PS5 Rough CPU

[WizKid]

Now we all well know that the processor in the base PS4 is based on the Athlon 5150.

Are there ideas about what AMD processor the one in the PS5 is based on?

I would image that the equivalent processor won't come out until next year, seeing as how the Athlon 5150 didn't come out until 2014.

Are there ideas about what AMD processor the one in the PS5 is based on?

PS5's CPU is based on the Zen2 Ryzen 7 3700, but is fully custom, Clocks are lowered to reduce TDP but core count is the same and SMT [Simultaneous Multi-Threading / or Hyperthreading as its called by Intel] is available on the PS5 BUT its up to devs if they want to use that in games as its NOT enabled by default.

I would image that the equivalent processor won't come out until next year

A better one has already been released by AMD > Zen3 Ryzen 5700 was launched last month irrc and AMD has also launched the RDNA2 Radeon 6000 series GPUs [ 6800 and 6800XT ] which is what the PS5's is based on which is better than a RTX 2080super BUT not better than an RTX 3080 or 3090 but wipes the floor with the RTX 3070.

Zen3 Ryzen has aslo kicked Intel from the Top spot in the CPU race performance wise. And they are now giving Nvidia a good run for there money in the GPU race.

So all-in-all you might be getting a last gen AMD Ryzen 7 based CPU in the PS5 BUT it is still more than capable of giving gamers a great gaming experience at the mid-level PC point. And for the price.... well that just sweetens the deal as a PC would caost close to £1000 to build fro these specs.

Yeah, is based in Zen2, but there are a bunch of differences with retail AMD APU's, some that worths to be mentioned...

The Hardware Raytracing features present in the standard RDNA2 has been adjusted very well to the PS5... in the sense that has been reduced to the "sweetspot" the sony engineers considered that made sense for a console
With this i mean... if you take a look at the power consumption of the Nvidia graphic cards with raytracing you are going to see that actually is very demanding, when you enable a powerful raytracing "by hardware" in nvidia graphic cards the fps are reduced a lot... up to a point where is not worthy
In my oppinion this is a consequence of the hardware raytracing being a technology that is very recent and needs to be ballanced
It looks sony and AMD engineers was very careful with this... it will be needed some time (years) and several games to see if what they did was good enought

The Tempest 3D audio is also made by hardware, using a CU of the graphic block dedicated to it... this means is "offloading" the workload in the main CPU, you know... by doing it this way you still have 100% of the CPU for other tasks
The XBOX X have his won 3D audio but is done by software (is an additional task in XBOX CPU)

The Kraken decompression engine is also a dedicated controller (again is offloading the CPU). The XBOX needs to do it by software (is an additional task in XBOX CPU)

There are controllers for the SSD and RAM (seems to be micro-processors based on ARM architecture)

-----------
This features are PS5 exclusives, all them are nice for a console and are a bit revolutionary
We could argue that the hardware raytracing is a "low quality" in comparison with the XBOX X or PC, but thats still not clear at all
And we could argue also if it was worhty to "waste" all that space inside the APU for all this exclusive hardware features... obviouslly this is the reason why the PS5 APU have less graphic cores than the XBOX... but i think all and all... is a nice APU design

Btw, the 3D tempest audio is in his first steps, cerny mentioned that they are trying to prepare some "audio profiles" (based in the phisical geometry of the person head and ears) to cover all the world population
And you know... thats imposible technically, lol, but is going to work good enought
I remember to try a 3D audo experimental demo years ago in some web that i forgot, without any settings, with cheap heaset... and it was awesome
I know this kind of technology added with 5 or 10 "audio profiles" to allow you to configure it a bit for your preferences and used inside videogames is going to be very impressive
I can imagine a survival game horror like silent hill with that sountrack of loliness hearing noises at the far away, or an enemy at your back literally "blowing in your ear"... it could make some people poop his pants, lol

The real challengue they have with the 3D audio is the idea of using it with the speakers of the TV... this is going to be tricky and im curious about the result
The problem is the speakers are not located in your ears, actually they could be located a very different distances for every PS5 owner, they are going to need to implement also some kind of "audio profile for speakers"... but even with this profiles im not so sure about the results
I have serious doubts if is posible to create a 3D audio only with the 2 speakers of the TV

With a 5.1 audio system, and the speakers correctly located all around the room then yeah... is going to sound nice

PS5's CPU is based on the Zen2 Ryzen 7 3700.
...but wipes the floor with the RTX 3070.

