At the World Mobile Congress, Intel should debut it's Clover Trail+ SoC for Smartphones. It's dual-core with latest graphics and LTE 4G support. Current Medfield is single core found in the Motorola Razr i is found to outperform and has longer lasting battery life than it's arm counterpart found in the Motorola Razr M (snapdragon S4). Imagine a dual core version. It will be interesting to see the benchmark comparison between Clover Trail+ vs. snapdragon 600/800.
Intel mentioned at CES that it will release Bay Trail (22nm process) for tablet market for holiday season, so expect Merrifield (also 22nm) for smartphone market to also be available at that time as well.
Currently Clover Trail. AnandTech recently compared the Acer Iconia W510 (Clover Trail) against arm tablets - ms surface rt (tegra 3), Dell XPS 10 (snapdragon S4), and Nexus 10 (samsung's A15 Exynos 5). AnandTech tests showed Clover Trail beating both tegra 3 and snapdragon s4 in terms of performance. Clover Trail beat tegra 3 in power consumption and was on par with the snapdragon s4. When compared with the samsung's A15, arm's latest and greatest, there was a big surprise. Even though the A15 outperform the Clover Trail (Intel's 5 year old architecture), the A15 was found be consume WAY more power. It's peak TDP was a whopping 8W! This was a big surprise since it proved that arm processors do not really have any power advantage over intel's.
Future: This year we will see Clover Trail+, Ivy Bridge Celeron mobile parts, Ivy Bridge 7W parts, Haswell. Bay Trail for holiday season.
Intel seems to have made such progress reducing power for the Core architecture that Core parts will be the preferred solution for tablets, ultrabooks and everything higher in the foodchain. Clear advantages are 64 bit performance and full compatibility with all software people run today, ie; legacy Windows software, Linux and other operating systems. In reality, Intel is competing with itself as Atom was previously envisioned for some of the product areas Core is now able to serve well.
Today Atom is still the best overall fit for smartphones, wearable computers and devices where battery life is paramount, however even that could change when 14nm arrives. Given the progress Intel has demonstrated already it is not too difficult to imagine 64 bit Core architecture from smartphones to supercomputers. The advantages to product developers and users would be a game changer.
