This is such nonsense

Quote from: Tnep on December 21, 2022, 06:38:03So, now that AMD has responded to these accusations and multiple places have put these claims to the test only to prove that it's not true are you guys going to edit or change this article in some way or just let it sit around so that people that happen to come across it are incorrectly informed?

The latter, of course. I hate to say it, but NBC continues to lose more and more credibility and is little more than an echo chamber for other sites' news (and I use that term somewhat loosely) with little actual journalism of their own. I've been coming here regularly for a couple years now, but I'm starting to look elsewhere for tech-related news and reviews.

So, now that AMD has responded to these accusations and multiple places have put these claims to the test only to prove that it's not true are you guys going to edit or change this article in some way or just let it sit around so that people that happen to come across it are incorrectly informed?

Some Twitter nonsense as always

Quote from: Chiccozman on December 15, 2022, 17:01:01You guys are kidding right? AMD releasing a buggy gpu? Come on, this can't be true.

Idiots on the internet taking speculation from idiots that don't know what they're talking about as fact? Come on, this can't be true.

"Despite voltage being lower than expected (barely touches 1V), the cards somehow draw more than 400 amps."

Someone needs to go back to basic electronics class. The N31 chip itself drawing 400A is no big deal, why do you think the VRM section of today's cards often have a dozen or so 70-90A "power stages"? That doesn't mean the card is drawing 400A from the PSU, as the supply is at 12V not 1V, so more like 30-35A (which is easily supplied by pretty much ANY modern PSU's 12V "rails").

That's also complete BS the launch window for N31 was missed by a year.  6 months BEFORE 6950xt, and barely a year after N21? Come on....

Quote from: Tingle on December 16, 2022, 01:32:50They just need to cut £200 off the XTX price.

Why?  The card is already the best price/performance for raw fps of all time.  And the 7900xt is probably #2 (or #3 behind 4090).  I think you may be either whining or selfish, to say such a thing.

Yet another sensationalized and dubious anti-AMD article by notebookcheck.  I swear these guys are taking a paycheck from Nvidia.

Quote from: vertigo on December 16, 2022, 16:06:52You don't look at amps on the draw side and directly correlate with amps on the supply side. You have to use watts for that (which is why, yes, stating watts vs amps in the article would have been better). A PSU supplies power in different voltages, mainly 3.3V, 5V, and 12V. All it has to do is supply e.g. 25A @ 12V (300W), 15A @ 5V (75W), and 7.5A @ 3.3V (24.75W) to provide 400W. The GPU then uses those different voltages in different ways, e.g. the 12V will run the fans and the different voltages will be stepped down to lower voltages for various other things, and when that happens, the amperage increases. If it's stepped down to 1V, then 400W would indeed be 400A. So it's not as crazy as it sounds. That said, it does seem unlikely, since much of the voltage would be kept at 12V for the fans, so to use 400A would require well over 400W. Because of that, I retract my previous statement and agree it likely is a typo. Even if it does somehow work out to 400A and isn't a typo, it's very poor writing to describe it that way, since it's not conventional and it makes it seem much worse.

davidbepo mentions that voltage actually never hits 1 V and this seems to be consistent with the reviews reporting 0.1 V in idle state and a maximum of 0.9 in some games but an average of 0.7 V. That's why I said "barely touches 1 V."

If power draw is really 1v then 400 watts/ 1 volt= 400 amps. But most likely it's misreporting cause no way a psu can provide 400 amps, this entire article has issues...

 Not that any of this matters since scalpers have already bought every new gpu in stock.

Yes, 200 Amps is typical service for a US house, with some older homes having 100 Amp service or less.

If the card consumed 200 Amps, it would promptly explode. It's pretty clear the correct answer is 400 Watts. I'm sure they'll fix this typo.

You guys need to learn at least a little about electricity before making statements like this. Power (Watts) = Current (Amps) X Voltage (Volts). At 1V, 400W=400A. That does NOT mean it's pulling 200A from the outlet. Power draw is wattage, not amperage, and it's drawing 400A @ 1V which, again, is 400W. A typical circuit is 15 or 20A, which is at 110-120V (US, different elsewhere), so 1725-2300W @115V. This is far above the 400W draw of this card. So no, it's not a typo, and there's nothing for them to fix. It's easy as P=IE.
