• No, Apple's A17 Bionic mobile CPU is not going to be 59% faster in single-threaded performance than the A16.  (WCCFTech)
  
  As a rule of thumb, CPU performance rises with the square root of the issue width, and complexity and transistor count (and also power consumption) rises with the square of the issue width, so to increase performance by 59% without increasing the clock speed Apple would need to make a chip more than six times larger using six times the power.
  
  Increasing the clock speed by the same amount would have similar effects on power consumption.
  
  And both approaches have limits where requirements zoom off the charts for minimal gains.  You can see this in existing chips, where the 170W Ryzen 7900X is only 7% faster than the 65W 7900 non-X model.
  
  This supposed leak is garbage.

• Pimoroni's DV Stick will use two RP2040 chips to provide a retro-gaming tinkerer's delight.  (Tom's Hardware)
  
  The RP2040 is the chip in the Raspberry Pi Pico.  It has no video circuitry at all, but it is flexible enough nonetheless to generate and encode an HDMI signal.
  
  That keeps the chip pretty busy, so Pimoroni has added a second RP2040 to act as the CPU while the first is being the the video chip.
  
  Each chip has 256k of RAM, more than enough for old-school games, though the included language of choice is MicroPython rather than Basic.
  
  
  
• At the higher end of the gaming scale, AMD's 7800X3D is almost here.  (Tom's Hardware)
  
  AMD launched the more expensive 16 core 7950X3D first, knowing that everyone would buy the cheaper 8 core 7800X3D if it were available.  At $449 it averages 20% faster in AMD's admittedly selective benchmarks than Intel's $589 13900K, while also using much less power.
  
  It's slower for heavily multi-threaded tasks - if you want to game and also run particle accelerator data analysis you should go for the 7950X3D.  Unless you live above the Arctic Circle where the 13900K's furnace-like qualities would be a net win.

• Silicon Valley Bank, with $175 billion in deposits, went splut and has been taken over by the FDIC.  (Tech Crunch)
  
  This doesn't appear to be the usual Ponzi scheme or outright theft that we have become familiar with in recent years, but instead a good old-fashioned bank run.  SVB apparently held 97% of its $209 billion in assets in long-term mortgage-backed securities.
  
  Which is fine unless rumours start circulating of trouble at your bank and more than 3% of your customers want to withdraw their money at the same time.
  
  Which is exactly what happened.
  
  
  
• SBV is - was - a proper, regulated bank so if you had less than $250k in your account it's insured and you'll have access to it on Monday.  If you had half a billion in there - like Roku - you're not going to be seeing your money any time soon.  (CNBC)

• If you were holding funds in the USDC stablecoin you should also start panicking.  (Tech Crunch)
  
  Circle - the company running USDC - says it held $3.3 billion in liquid reserves at SBV.  The whole point of a stablecoin is that it is backed 1:1 with cash equivalents at banks, and apparently that was the case, right up until the bank ceased to exist.
  
  The result has been billions of dollars in transfers of USDC and congestion and soaring gas prices on the Ethereum blockchain, which to be fair is what happens any time a gnat farts in the crypto world.

• The EU, being run by retards, effectively banned 8k TVs.  (Tom's Guide)
  
  8k TVs use more power than lower resolution models, and the EU set power consumption limits that would require 8k TVs to run at miserably low brightness settings.
  
  So Samsung, not being run by retards, set its 8k TVs in Europe to run at miserably low brightness settings out of the box, with a button to turn off the crippling eco mode, which since it's an action by the individual and not the company does not violate the regulations.

• Need a workstation with 120 cores, four high-end Nvidia graphics cards, 2TB if RAM, and 28TB of SSD, but you also want it to look cool?  Lenovo has you covered.  (AnandTech)
  
  As long as someone else is paying, because that configuration will cost over $100k.
  
  They do have smaller, cheaper models, but none of them are actually small or cheap.

• If you want to build a small, cheap workstation/server - for example in a discontinued Silverstone case that arrived at your door yesterday - here are a couple of tips.
  
  Gigabyte's B650I is a solid motherboard with three M.2 slots, four SATA ports, and 2.5Gb Ethernet.  It can drive three displays over DisplayPort, HDMI, and USB-C (one of each).
  
