Even 3nm portable playstation from holidays 2028 wont be strong enough to match 7nm ps5 from 2020, for the simple fact that 220W actual powerdraw in games cant be decreased enough with such a tiny difference of manufacturing process, portable will likely be at 20w powerdraw or less so its at least 10x difference, tldr, simple math and physics makes it impossible, maybe by ps7 tho...?

Good luck cooling a 35w-50w portable
Click to expand...
Virtually every handheld released in last 3 years has a cooling assembly that handles 35W APU just fine (so around 45-50W total system dissipation).
Anything higher would be pointless with batteries capping out at 80Wh.

I think bigger problems are elsewhere though - memory's been stuck in sub 100 GB/s land for a long time now. Probably the only cost effective way that doesn't also blow the power budget would be an APU with sizeable amount of eDram.
That Strix Halo video is actually making projection look worse (since even at full 120W the system isn't quite there).

By 2028? I would think its not an issue.

Nvidia architecture needs a shitload of RAM Bandwidth but the hit doesnt seem to be as big on AMD, given that they put GDDR6 on the 9070 (xt) not GDDR6X or GDDR7.

📌 Can a PS6 Portable Be as Powerful as a PS5 by 2028?​

✅ 1. CPU (Processing Power) – Yes, Likely​

  • PS5: 8-core Zen 2 CPU @ 3.5GHz (~448 GFLOPS CPU power)
  • PS6 Portable (~2028 Expected): 8-core Zen 5/6 CPU @ 3.0-3.5GHz (~600+ GFLOPS CPU power)
💡 Verdict: Yes! By 2028, portable chips will be much more efficient. An 8-core Zen 5/6 CPU could match or outperform PS5’s Zen 2 CPU while using far less power.

✅ 2. GPU (Graphics Power) – Possibly, Depending on TDP​

  • PS5: 10.3 TFLOPS RDNA 2 GPU (36 CUs @ 2.23GHz)
  • Steam Deck (2022): 1.6 TFLOPS RDNA 2 GPU (8 CUs @ 1.6GHz)
  • ROG Ally (2023): 3.8 TFLOPS RDNA 3 GPU (12 CUs @ 2.7GHz)
  • PS6 Portable (~2028 Expected): 6-10 TFLOPS RDNA 5+ GPU (~20 CUs @ 2.5GHz?)
💡 Verdict: Maybe.

  • A 6-10 TFLOPS GPU in a 30-50W handheld is possible with RDNA 5+ or AI-assisted upscaling (FSR 4.0, AI reconstruction).
  • But it won’t be exactly 10.3 TFLOPS like PS5 unless Sony pushes higher power consumption (50-60W docked).

✅ 3. RAM (Memory & Bandwidth) – Likely​

  • PS5: 16GB GDDR6 @ 448GB/s
  • PS6 Portable (~2028 Expected): 24GB LPDDR6X @ 400-500GB/s OR LP-HBM @ 800GB/s
💡 Verdict: Yes!

  • LPDDR6X (expected ~2026) could provide 400-500GB/s bandwidth, nearly matching the PS5.
  • If Sony uses LP-HBM (~800GB/s), it would surpass PS5 in memory bandwidth!

✅ 4. Storage – Faster than PS5​

  • PS5: 5.5GB/s SSD (9GB/s compressed)
  • PS6 Portable (~2028 Expected): PCIe 5.0 SSD (~10GB/s)
💡 Verdict: Yes! A PCIe 5.0 SSD in 2028 will be at least 2× faster than PS5’s storage.

✅ 5. Power Consumption – Portable vs. Console Tradeoff​

  • PS5: ~200W+ TDP (console)
  • PS6 Portable (~2028 Expected): 35W-50W TDP (portable mode), 60W+ docked mode?
💡 Verdict: It depends on power limits.

  • In handheld mode (~35W-50W), the PS6 Portable may run at ~6-8 TFLOPS.
  • In docked mode (~60W+), it could hit PS5-level performance (~10 TFLOPS).
  • AI upscaling (FSR 4.0, DLSS-like tech) can compensate for lower raw power.

