A fair bit has changed in the mobile processor space since we last took a look at the market earlier in the year. New handsets have been released, new benchmarks leaked, and a few brand new SoCs have been unveiled too.

So here’s a round-up of all the mobile processor news for the second quarter of the year.

The next generation

Earlier in the year, we were eagerly awaiting the arrival of processors powered by ARM’s new Cortex A15 CPU cores, which were promising substantial performance improvements over the old Cortex A9 generation. Most of the big chip manufactures were lining up their new SoCs, the Exynos 5 Octa and Snapdragon 600 were two of the biggest releases which we’ll take a look at in a bit more detail in a minute, and all the tech junkies were eager to know exactly what these chips could do.

Well, now we know, one of the most obvious changes over the past quarter has been the leap up in mobile processing power. Top of the line handsets launched around the start of the year, like the Xperia Z, have already be surpassed with faster pieces of hardware — just take a look at our benchmark results:

The Cortex A15 may have been the big step forward for mobile processes so far this year, but its implementation has come in many different forms.

Qualcomm Snapdragon

Qualcomm continues to do what Qualcomm does best – produce a range of high quality chips with everything that handset manufactures need already built in. This time last quarter, we were taking our first look at the upcoming Snapdragon 600 processors which would be replacing the older S4 Pro, another incredibly popular Qualcomm processor.

Qualcomm doesn’t use the exact specification for the Cortex A15, it licenses the architecture from ARM which it then implements into its own Krait CPU cores, the newest version of which, the Krait 300, has shown up in the new Snapdragon 600 SoC.

Since then, a range of handsets powered by Qualcomm’s newest chips have appeared on the market, the flagship Samsung Galaxy S4 and HTC One being the two most notable models which are both some of the best performing smartphones on the market. Performance wise, the Snapdragon 600 has proven to be a decent enough jump up from the previous generation, performing well in most benchmark tests.

We’ve also started to hear about a few devices featuring the lower end Snapdragon 400 and 200 chips, with a range of entry level processors using various ARM architectures heading to the market in the near future. So far this year high end smartphones have received the biggest performance improvements, but these new chips should give the midrange a much needed boost later in the year.

So whilst Snapdragon 600 is certainly the most popular high-end chip on the market right now, we’ve already started to see our first snippets at Qualcomm’s next big thing, the Snapdragon 800.

Snapdragon 800

There’s been lots of official and unofficial data floating around over the past few months regarding this new chip, and from, what we can tell, it looks to be one powerful piece of tech. Qualcomm demoed some of the new chip’s improved 3D performance earlier in the year, and more recently we’ve seen a few benchmarks popping up for new devices, which place the Snapdragon 800 at the top of the benchmark scores come it’s release.

First, there was the Pantech IM-A880 smartphone, which scored an impressive 30133 in the popular Antutu benchmark, followed by the rumoured beefed up version of the Galaxy S4, and most recently the new Xperia Z Ultra which pulled in the most impressive score yet, a whopping 32173. We’ve also seen some more official looking benchmarks from AnandTech and Engadget which confirm the Antutu scores of above and around 30,000, and also gives us a good look at how the chip performs in a range of other tests. The conclusion — it’s a bit of a beast.

These notable benchmarks scores are no doubt down to the new higher clocked Krait 400 CPU cores and the new Adreno 330 GPU, which is supposed to offer around a 50% performance improvement over the already quick Adreno 320. The test results we’ve seen have shown that the Snapdragon 800s CPU is fine compared with the current crop of processors, but the chip really shines through when it comes to GPU performance, which has proven to be even quicker than the Tegra 4 and iPad 4 chips.

We’ve already seen that Qualcomm is taking graphics extra seriously with its latest chip, as the Snapdragon 800 became the first processor to receive OpenGL ES 3 certification and is compliant with all the big graphics APIs.

Quite a few upcoming top of the line handsets are rumored to be utilizing Qualcomm’s latest processor, including the Galaxy S4 LTE-A, Oppo Find 7, and an Xperia Z refresh as well, so the Snapdragon 800 is perhaps the biggest chip to look out for in the coming months.

