Performance and Benchmarks
It’s important to note that the Intel Core i5-2400S quad-core processor (2.5GHz) is a little slow for a quad-core processor, although it reaches 3.3GHz Turbo Boost, which will be just fine for multi-tasking and running office productivity apps. We also want to note that it doesn’t have hyperthreading like most of the CPUs that came out in Q1 2011 (hyperthreading allows users to run multiple apps at once efficiently). Thus, the i5-2400S was put in the Edge 91z to keep the cost of this AIO with these specs around $950. The large FHD screen with edge to edge glass is what Lenovo decided to focus on instead, and we’re betting it chewed most of the cost up for production. The 4GB-1333 of memory is good and standard and will help boost response time. The Intel HD graphics card is also standard for business machines. It’s not intended to play graphics-heavy material, though, but full HD 1080p video plays graciously–we tested it out with an FHD movie trailer and benchmarks just to be sure. The 500GB Seagate hard drive in our review unit is what we’d consider slower–although is the standard for business machines once again–despite its 7200rpm spin speed. All in all, the Edge 91z’s performance will satisfy most all business users.