Seems like you're right, and Amazon quotes a price of roughly $1,279.98 USD (as seen above) for roughly the same specs.

That is, assuming the person selling the 3070 isn't price gouging. In which case, you're probably correct price-wise.

That price is too high, the OG RTX 3070 from Nvidia MSRP is only £500. SO that card from Gigabyte should only really be about £200 MAX more than Nvidia's FE, if it was an ASUS ROG SRTIX or GB Aorous version of the RTX 3070 then maybe the price could be justified but people are driving the price up because they are very hard to get a hold of atm because of COVID.

MSRPs
Nvidia > RTX 3070 £500, RTX 3080 £700, RTX 3090 £1000 [ this is a TITAN level GPU which is why the price is so high ]
AMD > Radeon RX6800 £530??ish, Radeon RX6800XT £670??ish

These are just from what I remember off the top of my head, RTX cards for FE version are right, not 100% sure on the AMD's Radeon RX but they are close to that. I know one of them was more expensive then its competing Nvidia card and the other was cheaper, I think I might have the AMD ones backwards tbh.

I am only keeping an eye on it as I am after the new AMD Ryzen 9 5950X and an RTX 3090 FE, but prices and availability are al over the place atm... Also the new AMD cards are good but not good enough for me to go from Nvidia to AMD on the GPU side just yet as I won't be getting a PS5 anytime soon, I have used one and they are quite good but I have went back to PC gaming mainly.

Also remember that the PS5s GPU is more or less based on the RX6800 so is a lot better than an RTX 3070.

Btw, the PC APU's most similar to the PS5 APU are the "renoir" 4000 series for "mobile" devices (in other words, for laptops)
Are the models with a "U" suffix in his name
https://en.wikipedia.org/wiki/List_of_AMD_accelerated_processing_units#"Renoir"_(2020)_2

The other 4000 series renoir APU's for desktop PC has not been released for retail, only OEM for hardware assemblers, are not for sale in standard shops.... but you can find them at the black market (shops from hong kong, and are sold at abusive prices)
This are the ones with a "G" suffix in his name
https://en.wikipedia.org/wiki/List_of_AMD_accelerated_processing_units#"Renoir"_(2020)

Anyway... as mentioned above there are many differences with the PS5 APU, another difference that worths to be mentioned is this APU's for PC have a PCIgen3 controller (because it seems it requires a lot less power than PCIgen4)
AMD decided to stay in PCIgen3 in his APU's for some time before doing the "jump" into PCIgen4
And sony requested to AMD to implement a PCIgen4 controller in the PS5 APU... because the considerations about designing a "low power" console are relative

You know... from the point of view of power, a desktop console is something in between, the laptops with a 4000 series "U" renoir APU are going to be around 20W TDP (and in the next revisions AMD will continue reducing it)
And the PS5 APU... dunno, but i guess is going to be around 50W or more




-----------
Edit:
Also, this APU's for PC are still using VEGA grafic cores (not RDNA2), because the same reason mentioned above... VEGA is more power efficient and AMD doesnt wants to do the "jump" yet in his retail APU's

Compare how it looks the ryzen 4000 series "mobile" APU's with the PS5 APU

https://www.anandtech.com/show/1562...he-ryzen-mobile-4000-series-7nm-apu-uncovered

Is the same "monolithic" design with everything inside the same DIE (I/O controller, CPU cores, and GPU cores)
AMD has been using this concept of a monolithic design in his APU's since the first zen1 series years ago, and they has been always using the best technology they had available
So... the PS5 and XBOX APU's was a "fork" of this same technologies... is just sony asked AMD to spice it a lot, lol
