技术评测者Jeff Geerling近日对搭载Intel Core 5 320芯片的Dell XPS 13与Apple MacBook进行了性能和能效对比测试[1]。测试采用HPL Linpack基准方法[1]，结果显示Dell XPS 13在单位能耗性能上表现出色。
Dell XPS 13在测试中实现了127.91 Gflops的计算性能，耗电功率为20.6W，综合能效达到6.21 Gflops/W[1]。相比之下，MacBook在相同基准下达到57.012 Gflops的性能，耗电10.6W，能效为5.38 Gflops/W[1]。Intel这款x86芯片的能效表现超越了MacBook，并接近M4 Mac Mini的7.57 Gflops/W[1]。这一结果表明，Intel在x86架构平台上的能效水平正在缩小与基于ARM架构苹果芯片之间的差距[1]。
Technology reviewer Jeff Geerling conducted a comparative benchmark analysis of Intel and ARM-based systems, testing the Dell XPS 13 equipped with an Intel Core 5 320 processor against Apple's MacBook using the HPL Linpack standard from the Top500 benchmark suite [1]. The results revealed that the Dell XPS 13 achieved 6.21 gigaflops per watt (Gflops/W), outperforming the MacBook's 5.38 Gflops/W, which delivered 57.012 gigaflops at 10.6 watts of power consumption [1]. The Intel-based system consumed 20.6 watts to reach 127.91 gigaflops, demonstrating improved energy efficiency on the x86 architecture [1].
The Dell XPS 13's performance positioned it near the M4 Mac Mini's 7.57 Gflops/W efficiency rating while surpassing the M4 and M3 Mac Studio configurations [1]. These findings suggest that Intel is progressively reducing the traditional performance-per-watt advantage that ARM processors have historically maintained [1].