  That's an AMD motherboard, but AMD CPUs use less power than Intel, even when they have the same 65W power rating.  The 7900 for example peaks at 89W, and is 50% faster than the 13500 which peaks at 151W.  Not a drama in a desktop system but these cases are quite small and will be packed full of drives, so I want something relatively low power.
  
  Silverstone, the same company that made the case, also makes an M.2 SATA controller.  The case can hold eight drives, and the motherboard only has four SATA ports, so this is handy.  There are other models, but this one comes with a chunky heatsink, which is apparently a necessity if you want these little controllers to work consistently.
  
  And if you want something faster than the built-in 2.5Gb Ethernet, since the PCIe slot is still free you can add a dual 25Gb Ethernet card for about $80.  Which is crazy overkill for a small server like this but the price can't be beat.  25Gb switches aren't cheap but it will work fine with 10Gb SFP+ switches or RJ45 transceivers.  (25Gb Ethernet uses SFP28, which is not the same as SFP+, but is backwards compatible.)

• GDDR7 uses PAM3.  (AnandTech)
  
  GDDR7 is the next generation of memory for video cards, and will be about 50% faster than the latest current GDDR6X (and twice as fast as typical GDDR6).
  
  PAM3 is more interesting: It's trinary.  It runs at three voltages, -1, 0, and 1.  This allows three bits to be encoded as two signals - there are nine possible values and 0, 0 is treated as an error.
  
  The upcoming USB 4 v2 (which will hopefully become USB 5 before it arrives) also uses PAM3 to reach speeds of 80Gbps, twice as fast as regular USB 4.

• ChatGPT broke the EU's plan to regulate AI.  (Politico)
  
  Faced with regulating the thing they are trying to regulate, Europe's plans have fallen into chaos.
  
  I just want to say that this article is dumb, Politico is dumb, the EU is dumb, and ChatGPT is particularly dumb.

  "These systems have no ethical understanding of the world, have no sense of truth, and they're not reliable,” said Gary Marcus, an AI expert and vocal critic.

  Phones are basically good enough.  You can keep using them until they break, and then buy a new one.  And there's not much difference between a midrange phone and a flagship model, except that the flagships tend to be missing things like headphone jacks and micro SD slots.
  
  Speaking of which, the Galaxy Z Fold 3 seems to be selling at half price, which makes it only a horribly expensive small Android table rather than a psychotically expensive small Android tablet.  Apparently the Fold 4 is out, which again, I didn't notice because honestly who cares?

• Iran has struck lithium - an estimated 8.5 million tons of it.  (The Register)
  
  That sounds like a lot - and it is.  Global lithium production in 2021 was estimated at 100,000 tons, half of it from Australia.  But there's an estimated 6 million tons just sitting in the Salton Sea stinking up the place.  Lithium is not particularly rare, and not all that valuable, so not a lot of effort has been put into finding more of it when we already have enough for 300 years.
  
  You'll sometimes see figures that by 2030 we'll be using 3 million tons of lithium per year, but that's actually lithium carbonate - Li2CO3 - which is only 10% 20% lithium by mass.  Even at that rate known reserves will last more than a century sixty years.
  
  
  

• So I woke up this morning and for the first time this year I didn't feel an overpowering urge to go right back to sleep.  I didn't get as much done today as I had planned but I did actually get something done.   I washed the floor in the laundry, for example.  I had intended to wash some clothes, but that's not quite how things worked out. 
  
  
  
• Also accidentally bought a couple more computer cases, even though I just bought two expensive Hololive limited edition computer cases that I haven't put anything in yet.
  
  Before I accidentally bought a house last year I was rebuilding my home office, and one of the things I had planned was to build a couple of custom NAS boxes using Silverstone's CS01-HS.  It's an aluminium mini-ITX case with six 2.5" hot swap drive bays plugging into a SAS/SATA backplane, which is not something you normally find in mini-ITX cases, plus room for another two 2.5" drives inside, which is a little more common.
  
  Anyway, fast forward a year and I'm looking at cheap options to get a computer in every room of the new house (which has too many rooms) and I tripped over the CS01S-HS on Amazon.  That's the silver version; I had planned to get one each in silver and black, but apparently the entire range has been discontinued in the past year and Amazon only had a couple of remnant silver models in stock.  I said to myself that I would have bought them if they still had both, but since they don't, I moved on.
  
  And then found the black version under a separate listing, even though the silver version showed the black version as sold out.  And they only had one of the black version, so if I missed out now that was it.
  
