No no, even better! Peak power consumption is lower, but the same work is completed much more quickly due to increased throughput, so the energy required for the same work is decreased dramatically. Between the performance increase and the lower power usage I wouldn't be surprised if this reduces energy use by 50 %.

Enter Germany, where it was decided DAB is not a federal matter and basically you have 16 small states with entirely different stations available on DAB. The one real advantage DAB could have had, and they threw it away just to auction off the same frequency band a couple more times.

LCDs that aren't optimized for low latency will generally just buffer a full frame before displaying it, coupled with a slow panel these will typically have 25-35 ms of input lag at 60 Hz. LCDs meant for gaming offer something called "immediate mode" or similar, where the controller buffers just a few lines or so, which makes the processing delay irrelevant (<1 ms). The image is effectively streamed through the LCD controller directly into the pixel array.

These animations effectively increase the input lag significantly. Even with them turned off there are extra frames of lag between a click and the updated widget fully rendering.

(Everything below refers to a 60 Hz display)

For example, opening a combo-box in Windows 10 with animations disabled takes two frames; the first frame draws just the shadow, the next frame the finished open box. With animations enabled, it seems to depend on the number of items, but generally around 15 frames. That's effectively a quarter second of extra input lag.

A menu fading in takes about ~12 frames (0.2 seconds), but at least you can interact with it partially faded in.

Animated windows? That'll be another 20 frame delay, a third of a second. Without animations you're down to six, again with some half-drawn weirdness where the empty window appears in one frame and is filled in the next. (So if you noticed pop-ups looking slightly weird in Windows, that's why).

I assume these two-frame redraws are due to Windows Widgets / GDI and DWM not being synchronized at all, much like the broken redraws you can get on X11 with a compositor.

> USB is polling with a fairly slow poll interval rate (think a hundred or so ms).

The lowest polling rate typically used by HID input devices is 125 Hz (bInterval=8), while gaming hardware usually defaults to 500 or 1000 Hz (bInterval=2 or 1). Most input devices aren't that major a cause of input lag, although curiously a number of even new products implement debouncing incorrectly, which adds 5-10 ms; rather unfortunate.

Windows Explorer gets your particular example right: When you copy a bunch of files into a folder, it will highlight all of the copied files after it is done, so it doesn't matter if you saw the progress bar or not.

They were, before the ASICs came. CPU -> GPU -> FPGA -> ASIC. A classic story of specialization.

Historically voice encryption was politically only meant for state use, with strict controls, and us plebs not getting any voice encryption or very weak encryption only. Compared to encryption on the internet, this state has persisted for longer in communications. Even in new communication standards the options for encryption generally offer weak/irrelevant security for modern standards (end-to-end encryption).

How is it a misdirection? The data is accurate and memory latency scaling is a well-known issue for simulations like e.g. games (which is a huge market for high end desktop CPUs and also the market 90 % of reviews address), where you can't really explain the performance differences just by higher clocks. It's considered the main reason why much older Intel CPUs can still outperform Ryzen CPUs in games.

On the other hand, if you take something like Cinebench you can literally turn XMP off (thus using JEDEC timings and bus speed) and still get almost the same score (within, say, 2 %). That's because Cinebench is benchmarking pretty much only ALU throughput. That's obviously an important factor for performance, but just as obviously not the only one.

Clock speed advantage -- Most Zen 2 CPUs don't overclock to 4.5 GHz on any core, let alone all-core. The boost numbers are reached with current firmware, but only for tiniest fractions of a second and never under any real load. Sustained single-core boost frequencies are 200-400 MHz lower than the specified boost frequency. On the other hand, Intel CPUs consistently reach their boost frequencies under load, and most CPUs can do their single-core boost as an all-core overclock under load (with much greater power consumption of course).

In practice this means that for equivalently priced parts (e.g. 3900X vs 10900K) the AMD part will have about a GHz lower clock for lightly threaded workloads, which are most workloads. With Intel settings, the Intel and AMD parts have about the same sustained clocks (3.8-4 GHz) under all-core load, but with the defaults of many motherboards the Intel part will run at 4.8-5 GHz, depending on the cooling.

On the other hand, few applications scale efficiently to more than just four cores. Yes, of course, AMD delivers more Cinebenchpoints-per-Dollar and usually more Cinebenchpoints overall, but that's not necessarily an interesting metric.

Personally I find that if I'm waiting on something to complete that the application in question tends to use only a tiny number of cores for the task at hand. Usually one.

Another significant weakness of AMD's current platform is idle power consumption.

These factors leave me with a much more nuanced impression than "Intel is ded" or "HOW IS INTEL GOING TO CATCH UP TO THIS????"; CPU reviews these days are just pure clickbait.

Pretty much all focal-plane shutters do it beyond 1/60 to 1/250 of a second (identical to the flash sync speed), because the finite movement speed of the upper and lower curtains would result in an uneven exposure otherwise.

That's much larger than the SE (4" screen, 125x60x7.5 mm, 110 g compared to 5" screen, 140x70x7.5 mm, 150 g for the 2020 SE). Which is a really nice form factor, and well suited for apps, but not so good for web browsing.
