The PS4 has an ARM chip with 256MB of its own memory and works fully independently to give fantastic stable online play as does the Xbox One series with its south bridge chip. |
Umm.
The Switch 2 uses a "SoC" known as a "System on a Chip". That "System on a chip" is known as Tegra Orin.
Tegra Orin has a block on the SoC dedicated to handling networking operations known as the "MAC" or "Media Access Controller" for 10/100/1000 BASE-T Ethernet MAC capabilities.
It also has a block known as the "CAN FD Controller" for communication in automotive industries.
Here is the datasheet for the Tegra chip so you can update your understanding of what the SoC is actually capable of. https://connecttech.com/ftp/pdf/jetson_orin_nx_datasheet.pdf
Rest assured all modern ARM SoC's offload network processing onto a dedicated processing block, no external chips required. Doing network processing on CPU cores is a last century idea and drives up power consumption and latency, which is literally the opposite of the design goals that ARM SoC's strive for.
Sony was inefficient with the PS4, hence the external DRAM and ARM Cores, something the Xbox one didn't have, but this wasn't for network traffic itself, it was for managing background tasks and social functions. Microsoft did it with less overhead on the Jaguar cores and system DRAM. - Both consoles had a south bridge to assist with managing I/O and networking as this is a holdover from PC designs.

I'm certainly not saying anything controversial, Virtuos stated the CPU performance is at PS4 level (not pro) for the Switch 2. I'm actually stating going by the passmark score of 2000 that it is slightly above that as PS4 scores around 1700. Maybe with reduced cache it scores a bit less than 2000 because that benchmark was on 5Nm but I wouldn't of thought much less myself as they are only run at 1Ghz anyway and normally ARM A78s can go up to 3Ghz on 5Nm. |
Keep in mind that the Playstation 4 also had 65% higher CPU clock than the Switch 2.
The Switch 2 cores themselves, clock for clock are absolutely superior to the Playstation 4... But we also need to remember that the Switch 2 SoC is doing more offloading of the CPU than the Playstation 4.
For example... Developers on the Playstation 4 would need to use the CPU in order to perform decompression tasks, the Switch 2 has a LZ4 decompression block on the SoC that takes that CPU load away, meaning more limited CPU cycles are available for actual gaming.
You need to start looking past the raw paper specs and start looking at the big picture, the Switch 2 SoC is capable of doing more, with less than the ancient Xbox One/Playstation 4 hardware... And the games are showcasing that, often returning better results... Imagine in another 7 years when developers have learned more about the hardware?

It's interesting to see Oblivion Remastered come to the Switch 2, in what seems to be a reasonable state, despite the SW2's very weak CPU. That was one game I was a bit concerned about not working well. I also don't think the 8th Gen consoles could've ran it well. An FX 8300 (and most 4-core; 4-thread i5's) are a stutter-fest when playing this game. I have an i5 4690k + RTX A2000 itx build with DDR4 2400Mhz ram that I use for light image segmentation, and out of curiosity I installed the game on that and it basically stutters every 5-8 seconds after seeming like it would work pretty well at 30fps. Very much like when people would try to play the Witcher 3 or Dragon Age Inquisition with heavily overclocked Pentium G3258's that were popular in budget builds ten years ago. The i5 4690k is on paper +30% as performant as the SW2's CPU (more if we exclude the reserved cores) so that would've seemed like it wouldn't have worked well. This also puts Virtuos's comments in perspective. They probably had to do quite a bit of work to get this ported, given the Switch 2's CPU and that is why the developer honed in on it being the bottleneck, when asked. Edit:
Also I am very impressed with FF7: Rebirth's trailer. It looks like it is consistent with Intergrade in terms of general end-result. |
Oblivion Remastered actually scales down on PC hardware super well.
It's the scripting and cell loading which causes the stutter and framerate issues, which is an I/O bottleneck and a characteristic of the Game Engine. (Gamebryo in this instance.)
I have zero concerns about the CPU/GPU being enough to run the game... Especially as I have a notebook with an RTX 2050 4GB that has returned good results. (Nothing compared to my desktop PC however.) I am not sure how it runs on the Xbox Series X/Playstation 5 though as I haven't bothered to run the game on those consoles yet. |
Tegra Orin is a SOC with up to 60W TDP meant for premium automobiles with a high cost and a huge feature set for the time. 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.
Orin
Nvidia 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:
- CPU: 12× Arm Cortex-A78AE (Hercules) ARMv8.2-A (64-bit)[161][162]
- GPU: Ampere-based, 2048[163] CUDA cores and 64 tensor cores1; "with up to 131 Sparse TOPs
of INT8 Tensor compute, and up to 5.32 FP32 TFLOPs of CUDA compute."[164]- 5.3 CUDA TFLOPs (FP32)[165]
- 10.6 CUDA TFLOPs (FP16)[165]
- Samsung 8N process (derived from 8LPU)[165][166]
- 275 TOPS (INT8) DL[165]
- 170 TOPS DL (INT8) via the GPU
- 105 TOPS DL (INT8) via the 2x NVDLA 2.0 units (DLA, Deep Learning Accelerator)
- 85 TOPS DL (FP16)[165]
- 5 TOPS in the PVA v2.0 unit (Programmable Vision Accelerator for Feature Tracking)
- 1.85 GPix/s in the ISP unit (Image Signal Processor, with native full-range HDR and tile processing support)
- Video processor for ? GPix/s encoding and ? GPix/s decode
- 4× 10 Gbit/s Ethernet, 1× 1 Gbit/s Ethernet
1 Orin uses the double-rate tensor cores in the A100, not the standard tensor cores in consumer Ampere GPUs.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.
