Why do people care so much about single core performance? We are all professionals here and I bet most of our workloads are multi core. I get that these new arm chips from Apple and Qualcomm are great at one thing at a time, but for professional workloads high end x64 chips still cannot be beaten on the desktop.
What x86 chips have the same or higher number of cores in the form factors that these chips are available in and are also more performant? Strix Halo is 16 cores. Intel Core Ultra 9 285HX is 24. Apple is 18. Qualcomm is something similar too but I can’t recall. NVIDIA is 20. Until you get to threadripper/epyc or Xeon territories (completely different form factors and TDPs) the arm chips are ahead on both power and pe…
Nvidia Spark has 10 mid cores and 10 fake cores. Probably all the others are faster.

FYI it existed long before that. Shared memory between CPU and iGPU has been a thing for a long time.
Zero-copy shared memory?

#314The Unified Memory pool is what will continue to be the “game changer” in systems architecture, especially outside of data centers. The reality is even cutting edge games and consumer workloads don’t actually take full use of the PCIe bandwidth of the GPU or the bandwidth of its GDDR memory. Even local AI use cases don’t substantially or meaningfully benefit from faster memory, at least to average consumers. A unifie…
And conveniently, by making your machine non upgradeable, it allows the manufacturer to enforce market segmentation / charge a huge premium for small RAM upgrade ( a la Apple)
Is that required or just a choice Apple made?

AMD Fusion knocking from 2010.
Re: Nvidia is proposing a beast of a CPU system for Windows PCs
#316How much is this supposed to cost, fully populated with 128GB of RAM? How much would this laptop cost? It's not that the NVidia chip has that much RAM built in, after all. It's that it can address that much. RAM is sold separately.
$4,000-5,000

Are there no PCIe standards that are sufficient to support both use cases?
What happened to PCIe 8 and CXL?

What do you mean by required? Apple's prices are notoriously disconnected from the cost of manufacturing.

yes, here is 2013 AMD presentation of the topic as example: https://events.csdn.net/AMD/GPUSat%20-%20hUMA_june-public.pd... see slide 14 especially

I hope a family-level AI appliance is a thing later. Local non-cloud assistant that lives in the house, families interact via voice or phones or whatever. Knows the contextual family stuff you need, etc.
We didn't get people buying family-level file servers for the family photo gallery and documents at any real scale, so i doubt we'll see similar for AI especially when the cost is that much higher for GPUs vs an SBC machine.
because nas hardware and software suck and everything else was a poorly executed subscription product...i think one was called helm, another was by early twitter alumni. imagine a home device that manages and maintains itself and is a joy to interact with.
