Most AMDs still get 1.5-2 times the battery life

The only noticeable difference today is DLSS vs no DLSS. If you would use DLSS in the games you play, then go with the 4070. DLSS is just significantly better than FSR, at least at resolutions lower than 4k.
Also the 4070 has slightly better RT, but I don’t think most people care much about that.

In the future the 16GB VRAM of the 7800 XT might become an advantage, though the difference between 12 and 16 is not huge. And the 7800 XT is like 3-5% faster. Due to the higher memory bandwidth it will probably also age a little better.
So if you think you won’t use DLSS, definitely go with the 7800 XT.

This is assuming they are priced as they are right now (4070 is ~520 and 7800 XT is ~500). If the 4070 costs 15+% more money, just get the 7800 XT. Or spend a little more and go with the 7900 XT on sale (I’ve seen it go for $700, might go even lower on BF).

Hasn’t that been a feature on DDR4 as well? I think one of my kits has multiple profiles and the other one doesn’t. I’d assume higher end DDR5 kits have that as well.

MSI try it is pretty good, isn’t it? Makes it easy to see how far your RAM goes. Once you found the fastest one that is stable, you can use that as a baseline to OC further.

6000 runs in 1:1 mode (UCLK = 3000MHz)
7600 runs in 1:2 mode (UCLK = 1900MHz, slower than FCLK)

6000 CL36 is not the same as 7600 CL36 btw.
And of course you can run the 7600 CL36 kit at 6000 CL30

EXPO RAM is not faster than what you get with these mobile chips. The Z1 Extreme in the Legion Go for example uses 7500MHz LPDDR5X. Meanwhile desktop Ryzen CPUs struggle to do 6200-6400MHz.

8 TFLOPS on RDNA 3 is comparable to 4 TFLOPS on RDNA 2 (PS5).
The PS5 uses 36 compute units. The 780M has 12.
The PS5 has 450GB/s memory bandwidth. The 780M has around 100.

The 780M runs at significantly lower power and shares the memory bandwidth with the CPU, but even ignoring that it’s like 3-4x worse than a PS5.

Doesn’t make a difference. The issue is memory bandwidth, which is only around 100GB/s on DDR5. And it’s shared with the CPU, which makes it effectively even worse.

HUB or GN tested for this and didn’t find that

Why these games though?
If this works best in games that already get high fps in the first place, then I think this is probably not going to be that useful. Games like Starfield need more CPU performance, not friggin R6 or Metro Exodus, both of which get hundreds of fps anyway.

$280 4k 60Hz IPS 300 nits
Seems like a basic monitor. Probably overpriced. What do you want to use it for?

For gaming this is bad. 1440p 165Hz is better
For productivity I’d look for a 32" 4k monitor or 2 individual 27" 1440p monitors.
For photo editing I don’t know. Depends on how good the colors are.

M1 was 5nm. M3 is 3nm

Ryzen 5000 was 7nm. Ryzen 8000 is going to be 4nm (5nm family)

Intel did go from 14++++++ to “Intel 7”, so that was like 2 node jumps I think

Apple is making surprisingly small improvements, considering how people thought the M1 was like the second coming of Christ.

Looks like M1 to M3 is going to be roughly +20-30%. In the same time AMD is going from Ryzen 5000 to Ryzen 8000.
Even Intel got a significantly bigger improvement than that, going from the 10900K to the 14900K, and they had 1 trash generation and the 14900K is basically just a 13900K from 2022.

7800 XT is 475 USD in Germany (540€ after VAT)

The 7900 GRE actually got 10% SLOWER memory than the 7800 XT, but more cores. 5% faster and 0-10% more efficient than the 7800 XT.
At 720€ (635 USD) it’s very overpriced.

As a secondary machine just for browsing or spreadsheets and text documents, I wouldn’t mind soldered RAM, even if it’s only 16GB (or on ultra cheap <$300 laptops even 8GB).

If you expect to use the laptop as your main computer for many years, then no, soldered RAM is not a good idea (unless it has at least 32GB).
I wouldn’t worry about not being able to fix it, because RAM rarely goes bad. I’d worry about needing more RAM in the future and not being able to add more.
