sm_1024··on Silicon Valley finally has a big electronics retailer again: Micro Center opens
Interesting part is they have actually been open for a week now. They did a quiet opening on the 25th and it was still busy that day
sm_1024··on AMD's Strix Point: Zen 5 Hits Mobile
I see what's going on, they have two HX370 laptops:

  Laptop  MC score  Avg Power
     P16      1213      113 W
     S16       921       29 W
  M3 Pro      1059    (30 W?)
They don't have M3 Pro power numbers, but I assume it is somewhere around 30W, seems like S16 has similar power efficiency as HX 370 at 30 W.

Any more power, and the CPU is much less power efficient, 300% increase in power for 30% increase in performance.

I think the OC might have mis-read the power numbers, 110 W is well into desktop CPU power range. Here is a excerpt from Anand Tech:

> In our peak power test, the Ryzen AI 9 HX 370 ramped up and peaked at 33 W.

119W for hx370 looks extremely sus, seems to me more like the system level power consumption and not CPU-only.

According to phoronix [1,2], in their blender CPU test, they measured a peak of 33W.

Here max power numbers from some other tests that I know are multi-threaded:

--

Linux 6.8 Compilation: 33.13 W

LLVM Compilation: 33.25 W

--

If I plug in 33W into your equation, that would give us score of HX 370: 104 PPA

This supports the HX 370 being pretty power efficient, although still not as power efficient as M3.

That is fair, I was taught that decoders for x86 are less efficient and more power hungry than RISC ISAs because of their variable length instructions.

I remember being told (and it might be wrong) that ARM can decode multiple instructions in parallel because the CPU knows where the next instruction starts, but for x86, you'd have to decode the instructions in order.

sm_1024··on AMD's Strix Point: Zen 5 Hits Mobile
I have heard that part of the reason for little coverage of ryzen mobile CPUs is their limited availability as AMD was focussing on using the fab capacity for server chips.
sm_1024··on AMD's Strix Point: Zen 5 Hits Mobile
IMO, the most interesting thing about this line is the battery life---within an hour of MBP3 and within 2 hours of Asus's Qualcomm. Making it comparable to ARM architectures.

Which is a little surprising because ARM is commonly believed to be much more power efficient than x86.

sm_1024··on AMD Threw the Match but Won Anyway – Strix Point Ryzen AI 300 Review [video]
These are interesting results and make a strong case for AMD over Qualcomm, especially in battery life:

  ASUS S16 (Qualcomm):    13h 39m  
  Apple MacBook Pro (M3): 12h 35m  
  ASUS S16 (AMD):         11h 10m  
  ASUS S15 (Intel):        9h 15m  
Cinebench Multicore:

  ASUS S16 (Qualcomm):   1,138  
  ASUS S16 (AMD):          997  
  Apple MacBook Pro (M3):  716  
Cinebench Single core:

  Apple MacBook Pro (M3): 141  
  ASUS S16 (AMD):         113  
  ASUS S16 (Qualcomm):    108

They do make 10 TB+ SSDs:

Infact, Kioxia's enterprise line goes up to 30 TB/drive.

sm_1024··on Gaudi 2 – An AI Accelerator Card with 96GB of HBM2E Memory
I'm guessing H100 has 2x host energy overhead for connecting those GPUs? That might offset some of the perf/W benefits of nvidia's offering.

sm_1024··on Mark Zuckerberg on Apple’s Vision Pro headset
Modern Android processors are pretty competitive with iPhone's silicon:

S23, 1.4k (Single core), 4.8k (Multi core), 79.3 (3d mark/GPU)

14 pro max, 1.8k (Single core), 5.3k (Multi core), 74 (3d mark/GPU)

Looks like gen2 is already on-par in multi-core and GPU perf. Single core still is 28% faster in iphone.

If you are using a US SIM card, e.g., all your traffic is tunneled to the US. That could be the reason.

I wonder how hard it would be to replace FUSE with userspace block driver. That seems to be focused on performance.

sm_1024··on Samsung considers moving to Bing as default search engine
I'd expect bloatware to be unnecessary software. To a user who is not familiar with google's offering, the bloat doesn't exist, they don't see two different softwares. Samsung phones don't have two messaging apps, gallery, or phone app

Not including google's version doesn't equate to bloat. In fact, the opposite is true.

sm_1024··on Samsung considers moving to Bing as default search engine
That hasn't been my experience at all. If anything, they are more userfriendly than other phones I have used. One thing in particular that is very nice is that everything is accessible on the larger screen sizes, action centers, call logs, messages, everything is designed to be accessible when holding your phone with one hand without having to awkwardly reach the top.
sm_1024··on Intel Foundry Services and Arm announce collaboration on SoC design
> While 243GB/s is massive, and overshadows any other design in the industry, it’s still quite far from the 409GB/s the chip is capable of. More importantly for the M1 Max, it’s only slightly higher than the 204GB/s limit of the M1 Pro, so from a CPU-only workload perspective, it doesn’t appear to make sense to get the Max if one is focused just on CPU bandwidth.

sm_1024··on Android 13’s new sideloading restriction of Accessibility APIs
This is an interesting take. I'd assume iOS could just be considered an OEM variant of a mobile OS. I switched to samsung, and its UX is pretty consistent.

> my OEM's variant of Android has annoying additions that aren't allowed to be disabled. I'm hoping that iOS will be at least a slightly calmer experience

Would android's additions still seem like annoyance if stock (and every variant) included those additions?

tbf, I think iOS is a pretty good OS (like most modern OSes).

The title is misleading, the GitHub issue doesn't actually point out any flaws in the codebase.