  So I bought both.
  
  And now I have to figure out what to do with them.  It's a mini-ITX case so you only have one PCIe slot, and the case itself only provides room for a half-height, half-length card.  And there are very few mini-ITX motherboards with eight SATA ports (even this one only has six and it ain't cheap) so that slot is pretty much dedicated to a SATA controller.  Only pretty much, because you can now get five and six port SATA controllers that fit in an M.2 slot.  I'm not sure why those exist when the one case that would require such a thing has been discontinued, but they do.
  
  My first thought was to use the Ryzen 5700G, which still has the fastest integrated graphics of any readily available desktop CPU.  But that's Socket AM4, and a quick search found exactly one Socket AM4 mini-ITX motherboard in stock in Australia, and that only has gigabit Ethernet, so I'd need to use the sole M.2 slot for a SATA controller and the PCIe slot for 10GbE, which wouldn't leave me with a boot drive separate from storage.
  
  Probably best to use a current model motherboard with at least 2.5Gb Ethernet and not worry about the graphics.  If I want to do media transcoding an Intel CPU is probably the way to go, even though it's worse for gaming.
  
  Why a 2.5" NAS?  As I mentioned yesterday, SSDs have already fallen in price by 30% this year.  I'm going to stuff it full of cheap SATA SSDs and run ZFS.  It won't be cheap, but good dedicated NASes aren't cheap either, unless your employer happens to be throwing them out...  Which is why all my Synology boxes date back to 2013 and really need replacing.
  
  
  
• The importance of being ECC.  (Robert Felder)
  
  At least DDR5 has on-die ECC, and some really weird systems with nominally non-ECC RAM have block ECC as well.  I wonder if any regular motherboards have support for that, since it seems you can do it with regular Intel CPUs.

• Although that Gigabyte Aero 14 OLED laptop I mentioned yesterday is very tempting, the truth is now that I've settled in in New House City I only expect to travel any real distance about once a year.
  
  And for the same price as that laptop (13700H, 16GB of RAM, 1TB SSD, RTX 4050) I can get a desktop system with a 13500 (almost exactly the same as the 13700H laptop chip), 128GB of RAM, 2TB of SSD, and a Radeon 6700...  And 24TB of hard disk storage as well, just because.
  
  So I think that's what I'll do.

• Prices of SSDs are in free fall because (a) nobody is buying anything and (b) there isn't a cartel propping prices up.  (Tom's Hardware)
  
  Western Digital's 1TB SN770 - a basic but generally decent drive - has dropped from $90 at the beginning of January (and since it is still February that's less than two months ago) to $60 today.  The 2TB model is also great value at $120.
  
  Prices are expected to continue falling at a slower pace during the year.  Manufacturers are cutting production but since it takes months for wafers to go through the pipeline and turn into chips that get put into SSDs, that's going to take a while to have any effect.

  If they had a 32GB option, it would be the perfect small laptop.
  
  They do not have a 32GB option.
  
  There is a larger 16" model with a 3840x2400 OLED display, RTX 4060 or 4070 graphics options, and actual DIMM slots so that it's not instant e-waste.  But that's also 40% heavier.
  
  And 30% to 50% more expensive.

• The 7950X3D is not four times faster than the regular 7950X when using the integrated graphics.  (Tom's Hardware)
  
  The original story from PC Magazine has been updated to reflect the fact that the figures for the 7950X were originally taken with an outdated driver that gave radically lower than normal performance.
  
  The updated tests now show that the integrated graphics performance of AMD and Intel's desktop chips is basically identical.  AMD provides one sixth the performance of last year's laptop chips, where Intel provides one third the performance of this year's laptop chips, but AMD's laptop chips from last year had twice the graphics performance of Intel's chips from this year, so for example the racing game F1 22 gets exactly 33 fps at 1080p, lowest quality, whether you're on a 7950X, 7950X3D, or 13900K.
  
  Or a 13500, which seems like the best option from Intel's desktop lineup.  Six P cores and eight E cores at 65W.  I'm thinking of getting two 13500 systems rather than one big 7900X or 7950X system

  I'm not planning to buy either one, though.  There's notable benefit for non-gaming tasks and the required drivers make everything more complicated.  At least with Intel chips the P cores are always faster than the E cores.  On the X3D chips, which cores are faster varies with the application.
