Intel Core i5-520UM benchmarked on Asus UL30JT

By Andrei Girbea - @ andreigirbea , updated on November 11, 2013

Like I’ve told you yesterday, I have the Asus UL30JT laptop on my desk right now (and you can read the review here). And since this is the first notebook with the new ULV Arrandale hardware inside I get my hands on, giving it a more detailed benchmark sounded like a good idea.

The results will be presented in this post, which i believe is one of the first in the world with benchmarks on the Core i5-520UM processor.

First of all, let’s see what’s with this CPU:

  • Part of the Arrandale platform and built on 32 nm
  • clocked at 1.06GHz, but with Turbo Boost technology, increasing frequency to up to 1.86 GHz when needed
  • 3 GB cache L3 (and 32 KB L1, 512KB L2)
  • uses Intel HM55 Express Chipset and integrated Intel GMA X4500 graphics, with variable speed from 166 to 500 MHz
  • 18W TDP for the entire package

More about this processor on Intel’s site.

Besides this CPU, the Asus UL30JT also brings the Nvidia GeForce 310M graphics. In fact, it offers a hybrid solution intelligently managed by Nvidia’s Optimus technology.

With all these, you would expect the UL30JT to be fast. And it really is. You will find some tests and benchmarks below. And since this configuration is meant to be a replacement for the SU7300/SU9400 + GMA 4500HD platform, I’ve tried to compare the performance levels of the three.

SuperPI 1M

  • Core i5-520UM : 21 s
  • SU7300 : 34s
  • Su9400: 33s

SuperPI 2M

  • Core i5-520UM : 49 s
  • SU7300 : 78s
  • Su9400: 78s

wPrime 32

  • Core i5-520UM : 36 s
  • SU7300 : 67s
  • Su9400: 66s

wPrime 1024

  • Core i5-520UM : 1199 s
  • SU7300 : 3417s
  • Su9400: 2131s


  • Core i5-520UM : – (did not manage to make all the tests run properly in order to get a score. But I’ll keep trying.)


  • Core i5-520UM: 6326 3DMarks / 9879 CPUmarks

  • SU7300 : 1190
  • Su9400: 1185

Update: Both 3Dmark scores are for the default CPU frequency (1.06 GHz). I don’t know how i can make it run at Full Turbo Boost and run the tests again. If you do, please help. Also, drivers might have something to do with the performances and we could expect them to be better once new versions pop-out.

Also, here are the results of the CPU benchmarks in SySoftware Sandra (compared with some other CPUs, but i couldn’t compare them to the Su7300 and SU9600 as it didn’t had info for them):

Plus a HDTune test of the 640 GB hard-drive found inside this Asus.

All in one, it’s pretty obvious the new platform is potent. Improvements over the older ULV configuration are between 30 to 50% (and 100%+ in terms of graphics) in different aspects and they are visible during real life usage, not only on paper.

However, at least on the UL30JT, this Arrandale platform is noisier and gets hotter. I’m working on getting a proper tool to measure those temperatures and should have it soon. Same SySoftware Sandra displays 61 degrees Celsius (141 F) for the motherboard and 66 (150 F) for the CPU, in Idle.

If you guys would need some more tests, please point what exactly and I’ll try to run them, as long as i can find the application and is free 😛
