Portable PS5? *spawn*

[RDGoodla]

Strix Point reveals and has ZEN5 or 5C, RDNA 3 GPU and next-gen NPU. Again it uses 4nm process.

Sony may not want to spend too much on a handheld console so it is likely Sony uses a variant of Stirx Point.

Generally Sony tends to use the same number of cores for last-gen games . 8 cores CPU and 18 cores GPU are needed. 8 cores Zen 5C is power efficient and more than enough to emulate 8 cores Jaguar. 18 cores RDNA 3.5
at 800 MHz is enough for 1.8 TFs.

Pro aside, do you think it's possible to hit 20w apu with zen 2 4/8 at 1.6 GHz and 18cu rdna2 at 800 MHz for hypothetical PS4 portable?

Depends on the process node. 7nm? No. Maybe on 2-3nm.

Anyways, the "PS4 portable" rumours have always been improbable. They aren't making a portable that plays just PS4 games locally in 2027-2028.
They want users to buy new games, not 10 years old games.

If a portable comes out together with the ps6, it's going to be compatible with ps6 games (with developers making downgraded versions of ps6 games coming out the same day), it would get patches for PS5 only games and be retrocompatible with PS4.

Developers are going to be supporting the switch 2 in droves, and the deck 2-3 is going to run most of those games. Downgraded versions are going to be made regardless.

All the specs are definitely achievable, including the trickier part of getting 176GB/s of bandwidth and a sufficiently fast storage solution. The real trick though, would be doing all this in a cheap APU and affordable overall product. Cuz nobody is gonna want to spend $400+ on a portable, digital-only PS4 in the year 2025.

Something like the basic Steam Deck makes a lot more sense and would be hard competition, even if it lacks the raw GPU horsepower and bandwidth of PS4 for full 1080p play in a lot of these games. You still get access to like 98% of PS4's library, including a large chunk of the 1st party titles. But you also get so much more. Main downside would be that you couldn't just transfer over any existing PS4 digital library, so you'd have to buy games again. But most all PS4 era titles are pretty cheap these days...

The 4nm APU has 8 cores Zen 4 at 1.2 GHz and 12 CUs at 1.5 GHz with 15W power. The APU is better than PS4.

Using 20W the APU may have the performance of Switch 2 portable mode. Playing PS4 games may need 10W.

The cheapest solution is probably AMD strict point. Using 10.7 Gbps LPDDR 5X the PS handheld can port Switch 2 games and run all PS4 code.

This really isn't a 'cheap' solution, though. Cheapest maybe, in relative terms, but such a device would need to be properly affordable to be worth it. Nobody will want to spend $400-500+ on a portable PS4 system.

And whether it can technically play Switch 2 games is irrelevant, since we're talking about a portable PS4 and all that involves. This isn't a PC, this is a PS4. Unless devs port such games to PS4, it wont be on the system.

If Sony makes a PS4 portable in 2028 they are officially out of their minds.

I don't think anyone is suggesting that Sony release a portable device that only plays PS4 games, but rather a portable that can play games specifically made for it along with PS4 games. Plenty of people were willing to pay $200 for the PlayStation Portal, which has no other purpose than to allow you to play games on your PS5 while being in a different room of your house. Another device that does the same while also playing games specifically made for it, PS4 games, Vita/PSP games, and supporting PS Plus streaming will be successful if it can hit the $400 price point. If it can run Android apps sold through the PlayStation Store then that would be even better. It would still be a niche product, but not a flop.

Sony handheld console is just like Nintendo Switch 2, which is a new handheld console and it can play Switch 1 games.

PS5 exclusive games are likely to port to the handheld console. And Porting Switch 2 games should be easy.

AMD's Ryzen Z2 Extreme will hit next-gen gaming handhelds in 2025

In an IFA roundtable, AMD confirmed that its next-gen Z2 Extreme chip for gaming handhelds is coming sooner than later.

Strix Point handheld SOC coming in early 2025


Sony handheld console just only needs 8 cores Zen 5c at 2.5 GHz to match PS5 CPU. It may use 170GB/s LPDDR 5X and have 18 ~ 20 CUs. It is very interesting Strix Point have a NPU so it may be possible to run simplified PSSR for 1080p.

This specs can run PS4 codes directly and porting from xb series s then upscaling to 1080p using PSSR.

I wonder if they have added a system call in the SDK to reduce the resolution of games without having to patch them.

The CPU in 2028 shouldn't be a problem at low wattages, but the GPU for PS5 games would require them to go game by game and cut the res in half for most of them. If they can do that, I can see this happening.

540p on a portable screen doesn't look too bad.
