stupid benchmark to run.
As to the issue with M1 Macs crashing earlier with Speedometer I don't remember that because I'm no benchmark score chaser. I don't keep track of that sort of stuff. In fact, I anticipated that there would be software incompatibilities when Apple Silicon was new. I waited 2.5 years for the M2 SoC to upgrade my Intel-powered Mac mini 2018 to Apple Silicon. For sure there would be some software compatibility early on.
Some dude on TPU asked me to run a benchmark. I did and said it crashed. That's the extent of my participation in this type of thing because web browser benchmarks are ultimately a failure at measuring usability.
I just need a web browser that will behave politely on the top 50 or so sites that I use. It's more important that my web browser doesn't crash when accessing my brokerage account's site, Amazon.com or SeriousEats.com, not some random lame benchmark. For someone else, it might be Facebook, TMZ, and Etsy.
Again, the burden of this benchmark's crashy behavior is on the writer of the benchmark code. I have no idea who that person is nor any idea how to get a hold of them. If you find out, point that person to this discussion thread. Then ask them why their benchmark is crashing MS Edge on a vanilla Windoze 10 box. Their response will pretty much tell whether or not they actually know anything about publishing quality code.
Just because some can post something they label a "benchmark" doesn't mean they're actually competent at writing such tools. In the same way, someone could post some shït recipe that produces a wheat flour hockey puck that they label "bread roll."
