SiSoft Sandra & Cinebench

We continued our testing with SiSoftware's SANDRA, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests (CPU Arithmetic, Multimedia, Memory Bandwidth, Physical Disks).

Preliminary Testing with SiSoft SANDRA
Synthetic Benchmarks

The next time you’re thinking of slashing the cost of a system configuration by skimping on the processor, remember these scores: The IdeaCentre 720’s dual-core Intel chip hit Processor Arithmetic and Multimedia scores of 45.71 and 99.78, respectively, while the Dell XPS’s Intel Core i7-3770S pulled down 110 and 244.25. In fact, Lenovo finished dead last in the multimedia test and essentially tied the ASUS system for a distant third in arithmetic.

The Memory Bandwidth scores here are fairly similar across the board, but the Physical Disks test shows the vast differences in the storage systems on these PCs. Most notably, the Lenovo’s slow 5400 RPM hard drive delivered the lowest score of the bunch.

Cinebench R11.5 64bit
Content Creation Performance
Maxon's Cinebench R11.5 benchmark is based on Maxon's Cinema 4D software used for 3D content creation chores 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.

There’s really no competing with the Core i7-3770S in the Dell system in this group, but the HP’s score versus the Lenovo and ASUS systems highlights the difference between quad-core and dual-core processors.

It’s worth noting, however, that the Lenovo posted a solid OpenGL score of 22.5, which was far and away faster than the HP’s 15.37 and the ASUS’s 6.05 thanks to the GeForce GT 630M on board. Of course, the Lenovo system's score paled in comparison to the Dell XPS which sports a beefier GPU.
