AMD would have been far ahead of the game if they'd made 1 big ALU, 1 big FPU, and 1-3 little ALUs. They'd have been competitive on single-thread performance while getting a big boost in multithreaded performance without all the c

This isn't always true. Qualcomm Snapdragon 8 Gen 2 has 16B transistors on TSMC N4. Apple A16 has 16B transistors on TSMC N4. One of the biggest disappointments of the new A17 was getting a major node jump and only increasing the trans

If you compare numbers between A510 on TSMC N4 and A16 on N4 (as close as you'll be getting without detailed info about layout libraries), you'll find Apple's little core winning in both performance per watt and overall perfo

The recent crop of unrefined, made-for-experimenters RISC-V chips that have GPUs that are a LOT faster. Add an extra $0.50 to the chip cost and use an out-of-the-box Mali GPU that's several times faster and has better driver support co

I'm much more surprised that they decided to launch with a GPU that would have been considered awful if it had been released with previous pi four years ago.

T-54/55 can shoot while moving, but the accuracy is bad. The real question is whether that matter. If the T-54/55 is going against tanks, it has already losing because those should have been taken out with ATGMs and HEAT drones. I

What is the actual difference between React and Svelte? People don't actually know, but this isn't like the old days where React offered 10x (or more) performance increase over AngularJS without even trying to optimize. We're

React isn't a state manager and why should everyone be forced to use the one "blessed" manager? Despite there being so many, only a handful (redux toolkit, jotai, zustand recoil, and mobx) see much real-world use and they are

The real-world performance difference between Svelte and React outside of the tiny benchmark apps isn't very much. The fact that React can prioritize rendering of some things over others means that it can be slower overall, but still f

Tanks simply peaked in the couple decades after WW2. We increased armor and cannon size a bit, but there's just not much to improve on an armored box. Even the most advanced tanks can be disabled by a mine (not much changed since WW2)

If you're an engineer, physics are always there to smack you in the face. As a result, engineers collect sets of things that physics seem to be fine with and reuse them. If engineering were programming, a woodpecker in Central Park wou

It's not convergence, it's the cycle of development patterns. Patterns come and go leaving bad memories that become anecdotes. Anecdotes become "misunderstanding the paradigm" and even the misunderstandings are long forg

Not everyone has teams of perfect developers given all the time they want to make their perfect frontend app. Most of us deal with average teams where half the devs are at or below par while managing very tight deadlines. The spaghetti from

React is the pragmatic answer. Most devs are of average talent and will hang themselves and everyone else with the stateful webs they weave. Even with careful PR reviews, these things have a way of sneaking in and becoming permanent hindera

Look at actual kills of SU-25 and KA-52 vs the damage they have done. I've seen a single KA-52 mission take down around a half-dozen vehicles and completely halt an advance. That helicopter more than paid for itself in just that one in

I’m thinking of upgrading from my iPhone 12. Lower power 5g, variable refresh, much better camera, moving from 7nm to 3nm, new GPU designed so they finally don’t suck at gaming, AVI hardware decoder, USB C, better battery life, smaller notc

It goes WAY beyond that. In an AR-15, if you put a dot of paint where you would drill the hole for the pin that makes it automatically, that prison time even if it’s never drilled and it’s physically impossible to install the pin for the au

Oil prices dropped from around 2015-2020, but they are back up again. The question has always been "affordable at what price?" The US needs more oil than it pumps. For many industries, exporting good oil and using cheaper oil is a

Any time two phases are being run next to each other, there’s a risk of high voltage. That’s precisely what happened to me (two 277v lighting circuits).

Lots of smaller (kw) circuits is safer than a few very large circuits. The NEC in the US actually stipulates that you must use different receptacle styles for higher ampacities specifically because it is less dangerous. If you run a small a

This is partially done to compensate for terrible wiring. Lots of people are fond of using small wires and going long distances leading to a lot of voltage drop. They often send 125v or so from the transformer which is 123-124 at the panel,

400v 3-phase in a house is crazy to me. I was hit with 480v once (someone cut my lockout and turned the power on). That stuff will outright kill you unless someone else is around to help. One of my favorite things about US residential power

I do wonder where they are headed with the iPad. If you have an M-series iPad, you won't need another for years because the user interface and processing power are sufficient. The only way to change that is introducing more powerful ca

It is a bit more flexible would be my guess. On the flip side, separate arrays and pointers should be slower on modern CPUs because the multiplication will be faster than the cache misses from jumping around in memory.
