The story
A leak about a handheld console reportedly in development at Sony (dubbed the “PSP3”) has stirred up 5ch’s Hardware & Industry board (Geha), claiming a late-2027 release, PS5 game compatibility, and 24GB of memory.
The information is attributed to data miner Kepler L2, but the thread quickly filled with technical skepticism — comments like “the PS5 has 448GB/s of memory bandwidth, but the LPDDR5X used in handhelds tops out around 200GB/s, there’s no way this can run” and “a 4-core CPU is going to make developers hate this thing.” Plenty of posters also had fun guessing at price and battery life, but the real center of debate wasn’t whether the leak itself was true so much as whether such a device could actually be built at all.
What people said
How much is this thing gonna cost?
Like $899 or something?
Obviously there'll be a Japanese version too
But won't memory be even more expensive by next year?
Do the fanboys want to see Sony go under or something?
Guessing it'll run about ¥250,000
If it comes in at ¥200,000 that'd be a steal
"Native PS5 support!" (leak) → ???
Totally unrelated to the video, but ten years from now the only game companies left will probably be Steam and Nintendo, right?
That's pretty wild.
The exact opposite rumor is floating around too — Kepler L2 himself says turning this into an actual product is close to impossible from a business standpoint
Because of the memory crunch, it's become impossible for Sony to sell a portable PS6 for $600

If you trace Kepler L2's actual statements closely on overseas forums (like NeoGAF),
all he's really said is that "Sony is testing a chip with this configuration (24GB LPDDR5X),"
he's never flatly declared that a new handheld will 100% ship.
In fact, more recently he's leaned negative, saying "memory prices have surged so much that making this a real product is nearly impossible from a business standpoint."
Running a GDDR6 PS5 off LPDDR5…?
That lie is so bad it's funny (lol)
No way that thing's the "obvious answer"…
They've been trash-talking the Switch 2's 256GB, so this better top it, right?
Obviously it'll pack something like 2TB
how are they even going to run that?
Even today's high-end mobile gaming PCs fall overwhelmingly short:
ROG Xbox Ally X
LPDDR5X-8000
128-bit
128GB/s
ROG Ally X
LPDDR5X-7500
128-bit
120GB/s
GPD WIN Mini 2025
LPDDR5X-7500
128-bit equivalent
120GB/s
ONEXPLAYER X1 8840U
LPDDR5X-7500
128-bit equivalent
120GB/s
AYANEO 2S 8840U
LPDDR5X-7500
128-bit equivalent
120GB/s
Steam Deck OLED
LPDDR5-6400
128-bit
102.4GB/s
ROG Xbox Ally
LPDDR5-6400
128-bit
102.4GB/s
Even if they somehow made it work, it'd cost a fortune
Rumor says it's 192-bit
but even then it only gets to about 200GB/s
Maybe they'll add Infinity Cache?
That would make the die size a lot bigger though
I mean, there's not a single multiplatform game that runs on PS5 but fails to run on the ROG Ally
so if third parties put in the porting effort, it should be doable, right?
IF third parties put in the effort (lol)
It'd be hilarious if this thing turns out to be junk that also caps at 10W (lol)
It'll probably carry a battery around 80Wh, four times the Switch 2's
though the weight is going to be insane too
A handheld that runs PS5 games
This is the power of 3nm
Switch 2 got totally left behind for going with an outdated chip
I don't think they'd run that kind of business model
I think it'll be pay-to-play only, freeloaders excluded
After all, it'll launch with thousands of games already available, so there's no need to prop up the lineup or discount anything
Games like GTA6 that only run at 30fps are probably a lost cause
it's only got a 4-core CPU anyway, so it's not running at full clock
GTA6 runs on the Xbox Series S (XSS), doesn't it?
If third parties put in the work, it'll be fine
Developers are going to hate being asked for native PS5 support with that
For "Ongi" devs, Sony's low performance is a blessing, get it? (term unclear in original)
But Xbox Series S doesn't count, understand?
If Rockstar manages to pull off 60fps on PS5, I think a port would be possible
though at that point it'd probably get ported to the Switch 2 too (lol)
Plenty of PS5 games run at just 30fps
but is there really any game that's 30fps on PS5 and still can't run on the ROG Ally?
How many titles are actually capped at 30fps max?
Most PS5 games hit 60fps in performance mode
and the ROG Ally has an 8-core CPU
Canis (the rumored codename), with only 4 cores, is at a huge disadvantage
They probably just want to become Steam
because they're idiots
that's why they're even dropping discs, one of the console's advantages
though if they do release it, it'd be fun from a console-war-forum (Geha) perspective
There's the Vita precedent though…
Background and Key Points of This Topic
This leak traces back to information attributed to data miner “Kepler L2.” However, as pointed out in >>26 within the thread, Kepler L2 himself only said that “Sony is testing a 24GB LPDDR5X chip” — he never flatly confirmed the product will actually launch, and has recently leaned skeptical, citing soaring memory prices as a reason it may be “difficult from a business standpoint.” That gap in tone is what’s driving the split opinions in the thread. On the technical side, the focus is memory bandwidth: the PS5 itself uses GDDR6 at 448GB/s, while current handheld gaming PCs (like the ROG Ally and Steam Deck) only manage around 100-130GB/s with LPDDR5X. Skeptics argue this makes it hard to replicate the PS5 experience on a handheld. There were also comments noting that a reported 4-core CPU looks weak next to competing handhelds, most of which run 8 cores. Readers should keep in mind that price and release date remain unconfirmed rumors, not reported facts.
