PROCESSOR AND PERFORMANCE

Lenovo ThinkCentre boasts a very fast performing Intel Core i5 9th Gen Processor that delivers unprecedented processing power and speed. It lets you edit photos; audit Excel sheets, prepare presentations, and download apps without showing any signs of lag or slow down. So, with this Intel Core i5 PC, you can multitask seamlessly even when you have to work with the most intensive and demanding tasks. Expect high responsiveness from the ThinkCentre owing to its PCIe SSD, 3D NAND technology and optional Intel® Optane™ Memory.

IdeaCentre offers the best performance for daily computing. Owing to its AMD Ryzen 3 processor, this all in one PC makes it easy to get done with simple everyday tasks including working on essays, browsing the web, streaming TV on demand, editing photos, and watching movies, etc. This Ryzen PC is great for studying. Moreover, with this laptop, you also get your very own digital virtual assistant that lets you focus on your work by taking care of your daily tasks. So, with the help of Windows Cortana, you will not have to remember everything on your family’s to-do-list because Cortana will take care of it. Cortana not only takes care of your reminders but it also opens your applications on your voice commands, tracks any incoming parcels, search files for you based on when and whom you worked on a file with, and much more.

Security

The Lenovo ThinkCentre has a very complex security system that makes sure that your data remains safe and hackers cannot crawl their way inside your operating system. This Core i5 PC keeps your enterprise-critical data and passwords safe with the help of its embedded Trusted Platform Management (TPM) 2.0 data encryption that enables the user to work stress-free without worrying about your data getting leaked or stolen. Moreover, with the BIOS-based Smart USB protection, you can stay assured that your data will not end up in wrong hands. The BIOS-based Smart USB protection technology allows you to configure Lenovo ThinkCentre’s USB ports to respond only to specific devices decided by you. This prevents unauthorized personnel from gaining access to your files and copy whatever they want.

Lenovo IdeaCentre, unfortunately, is not very clever when it comes to security and privacy. This intuitive Lenovo all in one PC does not possess the security features that come with the Lenovo ThinkCentre. When you purchase the Lenovo IdeaCentre, you do not get the full version of Microsoft Office or any Internet Security Software. But you do not have to worry about this because it is not an issue. You can easily purchase great MS office deals and amazing security bundles that will save you a lot of money such as the Microsoft Office Home & Business 2019 and the BullGuard Identity Protection, etc.

DISPLAY

Lenovo ThinkCentre M920z comes with a 23.8-inch display screen that delivers Dedicated Graphics. It features an antiglare display panel that scatters light. Thus, it remains flicker-free and reduces eye strain. Moreover, your eyes will stay comfortable even when you have to work those long office hours, thanks to ThinkCentre’s Eye Comfort and Low Blue Light certifications.

On the other hand, IdeaCentre has a 21.5-inch display that delivers On-Board/Integrated Graphics. Watch movies and TV shows with crystal-clear clarity. Its Full HD screen with 1080p resolution is perfect for movie nights. So, if you are not into the same Netflix documentaries as the rest of your siblings, you can use your IdeaCentre to watch your favorite show.

THE VERDICT

Keeping all the important features in view, including processing power, speed, graphics, connectivity options, performance and most importantly security measures, it is safe to say that Lenovo ThinkCentre M920z is a better all in one PC as compared to Lenovo IdeaCentre. Lenovo IdeaCentre is perfect for light computing. You can use it to deal with your daily tasks but if you want to meet deadlines and complete power intensive tasks then you will need Lenovo ThinkCentre.
