Discussion AMD SoC Halo series GPU discussion

[MS_AT]

Text generation seems sadly slow

More or less as expected given the theoretical BW, but I would expect 10-15% more should be possible to achieve, to be close to 80% of theoretical BW.

It will be also better with recent Qwen MOE models, where you can get 20 tk/s from ddr5 2ch at 6000MT/s on CPU, with Q6.

we finally got numbers and Halo is good in a 14" laptop. Sidenote - The 275HX is just sad of a product.


That being said HP screwed up big time in the battery life test. Battery life sucks, esp video playback.

Has anybody seen a review of HP ZBook G1a with *only* 1920*1200 panel? I assume battery life would be much better than with OLED. 2.8K OLED panel is not necessary in my (customer's) use case.

Regarding halo memory allocation, is it dynamic or preallocated in bios?

I am looking for a halo laptop for customer who uses Archicad. For example if we choose 64GB model does GPU "take" 16GB and 48GB is left for OS part? Archicad runs fine on discrete 8GB consumer cards (both AMD & NVIDIA).

While OLEDs will diminish laptop battery life somewhat, the impact of this choice would be minor relative to the base numbers. The very low video playback numbers in the review above suggest a platform power management issue or a driver issue. We know Stric Halo can do much better based on reviews of the Asus Flow Z13.

To give you a sense of scale, here's a 120Hz hi-res OLED equipped laptop that still boasts 10 hours of web surfing and 19 hours of video playback.

Notebook check has one of the elitebook x g1a which has strix point instead of halo but is otherwise identical.

I think Windows handles this automatically. You don't have to set the graphics memory to a high amount, such as 16GB. You can just leave it as default (~128 MB) and windows will allocate what it needs.

It may be different in running AI models on it, where you probably have to allocate the memory manually.

Unfortunately windows doesn’t do this automatically.

There is something called Dynamic Video Memory Technology (DVMT)

Not Windows but I think it is the GPU driver that handles it. At least on the 5825U laptop I tested, the GPU was able to allocate up to 8GB out of available 16GB RAM and it was dynamic.

You can set the minimum and variable amounts in the AMD driver app. Don't know if this is a brand new option for Halo or applies to all newer APUs, my old 5600U laptop does not have this option in Adrenaline (can be configured in UEFI though).



In your particular case you can either set dedicated memory to 4GB (this might be the default) and allow dynamic allocation of another 4GB, or you can set 8GB dedicated from the start.
