• Netgear's Nighthawk RS700 delivers WiFi 7 for $700.  (Liliputing)
  
  It has 10Gb WAN and LAN ports - though only one of each - and four gigabit ports for some reason.  It's really time for 2.5Gb to become standard on all but low-end equipment, certainly on switches and routers.
  
  WiFi bandwidth is a theoretical 19Gbps, but of course that's divided among all the devices on the network.

• Following swift and decisive action from the federal government, the American banking system is once again on a firm footing and no further troubles are anticipated well fuck.  (Yahoo Finance)
  
  Shares in First Republic Bank dropped by 62% yesterday and Western Alliance shares dropped by 47%.
  
  Wall Street analyst Robert Kiyosaki, who predicted the Lehman Brothers collapse in 2008, said there was no reason for investors to panic but it might be time to stock up on canned food, guns, and ammo.  Well, he said silver and gold, but you can't eat those, or fight off the zombie horde.

• AMD's upcoming Ryzen 7640U looks to be a great chip for thin-and-light laptops.  (WCCFTech)
  
  The U series is rated at a 15W TDP, where the HS chips are 45W and HX are 55W.  The 7640U manages to get within 10% of the fastest laptop chips at an power rating on single-threaded tests, and is 60% faster than the previous generation's 6600U on multi-threaded tests.
  
  It's a 6 core chip, so it's not going to match a 24 core 13980HX, but it's not going to set your pants on fire either.

• This just in: Silicon Valley Bank is still splut.
  
  
  
• 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.
  
  
  
• Google hired thousands of employees it didn't want or need just to make the company look bigger - and to make them unavailable to competitors.  (Yahoo)

• 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)
  
  You probably will see your money, since assets significantly exceeded deposits, but now that the government is involved it won't be quick.
  
  
  
• 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.
  
  
  
• G.Skill has announced 8GHz 24GB DDR5 memory modules.  (WCCFTech)
  
  Pricing was not announced.  It will be interesting to see what it costs - and what voltage it runs at - because that is faster than LPDDR5X laptop memory.

• 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.)
  
  
  
• The Solidigm P44 Pro seems like a decent SSD if you can find one for a decent price.  (Hot Hardware)
  
  Who the hell is Solidigm?  Well, a while ago Intel sold its consumer SSD division to Korean group SK Hynix.  This is them.
  
  Also, Nextorage is Sony.  Why they don't just call it Sony I don't know.

• A team at the University of Rochester has discovered the Holy Grail of physics - one of the Holy Grails of physics, for there are many - a substance that acts as a room temperature superconductor.  (Science)
  
  Or so they say.  Nobody trusts them because they're not releasing the details, and Nature retracted a paper from the same group last year after nobody could replicate the results and they refused to release any more data.
  
  It looks like this one is just warmed-over cold fusion.
  
  Quanta also has a writeup of the story that may be more accessible.

• AMD's 7745HX appears to be as fast as Intel's 13700HX.  (WCCFTech)
  
  The 7745HX is the low end of the high-end Dragon Range family of laptop chips, with 8 cores; the 13700HX has 16 cores (8P + 8E).
  
  On the other hand, the 7745HX uses 50W when playing games, which is a lot for a laptop chip, where the 13700HX uses 80W.
  
  Oh.  That's the same hand.
  
  
  
• 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.
  
  This quote is spot on, though:

  "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.

• Build your own database from scratch.  (Build Your Own)

• The Arm Cortex X4 in the Snapdragon 8 Gen 3 could be clocked at 3.7GHz.  (WCCFTech)
  
  I didn't even know there was a Cortex X3
  
• Which might explain why phone makers are flailing about looking for the next big thing.  (Tech Crunch)
  
  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?
  
  
  
• In a similar vein if you're gaming at 2560x1440, the 65W $249 Ryzen 7600 delivers 90% of the performance of the 320W $589 6GHz Intel 13900KS.  (Tom's Hardware)
  
  Because games rarely need more than six cores.  If you're doing 3D rendering or computational fluid dynamics, different story.  But you're probably not.
  
  (I had a simple task to do today that totally wedged my laptop for an hour and a half.  I really do need something better, but again a 7600X would probably do.)
