Regarding the Snapdragon X Elite processor that was recently demonstrated at the Snapdragon Tech Summit 2023 eventTwo different reference designsRegarding the TDP indicated on the Snapdragon X Elite processor, Qualocm later clarified that the 23W and 80W TDPs mentioned at the time did not refer to the TDP of the processor itself, but rather to the TDP of the entire reference design. This means that OEMs adopting the Snapdragon X Elite processor in the future will have greater flexibility in product design.
Qualcomm stated that it will not currently disclose the power consumption performance of the Snapdragon X Elite under specific workloads. The 2023W and 23W TDP figures announced at the Snapdragon Tech Summit 80 event actually refer to the TDP of the entire reference design itself, not the TDP of the Snapdragon X Elite processor.
Qualcomm further stated that the Snapdragon X Elite processor's power consumption for single-threaded workloads will be significantly lower than the device's thermal design power (TDP). This means that even when used with a reference design with a 23W TDP or a reference design with an 80W TDP, the processor will actually consume less power.
This means the Snapdragon X Elite processor's actual power consumption may be lower than expected. It can be used in reference designs with either a 23W or 80W thermal design power consumption, depending on product design requirements. This allows for different performance outputs, echoing Qualcomm's previous emphasis on the design flexibility of the Snapdragon X Elite processor when used in actual products.
Regarding performance and power consumption calculations, Qualcomm believes that thermal design power consumption should focus on the comprehensive results of the operation of the entire platform components, including the processor and memory. This measurement method is more consistent with the actual performance corresponding to real workloads, and different power consumption performance will vary depending on the workload.
It is not clear whether Qualcomm's explanation this time is aimed at Apple's earlier announcement.M3 series processorsWhen comparing it with a competitor's 12-core laptop processor, it emphasized that it only requires a quarter of the power consumption to achieve the same CPU computing performance, and only one-fifth of the power consumption to achieve the same GPU display performance.
Compared to conventional descriptions of processor performance, which typically focus on the processor's thermal design power (TDP), Qualcomm emphasizes that TDP should take into account the performance of computing components, including the processor and memory, rather than just the processor itself. Therefore, it emphasizes that the TDP corresponding to the reference design will be used for evaluation. This is obviously different from the current labeling method used by other processor manufacturers.
