Performance and Benchmarks
We began our testing with SiSoftware's SANDRA 2014 -- the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests that partially comprise the SANDRA 2014 suite (CPU Arithmetic, Multimedia, Physical Disks and Memory Bandwidth).
SANDRA CPU, Multimedia and Arithmetic
Memory and Physical Disk Tests
Intel’s Core i7-5500U performed well in the Processor Arithmetic test, outpacing a Core i5 though (unsurprisingly) behind an AMD A10 and Intel Core i7-2630QM. In the Multi-Media benchmark, it outpaced a Core i7-4510U as well as an i7-4600U. Memory bandwidth of the 8GB DDR3L-1600 RAM peaked at just over 9.9GB/s, while the Samsung PM851 256GB SSD put up good numbers in the range of 429MB/s range.
Balanced - This test is balanced between different areas of the language and different types of code. It's not all math, all string processing, or all timing simple loops. In addition to having tests in many categories, the individual tests were balanced to take similar amounts of time on currently shipping versions of popular browsers.
Statistically Sound - One of the challenges of benchmarking is knowing how much noise you have in your measurements. This benchmark runs each test multiple times and determines an error range (technically, a 95% confidence interval).
The Inspiron 13 7000 SE ran neck-and-neck with Asus' latest 2-in-1 as well as Microsoft's Surface Pro 3 for the top spot in our SunSpider test. (Of note, this score was notched in Internet Explorer. We ran the same test in Google's Chrome browser and received a score of 277.7ms, nearly 3x as slow as IE. From desktop to mobile, Chrome continues to fair poorly in the SunSpider test, though real-world snappiness when browsing is good.)
