  And other Chinese brands!. The MG4 is super popular in Australia too. Can get it for about $38k AUD ($25k USD).

  Even if Tesla wasn’t tarnished by association with Musk, they have absolutely nothing at the budget end of the market. ie for buyers that traditionally bought corollas, little Mazdas and Hyundai’s.

  And BYD has the whole range, if I want a luxury sedan the BYD Seal goes toe to toe with the model 3.

  I think China is going to eat everyone’s lunch here in the same way Japan did in the 70s/80s, and Korea went in even cheaper in the 90s and 00s (how many Hyundai Excels/Accents were there in Australia in late 90s early 00s).

  One of the biggest bottlenecks in many workloads is latency. Cache miss and the CPU stalls waiting for main memory. Flash storage, even on an nvme bus is two orders of magnitude slower than ram.

  For example L3 cache takes approximately 10-20 nano seconds, ram takes closer to 100 nano seconds, nvme flash is more than 10,000 nano seconds (>10 microseconds).

  Depending on your age you may remember the transition from hard drives to ssds. They could make a machine feel much snappier. Early PC ssds weren’t significantly faster throughput than hard drives (many now are even slower writing when they run out of SLC cache), what they were is significantly lower latency.

  As an aside, Intel and Microns 3d xpoint was super interesting technically. It was capable of < 5000 nano seconds in early generation parts, meaning it sat in between DDR ram and flash.

  Gigabytes plural? Maybe a while. Gigabyte singular? Already a thing. AMD EPYC 9684X(www.amd.com/en/products/…/amd-epyc-9684x.html)

  I never had one (but did want one, just financially couldn’t justify it at the time), but it would have a great fit for me. I just wanted a watch to tell the time, and display my phone notifications plus vibrate to alert me to them. That would have been legitimately useful for the job I was in at the time which was challenging to carry a phone (but it was nearby in my bag).

  Now, I have no use for any of that. But I am now interested in a heart rate monitor that doesn’t hoover my data to replace my old dedicated Polar heart rate monitor (which also told the time, but I only wore it exercising), so the more expensive model is tempting!

  This is one of my motivations for dumping my games and modding my consoles. Pull out Wii sports and it doesn’t work? No problems I’ll run it off usb.

  While not hard drives, at $dayjob we bought a new server out with 16 x 64TB nvme drives. We don’t even need the speed of nvme for this machines roll. It was the density that was most appealing.
