Verdict — Leaner And Lighter With Some Compromises
The Dell 16 Plus 2-in-1 is both an upgrade and a downgrade over last year's Inspiron 16 7640 2-in-1. It's slightly lighter and thinner with much faster graphics performance than before which may benefit travelers, casual gamers, or GPU-accelerated tasks.
Some of the year-over-year changes may not be for everyone. The move from Core Ultra-H to Core Ultra-V processors in particular has reduced raw processing power by quite the margin. Meanwhile, the rearranged ports are arguably for the worse as both USB-C ports are now packed closely together which affects docking ergonomics. Battery capacity has also been cut significantly to the point where battery life is shorter than on the Inspiron 16 7640 2-in-1 even though the older system ships with the faster Core Ultra-H CPU.
Balanced users who can appreciate the integrated numpad and relatively fast iGPU may prefer the newer Dell 16 Plus 2-in-1. Otherwise, power users who rely on raw CPU horsepower may still want the older Inspiron 16 7640 2-in-1 especially since both models share the exact same panels for an identical viewing experience.
Pros
Cons
Price and Availability
Dell is now shipping the Dell 16 Plus 2-in-1 starting at $950 with an IPS panel or $1500 with mini-LED.
The Dell 16 Plus 2-in-1 is the convertible version of the Dell 16 Plus clamshell and the direct successor to the 2024 Inspiron 16 7640 2-in-1. It represents the start of a new generation of mainstream laptops designed to replace the outgoing Inspiron naming convention of old.
Our test unit is a middle configuration with the Core Ultra 7 256V CPU and 2.5K 90 Hz Mini-LED touchscreen for approximately 1400 USD. Lower-end SKUs may come with a more traditional FHD IPS touchscreen while higher-end SKUs ship with the Core Ultra 9 288V instead.
Competitors to the Dell 16 Plus 2-in-1 include other 16-inch multimedia convertibles like the HP Envy x360 2-in-1 16, Lenovo Yoga 7 2-in-1 16ILL10, or Samsung Galaxy Book5 Pro 360.

Specifications
Case
The case iterates on the Inspiron 16 7640 2-in-1 while using similar aluminum and plastic materials for that familiar "Inspiron" feel and quality. Dimensions and weight are subsequently almost identical between the two models save for the ever-so-slightly thinner profile of the newer model.
Connectivity
Port options are identical to last year's Inspiron albeit with one important difference: the omission of an integrated SD card reader. The two USB-C ports have also been rearranged arguably for the worse as you can no longer charge the system along its right edge.
Communication
Webcam
A 2 MP webcam comes standard with physical shutter and no IR.

Sustainability
Dell does not explicit label any recycled materials used during the manufacturing of the Dell 16 Plus 2-in-1. The packaging uses no plastic for easier recycling.
Accessories And Warranty
The retail box includes the AC adapter and paperwork. The usual one-year manufacturer warranty applies if purchased in the US.
Input Devices
Keyboard And Touchpad
The keyboard and clickpad are 1:1 with the Dell 16 Plus clamshell for an identical experience. It's an upgrade in terms of producitivty over last year's Inspiron 16 7640 2-in-1 which favored large speaker grilles over an integrated numpad.
Display
The system utilizes the exact same AU Optronics B160QAT mini-LED panel as found on last year's Inspiron 16 7640 2-in-1 for the same viewing experience between the two models. Mini-LED panels are usually brighter and with deeper colors than most IPS panels for better HDR support, but they may exhibit halo effects and weaker black levels that aren't otherwise present on OLED panels.
Maximum brightness can reach 642 nits when HDR is enabled or 432 nits when on the default SDR mode.

Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 2807 Hz Amplitude: 50 % | ≤ 100 % brightness setting | |
The display backlight flickers at 2807 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 2807 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8350 (minimum: 5 - maximum: 343500) Hz was measured. |
Performance
Testing Conditions
We set Dell Optimizer to Performance mode prior to running the benchmarks below.
Processor
The Core Ultra 7 256V emphasizes performance-per-watt over raw performance and so it offers very little over the last generation Core Ultra 7 155U or even the Core i7-1355U if users don't utilize the integrated NPU. Perhaps most notably, upgrading to the more expensive Core Ultra 9 288V configuration is only expected to boost performance by a measly 5 percent at best based on our time with the Acer Swift 16 AI. The Core Ultra 7 155H in last year's Inspiron 16 7640 2-in-1 is roughly 1.5x faster than our Core Ultra 256V.

Not only is the Samsung BM9C1 PCIe4 NVMe SSD slower than the Micron 2550 in last year's model, it tends to throttle as well. Transfer rates would cycle between 3400 MB/s and 4700 MB/s compared to the steadier ~5000 MB/s on the Inspiron 16 7640 2-in-1 when running our DiskSpd loop test as shown by the graph below.

GPU Performance
Whereas the Core Ultra 7 258V is slower than the Core Ultra 7 255H in last year's Inspiron when it comes to processor performance, the opposite is true when comparing the Arc 140V to the Arc 8. The Dell 16 Plus 2-in-1 is able to run demanding games like Final Fantasy XV or Cyberpunk 2077 anywhere between 35 to 50 percent faster despite the slower processor performance.

Emissions
System Noise
Fan noise floor and ceiling are essentially unchanged from what we observed on last year's model despite the CPU and iGPU performance differences. However, the fan in the Dell 16 Plus 2-in-1 is more slow to react to onscreen loads and so the system can remain quieter for longer before higher RPMs are needed.

Temperature
Surface temperature hot spots can reach just over 44 C and 39 C on the keyboard deck and bottom panel, respectively, which is just slightly warmer than what we recorded on the competing Lenovo Yoga 7 2-in-1 16ILL10.
(±) The maximum temperature on the upper side is 44 °C / 111 F, compared to the average of 35.4 °C / 96 F, ranging from 19.6 to 60 °C for the class Convertible.
(+) The bottom heats up to a maximum of 39.4 °C / 103 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 28.7 °C / 84 F, compared to the device average of 30.3 °C / 87 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 26.8 °C / 80.2 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.9 °C / 82.2 F (+1.1 °C / 2 F).

Stress Test
When initiating Prime95 stress, the CPU would boost to 3.4 GHz and 38 W until hitting 93 C several seconds later. Thereafter, performance would drop to 2.5 GHz and 22 W in order to maintain a cooler core temperature of 72 C. This is cooler by almost 15 C when compared to the Inspiron 16 7640 2-in-1 under similar conditions, but keep in mind that the Dell 16 Plus 2-in-1 ships with a slower processor as well.
Core temperature when running Cyberpunk 2077 to represent typical gaming loads would also be significantly cooler than on last year's Inspiron while offering better gaming performance.

Energy Management
Power Consumption
Consumption when idling is similar to what we recorded on last year's Inspiron 16 7640 2-in-1 since they share more than a few similar components. When running more demanding loads, however, the Dell 16 Plus 2-in-1 requires much less power since the Core Ultra 7 258V is slower and more efficient than the Core Ultra 7 155H.
We're able to measure a maximum consumption of 67 W from the small (~11 x 5 x 2.8 cm) 65 W USB-C AC adapter.
