SiSoftware Sandra and Cinebench Performance

Preliminary Testing with SiSoft SANDRA 2011
Synthetic Benchmarks

We started off our testing with SiSoftware's SANDRA 2011, the System ANalyzer, Diagnostic and Reporting Assistant.  We ran four of the built-in subsystem tests (CPU Arithmetic, Memory Bandwidth, Physical Disks).
All of the scores reported below were taken with the processor running at its default clock speed with 4GB of DDR3 RAM running in dual-channel mode.

Processor Arithmetic


Memory Bandwidth

SiSoft Sandra didn't reveal anything surprising; the X230T struggled in the hard drive department, where the 5400RPM spindle rate of the 320GB Seagate drive hindered it significantly. The Core i5 CPU managed to hold its own, however. Unfortunately, Memory Bandwidth scores recorded here were well below average for an Ivy Bridge system.  It appears Lenovo decided to configure the machine with a single 4GB stick of memory in single channel mode.  We're use to seeing Ivy Bridge machines offer up in excess of 18GB/sec of memory bandwidth.  The X230T is only able to put out a little over 10GB/sec in this setup.  Lenovo didn't do the system any justice with this memory configuration and it's going to hurt in multimedia workloads especially where graphics is a concern.

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.


Our Cinebench scores were solid and the X230T was able to best these previous generation Sandy Bridge-based rivals in both CPU and graphics (OpenGL) testing.  Impressive actually.
