Earlier today Nintendo took the wraps off of their next generation console, Switch. Formerly known by the codename NX, the Switch is the successor to both Nintendo’s portable DS and set top Wii console lines, utilizing a portable, tablet-like unit that can be docked to behave like a set top console. Today’s announcement, in the form of a 3 minute trailer, is meant to tease the console ahead of its full launch in March of 2017.

While I’ll skip the commentary on the console’s unusual design – dedicated gaming sites can offer better context – I wanted to dive into the hardware in the Switch. Given that this was a teaser, I was not expecting a reveal of any of the hardware specifications of the console, and indeed neither Nintendo’s teaser video nor their related press release made any mention of the underlying hardware. However shortly after the reveal went live, NVIDIA sent out an email to the press and posted a blog of their own. As it turns out, while today is still just a teaser, in some ways we’re already getting more information about the console than in any previous generation of Nintendo’s hardware.

In their blog post, NVIDIA confirmed that they would be providing the underlying SoC for the console. As this is still ultimately a teaser, NVIDIA’s own details are light, but their announcement confirms that it’s a custom version of their Tegra SoC. Curiously, no mention of the CPU core in that SoC is mentioned. However as it’s a Tegra, something ARM-based is the logical (if not only) choice. And on the GPU side, as you’d expect, they’re using a GPU based on one of NVIDIA’s existing GPU architectures, though the company isn’t specifying if it’s Pascal or Maxwell (I’d assume Pascal, but consoles are known for their long development cycles).

Otherwise, as far as specifications go that’s all we get for now. Though as NVIDIA is supplying a whole SoC there are obviously many more parts to the package that we’ll hopefully learn about in the near future. More CPU and GPU details are obviously the most interesting aspect – does the Switch SoC use Denver CPU cores? – but there’s also the matter of memory bandwidth, WiFi support, and the many other functional blocks that make up an SoC.

For NVIDIA, this is the first console hardware win for the company since the PlayStation 3, which launched in 2006. In the set top console market, AMD has since provided the GPU (and often, the CPU) for the most recent generation of consoles. Otherwise NVIDIA has never had a 3rd party portable console win, primarily because both Nintendo and Sony developed their respective SoCs internally for the 3DS and Vita.

In fact, given that Nintendo previously did much of their portable console development work internally, this is a notable shift for how the company operates. The 3DS was essentially a custom SoC combining multiple ARM11 (ARMv6) CPU cores with an OpenGL ES 1.1 generation GPU from the little-known Digital Media Professionals (DMP). So this is the first time Nintendo has contracted out their SoC needs to a third party in such a visible fashion. I’m actually a bit surprised that NVIDIA is even allowed to talk about their involvement at this point in time, given Nintendo’s historical focus on secrecy.

Though all of this also helps to underline just how big a jump in technology the Switch is from the 3DS. On the CPU side alone it’s reasonable to assume we’re looking at CPU design in the neighborhood of 4.x DMIPS/MHz, versus ARM11’s approximate 1.3 DIMPS/MHz rate, so IPC will have increased significantly, never mind an increase in frequency. Meanwhile on the GPU side, Nintendo is going from a GPU that didn’t even have a programmable GPU pipeline (i.e. shaders) to a fully modern GPU, essentially catching up on a decade of mobile GPU development in a single bound. Given that the console has to work as both the company’s portable and set top consoles, Nintendo has opted to use far more modern tech than their traditionally conservative designs.

Finally, without reading too much into a 5 paragraph announcement, there is one other interesting nugget of information in NVIDIA’s blog post that further shows just how deep the NVIDIA/Nintendo relationship is going here. Along with providing the SoC, NVIDIA also has a major stake in the development of the console’s API and middleware. While NVIDIA presumably isn’t developing the entire software stack, they make special note of the fact that they are providing a new “lightweight” API, NVN, for the console. NVIDIA is also providing middleware in the form of “a revamped physics engine, new libraries, advanced game tools and libraries” and “custom software for audio effects and rendering” which sounds a great deal like NVIDIA having brought over major parts of their GameWorks SDK, including the PhysX physics simulation libraries and VRWorks Audio library.

In any case, it will be interesting to see how this plays out over the next few months. The mobile world has changed significantly since the 3DS was launched in 2011, something that the Switch’s design makes obvious. Nintendo has gone in a very different direction than either their console rivals or the smartphone market that is always threatening to encroach on mobile consoles, and that’s reflected in both the unusual dual-mode console and the hardware inside of it.

    Hi alternate account AMD Red Team Plus member.

    AMD Radeon 7850 = 1.76128 AMD Teraflops with 153.6 gBps memory bandwidth

    Nvidia GTX 1080 = 8.228 Nvidia Teraflops at base clock, 8873 Nvidia Teraflops at boost clock with 320 gBps memory bandwidth

    In actual games, GTX 1080 has ~6.2x the performance of the Radeon 7850 with merely ~2.08x the memory bandwidth.

    That's ~3x the memory bandwidth efficiency.
  • Communism - Friday, October 21, 2016 - link

    LPDDR4 3200 32 bit x 2 is 50 gBps, x4 is 100 gBps.

    LPDDR4 3200 32 bit is the standard rate for LPDDR4.

    Nvidia Pascal has 3x memory bandwidth efficiency of PS4, meaning 50 gBps = 150 gBps of PS4 GPU.
    Nvidia Denver and A57 also has much higher memory bandwidth efficiency than AMD Jaguar, which loses in memory bandwidth efficiency to even Intel Atom at the time it was released, let alone now. I'd say over 2x memory bandwidth efficiency for Nvidia Denver vs AMD Jaguar.

    This means that Nvidia would reach parity with PS4 in terms of memory bandwidth with about 50-55 gBps nominal.

    If Nvidia has a 2x Denver, 4x A57 or a 4x Denver CPU configuration, the Nvidia SoC will be over 3x+ as performant in single threaded as well as 2x+ as performant in multi-threaded as the 4x Jaguar + 2x Jaguar taped together by a horrifically slow interconnect (As accessible for games) configuration of the PS4, PS4 pro, Xbone, and probably Scorpio.

    Whoops messed up on the LPDDR4 memory bandwidth calculations, you were right about the 2x LPDDR4 = 25.6 gBps, 4x = 51.2 gBps.

    They're all worth a damn in terms of games, just the last two of been underpowered at launch...the 3DS especially. Still, lots of good games.

    A Nintendo portable with MUCH higher end hardware, only having to buy a single Nintendo console instead of two-both sound nice to me! Not my ideal scenario from what I'd want from Nintendo, but makes more sense than Wii and Wii U did.

    Depending on the price, this could be a good replacement for media consumption tablets as well as being a gaming system.

    The problem is that the bottom fell out of the media consumption tablet market awhile ago.

    Sounds interesting. I see a grill for a heatsink on top...Dare I wonder, maybe even actively cooled? Maybe the dock could blow a stream of air in, if it's not in the tablet. To me it indicates a push past where a Tegra would be in a standard tablet form factor with its TDP limits.
  • psychobriggsy - Friday, October 21, 2016 - link

    Yeah, I saw that and speculated active-cooling in the dock that pushes a stream of air up through the tablet. This could probably effectively cool 20W, maybe 30W easily, depending on the heatsink inside the device.

    I'm buying one, I love the Wii U. You get full console gaming technology while consuming other media such as Netflix or TV.

    All Nintendo needs to do is add 4G LTE. Of course, who says they haven't already?
