I mean they're clearly naming the SKU's over core counts and not frequency, which is not unusual. Intel and AMD do the same thing. Apple are the odd one out.

He said that while watching the Apple keynote and doing web work, the battery went from 90% to 75% in 2 hours. Very promising.
That normalizes to 13 hours? That's not even an increase over what my crappy 1250U laptop can do on a 51WHr battery while browsing the web and watching videos.

At max (likely 400) nits brightness with a 2.8-3K OLED display and speakers on?

Pretty great result in context lmao.

Efficiency and low idle power (for mobile battery life) aren’t like some far-off things that stand in isolation or are useless past a shoddy metric with a bird’s eye view like “got home with 40% left on my laggy Meteor Lake POS”

I know many don’t understand this or think no one cares, but have you seen the laptops doing 6-10H battery in mixed workloads (web browsing a decent test here) from AMD and Intel? The circumstances are, should we say, generous, and the user experience isn’t always top notch either, which is also exactly why Intel is moving the other direction to fix this now because competition won’t allow this anymore.


Getting the same performance more efficiently (and keeping idle down) gives you optionality. The real case isn’t “oh no, what will I do with another 10H of battery life” every time, but that you can run the same display brighter or with a higher resolution, have more responsiveness on tap, and still end up with great battery life and/or more leftover.

Speaker on but no OLED and it's at a normal brightness. Still eh. I was expecting better given they claim double the battery life for that device but it is merely matching my $700 XPS 13 9315 with a 1.5 year worn battery.

I guess we know why it hasn't appeared in any fanless devices yet.

Heh. We'll wait for full reviews to find out on June 18th.

Nvidia, Qualcomm, AMD, others are considering raising prices due to the tight supply of TSMC 3nm manufacturing technology for their AI chips, media report, adding 7 major chip designers in all (Intel, Apple, MediaTek, Google) are vying for TSMC’s 3nm capacity. The report says yield issues at Samsung have hampered its 3nm efforts, leaving customers with nowhere else to go but TSMC.
Rumor: Qualcomm will raise the price of its flagship Snapdragon 8 Gen 4 chips to over US$250 each due to higher production costs with TSMC’s 3nm process, media report, citing supply chain rumors, compared to the $200 for Snapdragon 8 Gen 3 chips last year, which were made on 5nm process. 3nm wafers are said to be around 25% more expensive than 5nm.
Oof.

8+ Gen1 = $120
8 Gen 2 = $160
8 Gen 3 = $200
8 Gen 4 = $250

Next time I travel to Mercury, which has a 1,408 hour day, or Venus, which has 5,832 hour day, I will make sure I take a Snapdragon laptop with me.

No Earth, we tend to go to sleep after ~16 hours, so any battery life past that is not relevant to Earth's inhabitants.
That’s not point. Multi-day battery life is a good thing.

Also what I am most interested is the standby and sleep on these ARM win machines.

Intel's next generation Panther Lake is rumoured to continue using on-package memory, that Lunar Lake is debuting.

Considering this, I think it makes sense for Qualcomm to also pursue on-package memory for X Elite G2.

Imagine a marble like this...

But with the Snapdragon logo inside...

Would make for nice fan merchandise

Until a laptop gets smarts and feet to drag itself to charger, or we have safe whole house / wide beam wireless chargers, multi day battery is a good thing.

It's not in my top 5 things in a laptop (responsiveness, screen, durability, convertible, value), but it's noice-to-have.

All else being equal (say, OEMs make same chassis but put different SOCs), or nearly equal, it's the tie breaker.

Not really. Lunar Lake is it's own swimlane and has no proper successor for now.

Panther Lake U is a semi-successor to Lunar Lake which inherits some of LNL ideas (Like 4P + 4LPE), but with a smaller GPU and targeting a cheaper price segment. But it doesn't use On-Package Memory afaik.

Edit: Just saw the shipping data that raises the possibility of PTL-U having PoP Memory SKUs. Interesting stuff.

Looks like a large and capable core. I wish there were some more details on branch prediction.
I'm not sure any company now gives any detail about branch prediction except some vague terms such as TAGE. I don't think even BTB sizes are known (but I might be wrong on this). This has become so tricky that it looks like black magic with a lots of secret sauce, some covered by patents, some not. Giving too many details, might break some competitive advantage and open the door to patent trolls.
