the nvidia 12VHPWR shitstorm continues!

I work as a software engineer and I have a RX 6750XT for gaming, but recently I've been receving requests for AI applications that I'm quite unable to run locally because I don't own an Nvidia GPU.

My motherboard is an ASUS B650M-A WIFI II, it does have 2 PCI x16 slots, and since I'm quite happy with the performance I get from my 6750XT, I was thinking in buying an Nvitia RTX 4060 or 3060 even, a cheaper RTX GPU just for AI training locally.

What do you guys think? Would I lose any performance in gaming? I would like to avoing switching GPUs and I've got a 850w PSU that prob can handle both at the same time just fine.
Also selling my AMD and using the extra money to buy a 4070 or something is our of question, I live in Brazil and anything over a 60 model gets really expensive here.

My setup currenly is:
Ryzen 5 7600 (water cooled)
RX 6750 XT (oc)
32GB RAM
850W PSU (80+ gold)
1 SSD 2TB gen4 NVME
1 SSD 1TB gen3 NVME
1 SSD 1TB sata
1 SSD 500gb sata

As I wrote before, Thunderbolt now is essentially a certification program for certain USB4 devices and for PCs, there's no difference currently in practice.

With USB4 version 2.0, the program will be called Thunderbolt 5 but the way I read it, Intel is planning to restrict the certification further on lighter workstations. Read this page

Laptop charging: Thunderbolt™ 4 technology for thin and light notebooks that require up to 100W to charge. Thunderbolt™ 5 technology for laptops that require up to 140W to charge. 140W‒240W is available on some devices.

Seems like a small change, doesn't it? Wrong. This is a very big change which tests the clout of Intel against the will of Lenovo/Dell/HP. Let me explain. For near two decades now, all business laptops charge over 20V. From 2014 to 2019, the USB C specification only allowed up to 100W by using 20V 5A. This didn't faze much the big three and they have their proprietary 20V 6.5A (or so) docks. Lenovo even created such a charger last year when PD 3.1 was already out for some time with the appearance of the ThinkPad Z16 and the Z16 Gen 2 this fall still shipped with that (meanwhile the consumer Legion line switched over with the C135 being proprietary last year and the C140 being PD 3.1 this year). At higher wattages they are using proprietary power plugs and combo cables which allows their customers to dock with plugging a single cable and charge at basically any wattage up to like 230W. This means the incentive for PD 3.1 is not really that big.

Now, in 2019 the USB IF raised the wattage but since the connector didn't change, the amperage needed to stay put and so they raised the voltage. This is the big change. If I am reading correctly and Intel will deny certification unless the manufacturer uses PD 3.1 then the big three needs to augment their laptops and docks to support 28V. But also depending on how strict Intel goes, TB5 certification might require downright abandoning their proprietary means because the USB C specification doesn't allow proprietary charging protocols over the C connector (yes, all your phone chargers which support Qualcomm QC over C are not specs compliant).

Will they care? Macbooks with plain (not Pro/Max) CPUs also shipped as USB4 because they do not conform to TB4 requirements of dual displays and it doesn't seem like this made a dent in sales because we are now three generations in and Apple didn't change the capabilities of their lowest tier CPU. On the PC side, AMD models only ship with USB4 too and who cares?

Does Intel have the clout in 2024 to force laptop manufacturers to the new standard or will they shrug and say they don't need a Thunderbolt 5 sticker on those laptops then? Stay tuned, this will be interesting.

x86 came out 1978,

21 years after, x64 came out 1999

we are three years overdue for a shift, and I don't mean to arm. Is there just no point to it? 128 bit computing is a thing and has been in the talks since 1976 according to Wikipedia. Why hasn't it been widely adopted by now?

Heya, this article is a must-read for everyone who is into GPU's:

https://www.pcgameshardware.de/Geforce-RTX-4090-Grafikkarte-279170/Tests/Die-beste-Grafikkarte-2024-Teil-1-4K-Ultra-HD-1433940/

Content as far as I see it:

- 20 new rasterizing games
- 10 advanced ray tracing games
- 4 resolutions tested (Full HD, WQHD, UWQHD, Ultra HD)
- Demanding custom GPU sequences for every game (videos included)
- Latest drivers and game versions
- "Leistungsindex" = Performance Charts for every GPU and res.
- Energy efficiency and price/perf analysis

That's both quality and quantity. The text is in German, but every benchmark is written in English (and quite detailed, I'd say). Use Google (Chrome) translate for the full package. :)

So my personal laptop is a Lenovo (gaming), and my work laptop is an Asus.

