Will nVidia’s Tegra 5 Go LTE?
The tradition continues. Our sources are confirming that Nvidia’s Logan SoC, possibly called Tegra 5, doesn’t come with an integrated LTE modem. Just like Apple, Nvidia makes a big fast chip with impressive Kepler based GPU, but it won’t put a an icera LTE solution inside the same chip.
Icera i500 is Tegra 5 compatible and it has AT&T certification. As the launch draws near, it should become compatible with other US and international LTE carriers like Verizon and T-mobile.
This should not be a big issue for Nvidia’s target market, manufacturers will have to choose two chips instead of one, a clear competitive disadvantage compared to future Qualcomm chips with Adreno 400 graphics and updated CPU cores, expected in early 2014.
During Nvidia’s recent conference call, CEO Jen Hsun Huang said devices based on the new Tegra 4i with integrated LTE should be announced in Q1 and ship no later than Q2. Jensen also mentioned that people are going to be “delighted by the OEM that it comes from” which is probably his way of of announcing some big brand design wins, but he also emphasised that the designs will be global rather than US. For US success you need CDMA Jensen said, but as far as we know Verizon is the only company using it.
Since Apple can pull of two chip designs from day one, we can only assume that two chip approach won’t cost much battery life compared to single chip design that has LTE on board (Snapdragon 600 and 800 ed. ). However, Nvidia is likely going to be making bets on its Kepler based GPU, expected to be the fastest graphics core ever integrated in a mobile SoC that will rock tablets and some phones around the world. The fact that Logan is likely to pack very powerful graphics sans on-die LTE makes it a bit more interesting for tablets than phones, which is exactly what we saw with the Tegra 4.
We expect to see Tegra 5 devices announced at CES 2014 so early January and with some luck we might see them shipping very early in 2014.
Will Qualcomm Be First?
We could not get the right timeframe for the launch of Qualcomm’s successor to the high-end Snapdragon 800, but there is no doubt that Qualcomm, Samsung, Nvidia and other ARM supporters are thinking about 20nm products where some of them will be based on Cortex A57.
Qualcomm has its own Krait core that can be adapted to 20nm and follow up the success of Snapdragon 600 and the soon to come Snapdragon 800. It turns out that it traditionally takes 18 to 24 months for the mobile industry to shift from one process to another and Qualcomm had its first 28nm part in April 2012, with the Snapdragon S4, used in the HTC One S. The first ever 28nm part from Qualcomm was the Snapdragon S4 MSM8260A that is now more than a year old and a relatively obsolete product.
Less than a year after the first 28nm product Qualcomm followed up with the Snapdragon 600 that is shipping in millions of high end devices right now. In a month or two it plans to release Snapdragon 800 based on new Krait 400 core and add a new core and get even better performance.
The next step is the 20nm core that should start shipping before the end of 1H 2014. We would not be surprised to see 20nm Krait demoed at CES 2014 already in January, see more of it at the Mobile World Congress in February and the volume shipment to follow in early Q2 2014. This is the expected schedule and not something we got from Qualcomm.
The only official world we got is that the new generation traditionally comes 18 to 24 months after the first iteration of a current one. This can give you an idea that Tegra 5, codenamed Logan, should show up at a similar time, along with Samsung’s 20nm Exynos.
