System Performance

The Acer Aspire R 13 comes in a couple of different spec levels, with the base model coming with the Core i5-5200U and 8 GB of memory, and the spec bump is to the Core i7-5500U, which is the model that I have today. This is a 2.4 GHz base frequency with a 3.0 GHz Turbo, 4 MB of L3 cache, and Intel’s HD 5500 GPU onboard. The two cores and four threads are all contained within the standard 15 watt thermal envelope of the U series CPUs from Intel.

We’ve been lucky enough to see quite a few Broadwell parts this year, including Core M and several of the U series, and the i7-5500U is near the top end for Broadwell ULV. There are a couple of models above it with a beefier GPU, but those seem to be few and far between in notebooks which is a real shame. It would be nice to see a couple of PC manufacturers step up and include HD 6000 version but I have not seen it happen yet.

To test system performance we put the Acer through our standard notebook workload. To compare the results, I have selected a sampling of comparable devices, but if you would like to check the Acer against any other devices we have tested, please use our notebook bench.

PCMark 7 (2013)

PCMark 8 tries to replicate real workloads with its various tests, including home, creative, work, and storage. All include heavy and light tasks mixed together. The Acer’s Core i7 seems to slot in fairly well between the i5 and top end i7-5600U in the X1 Carbon.


Cinebench R15 - Single-Threaded Benchmark

Cinebench R15 - Multi-Threaded Benchmark

Cinebench is a heavy workload which runs the CPU at 100% for the duration of the test. Once again the higher frequencies of the Core i7 help keep it ahead of the i5 models.

x264 HD 5.x

This is a test of converting a video, and much like Cinebench it is a sustained workload. Higher frequencies additional cores help a lot on this test. The Core i7 processors have slightly higher base and turbo frequencies and will generally do well on this test. On pass two, the Acer drops down quite a bit. This is a very long sustained workload and the Acer may be running into thermal issues here - a point that will be looked at in the GPU testing.

A lot of what we do is on the web, so it is always good to compare web performance. The Core i7 does very well on these tests, coming out with a healthy margin over the i5 models tested.

At this point, the pecking order for the ULV Broadwell processors is fairly well established. The i7-5500U may be the lowest of the mobile Core i7 processors out right now, but it is still a nice bump in performance over the i5 models. The one concern is a drop in performance over sustained workloads which is generally an indicator of thermal issues.

    "Tent mode is also very useful, either when in cramped conditions such as in an airplane, or when you have a tablet to set the device on and want to use it in touch mode"

    Why would you want to set one tablet onto another tablet?

    Pretty sure he meant table.

    Good to be third!

    Btw you guys from anandtech should leave a link to download those ICC profiles you calibrated. Really helps!

    "What makes the Aspire R 13 somewhat unique "

    As you suggested it's not really unique. Dell was, as far as I recall, the first to feature a machine like this with their Dell Inspiron Duo. Not a bad machine.

    Pretty sure the first machine like this was the Vadem Clio

    This was actually a pretty cool little device for taking notes at school, at the time, since most laptops back then were several pounds heavier and more expensive.

    We have a WINNER! You cannot dispute the link. Well done that man.

    This device could really be helpful with it being so light and not bulky. However, the price does seem a little steep. Also, the unique point is not really true, I think. Dell, did have something similar launched way before this product.

    I would still take the Lenovo Yoga Pro 3 over this device. The pricing is more competitive from Lenovo, and getting a 512GB SSD in the Yoga Pro 3 isn't going to cost you a body part.

    I get where you're coming from, but I won't touch another Lenovo after their malware/poisoned cert fiasco. Too bad no one else has stepped up to make a really great Yoga Pro competitor.
