Is this similar to Macbook M series chip with shared memory ? Will this allow intel chips to run local llms efficiently ?
- dagmx 2y agoIn theory, that’s how Intel already is but the memory accessible to the GPU is capped at conservative values . The other issue is that traditionally the integrated GPU has been quite anaemic.

- Dylan16807 2y agoMicrosoft's local copilot requirements are 16GB of memory so it's plenty for that.

- AnthonyMouse 2y ago> the Lunar Lake SoC platform also includes up to 32 GB of LPDDR5X memory on the chip package itself. This is arranged as a pair of 64-bit memory chips, offering a total 128-bit memory interface. As with other vendors using on-package memory, this change means that users can't just upgrade DRAM at-will, and the memory configurations for Lunar Lake will ultimately be determined by what SKUs Intel opts to ship. In other words, even though it's on-package, the width of the memory interface is the same as previous generations. They also exclude upgradability unnecessarily, because even with on-package memory you can still support adding memory through slots. For example, the Xeons with on-package HBM allow this. This decision by Intel seems specifically designed to screw the customer by forcing them to buy a new CPU (or computer) in order to upgrade the memory, without even providing the countervailing benefit that Apple gets from doing it that way. (Note that Apple too unnecessarily prevents adding memory at the traditional level of performance. Cache hierarchies are a thing, if you're not trying to screw the customer.)
- gjsman-1000 2y agoWhat part of “uses up to 40% less energy” due to lower voltage requirements did you not read?
- AnthonyMouse 2y agoThere is no way that you can get a 40% reduction in total CPU power consumption, much less system power consumption, just by lowering the voltage of the memory -- the entire contribution of the memory is a tiny fraction of the system's power budget. Reducing power consumption by an imperceptibly small fraction of a fraction of a percent is just an excuse.
