MediaTek Follows ARM Cortex-A17 Unveil with MT6595

Our Josh Walrath wrote up an editorial about the Cortex-A17 architecture less than two days ago. In it, he reports on ARM's announcement that "the IP" will ship in 2015. On the same calendar date, MediaTek announced their MT6595 SoC, integrating A17 and A7 cores, will be commercially available in 1H 2014 with devices in 2H 2014.

Of course, it is difficult to tell how ahead of schedule this is, depending on what ARM meant by shipping in 2015 and what MediaTek meant by devices based on the MT6595 platform in 2H 2014.

There are two key features about the A17: a 40% power reduction from A15 and its ability to integrate with A7 cores in a big.LITTLE structure. MediaTek goes a little further with "CorePilot", which schedules tasks across all eight cores (despite it being a grouping of two different architectures). This makes some amount of sense because it allows for four strong threads which can be augmented with four weaker threads. Especially for applications like web browsers, it is not uncommon to have a dominant main thread.

The SoC will also support LTE and HSPA+ mobile and 802.11ac wireless connections. It will not integrate the Mali-T720 GPU (DX11/OpenGL ES 3.0), but instead use the Power VR Series6 GPU (DX10/OpenGL ES 3.0 unless it is an unannounced design). MediaTek does not explain why they chose the one licensed GPU over the other.

MediaTek claims the MT6595 platform will be available in the first half of 2014 with devices coming in the second half.

Cortex-A12 Optimized!

ARM is an interesting little company.  Years ago people would have no idea who you are talking about, but now there is a much greater appreciation for the company.  Their PR group is really starting to get the hang of getting their name out.  One thing that ARM does that is significantly different from what other companies do is announce products far in advance of when they will actually be seeing the light of day.  Today they are announcing the Cortex-A17 IP that will ship in 2015.

ARM really does not have much of a choice in how they announce their technology, primarily because they rely on 3rd parties to actually ship products.  ARM licenses their IP to guys like Samsung, Qualcomm, Ti, NVIDIA, etc. and then wait for them to actually build and ship product.  I guess part of pre-announcing these bits of IP provides a greater push for their partners to actually license that specific IP due to end users and handset makers showing interest?  Whatever the case, it is interesting to see where ARM is heading with their technology.
 
The Cortex-A17 can be viewed as a more supercharged version of the Cortex-A12, but with features missing from that particular product.  The big advancement over the A12 is that the A17 can be utilized in a big.LITTLE configuration with Cortex-A7 IP.  The A17 is more power optimized as well so it can go into a sleep state faster than the A12, and it also features more memory controller tweaks to improve performance while again lowering power consumption.

In terms of overall performance it gets a pretty big boost as compared to the very latest Cortex-A9r4 designs (such as the Tegra 4i).  Numbers bandied about by ARM show that the A17 is around 60% faster than the A9, and around 40% faster than the A12.  These numbers may or may not jive with real-world experience due to differences in handset and tablet designs, but theoretically speaking they look to be in the ballpark.  The A17 should be close in overall performance to A15 based SOCs.  A15s are shipping now, but they are not as power efficient as what ARM is promising with the A17.
