Lenovo Thinkpad Twist Convertible Ultrabook Review
Synthetic Benchmark Testing
SiSoft Sandra 2012
The Thinkpad Twist performed within expectations in both the CPU and memory bandwidth tests. The CPU results scaled well, given the fact that the Twist uses a dual-core i5-3317U mobile CPU. The memory numbers also track correctly, but are muted due to the Twist model tested having one a single stick of memory running at 1333MHz instead of the desired two stick, dual-channel based 1600MHz memory.
LinX is a graphical interface for CPU-based testing using the Intel Linpack benchmarks. It serves as a good indicator of proper system CPU functioning and is considered one of the most intensive CPU benchmarks currently available. LinX was run with Memory set to All and for a total of 3 runs. This test was repeated three times with the highest repeatable GFlops (Giga-Floating Point Operations Per Second) score recorded.
The Thinkpad Twist performed decently when the CPU included in the system is taken into account.
7-Zip is an open-source file compression and decompression software. File compression and decompression are very system and memory intensive, acting as a good indicator for system performance. The 7-Zip benchmark test was run with a 32MB dictionary size, 4 CPU threads active, and for 10 passes per test. The included benchmark test was repeated three times with the highest repeatable MIPS (Millions of Instructions Per Second) scores recorded.
The Twist performs exactly as expected in this benchmark, with its dual-core CPU inhibiting increased performance here.
