Razer Blade Stealth: SANDRA & Sunspider
First up in our benchmark suite is SiSoftware's System ANalyser, Diagnostic and Reporting Assistant (SANDRA). SANDRA gives us a good look at the raw performance throughput of our systems. This makes for a great sanity check to ensure the computer is performing as advertised before breaking out the other benchmarks. SANDRA features a wide variety of tests but the ones we are focusing on are the Processor Arithmetic, Processor Multimedia, Memory Bandwith, and Storage Bandwidth tests. SANDRA is updated regularly so be sure you are on the latest version when testing.
First up we see the processor performing admirably at 73.75 GIPS (billion instructions per second) and 40.87 GFLOPS (billion floating point operations per second). This is a slight lead over the likes of the almost identically specced and pricier Lenovo ThinkPad X1 Carbon we tested at 69.51 GIPS and 40.78 GFLOPS. We see similar leads in the Processor Multimedia with a 2.3% improvement in integer and 9.0% improvement in float scores over the ThinkPad X1 Carbon. Keep in mind that the X1 Carbon rocks the same Core i7-6500U inside a larger frame which theoretically should give it the advantage in heat dissipation, but Razer definitely didn't get that memo. Moving along we actually see memory performance falter by about as much to the X1 Yoga with a 5.5% decrease in integer bandwidth and 4.3% decrease in float memory bandwidth. Finally with storage we see the Samsung MZVLV256 NVMe drive inside stretch its legs with a respectable, though not record-shattering, 1405.5 MB/s transfer rate.
The Sunspider website offers the following about their test:
Sunspider begins to show how quick the Core i7-6500U powered Stealth is. 81.2 milliseconds is a very respectable result for any device running this benchmark. It is only barely edged out by the ThinkPad X1 here which as we saw above with SANDRA is able to load memory just a touch faster than the Blade Stealth is able to crunch numbers, and of course by the XPS 15 which is in a different league with its quad-core i7-6700HQ.
