Google Nexus 9: Preliminary Findingsby Joshua Ho on November 3, 2014 1:00 PM EST
For a few years now, Google has had a generally consistent tablet strategy. Instead of chasing after the ~10 inch tablet segment and focusing upon the high end, we’ve seen tablets closer to the ~7 inch display size at extremely low cost. While this has been an immensely successful strategy in driving hardware adoption, the formfactor made it possible for the tablet to be closer to a large phone than a small tablet. The flexibility of Android’s scaling system meant that an app designed for a phone worked acceptably well for a small tablet, even if the space efficiency was a bit poor. There’s no question that the Nexus 7 (2013) was and still is a great tablet, but even now it’s obvious that there’s a dearth of applications designed specifically for the larger display. The other issue is that of cost. With the Nexus 7 line, Google managed to integrate an incredible amount of hardware into a tablet priced well below the ~500 USD price point that the original iPad established. This is great for the consumer and no doubt great for Google, but the Nexus 7 line was good enough that there wasn’t much in the way of competition.
This brings us to the Nexus 9, Google’s attempt at changing the Android tablet space. From the start, this device seems to be intent on pushing the Android tablet to a more premium segment. Rather than a purely cost-optimized polymer design, we see the addition of an aluminum ring that runs around the side of the device, which definitely helps with in-hand feel. The tablet itself seems to have high-end aspirations as the launch platform for NVIDIA’s Tegra K1-64, which has two Denver CPU cores rather than the traditional 4+1 Cortex A15 setup, along with dual front-facing speakers and a large 9” display with 4:3 aspect ratio. I’ve included the basic specs in a spec sheet below, to avoid spending too much time going over the basics.
|SoC||2.3GHz 64-bit dual core Tegra K1 Denver SoC|
|RAM/NAND||2GB LPDDR3 + 16/32GB NAND|
|Display||8.9" 2048x1536 IPS LCD|
|Network||WiFi only or 2G / 3G / 4G LTE SKU|
|Dimensions||153.68 x 228.25 x 7.95mm, 425g WiFi, 436g LTE|
|Camera||8MP Rear Facing (IMX219) with F/2.4 aperture, 1.6MP FFC (OV9760)|
|Battery||6700 mAh (25.46 Whr)|
|OS||Android 5.0 Lollipop|
|Connectivity||802.11a/b/g/n/ac + BT 4.1, USB2.0, GPS/GNSS, NFC|
Unfortunately, in the case of the Nexus 9 while we can make some early observations the version of firmware that we received dates was built on August 29th, and in the time since it’s quite likely that there have been significant changes in all directions. We still don't have a newer build, so all the tests will be done on older firmware. The full review will have final numbers as it will be done using shipping firmware.
At any rate, the hardware of the Nexus 9 definitely fits the bill of a premium tablet. While for the most part every Nexus device in the past year has shared the same industrial and material design elements, HTC seems to have added a few extra touches to differentiate this product from other Nexus devices. The most obvious and prominent of these touches is the metal ring, which has a brushed texture similar to what we saw on the M8.
There are also dual front-facing speakers that flank the display, which are definitely great for video and music content when compared to a single speaker on the bottom or back of the device. However, for the most part the design is very much a Nexus device with its minimalistic design and soft-touch plastic back cover.

baycorn - Thursday, November 27, 2014 - linkwhen is the review coming??? I was going to get a Nexus 9 but now aftet bad reviews am seriously thinking about an ipad mini 2 - waiting for the always great anandtech review before making final decision!
jji7skyline - Sunday, November 30, 2014 - linkI gave up waiting for the review to decide between the Nexus 9 and the iPad Air 2. I just bought the Nexus 9 a few days ago and I am waiting for it to ship.
Maleficum - Tuesday, December 30, 2014 - linkI think the full review is delayed so much because Anandtech is currently consulting lawyers fearing nVidia's wrath. The K1 Denver is the biggest benchmark cheater, Anandtech found it out, and....... you know the story between 3DMark and nVidia.
To be clear: the K1 Denver is an *emulator*, NOT a custom designed ARM. It's so easy to write an emulator that cheats primitive, predictable, synthetic benchmarks.
For example, write a function that does hundreds and thousands times memcpy on same addresses. With the -O3 option, the compiler optimizes the function so that it does memcpy only once.
Benchmarks are written in a way that the resulting machine codes actually do all the iterations, but with an emulator that translates these machine codes to a different one, it can easily mimic the compiler's behavior mentioned above. Of course, it would be "optimization" by nVidia's definition.
This kind of "optimizations" were done before by Transmeta, and K1 Denver is a reincarnation of Transmeta's Crusoe/Efficeon. And we all know that nVidia .......... well, the rest is up to you guys.
PS: Sunspider is one of very few "uncheatable" benchmarks, and you know how Denver fares in that.
dragonsqrrl - Thursday, January 15, 2015 - linkSoo... I know I said I'd wait for a quality analysis, but isn't this a bit much? Are we going to get a Nexus 9 review Josh?
snoukkis - Friday, January 23, 2015 - linkYup, still waiting for the review with the final shipping product...
Vinny DePaul - Saturday, August 22, 2015 - linkI hope someone will see this and help me. I ran those benchmarks on my Nexus 9 and mine is almost 200% slower, i.e., double sunspider score. Did I get a fake Nexus 9?
