Dell Inspiron 14z Ultrabook Review

SiSoft SANDRA, ATTO, & Cinebench

We began our testing with SiSoftware's SANDRA 2011, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests that partially comprise the SANDRA 2011 suite (CPU Arithmetic, Multimedia, Memory Bandwidth and Physical Disk Performance). All of the scores reported below were taken with the Dell Ultrabook running at its default settings with full performance mode enabled and the notebook plugged into the AC adapter.

Synthetic General Performance Mertrics

SANDRA CPU Arithmetic and Multimedia Performance

SANDRA Memory and Physical Disk Performance

In putting the Inspiron 14z through its paces, synthetic benchmarks like SANDRA give us an overview of performance, but it doesn't tell the whole story. In particular, SANDRA fails to gauge the performance impact of the 32GB mSATA SSD, which pays dividends the moment you press the power button. At the same time, SANDRA does reveal the limitations of a 5400 RPM hard drive for disk intensive chores

On the CPU and memory side, the Inspiron 14z posts strong numbers in SANDRA, just as we would expect from an Ivy Bridge processor and high frequency DDR3-1600 memory.

Dell Inspiron 14z and Asus Zenbook SSD Performance Comparison with ATTO
We were so impressed with the SSD performance numbers with our first round of ultrabooks that hit the lab, that we had to double check with ATTO to make sure everything was on the level. Here's how it shook out:

Asus Zenbook UX21

To this day, the Zenbook holds the crown for fastest disk performance from an Ultrabook, at least in our labs. Can the Inpiron 14z usurp the king?

Dell Inspiron 14z

Not today. The Inspiron 14z posted respectable read and write transfers in its own right, topping out at over 87MB/s (write) and 325MB/s (read). Subjectively, all around performance is snappy and responsive; objectively, the Zenbook's high-performance SSD still reigns supreme in this benchmark.

Cinebench R11.5 64-bit
3D Rendering Performance

Maxon's Cinebench R11.5 benchmark is based on the company's Cinema 4D software used for 3D content creation and tests both the CPU and GPU in separate benchmark runs. On the CPU side, Cinebench renders a photorealistic 3D scene by tapping into up to 64 processing threads (CPU) to process more than 300,000 total polygons, while the GPU benchmark measures graphics performance by manipulating nearly 1 million polygons and huge amounts of textures.

Looking at the CPU portion of this test, the Inspiron 14z doesn't separate itself from the pack in either direction. But when we examine the GPU/OpenGL component, Dell's latest Ultrabook is able to hit another gear with its AMD Radeon HD 7570M GPU that systems equipped with Intel HD graphics (3000 or 4000) simply don't have. This is the best OpenGL score we've seen from an Ultrabook to date.
