General Zenbook UX305 Performance


We ran 3DMark on battery power and got an overall score of 2,871 in Cloud Gate and 1,417 in Sky Diver. On Cloud Gate we scored 15.6 FPS on Graphics Test 1 and 14.9 FPS on Graphics Test 2.


When plugged into the wall outlet we found that the scores improved up to 3,075 in Cloud Gate and 1,497 in Sky Diver. On Cloud Gate we scored 16.7 FPS on Graphics Test 1 and 16.0 FPS on Graphics Test 2, which is an improvement of about 7%. If you are wanting the best gaming performance possible you’ll want to ensure the laptop is plugged in as gaming on the battery is not the same even if you have the system set to ‘High Performance’ in Windows 8.1!


In Cinebench Release 11.5 we scored 14.31 FPS on the OpenGL test and then 1.70pts on the mult-core CPU benchmark.


On Cinebench R15 we scored 13.81 FPS on the OpenGL benchmark at 128cn on the multi-core CPU test.


The benchmark built-in 7-zip showed that the ASUS Zenbook UX305 had a total MIPS rating of 5,318.


A quick look at the memory performance showed 15.27 GB/s of bandwidth. This is about where we expect it to be for a dual-channel DDR3L memory kit running at 1600MHz with rather loose timings of 12-15-15-34 1T memory timings.


AIDA64 v5.20.3449 Beta showed memory read speeds of ~18,000 MB/s and write speeds of ~23,000 MB/s with a memory latency of 80.5ns.

In Sandra Processor Arithmetic the aggregate native performance score was 25.91 GOPS.


We ran the SunSpider 1.0.2 JavaScript Benchmark on Google Chrome 43 and received a score of 300ms.


In the Encryption Algorithm Benchmark that comes inside TrueCrypt we found an AES mean score of 943 MB/s.


Our Geekbench 3.3.2 single-core score was 1,946 and the multi-core score was 3,159.


The last performance test that we wanted to run was Bootracer 4.9 to see how fast the system is able to boot Windows 8.1 64-bit. We found that it took just shy of 30 seconds to get everything up and running on the desktop!
