Dell 16 Plus 2-in-1 trades away CPU performance in favor of faster graphics and quieter fan noise

Dell 16 Plus 2-in-1 has both advantages and disadvantages when compared to the Inspiron 16 7640 2-in-1 that it replaces (Image source: Dell)

The older Inspiron 16 7640 2-in-1 may be the better deal if processor performance is of utmost performance. Otherwise, the newer Dell 16 Plus 2-in-1 is the more efficient machine.

The Dell 16 Plus 2-in-1 is now widely available for purchase to replace last year's Inspiron 16 7640 2-in-1. While there are a handful of changes, the biggest is arguably the swap from a Core Ultra-H CPU to a Core Ultra-V one which impacts overall performance.

In terms of raw CPU performance, the Core Ultra 7 155H in last year's Inspiron can be over 1.5x faster than the Core Ultra 7 258V in the newer Dell 16 Plus 2-in-1 when it comes to multi-threaded loads. The delta can be quite significant for power users who might rely on the faster processor.

In terms of raw GPU performance, the opposite is true as the Arc 140V can be 1.3x to 1.5x faster than the Arc 8 when gaming. Not only is it faster, but it is significantly more power efficient as well for improved performance-per-watt, lower core temperatures, and quieter fan noise. Users who can benefit from a faster GPU may consequently prefer the newer Dell 16 Plus 2-in-1 over the older Inspiron 16 7640 2-in-1.

There are several other differences between the two models aside from the processor including the smaller battery and lack of a MicroSD reader on the newer model. We recommend checking out our full review on the Dell 16 Plus 2-in-1 for more benchmarks and details.
