Quick anecdote on how Secure Boot can fuck up booting: I couldn't boot in a Hyper-V VM because I enabled Secure Boot on it thinking it's UEFI mode, even though it's UEFI by default, and I couldn't boot into Windows 7 on my old PC because it also had Secure Boot enabled. In both cases disabling one setting made the system boot up perfectly fine in UEFI only mode.
A windows update did some fucked up things related to UEFI and it took me a while to figure out why windows was missing. While inspecting C: looked really weird and empty, it looked like the windows directory itself had been deleted among other things. In the end, nope, C: was now G: for reasons unknown and an USB-drive was C:

Good times.
 
Oh, not those. The ones I were thinking of are SFF-8644 cables. They were originally made for SAS drives, but can also be used for PCIe with the right adapter.
In any case though, oculink is generally cheaper.
I've used those. They're good up to PCIe4, but beyond that you'll need something better, like MCIO.

This is a slide directly from the AMD launch video. if the lowest price of this card rises to $700+, is that what 1440p pricing is these days? :story:
No, it's special "4K and 1440p" pricing.

[Update – No Missing ROPS] NVIDIA’s RTX 50 Laptops Are Rumored To Witness a Production Delay; Retail Launch Now Expected By April-May
Update [3/7/25] - NVIDIA has confirmed with The Verge that the GeForce RTX 50 Laptop GPUs are not affected by any missing ROPs issue. As such, the previous report seems to be inaccurate, and we shouldn't expect any major delays in production or a potential recall.

Intel will keep using TSMC's services even when 18A is ramped up: 'It is a good supplier'

It's sad PhysX never reached its full potential. Games today have worse physics than games 10 years ago.
PhysX is still around. Nvidia open-sourced it and it's used in pretty much all the popular game engines. DF talked about this on their podcast but the big change came from consoles becoming the dominant platform for AAA and most console devs preferring to focus on cutting edge visuals instead of heavy physics simulation.

The issue isn't so much the technology being dead as it is normie niggercattle goysumers not caring about physics in games.

Also, CPUs aren't constrained by physics now being multithreaded and multicored.

Physics are visuals. The problem is if you implement physics (like fluttering cloth) that don't work on consoles, that's a substantial amount of work that most of your customers will never see.

Also, CPUs aren't constrained by physics now being multithreaded and multicored.

They absolutely are. For example, simulating a cell phone hitting a corner, flexing, and crap popping out of it, a process that takes perhaps a tenth of a second, takes a 16-core Ryzen 9950X 45 seconds to simulate:


Want remotely realistic crash physics in a racing game? This simulation takes that same Ryzen over 11 minutes to run:


Results for various CPUs:

The reason so many physics simulations use GPUs is they have a shitload of FP32 compared to a CPU. If you have an 8-core CPU with 2x256-bit SIMD per core that runs at 4.5 GHz (e.g. a recent Ryzen CPU), for FP32, that's 256/32 x 2 x 8 x 4.5 = 575 GFLOP/s maximum. By contrast, a GeForce 4060, non-Ti, can push 15,472 GFLOP/s.
 
So I'm an idiot, and I didn't consider this until now because, again, I'm an idiot. The Prime 9070xt from asus connections:

I have a super flower Leadex III 750w power supply; and the cables provided are 2 dual-6+2 pin VGA adapters. I'm seeing guides like this:


featuring this image:

and I'm wondering if using both dual 6+2pin cables as in the 4th illustration for Three PCIe Slots would suffice over a 12vhpwr cable. Or if getting a couple 2x8pin cables might help. If not, might there be a 12vhpwr cable that I can use? It appears the super flower PSU has the following connections:

Sorry to bother you guys with this, I know you all likely have better shit to do than consider my ignorance on this subject. Seasonic seems to suggest it'd be fine but you folks know your stuff better than I and I thought it couldn't hurt to ask.

Thanks.

As far as I can tell the math checks out for the 3x 6 pin connection. I'm not a domain expert so I don't know as much as someone who has done this forever but the math for power requirements and current limits of cables checks out. I just did the calculation for power consumption and resulting amperage.

Is this in general? I have a Corsair RM750e powering my RX 6750 XT, using a single PSU side connector going to my GPU's dual 8 pin. Should I change this?
I'm using a 6750XT right now, with a single cable that ends in 2 6+2 pins connected, and it works perfectly. I would assume you're fine, but these people are far better with this stuff than I am.

Now I can add GN's video:

What I cared about most, the power efficiency:

At this point I may be the only person that is more focused on the non-xt version. Will only get one MSRP though.
 
how is there 9070 XT stock where you guys live I just checked on pc parts picker and it seems most of the close to msrp and most others are out of stock (i live in uk) the 9070 still seems to be in stock though

Its fine but I have a RM650 (2019 ver.) so no biggie. Would have upgraded to a SHIFT model when I get a 9070.

It was a very short window(probably 40 minutes?), and I live in the middle of nowhere. I went to Bestbuy in person, and when I asked about the 9070xt GPU, the guy behind the counter came back with a list of CPUs. They had fuckall of nothing. Going on the site, the option for Backorder was available and I'm almost certain my bro got himself and I got the last 2 XTs. I won't see it until April, and as we're in Canada I'm concerned they'll raise the price between now and then.

I saw the images of hundreds in stock, but those would certainly be limited to the largest population centers/biggest outlets.
