SlashGear 101: NVIDIA Tegra 4 inside detail

At CES 2013 you saw the unveiling of the NVIDIA Tegra 4, a mobile processor the organization recommended was the World’s Fastest, it containing 72 GPU cores, five CPU cores (1 of them an A15 “companion”), as well as the ability to function with 4G LTE. The Tegra 4 is using the NVIDIA Icera i500, which being a 28nm HP, Category 3 LTE (4 inside the pipeline) Soft Modem. These 2 pieces of architecture together is NVIDIA’s hero development for mobile equipment throughout 2013.


NVIDIA Tegra 4

The NVIDIA Tegra 4 System-on-Chip with five ARM Cortex A15 cores – 4 of them with 1.9GHz max clock speed, a fifth synthesized to function at lower energy. The technologies functioning about this fifth Companion core is synonymous to the Tegra 3, as well as for the lay individual, it might also be presented because the same due to how synonymous it is. The fifth core is not noticeable to the running program you’re utilizing (whether it is Android, Windows, or anything else), performing because more of the “Shadow Core” or perhaps a “Ninja” because we’ve been apt to call it, merely because it was with Tegra 3.

Above you’re going to find a rundown of what Tegra 4 is, how it compares to Tegra 3, plus what the future holds for mobile processing. The speak you’re seeing above is with NVIDIA Technical Marketing Director Nick Stam whom presented you more of the detailed consider the Tegra 4 plus exactly what it signifies for mobile equipment inside 2013 (plus beyond.)


For those of we which wish To receive very technical with it all, you’ll be interested inside understanding which the die size here inside this brand-new model is 80mm^2, ever thus somewhat bigger than Tegra 3, however a lot denser also. The cores you’re seeing here function about 28nm HPL, which being 28nm low force with high-k and metal gates. What which basically signifies here is the fact that you’re going to receive 1 very optimized experience, created for significant performance plus low force expenditure – because each good processor must.


The Tegra 4 processor is using “Always-On” HDR camera technologies also. You’ll find a rather interesting set of details inside the initial show post, plus we’ll be seeing this development in-person sooner than later. It’s then which we’ll be seeing just what it truly signifies to be capable to quickly take a shot with numerous exposures at once!

NVIDIA Icera i500 Soft Modem with 4G LTE

The NVIDIA Icera i500 Soft Modem is what the organization describes because 40% small than a traditional die – this referring to additional modems they’ve worked with from firms different than themselves, naturally. The Icera i500 usually function with Soft Modem technologies, beginning with UE Category 3 LTE (100 Mbps downlink about 20 MHz FDD-LTE) plus moving forward to UE Category 4 LTE inside the close future. VoLTE is supported with additional voice mode technologies, as well as the modem is paired with a new not before enjoyed transceiver built about 65nm LP CMOS.

The NVIDIA Icera i500 Soft Modem is made about TSMC’s 28nm excellent performance High-K Metal Gate task, as well as the organization can energy gate every of its cores individually. Depending found on the requires of every device’s software, every of the NVIDIA Icera i500′s 8 cores is utilized or not selected, gating based about changing load conditions.

Following Tegra 4

Those of we getting pumped up regarding Tegra 4 plus NVIDIA’s full 2013 experience, you’ll have a fabulous time hitting up the huge Tegra Hub. There you’ll discover not only a everyday NVIDIA Tegra mobile processor information, yet featured hands-on articles, must-read up-to-the-minute updates, plus reports of Tegra-toting equipment of all types.

Right this minute you’ll find many stories found on the initially device to have been revealed using the Tegra 4 processor: NIVIDA’s own Project SHIELD. You’ll find a great amount of awesome Project SHIELD action inside the immediate future plus up with its final name several amount of time in Q2 of the year. Also have a peek inside the timeline under to find the initially significant detail articles to have come down the line here inside the initially week because Tegra 4 was initially revealed – Project SHIELD included!
