We have not been able to verify any of these claims in the real world, but we've received more and more demos of how powerful the 8cx should be. Here in Taiwan, Qualcomm once again presented a reference design notebook, in which the "extreme" chipset transfers streaming to two 4K displays in addition to its own screen. (To be clear, it was not the Project Limitless device that ran this demo.)
When the CPU was announced in Hawaii, we saw a similar setup. This time the system seems to be more stable. In Photoshop CC, I could adjust the hue and saturation of an image, while the reference laptop ran Edge, PowerPoint, Excel, and a video on the external screens. The reference laptop was a bit late in applying the changes, but otherwise stayed the same.
The Project Limitless 5G laptop was deployed in a separate station demonstrating its connection to a dedicated sub-6GHz network. Since the real speeds can not yet be tested, we could not do much here to test the capabilities of Limitless.
According to the previewer system settings, the Snapdragon 8cx CPU ran at 2.8GHz and had about 16GB of RAM, which together should provide reliable multitasking performance.
Qualcomm also provided reference benchmarks to demonstrate how the Snapdragon 8cx sets itself apart from its main competitor, the Intel Core i5-8250U. Using the recently announced PCMark 10 Applications benchmark on similar systems, Qualcomm's results showed that the 8cx surpasses the i5 on apps like Microsoft Edge and Word. Intel, however, had the upper hand over Excel and PowerPoint.
