On Jan. 27, Dell announced several updates for its Precision M3800, dubbed to be the "world's thinnest and lightest true 15-inch mobile workstation."

Primarily, the revamped notebook brings 4K Ultra HD touch display and Thunderbolt 2 technology. Dell also mentioned the release of the laptop's Ubuntu-based developer edition.

With 4K Ultra HD, the new laptop offers a resolution of 3840 x 2160 pixels. This appears to be the highest resolution existent in a 15-inch laptop today. Interestingly, Dell has been vocal about its intent to compete against Apple's MacBook Pro.

The company wrote, "With more than 8 million pixels, the 4K Ultra HD screen option is the highest resolution panel available on a 15-inch mobile workstation today, boasting 3.4 million more pixels than the Retina display on the Apple MacBook Pro 15-inch and allowing customers to experience 59 percent higher resolution."

For comparison, Dell certainly referred to the MacBook Pro in today's market. But with rampant speculation aimed at the 2015 version of the Apple notebook, which product claims the greater success?

As we have previously reported, the 2015 MacBook Pro is expected to arrive in June's Worldwide Developers Conference. Reports have claimed that Apple is determined to make the new notebook "the fastest one yet."

Aside from Retina display, the new MacBook Pro may bring Intel's new Broadwell chip, 16 GB of RAM and extended battery life, Macworld wrote. Gotta Be Mobile also predicted that the laptop comes with a thinner body, packing Touch ID fingerprint sensor and a new USB port.

However, with the new M3800, Dell assured that customers will be able to view content in greater detail. The screen is made with Corning Gorilla Glass NBT, sporting a 15.6-inch UltraSharp touch display.

As told by ZDNet, the MacBook Pro has retained its 2880 x 1800 display since 2012. At this point, the upgraded M3800 seems to be an advantage -- visually speaking. The outlet also observed the latter's unchanging processor, which remained to be the quad-core Haswell Core i7-4712HQ chip.

Along with M3800's stunning upgrade on graphics, Dell has packed additional storage options and increased the total available internal storage. Now, the notebook offers up to 2 TB of hard drive storage, and this is said to be twice the SSD possessed by the MacBook Pro.

Citing the combination of M3800's newest specs, Digital Trends was convinced, "That's really the best a graphic professional could ever ask for."

Meanwhile, Thunderbolt 2 is an Intel communications port capable of transferring data at speeds up to 20Gbps. Digital Trends wrote that it's also utilized for easy 4K video viewing and editing. The new Dell notebook starts from $1,649, CNET reported.
