Yes it was designed around the same time as the Switch 2 chipset back in 2018/19 and shares the same fabrication node but its certainly not relevant to the Switch 2 spec with regard built in support chips which is a much more cut down mobile device designed for a TDP of less than 10W likely around 6W. I don't understand why you have mentioned this it adds nothing to the conversation and isn't relevant at all. Yes ARM A78s are typically much more powerful than PS4 Jaguar cores but not if you run them at 1Ghz they are designed to be fabricated on a 5Nm node ideally with a speed of up to 4Ghz (actively cooled). Frankly they are poor performing at 1Ghz and we know the cache will be reduced to be fabricated on a mainly 10Nm node. Anyway there are benchmarks that clearly indicate their performance and this backed up by Virtuos in that the overall speed is a bit faster than PS4 which is exactly where a passmark of 2000 sits in CPU performance. Surely with all the data out there and the developers themselves stating this its not really debatable. I've got a Razer Edge android games console that I picked up for £100 and that has 3 ARM A78 cores at 2.4Ghz on the optimal 5Nm node plus 4x A55 at 2Ghz and 1 super core X1 at 3Ghz which is competitive with high performance x86 CPUs. All those together works out at about a passmark of 4000 for CPU performance, still less than half that of the Steam Decks 9000 figure. The Switch 2 has very weak CPU performance of less than a quarter of steam deck. It's strengths are all in its GPU not CPU performance. OrinNvidia announced the next-gen SoC codename Orin on March 27, 2018, at GPU Technology Conference 2018.[157] It contains 17 billion transistors and 12 ARM Hercules cores and is capable of 200 INT8 TOPs @ 65W.[158] The Drive AGX Orin board system family was announced on December 18, 2019, at GTC China 2019.Nvidia has sent papers to the press documenting that the known (from Xavier series) clock and voltage scaling on the semiconductors and by pairing multiple such chips a wider range of application can be realized with the thus resulting board concepts.[159] In early 2021, Nvidia announced the Chinese vehicle company NIO will be using an Orin-based chip in their cars.[160]The so far published specifications for Orin are:
Nvidia announced the latest member of the family, "Orin Nano" in September 2022 at the GPU Technology Conference 2022.[167] The Orin product line now features SoC and SoM (System-On-Module) based on the core Orin design and scaled for different uses from 60W all the way down to 5W. While less is known about the exact SoC's that are being manufactured, Nvidia has publicly shared detailed technical specifications about the entire Jetson Orin SoM product line. These module specifications illustrate how Orin scales providing insight into future devices that contain an Orin derived SoC. |
Yes the Tegra in the Switch 2 is a deviation from the Tegra Orin, but it's not that much of a fucking deviation that was a chip built from the ground up which omitted fixed-function processing blocks, it's based on an existing design with a ratified stencil pattern, nVidia still needs to stick with it's establish design rules so they don't need to get the chip re-evaluated by outlets like FCC/IEEE/IEC/CISPR and more which takes time and money.
But this is all common sense and I am sure you were apprised of that, right?
Every ARM SoC for over a decade has literally included a network processing engine so as not to burden the CPU and save on power.
Same goes for Audio.
Same goes for video.
ARM SoC's were always designed around the concept of fixed function blocks to offload specialized tasks to save on power and increase performance.
If you disagree with that... Then I am sorry. But you are just wrong. - Your copied/pasted rubbish neither confirms nor refutes my previous post in any capacity.
As for the CPU performance... Again... If you even bothered to read my actual post, even if the Switch 2 CPU was equivalent to Jaguar CPU, the Switch 2 will be faster as it's offloading things like compression to a fixed function block.
As for the TDP argument, it's irrelevant. Chips operate on a voltage curve. You can have a single chip go from 10w to 1,000w if you want.
And again... You need to look beneath the black and white paper specifications of hardware and get a more nuanced, low-level understanding.
