MagyarDell Latitude 15 9520 2-in-1 vs. Latitude 9510 2-in-1: Newer isn't always better
The Latitude 9520 2-in-1 swaps out the 10th gen Intel CPU on the Latitude 9510 2-in-1 for newer 11th gen options while keeping the chassis identical. Thus, we recommend checking out our existing review on the Latitude 9510 2-in-1 to learn more about our thoughts on the chassis, keyboard, and other physical features of the system. This review will focus on the differences between the two models including what users can expect in terms of performance.
Our test unit is a higher-end configuration with the vPro-enabled Core i7-1185G7 CPU, Iris Xe 96 EUs GPU, 16 GB RAM, and 512 GB NVMe SSD for approximately $2800 USD. Lesser SKUs with the Core i5-1145G7 CPU and half the storage capacity are available for around $2300. Note that all 2-in-1 SKUs come with the same 15-inch FHD panel with proximity sensor and electronic shutter. Alternatively, users can also purchase the Latitude 9520 clamshell if the 2-in-1 form factor is undesirable.
The Latitude 9520 2-in-1 competes with other high-end business convertibles like the MSI Summit E13 Flip, Microsoft Surface Book, HP EliteBook x360 1040 G7, or the Lenovo ThinkPad x13 Yoga.

Case
Though the chassis is identical to last year's model, the hinges on our Latitude 9520 2-in-1 test unit would feel weaker at angles between 60 and 90 degrees. Ideally, hinge rigidity should be uniform across all angles. We recommend checking the hinges after purchasing for any abnormalities.
Connectivity
The Thunderbolt 3 ports on the Latitude 9510 have been upgraded to Thunderbolt 4 on our Latitude 9520. To most users, however, the upgrade will be of essentially no significance unless if you plan on using external GPUs. All other ports are otherwise identical between the two models.

Dell uses the same AU Optronics B150HAN IPS panel between both the Latitude 9510 2-in-1 and 9520 2-in-1 for a similar visual experience between them. There are unfortunately no new panel options for the 9520 2-in-1. 4K or OLED options would be great to see on future Latitude 2-in-1 revisions.

Performance
Testing Conditions
Our system was set to Windows 'Best Performance' mode and with Dell Power Manager set to Ultra Performance prior to running any benchmarks below for the highest possible scores. Users should also become familiar with the pre-installed Dell Optimizer software which includes additional settings for audio, network, and the proximity sensor for hands-free login.
Processor
Multi-thread CPU performance is a mixed bag since the Core i7-1185G7 has two fewer cores than on last year's Core i7-10810U for a downgrade of approximately 25 to 35 percent. The delta is wider than expected since the i7-1185G7 in our Latitude 9520 2-in-1 is performing at least 15 to 20 percent slower than most other laptops using the exact same CPU. The Core i7-1185G7 CPU in the MSI Stealth 15M, for example, can offer up to 50 percent faster multi-thread performance than our Dell.
Single-thread performance is thankfully where it should be relative to the average Core i7-1185G7. Users can expect around 30 percent faster performance than the Core i7-10810U in this regard.

DPC Latency
LatencyMon shows minor DPC latency issues related to ACPI.sys when opening multiple browser tabs of our homepage. Nonetheless, it is still an improvement compared to what we observed on last year's model.
4K video playback at 60 FPS remains perfect with no dropped frames and a more efficient GPU utilization than with the UHD Graphics 620.

Storage Devices
Our test unit uses the same PCIe3 x4 Toshiba KBG40ZNS512G NVMe M.2 2230 SSD as found on the Latitude 9510 2-in-1. Dell is currently offering no PCIe4 options even though the Intel chipset should theoretically be able to support such SSDs. The lack of a heat spreader, however, will mean that any PCIe4 SSDs would likely throttle after a short period, anyway.

GPU Performance
3DMark scores show the Iris Xe 96 EUs in our Latitude 9520 2-in-1 performing well relative to other Iris Xe laptops in our database. The devil is in the details, however, as real-world gaming performance is poor due to the unusually wide fluctuating frame rates. For example, frame rates would constantly jump between 40 FPS and 90 FPS when simply idling on Witcher 3 at its lowest settings whereas the Iris Xe-powered MSI Summit B15 would run much more stably without any of the sharp FPS drops. Thus, while our Latitude 9520 2-in-1 Iris Xe is indubitably faster than the UHD Graphics 620 on last year's Latitude 9510 2-in-1, it could have definitely been more stable in terms of performance over time.

