From the article: "Meanwhile, unlike the CPU side of this transition to Apple Silicon, the higher-level nature of graphics programming means that Apple isn’t nearly as reliant on devs to immediately prepare universal applications to ta

Yes the Amiga had a form of UMA as did many other systems, the term UMA seems more widely used than "shared memory" its definite not just a marketing term. I don't believe Apple claimed to invent unified memory only that they

From the Anand article you linked further up: "The first Apple-built GPU for a Mac is significantly faster than any integrated GPU we’ve been able to get our hands on, and will no doubt set a new high bar for GPU performance in a lapto

Its not a new term, copying data between cpu and gpu memory has always been expensive: https://docs.microsoft.com/en-us/windows/win32/direct3d11/un... https://patents.justia.com/patent&#x

Memory is unified its just not on die. CPU and GPU and AI share unified memory which means zero copy transfers between them.

I believe the difference in moving parts between a combustion engine and electric motor is about two orders of magnitude (20 vs 2000). I would say "practically no moving parts" is an ok term in relative comparison but thats just m

Did you even read how they attained 75% efficiency on the SOFC with gas turbine? They fed 25% of the fuel to the gas turbine and it was creating at least 25% of the power, they then tried 45% of the fuel with a 50/50 power split. Is a

Aren't you forgetting the weight of the high pressure tanks and fuel cell and heat recovery turbine in your energy density for hydrogen? A battery has power leads coming off of it, hydrogen doesn't, should I quote electrons wh&#x2

>If a modern heat recovery turbine is too complex, then so is an electric motor. A generator is bascially an electric motor running in reverse, at minimum you have a turbine and a generator to make a heat recovery turbine, or you can mec

Then why did you respond to begin with? I was hoping to get something of value out of your non-answer.

I am the one who asked the question and your response did not answer it. I am still not sure what your point is, are you saying Tesla should have no steering wheel check either? Can I get a clear response instead of argumentative rambling?

If a turbocharger is configured to act as a heat recovery turbine it is significantly more complicated including again a generator. Therefore it can not be simpler than an electric motor, this should be obvious. This is referred to as turbo

I thought we where talking about hydrogen which is 2800 wh/kg not methanol which will produce CO2 when used. Now your fuel cell needs 100% conversion to get that energy density in electrical form. Goal post moved, got it.

Turbo chargers are not heat recovery turbines they will not increase and engine thermal efficiency by any significant amount, diesels use turbo charging to increase power they are just as thermally efficient without them. In order to utiliz

I asked what driver checks the Tesla has and you are making what point? It seems based on other actual answers to my question there is only a steering wheel check. Are you proposing there should be no checks and it's purely the drivers

A turbine does nothing by itself again an absurd statement. A heat recovery turbine has a host of support systems to actually recover heat including a generator which is essentially an electric motor to capture electrical energy. I don&#x27

How efficient are algae at making hydrogen vs a solar cell splitting water with electrolysis? How efficient is that vs just charging a battery with the solar cell?
