AMD Working On Stripped-Down PlayStation 4 SoC for PCs

[Shihab]

In what world.

If a SoC was powering PS4. ARM should be out of business.

AFAIK, SoC isn't related to low power consumption alone, nor performance. Like the guys said, stick a CPU, GPU, IMC, and any other chips/controllers/etc into one chip and it'll be a SoC -by definition- regardless of how much power it draws or how much flops it can crunch.

ARM will still pwn the business as it currently has the best power consumption. But that's for the Mobile segment. A PS4 is more of a PC.

On a PC it cannot because they are not optimized for it. However hes correct. The PS3 has about the same power as a 7900GT from what I remember. The 360 was around the X1900.

Yup, exactly.

If anything, it's slower: https://en.wikipedia.org/wiki/RSX_%27Reality_Synthesizer%27

The PS3 works a little different, with the Cell able to assist and aids the RSX which helps it to achieve somethings that the 7900GT couldn't.

This logic applies to consoles in general. That's why a HD7950 is not a good candidate to play "every PS4 port ever".

 

[TheMailMan78]

The PS3's RSX was actually based on the 7800GTX. But they cannot be compared direct just from GPU.

Yeah and after it was all said and done it was about as powerful as a 7900GT. The Cell doesn't magically make it a 670.

 

[blibba]

I never said the cell was comparable to high end pc. Re read my post.

I was simply saying the Cell helps the RSX to achieve certain visuals that were not possible on the 7900gt alone. Gosh you guys are quick to judge.

The Cell's benefit to the 7600/7800 in the PS3 perhaps does allow it to achieve some things that a 7900GT could not, but not much.

Essentially it appears that we agree regarding the point at hand (7950 vs. PS4), so I don't really understand why your jimmies appear so rustled.

Also, nobody's judging anyone, except you with your ironically hypocritical assertion that we're quick to judge.

Its not and I should have put a /sarcasm there.

The 2 sources that were pointed out as I quoted only one had one sentence with SoC reference that was actually a mistake and refering to a APU.

I dont know how someone makes the leap from an interview of stricly APU referances and goes on about SoCs. Making 6 referances to it. Thats what I was getting it.

It be the first SoC (APU+/+/+/+/+/+/+/+)
/sarcasm

 

[blibba]

Care to evaluate what jimmies appear so rustled?

Evaluate them? Ok, I'd say they're worth about $2.50.

And your judging me and coming to a conclusion that I'm instigating an issue.

• I don't think you're "instigating an issue"
• I would not need to judge you to decide that you were "instigating an issue"
• Judging you would not be helpful in coming to any such conclusion
• I'm not judging you, I don't even know anything about you

Anyway, this is grossly unproductive, I'm unsubscribing from the thread.

Quoting techreport:

Sony's upcoming PlayStation 4 console will feature an AMD APU that combines eight Jaguar CPU cores with integrated Radeon graphics and a shared GDR5 memory interface. The chip has also been infused with Sony technology, although it's unclear to what extent.

A normal CPU wouln't incorporate memory on die (other than its cache).
Knowing that Sony isn't an x86 CPU manufacturer, nor a GPU manufacturer. I highly doubt what's in that chip would be any of both. Hence, conforming to the SoC definition. The source may have not labeled it as such, but it is.
Now, from where I stand, neither btarunr nor the two sources are mistaken, the chip can be called either. As from what I know an APU is SoC.

Sarcasm aside, I'm interested in knowing why you believe the APUs aren't socs...

Please for feel free to. No one is forcing you to read.

APUs dont control all I/Os

Not sure if legal to fap or not. Age must be confirmed before target is acquired....over.

I agree with him. A SoC usually have a NIC and various IO (system on chip. An APU have a cpu and a gpu. It shouldnt be called a SoC imo.

Fair enough...

Then all's left is whether the actual chip used on the PS4 is a SoC or not.

So much for a welcome-to-tpu-party

Just wait until the after party!

More PS4 Specs

 

[xenocide]

More PS4 Specs

No specifics, but I'm going to predict that GPU as a 7750/70-level GPU. It would work pretty well. I just don't see them splurging for a 7800 series GPU and definitely not Tahiti.

 

[Xzibit]

Cape Verde XT (1.26 TFlops) would have to run at higher mhz to achive the 1.84 TFlops

Pitcairn is more likely 1.7-2.5 TFlops

 

[TheoneandonlyMrK]

More PS4 Specs

No fresh specs there, just what was already known, and wtf an soc this isnt, as I said many hours ago apu+nb+sb would be soc this is just another apu atm anyway .
As ive said sony had input we don't yet know What though.
Post 720 announcement these specs will expand imho

fkin' LOL

 

[cdawall]

Sorry I still don't get what you mean by the $2.50 comment
And It was not my intention for any hostility.

AMD's stock eval is right around $2.50 right now. That's probably what his comment was aimed towards.

Great time to buy IMO with the PS4 confirmed AMD and the Xbox leaning...

Would be great if both used an APU to run games. I would hope it meant console ports would be simpler and better.

I understand what your trying to say there. IF RSX is basically a 7900GT who's architecture could not take advantage of such api's as DX10/11/11.1 then why do some games on the PS3 have some of the features those api's (DX10/11/11.1) demonstrate? Well Cell is helping make sense of it to RSK.
Please correct me if I missed something.

The RSX chip is a G71 based card with as many ROP's as a 7600 and 256mb GDDR3 period end of story.

How would this processor be a win for consumers? A win for consumers would be something along the the lines of a 22nm processor that preforms better than an i5 at a lower price. The Hondo chips show a lot of potential for the evovling tablet/mobile world. Although, the Hondo chips may prove to be late to the party..

 

[NeoXF]

Just look at WATCH_DOGS... one of the few games coming out in the future that actually look "next-gen", they said it's main development platform is PC, it will also be coming out on PS4 (and PS3, which is weird but should make things interesting...).

It's very probable the a lot of the games coming out in the next years will have PC as lead platform and given the platform similarities, be scaled down or sideways or chopped into size for PS4/XBox3. Or keeping the same idea, "timed-exclusives" or console-exclusives be more inclined to also come to PC later on.

 

[mastrdrver]

Everyone does realized that a "stripped down version" of the PS4 chip is the upcoming Kabini (which is going to replace Bobcat) correct? It was even demoed at CES in the Temash tablet running Dirt Showdown.