Emissions
System Noise
The internal fan is silent at 24.1 dN(A) when idling or web browsing on the Balanced or Optimized mode or lower. It may occasionally jump to 25.8 dB(A), but this will be unnoticeable in most environments. Users can reach the maximum fan noise of just under 40 dB(A) when running higher loads like games.
Fan noise will pulse more frequently if set to High Performance mode when browsing or video streaming. Thus, be sure to set the power profile appropriately if fan noise is a concern.

Stress Test
The unsteady performance when running Witcher 3 as mentioned above can be attributed to the unsteady clock rates when the CPU and GPU are under simultaneous load. GPU clock rates would flip between 500 MHz and 1200 MHz when running the game whereas most other Iris Xe laptops would remain stable at fixed clock rates for steadier performance. The MSI Summit B15, for example, would have a steady GPU clock rate of 1300 MHz when under the same gaming conditions as our Dell. This undesirable GPU behavior makes the Latitude 9520 2-in-1 a comparatively poorer choice for graphics intensive tasks.
If stressing only the CPU via Prime95, clock rates would boost to 3.2 GHz for just the first few seconds at a core temperature of 98 C. Thereafter, clock rates would fall to to the low 2 GHz range in order to maintain a cooler core temperature of around 75 C. Multi-thread long-term PL1 and short-term PL2 power limits sit at 22 W and 45 W, respectively, when the system is on High Performance mode.
Running on battery power will not limit performance as 3DMark 11 scores are nearly identical between mains and batteries.

Energy Management
Power Consumption
Running 3DMark 06 would consume just 44 W on our Latitude 9520 2-in-1 compared to 46 W on the Latitude 9510 2-in-1 despite the massive increase in graphics performance on the newer model. Thus, owners are getting an average 3x increase in GPU performance under the same power envelope. The year-over-year performance-per-watt increase cannot be understated.
Unfortunately, the unsteady GPU performance mentioned above is reflected by the unsteady power consumption rates as shown by our graphs below. When running Witcher 3 to represent gaming loads, consumption would range between 21 W to 40 W whereas it would remain steady at just 34 W on the HP EliteBook 850 G8 equipped with the similar Core i7-1165G7 CPU.
We're able to record a maximum draw of 88.7 W from the small (~13 x 6.6 x 2.3 cm) 90 W AC adapter. The system is unable to maintain this rate for longer than just a few seconds due to thermal limitations.

Battery Life
Runtimes are a few hours shorter than what we recorded on last year's model despite the identical 88 Wh batteries between them. Even so, 14+ hours of real-world WLAN use is still nothing to scoff at and well above average for the size category.
Dell offers SKUs with smaller 46 Wh batteries for users who don't mind sacrificing battery life for a lighter unit.

Pros
Cons
Verdict
The Latitude 9520 2-in-1 offers significant performance advantages over the Latitude 9510 2-in-1 on paper. The older UHD Graphics 620 has been made obsolete now that Iris Xe is becoming more common. In practice, however, there are caveats that potential buyers shouldn't ignore.
Firstly, the Iris Xe GPU in the new Latitude runs at cycling clock rates resulting in cycling frame rates when gaming or unsteady performance when running GPU-intensive tasks. Frame rates would cycle by such extremes that some applications where steady frame rates are vital would become almost unplayable. We recommend looking at other Tiger Lake-U laptops like the MSI Summit E13 Flip or HP EliteBook 840 Aero G8 if steadier and more reliable GPU performance is desirable.
The main selling point of the Latitude 9520 2-in-1 over the 9510 2-in-1 is its significantly faster integrated graphics performance. However, the unusually unsteady graphics performance on the newer model can be a turn off for many interested buyers.
Secondly, multi-thread CPU performance from our Core i7-1185G7 CPU is slower when compared to the older Core i7-10810U on the Latitude 9510 2-in-1. Though this disadvantage isn't unique to Dell PCs, the i7-1185G7 in the Latitude 9520 2-in-1 is running slower than on many other laptops with the same processor. Thus, the multi-thread performance deficit is amplified on the Dell.
Reasons for choosing the Latitude 9520 2-in-1 over the 9510 2-in-1 are smaller than we would like especially since the newer model offers nothing new in terms of display quality, webcam quality, or battery life. Hopefully the uneven GPU performance can be addressed with a future update.
Price and Availability
Most major retailers like Amazon, Walmart, and Newegg have the Latitude 9520 2-in-1 in stock in various configurations. Users can also purchase directly from Dell starting at $2800 USD for the Core i5 version.