Exynos 5 Octa

Moving away from Qualcomm, there was certainly a lot of hype surrounding Samsung’s octo-core monster of a processor. Upon release, the chip mostly lived up to expectations — the Exynos version of the Galaxy S4 topped our performance charts and is currently the fastest handset on the market. The SoC is the first to utilize the new big.LITTLE architecture, with four new Cortex A15 cores to provide top of the line peak performance, and four older low power Cortex A7s to keep idle and low performance power consumption to a minimum.

The chip is certainly one of the best when it comes to peak performance, but it has had its share of troubled when it comes to balancing power consumption and performance.

The Exynos 5 Octa version of the Galaxy S4 is the fastest smartphone around right now, by a slim margin, but availability varies by region.

If you’re in the market for the fastest smartphone currently around, then the Galaxy S4 is the one to pick right now, providing that it’s available in your region. It has the fastest CPU currently on the market, and its PowerVR SGX544 tri-core GPU matches that of the latest iPad. But with the Snapdragon 800 just around the corner, there could soon be a new processor sitting on the performance throne.

Looking forward, it’s difficult to see the Exynos retaining its top spot for much longer. Other companies are starting to look beyond the power-hungry Cortex A15 architecture, but Samsung hasn’t yet unveiled any new plans.

Intel Clover Trail+ and Baytrail

Speaking of which, perhaps the biggest mover this year has been Intel, and although the company still isn’t competing with ARM in terms of the number of design wins, Intel has finally show off some products which will pose a threat to ARM’s market dominance.

Although we’ve been hearing about Clover Trail+ since last year, the chip is now moving into full swing, with a few handsets arriving which are running the chip, and some of the benchmarks we’ve seen are really quite impressive. Clover Trail+ has managed to find the right balance between performance and power consumption, unlike previous Atom chips which been far too slow to keep up with the top of the line ARM-based processors.

The results show a benchmark score followed by the average and peak current draw during the test. Intel’s chip scores highest on the most tests and draws the least current, and it’s only beaten by the Exynos 5 Octa when it comes to GPU performance.

Then there’s Baytrail. Back at Mobile World Congress earlier in the year, Intel laid out its plans for its Clover Trail+, but we’ve already heard information about the processor’s successor. Intel claims that its new Silvermont cores will further improve on both energy efficiency and peak performance. It sounds great on paper, but we always have to take these unveilings with a pinch of salt. What we are most likely looking at with Baytrail is a decent performance improvement, which should keep the processor ahead of the current Cortex A15 powered handsets in the benchmarks, but energy improvements are likely to come in the form of idle power consumption and low power states, rather than saving energy at the peak performance levels.

Intel Silvermont vs Saltwell performance

But Intel isn’t just interested in breaking into the smartphone and tablet markets with its new line-up of processors. The company is still very much focused on producing chips for laptops. One particularly interesting prospect is the confirmed new generation of Android based netbooks and laptops powered by more robust Intel processors, which could give Microsoft a real run for their money.

Intel has clarified that it will also be assigning the additional Pentium and Celeron titles to its upcoming Silvermont architecture as well as using it in the new BayTrail mobile chips. What this potentially means is a further blurring of the line between tablets and laptops, where the same processor technology will be powering a range of Intel based products. I’m expecting the performance rankings to go from Baytrail for phones and tablets, to Celeron for notebooks, and Pentium chips for small laptops, but this naming strategy hasn’t been confirmed yet. It’s also interesting to see where this will stack up with Intel’s newly released Haswell architecture, which is also aimed at providing power efficient solutions to laptops.

Taking all that into consideration, Baytrail has the potential to be a big game changer for Intel, as it could stand out well ahead of Samsung’s top of the line Exynos chips and will certainly rival the upcoming Qualcomm Snapdragon 800 processor. But we’ll be waiting until the end of the year before we can finally see what the chip can do. In the meantime, we’ll look forward to seeing if Clover Trail+ can finally win over some market share.
