tht said: The same physics still applies. CO2, methane, N2, O2 all have various heat transfer characteristics, all verified experimentally. This kind of stuff, electromagnetic radiation absorption, is modeled down to the molecular level. … Thi…

tht said: cgWerks said: Mike Wuerthele said: Nope. Discrete flash and RAM chips on the motherboard that vary per SKU. Oh, wow... I thought the RAM was part of the SoC, too. I was kind of wondering how they did that. Makes more sense…

tht said: 9to5mac, with a link to a Luke Miani video, is saying that the M2 Max to M2 Ultra is scaling better than the M1 Max to M1 Ultra for certain ops, like a FCP export and perhaps some game benchmarks (don’t recall which ones). They spec…

newisneverenough said: Probably this is common knowledge, but why has Apple made so much Not user upgradable? Is it to sell more new machines ? Is it to eliminate technical problems when users upgrade? Conceptually, I want more control of the…

mfryd said: You make a reasonable point that Apple does not offer suitable products for certain market segments. An important question, is what percentage of the overall computer market is being left out. My suspicion is that the consumer marke…

mfryd said: The big issue that people are complaining about is the lack of support for external video cards. Apple's built in graphics are quite impressive, but there exist video cards out there that are faster. So the market that's excluded h…

Marvin said: Hardware RT definitely makes a difference for some things. Some apps only use it properly on Nvidia (Optix), AMD doesn't do so well in Blender: Blender opendata The M2 Ultra is on page 2 and in the same performance range as AMD's 7…

chutzpah said: Depends on what they cheap out on. A plastic enclosure would be cheaper than an aluminium one, but would probably not compromise the experience much, hell it'd make the thing lighter so might improve it. Ditching the earpieces s…

robin huber said: This follows the HomePod model. First release was the high end model, followed by a scaled down cheaper model. Probably true, but how much would be sacrificed in this scaled down model? And, by how much? (Eventually, eve…

tht said: In the 70s, there were models that predicted cooling. The reason for that is not that the physics implementation was bad, it was the input assumptions of what will happen in the future that was bad. Some people projected solar irradian…

tht said: The conclusions from the tweets would be easier to understand if the plots were shown as delta temperatures versus time across 20 to 30 years. Instead the plots are of daily temperatures across a year and 20 to 30 years of daily temper…

chasm said: In my view, this version of the Vision Pro is intended to sell to a) corporate developers and b) corporations, mostly. Some rich enthusiasts will also buy them for bragging rights, I’m sure — in endgame capitalism, some people hav…

Mike Wuerthele said: Fidonet127 said: I think we will look back at this article as a very sad misprint. I can't find where video cards will not be supported. Finally, Mac Pro brings PCI expansion to Apple silicon. It features six o…

Marvin said: By comparison, the M2 Ultra is faster than the 28-core Intel chip and faster (27TFLOPs, assuming both GPUs fully used) than the higher-end Radeon GPUs. Is that really the case, though? Maybe in terms of TFLOPs, but w/o hardware …

Mike Wuerthele said: Sure. To make a long and complex story simple, Intel chips on-die have the ability to address external graphics processors, like PCI-E ones. With that, all you need is a software driver. Apple Silicon does not. All video wor…

AppleInsider said: The reasons why for this are complex. It's not just about drivers -- Apple has decided that it didn't need a way for the Apple Silicon processor to talk to an external graphics card, at all, under any circumstances. Ve…

rob53 said: The M2 Ultra delivers 27.2 teraflops of graphics performance so one current Mac Studio/Pro is faster than the 2005 system. Just be sure to check what it actually does in your workflow. How many teraflops it can do is irrelevant i…

AniMill said: The Mac Pro is a kludge. I’m betting they tried to punch a hole in the sky, but the sky punched back: no 3rd party video card support, and no extended RAM to 1.5TB (for serious math/design labs). An M3 Extreme isn’t likely becau…

Here are a few links I've run across just in the last week or so: https://twitter.com/EthicalSkeptic/status/1667690869380599814 https://twitter.com/EthicalSkeptic/status/1667612638799450113 https://journals.lww.com/health-physics/Fulltext/2022/02…