Here is the weird thing: despite the fact that my personal gaming laptop has better specs in every way, I feel like my work laptop is more "stable". You know, those "windows moments" like silly bugs or lags here and there, they are more present in my personal laptop.

Why do you think that might be? The first possible reason I thought of was that maybe some brands make better drivers for their components?

So I've struggled to find a sub that I can ask this question, since dedicated technology news subs just only let you post links to news and not actual discussion of news sites. I used to read a combination of Engadget, Gizmodo, and The Verge for general tech news. This is over a span of a decade or more. Gizmodo was always a cesspool, but I guess I wasn't very mature and could overlook how juvenile it was. It eventually got sued into oblivion along with Gawker's whole network. I had abandoned it years prior. The Verge has always been a vomit of unorganized news stories with a heavy hipster, progressive vibe. I dabbled in it for a bit but got tired of it. The one I've mostly leaned on was Engadget. It wasn't always the most in-depth, but it didn't have to be. It had my most coveted format, which was chronological blog style where you can scroll from top to bottom and see all the posts until you reach the last point you stopped at. It was great for completion and FOMO. I just wanted the news, a general smattering of everything, not exntensive deep dives, and most definitely not politcally charged opinion pieces masquerading as news. But of course, like much of the internet, it's leaned heavily to the left, and has turned every product reveal or social media revelation into an angry social justice diatribe. I'm getting so tired of it. The latest fiasco is a hit piece on Elon Musk and the newly released Cybertruck. It's been around for years, and they've covered it objectively enough for years, but somehow all that professionalism has been thrown out the window in favor of railing against how this new truck will somehow kill people on purpose, because they can't get past their personal hatred of Musk. I want facts, not your deranged opinion. Cost, release date, charging standards, stuff like that. They have also recently vomited maybe 200 "listicles" during Black Friday in a sorry attempt at ad spamming. I really need a replacement tech news site. Something blog style that covers a wide breadth.

Hello everyone,
I just bought a new PC, here are the specs:
Case: Fractal Design Pop XL Air RGB
Power supply: Corsair RM850X 850 watts (80+ gold)
Motherboard: ASUS TUF Gaming B650-Plus Wi-Fi, AMD B650
Processor: AMD Ryzen 7 7800X3D 8x 5 GHz
RAM: 32 GB DDR5 PC-5200 RAM (2x 16 GB)
Graphics card: AMD Radeon RX 7800 XT 16 GB, any manufacturer
SSD M.2: SSD NVME M.2 2 TB Kingston NV2
Wireless LAN: integrated WiFi 6 wireless LAN + Bluetooth module
CPU cooler: Be Quiet! Dark Rock 4
Operating system: Windows 11 Professional 64-bit
But it's impossible to connect any Bluetooth device (including my Sony XM4 headset, which I'm interested in, but also other BT sound devices).
I've followed all the tutorials available on the Internet (check the BT drivers via Task Manager, search for the headset manually via BT settings, update Windows...).
I'm starting to go round in circles and I can't figure it out anymore... Any ideas?
Thanks a lot!

So I’m getting a 7900XT and it comes in today. Right now my build is 3x1TB Samsung SSD’s 32GB of Corsair vengeance 3200MHz DDR4 750W 80+Gold PSU Ryzen 7 5800X

You think I’m able to put my graphics card in when it arrives and be fine? If you have an questions about my computer and what’s in it let me know!

I am planning to go to another country in dec but its only a 3.5 hour flight at max, and a 65w power bank near me is around $70 usd, and id rather buy a game with that, i am going there for my sister's wedding so ill be out of the house for most of the days but taking my ally would seem rude rather than paying attention

Hey everyone,

Our professor just assigned us the task of building a mouse from scratch using C programming and Leonardo Arduino. It's an exciting challenge, but a bit overwhelming for us newcomers.

Any advice, resources, or tips on diving into C and Arduino for a mouse project would be incredibly helpful. How did you approach similar tasks?

I can't afford buying a new psu right now and the warranty is expired.

From what I've read online it might be a broken fan controller, if that's the case would a simple fan replacement fix it or is that component soldered in the psu.
