The display of the ZBook uses PWM at a particularly low frequency to adjust the brightness. The display of the HP ZBook 15 G3 isn't quite as bright either, although the difference isn't that great.
DELL PRECISION 490 DESKTOP WORKSTATION FULL
At 328 cd/m², the panel exceeds the promised value by a substantial margin and outperforms the Full HD IPS displays Lenovo uses for their much dimmer ThinkPads. All Precision 3520 displays are matte.ĭell promises a brightness of 300 cd/m² for the Full HD display. Our review notebook is equipped with a non-touch panel from BOE. Both versions of the Full HD display utilize IPS technology. The HD display, which the Latitude 5580 was equipped with, is based on TN technology and is - at least in our opinion - best avoided. Dell offers two different resolutions - HD (1366 x 768) and Full HD (1920 x 1080) - with the latter offered in both touch as well as non-touch versions. Potential buyers can chose from three different displays. Note: the pictures in this review are from the (identically constructed) Dell Latitude 5580. The sibling Precision 5520 ranks slightly better though especially as far as the uploads are concerned. The 2x2 module works as well as the predecessor did in the Precision 3510 and both the synthetic benchmark results as well as the real-world experience are quite decent. The WLAN module has changed slightly as well and the Precision 3520 now features the updated Kaby Lake Intel Wireless AC 8265 instead of the older AC 8260. The port types haven't really changed, although there is one major difference: the physical docking port on the bottom is now missing, which leaves Thunderbolt 3 or USB Type-C connected docks as the only expansion option. The SD card reader and one USB port moved from the right side to the left side the fan exhaust is now on the back. The predecessor had the SIM card slot and the VGA port on the back - the new version features them on the right side. The biggest difference is the location of the physical ports, which Dell revamped completely. The chassis looks identical to that of the predecessor, but it's a little lighter. An identically-equipped version of the workstation we configured on Dell's US site cost $2170 at the time of writing. The original review was conducted by our German colleagues. For a direct comparison, we are also going to check out the predecessor-GPU Quadro M600M in the ThinkPad P70. For comparison purposes, we are going to look at alternative workstation offerings like the ThinkPad P50, ZBook 15 G3 or the Precision 5520. Particularly interesting here is the Quadro M620 GPU, which we haven't been able to review thus far. Since the 3520 is a fairly minor update, we are omitting the sections dealing with the input devices, maintenance and security features and will focus on the display and the inner merits instead. Our review workstation with the fastest i7 processor, Full HD display, 32 GB of RAM and 512 GB SSD is the top-of-the-line model and sells for 2500 Euro (~$2800).Īt a first glance, the Precision 3520 looks like the Precision 3510, but there are differences as far as the chassis and the feature set are concerned. Well-equipped mobile workstations cost easily above 2000 (~$2250) and sometimes up to 3000 Euro (~$3360). By these standards, the Precision 3520 is almost a bargain: the entry-level configuration as sold by Dell can be purchased for 1400 Euro (~$1570). Of course, we might have to define what "inexpensive" means here in the first place. Īn inexpensive mobile workstation - isn't that a contradiction in terms? Not according to Dell, who promises that the review notebook - the Precision 3520 - is exactly that. For the original German review, see here.
