PlayStation 5 teardown: how Sony balanced build cost with performance

Advertisement


Final week, Sony lastly unveiled its teardown of the PlayStation 5 console, fulfilling a promise first made by Mark Cerny over six months in the past in his personal Highway to PS5 presentation. Successfully a primary define of the make-up of the {hardware}, we lastly obtained to see the elemental constructing blocks of Sony’s hulking console, however little was revealed by way of the philosophy behind the outstanding design. Our take? It is a considerably extra typical design than Xbox Sequence X, and the important thing challenges dealing with the designers are answered by sheer actual property.

Yahuhiro Ootori, VP of the mechanical design division at SIE is the stoic presenter of Sony’s teardown – and he is the true deal, with a number of console patents to his identify (probably the most not too long ago unearthed being the PS5 dev package) and naturally, he additionally hosted the PS4 teardown video means again in 2013. His presentation begins with a primary define of the port on the unit – a USB Kind-A and 10Gbps Kind-C on the entrance of the unit, paired with two 10Gbps Kind-As on the rear, the LAN port and HDMI 2.1 output. We’re hoping that affirmation of 10Gbps of bandwidth over USB ought to permit for some quick storage media choices for back-compat titles, maybe exceeding the outcomes we have seen on Xbox Sequence X. In the meantime, in revealing the rear ports, the sheer dimension of the venting right here hints on the scale of the thermal answer to return.

Ootori appears to virtually ‘peel again’ the white panels both facet of the console earlier than pulling them away. Below there, we get to see the twin inlets for the customized 120mm predominant fan. In fact, 120mm is an ordinary with regards to constructing PCs however the 45mm depth of the customized unit is one thing else. It is also right here the place we see ducts designed for customers to hoover out extra mud that would clog up the cooling meeting. This was a significant failing for PS4 and contributed to its growing loudness of time and it is good to see this addressed with out having to dismantle the unit and void the guarantee – as was the case for the PlayStation 4 and PS4 Professional.

As soon as the WiFi and Bluetooth antennas are eliminated, shielding is taken away and we get our first have a look at the mainboard – a considerably less complicated setup than the Microsoft Sequence X equal, which truly splits the entire design into particular person processor and southbridge boards. There’s just one board with PS5, the reminiscence system is way much less complicated, and the board hardly appears packed by comparability. That is the place we get our first have a look at the SoC (system on chip) – the principle ‘brains’ of the system. Ootori himself describes this as a small, however extremely clocked processor utilizing a liquid metallic thermal interface to make sure an optimum switch of warmth between the chip and the cooling meeting. This ticks off one other noteworthy revision over PS4 and Professional, each of which have been hardly famend for the standard of their thermal grease.

A video breakdown of the latest Sony PS5 teardown.

The scale of the SoC is attention-grabbing and infrequently indicative of points of the design comparable to transistor depend – to not point out having an enormous price implication. Some on-line dialogue suggests a 308mm2 chip, primarily based on comparability to the GDDR6 structure seen round the principle processor. With no square-on have a look at the chip, and no direct comparability factors evident, getting a agency lock on the world of the processor is difficult, however one thing within the 305mm2 to 320mm2 appears doubtless when in comparison with Xbox Sequence X. Right here, now we have a completely annotated die shot and a confirmed space – stripping again 16 compute models and a few GDDR6 reminiscence controllers actually places us in that ballpark. In comparison with the Sequence X, the entire setup right here by way of the processor and the reminiscence represents a big price saving.

The teardown additionally affords us a have a look at the SSD – constructed into the motherboard with the controller chip surrounded by NAND flash modules. The 5.5GB/s of uncooked bandwidth (even earlier than factoring within the further increase provided by {hardware} decompression) is a matter of report now – my solely concern being that repairability and sturdiness of SSDs are nonetheless one thing of a query mark. A faulty console SSD principally makes restore inconceivable, past returning the unit to Sony. The M.2 storage growth bay can also be revealed – that is the place the newest era of PCIe 4.0 NVMe drives ought to have the requisite bandwidth to match Sony’s inside answer, permitting off-the-shelf SSDs to be added for further storage. The improve process appears easy sufficient, however these drives can get sizzling and I do marvel how the system goals to chill them – it isn’t clear from this video how this achieved.

The teardown ends with a have a look at the ginormous heatsink and a meaty 350W energy provide (count on precise energy draw to be loads, lot decrease). It is fairly clear what Sony’s technique is right here with {hardware} design: to maintain prices manageable with a small processor, however enhance efficiency by blasting it with a excessive degree of energy, diverted to CPU and GPU frequencies as wanted. Dissipating the warmth is all right down to what I might take into account an virtually Toyota-like philosophy – to not reinvent the wheel (in the best way that Microsoft has with Sequence X maybe) however to depend upon what works and so as to add some further thrives the place wanted. The value we pay comes by way of sheer quantity: that is clearly going to be an enormous console, comparatively talking, however the benefit to Sony is a substantial discount in construct price.

Japanese influencers have been hands-on with the system and its silent nature has been commented upon – and I will actually have an interest to see how that each one stacks up as soon as we’re palms on with the {hardware}. Hopefully, that will not be too lengthy now…
