Keyboards have been around for over 40 years and since then not much has really changed in terms of the standard keyboard functionality at the driver/os level.

In the past decade we have seen quite a few keyboards coming out with analogue keys which is great but they are really sketchy to try and actually use for anything as it's not something an OS expects a keyboard to be doing so you need special 3rd party drivers/software which often don't get used in a truly analogue way anyway.

For example in a lot of games analogue directional sticks are the norm, so altering movement speed/sneaking based off the analogue amount is pretty normal, however when you get to PCs you just get keydown/keyup events so you can't process it in an analogue way.

So given we are seeing more keyboards coming out with this functionality at a lower price point is there any company/person/body trying to put together a standard that would allow for analogue key events at OS level or even DirectX (DirectInput) / OpenGl?

I imagine the answer is no, but wanted to ask incase anyone in the know had more info.

Motherboard vendors have begun releasing updated BIOS versions for Intel Core 13th/14th Gen motherboards that offer the new "0x129" CPU microcode that is intended to address the Raptor Lake stability issues that have been causing instability problems and crashing errors for a growing number of Intel Core 13th/14th Gen processors. Intel reported in their (Windows) testing that the 0x129 CPU microcode should offer negligible performance impact but I was curious to run my benchmarks under Linux of this new CPU microcode.

I wouldn't want to find out the hard way. I have a BMD decklink 4k mini monitor PCIe card. I used to use it in a PC, but I upgraded to a laptop. To replace with an external input device is too expensive unless I downgrade capability significantly.

PCIe chassis are more expensive than expected but I've noticed ones that specifically call themselves 'eGPU enclosures'. For some reason when they're marketed to that specific purpose, they cost a lot less, probably because they often don't come with power supplies (which I actually have spare).

I'm looking at 2 such eGPU enclosures and they are a decent price and I think they should work, but I'm a little scared by them specifically saying "eGPU". Would I likely have any problems buying one of those for my PCIe device rather than for a graphics card? Or is PCIe, PCIe regardless?

The AMD Ryzen 9000 series starting with the Ryzen 5 9600X and Ryzen 7 9700X launching tomorrow are some truly great desktop processors. The generational uplift is very compelling, even in single-threaded Linux workloads shooting ahead of Intel's 14th Gen Core competition, across nearly 400 benchmarks these new Zen 5 desktop CPUs impress, and these new Zen 5 desktop processors are priced competitively. I was already loving the Ryzen 7000 series performance on Linux with its AVX-512 implementation and performing so well across hundreds of different Linux workloads but now with the AMD Ryzen 9000 series, AMD is hitting it out of the ball park. That paired with the issues Intel is currently experiencing for the Intel Core 13th/14th Gen CPUs and the ~400 benchmark results makes this a home run for AMD on the desktop side with only some minor Linux caveats.

I'm looking to replace a 6TB G-Drive for my Mac. I'm considering the OWC Express 1M2 NVMe enclosure along with a WD Black 4TB SN850X.

The drive is mostly used as my photography drive. I work off of it with Capture One. About 20% of it is archive data.

I'd like to upgrade to SSD for the sake of longevity and speed. And because I find the ticking and knocking my existing drive makes to be annoying. And because MacOS does this weird thing where opening random apps causes the external HDD to spin up and stalls operation. I fear everyday that this seven year old drive is suddenly going to die on me.

Just looking for some suggestions if anyone's familiar with these OWC + WD products or if you'd recommend something else.

Back at Computex 2024, AMD unveiled their highly anticipated Zen 5 CPU microarchitecture during AMD CEO Dr. Lisa Su's opening keynote. AMD announced not one but two new client platforms that will utilize the latest Zen 5 cores. This includes AMD's latest AI PC-focused chip family for the laptop market, the Ryzen AI 300 series. In comparison, the Ryzen 9000 series caters to the desktop market, which uses the preexisting AM5 platform.

Built around the new Zen 5 CPU microarchitecture with some fundamental improvements to both graphics and AI performance, the Ryzen AI 300 series, code-named Strix Point, is set to deliver improvements in several areas. The Ryzen AI 300 series looks set to add another footnote in the march towards the AI PC with its mobile SoC featuring a new XDNA 2 NPU, from which AMD promises 50 TOPS of performance. AMD has also upgraded the integrated graphics with the RDNA 3.5, which is designed to replace the last generation of RDNA 3 mobile graphics, for better performance in games than we've seen before.

Further to this, during AMD's recent Tech Day last week, AMD disclosed some of the technical details regarding Zen 5, which also covers a number of key elements under the hood on both the Ryzen AI 300 and the Ryzen 9000 series. On paper, the Zen 5 architecture looks quite a big step up compared to Zen 4, with the key component driving Zen 5 forward through higher instructions per cycle than its predecessor, which is something AMD has managed to do consistently from Zen to Zen 2, Zen 3, Zen 4, and now Zen 5.

Zen 5 marks the fifth generation of AMD's winning Zen series CPU microarchitectures that have turned a once written-off company in the processor market back to competitiveness. It seems like just a couple of years have gone by, but AMD Zen is now into its seventh year, and the company has transitioned two desktop sockets, five chipset series, and seven processor lines. The new Zen 5 microarchitecture powers the new AMD Ryzen 9000 series "Granite Ridge" processors on the desktop, the all important Ryzen AI 300 series "Strix Point" processors on notebooks, and the 5th Gen EPYC "Turin" server processors. AMD is planning to launch the new server processors a little later this year, but has dedicated Summer 2024 to its client segment—desktops and notebooks.

The new Zen 5 microarchitecture builds on AMD's proven CPU core technology, and doesn't try anything fancy like its generational counterpart from Intel, the Lion Cove P-core used on Arrow Lake. Zen 5 still brings a double-digit percentage IPC gain over the previous generation, and introduces several efficiency improvements over Zen 4 thanks not just to its newer 4 nm process, but also a host of other innovations. AMD was able to increase clock speeds, and lower TDP across the desktop processor lineup, while still achieving good performance gains.

What's Being Done?

13:30 - the systems deployed for both companies with either one of these processors to within one percentage Point are experiencing the same stability issues even disabling ecores has not fully resolved the issue for one of these companies the error rate also seems to be going up over time on the server side

I've found 2 vintage desktops from around the 2000's era. One already had a broken power supply that won't even turn on (and thankfully didn't break anything else). The other desktop had a working ATX PSU, but it just blew out a few days ago. The PSU is an Elitech LC-B450E and I believe it has 4 molex connectors.

Now, I was wondering, would it be possible to repair the PSU (not that I would do that myself because I don't even know how to solder)? If not, would it be possible to get a relatively new one that's compatible?

Nice example of real reverse engineering at a low level in a ten minute dense summary, including die level comments on structures. Also, why Broadcom sucks in engineering terms (NDA nonsense).
