Earlier this week Google announced two new flagship Nexus devices: the Nexus 4 smartphone and the Nexus 10 tablet. We received review samples of both earlier this week, and while we're hard at work at full reviews of the devices we couldn't help but share all of the test data we've been able to amass at this point.

For those who aren't familiar with it, the Nexus 4 features Qualcomm's Snapdragon S4 Pro SoC - a quad-core 28nm Krait CPU with Qualcomm's next-generation Adreno 320 GPU. The combination proved quite formidable in the MDP/T we tested, as well as LG's recently announced Optimus G. The SoC drives a 4.7-inch 1280 x 768 IPS display and is paired with 2GB of LPDDR2 memory. The Nexus 4 ships unlocked with 8GB of NAND for $299 without a contract ($349 for the 16GB version). Pair that with DC-HSPA+ support and you get an absolute killer smartphone for use on T-Mobile: no contracts, very low monthly fees, and compelling cellular performance:

Brian will talk more about the combination in his full review, but rest assured that the lack of LTE is workable depending on T-Mobile coverage where you live/travel to.

The Nexus 10 also boasts a brand new SoC: Samsung's Exynos 5 Dual. The Exynos 5 Dual features two ARM Cortex A15 cores running at 1.7GHz as well as ARM's own Mali-T604 GPU. This happens to be the exact same platform used in the new Chromebook, just running Android. The Nexus 10 features a 10.1-inch 2560 x 1600 display, giving it the same resolution as the 13-inch MacBook Pro with Retina Display - but in an even smaller form factor. Google is also aggressive on Nexus 10 pricing: the 16GB WiFi-only tablet sells for $399, with the 32GB version going for $499.

Both Nexus devices run Android 4.2 and are guaranteed to be the first devices to be updated to upcoming Android revisions for the foreseeable future (it's the power of Nexus).

We haven't had a ton of time to test the devices and put this together so you're going to see combined performance charts throughout the rest of this article.

CPU Performance

The big story when it comes to CPU performance is a look at how the Cortex A15s perform under Android. Unfortunately we're still left with mostly browser based benchmarks to measure CPU performance, which actually highlights a major issue in our testing: Android V8 optimization doesn't seem to be anywhere near as good as it is under Chrome OS or Windows. As a result, all of the Nexus 10 performance scores end up slower than the new Chromebook - despite using the same SoC and running Chrome on both platforms. It's also possible that the Exynos 5 Dual in the Chromebook is allowed to burn a bit more power, translating to better performance, but either way the solution here in the Nexus 10 doesn't look as good across the board.

SunSpider Javascript Benchmark 0.9.1 - Stock Browser

SunSpider performance is good, but not significantly better than Qualcomm's Krait based Snapdragon S4. Both the iPhone 5 and RAZR i are able to outperform the Nexus 10. The S4 Pro based Nexus 4 tends to be in line with other S4 based devices - SunSpider doesn't really give much credit to the extra 2 cores.

BrowserMark

BrowserMark puts the Nexus 10 behind many platforms that should be faster, I'm even wondering here if there's some hard partitioning of memory bandwidth between the CPU and GPU to drive the 2560 x 1600 display that's simply choking the CPU here.

The Nexus 4 does ok, but again there seem to be some V8 optimization issues at work here under Android 4.2. At 1.5GHz it should deliver at least the performance of the dual-core Snapdragon S4 solutions.

Google Octane Benchmark v1

Octane is the first test where the Cortex A15s are really able to flex their muscle - the Exynos 5 Dual based Nexus 10 manages to outperform the RAZR i by 34%, and compared to the A6/Swift based iPhone 5 the advantage grows to 64%.

The Nexus 4 performs about in line with other Snapdragon S4 based devices, although once again the extra 2 cores don't seem to be doing much for it here at all.

Mozilla Kraken Benchmark

Kraken also paints the Cortex A15 based Nexus 10 in a good light: there's a 30% advantage over the RAZR i and a 76% advantage over the iPhone 5. These numbers will shrink a bit compared to other tablets, but not by much. The Nexus 4, once again, ends up performing similarly to dual-core Snapdragon S4 based devices.

Overall, the Nexus 10 results show us some real promise for what we can expect from ARM Cortex A15 based SoCs. The potential upside to this new architecture is huge.

    Instead of iPads, other Android tablets, and even Microsoft Surface/Windows RT tablets?? Reply

    Oh, OK -- you've got iPads on the GPU and display benchmarks (I commented after only reading the first page). Reply

    The iPad 4 uses the same components as the iPhone 5 so both wipe the floor with the Nexus 10 Reply

    The iPad 4 has about twice the graphics performance of the iPhone 5. So it's really up there in terms of GPU (I don't think anything else comes close at this point) Reply

    Love my job, since I've been bringing in $5600… I sit at home, music playing while I work in front of my new iMac that I got now that I'm making it online(Click on menu Home)

    Ipad 4 had A6X with 500Mhz 543MP4, iphone 5 had 266mhz clocked 543MP3. Reply

    Too bad ipad and iphone are made by a(ssholes)pple.

    Also, the screen and resolution on Nexus 10 will put iTiny and iUseless to iShame :P

    Keep dreaming hater. The only useless thing here is your envy of Apple products in face of its clear performance superiority.

    All you will be able to say is: "but but this screen says it has more ppi, yes you cannot see it, but it is there, it says so in my spec sheet."
