AMD has unveiled its Ryzen 7040U mobile processors, two of which will be the first with the company's XDNA AI architecture.

Have a Framework preorder for a Ryzen 7 7840U. Q3 is pretty soon so hopefully it performs well!

As usual, AMD's timing isn't ideal. Meteor Lake will follow soon enough to dampen Phoenix' impact, not unlike how Raptor Lake stole much of the thunder from Ryzen 7000.

I hope AMD releases a Zen 4+ on TSMC N4, for AM5. I doubt it, but it would give them something to run against the Alder Lake Refresh.

AMD is making big promises on battery life, but isn't saying much. Its slides claim that it "invests heavily in leadership efficiency" and that the 7040U chips will have "smart power management designed to deliver the longest possible time unplugged." With no numbers to go off of, we'll have to see in our testing.

Probably because AMD pulled an Intel on Zen4 mobile. All 7040U CPUs, and those benchmarks, use a new default TDP: 28W.

These are basically Intel P-series now; 28W base and, what, maybe 50W-60W boost?

Why increase the default TDP by +86%, especially after a node shrink? Why follow Intel's terrible example? Why not at least set the default to 15W, so your OEMs + benchmarks, are aligned with what users want in ultra-portable laptops (e.g., more battery life, not more heat)?

What desktop GPU is this "8.6" tflops igpu equivalent to? Being FP16 I suppose it's half a RX6600 at around RX580 lvl?

If you stop to think about it the Nintendo Switch runs on a igpu equivalente to a GTX260 (!!), that's right a 2008 mainstream card, being just a portable PS3 (2006). It's a "17 years old console" right there, that's really insane. Being a 720p portable and having a dock that could add power a la SLI the switch could have been at least a PS4 lvl console back then, but no it was just that bad even at launch..... I didn't buy it, hoped it flopped. At that point Nintendo should have just became software focused and we would have a tears of the kingdom for the PS5 today, not for the "PS3"

Anyway.. and now what? Today it's possible to have around 4.2tflops on a igpu, its about a portable PS4 pro like the Z1 extrene. If Nintendo kept the same graphics of today but went 4k it would need at least 1.5tflops.... so to call it a "next gen" console and not a "switch pro" it really need a hardware AT LEAST of a 4tflops, but really will it? The Z1 is just a Switch pro.. the Z1 extrene is the real deal, but at $600.. means Nintendo will wait until next year so prices lower a bit?

You see.. that's why we are getting a rtx 4060 barely keeping up with a rtx 2060s from 4 years ago, because people just buy it. Had no one bough the Wii to begin with, knowing it was a really crap hardware, Nintendo would have stoped.itmright there. It's consumers fault really, people just buy whatever is new without "complaining*, aka not buying.

What desktop GPU is this "8.6" tflops igpu equivalent to? Being FP16 ...

Right. So, we should assume 4.3 fp32 TFLOPS, probably turbo.

Here are the official fp32 specs of some AMD GPUs in that ballpark:

Model	Launch Date (year-mo)	Launch Price	fp32 TFLOPS (base)	fp32 TFLOPS (turbo)	GDDR Bandwidth (GB/s)
HD 7970	2012-01	$500	4.10​	4.30​	288​
R9 290	2013-11	$400	4.85​		320​
R9 390	2015-06	$330	5.12​	​	384​
RX 570	2017-04	$170	4.78​	5.10​	224​
RX 5300 XT	2019-10	OEM	4.70​	5.20​	112​
RX 6500 XT	2022-01	$200	4.73​	5.77​	144​

I think we can safely say it must have some Infinity Cache, or else even that amount of compute power will largely go to waste.

For Nvidia cards, I'll just offer one point of comparison. The GTX 1660 launched in 2019-03 with 4.31 (5.03) fp32 TFLOPS and 192 GB/s of GDDR5 bandwidth.