📌 Final Answer: Will PS6 Portable Match PS5?​

ComponentPS5 (2020)PS6 Portable (~2028 Expected)Can it match PS5?
CPU8-core Zen 2 @ 3.5GHz8-core Zen 5/6 @ 3.0-3.5GHz✅ Likely better
GPU10.3 TFLOPS RDNA 2 (36 CUs @ 2.23GHz)6-10 TFLOPS RDNA 5 (~20 CUs @ 2.5GHz?)🟡 Maybe (~6-8 TFLOPS portable, 10 TFLOPS docked)
RAM16GB GDDR6 @ 448GB/s24GB LPDDR6X (~500GB/s) or LP-HBM (~800GB/s)✅ Likely equal or better
Storage5.5GB/s SSDPCIe 5.0 SSD (~10GB/s)✅ Likely faster
Power (TDP)200W+35W-50W (portable), 60W+ (docked)🟡 Depends on TDP

📌 Final Verdict:​

✅ A PS6 Portable in 2028 CAN match or exceed the PS5 in most areas, but it depends on power limits.

🚀 Possible Performance Modes:​

  • 🟢 Portable Mode (~35W-50W): 6-8 TFLOPS (PS4 Pro+ to near-PS5 performance)
  • 🟡 Docked Mode (~60W+): 8-10 TFLOPS (matching PS5 with better RAM & SSD)
  • 🔴 Full PS5 power (10.3 TFLOPS) in handheld mode? Unlikely, unless power efficiency drastically improves.
——————————————————

By next-gen, we will have cross-gen games and probably 99% of games will be built with PS5 as the least common denominator. With that in mind, PS6 at 50w tdp at $449 that is small enough to be portable and can be attached to a separate sort of PS portal machine (controller+screen+battery) would be a great idea! PS6 base will be cheap and PS6 Pro will be the 200w-300w monster machine.

I think, Sony should focus on PS Portal 2
(direct WiFi connection!).

Leave a dedicated handheld to Valve and Microsoft, which both have better starting positions in this department.

It won't match the PS5's power due to energy, cooling, and efficiency limits. Even with advancements, a handheld must balance performance, battery life, and heat dissipation, making full PS5-level power impractical. At best, it may reach a lower-power PS5 mode, similar to how the Steam Deck handles PS4 games.

That's funny. I asked Chat GPT and it gave me a different answer OP. It's almost like asking AI this kinda stuff is dumb.

If Sony made a PS6 Portable, it could probably get close to PS5 performance, but not match it exactly. Here’s why:


1. Tech Advancements Make It Possible​


  • By the time Sony would develop a PS6 Portable, we’d be at least five or more years into the PS5's life cycle.
  • AMD (who makes the PS5’s CPU/GPU) will have more efficient, smaller, and powerful chips.
  • The Steam Deck and ASUS ROG Ally already show that portable gaming PCs are catching up to last-gen consoles.

2. Power vs. Portability Trade-off​


  • The PS5 draws around 200W of power, which is way too much for a portable device.
  • A PS6 Portable would need a custom, power-efficient chip, similar to how the Steam Deck uses a custom AMD APU.
  • Even the most efficient laptop GPUs today struggle to match PS5 power within a small, battery-powered device.

3. Battery Life & Heat Issues​


  • To be truly PS5-level powerful, it would either have a huge battery or be plugged in most of the time.
  • Heat dissipation is a major issue—PS5 is big because it needs a large cooling system.

4. Performance Scaling​


  • Sony could use DLSS-style upscaling (like NVIDIA’s DLSS or AMD’s FSR) to make games look close to PS5 quality on a lower-power chip.
  • They could also use dynamic resolution scaling, dropping the resolution when needed to maintain smooth performance.

Conclusion: Near PS5 Power, But With Limitations​


A PS6 Portable could probably reach around 80-90% of PS5’s performance, especially with upscaling techniques. It would likely target 1080p instead of 4K and focus on power efficiency rather than raw power.


Sony could also go the cloud gaming route, making it more like a hybrid of a portable and a streaming device, but that depends on how good internet infrastructure is in the future.


Would you want a fully native PS6 Portable, or would you be fine with a hybrid streaming system like the PlayStation Portal but with actual local play?

GDDR6, GDDR6X, or GDDR7 is too power hungry to be put in a 50w PS6. That’s why it’s the bandwidth that I think will fall short.

Well, that’s why I was suggesting that the device is a separate PS6 sold without oked screen and battery.

But a peripheral like PS Portal with large battery and Oled screen can be bought as a peripheral.

Don’t think switch. Think laptops. 20,000 mAh batteries with oled screen. 20,000 mAh portable batteries I could get for around $100.

We have 65w and higher laptop. What makes laptop expensive is that it’s integrated with cooling, screen and large batteries.

A 50w machine can be portable.

Think 50w. The RAM bandwidth has to eat a lot of power to match 400gb/s.

This is not what the fans have asked for. If Sony in fact do release a PS6 handheld the fans will want absolute hardware parity (which of course will not be possible) otherwise it's another Series S situation.

I think we’re in a point in game development that more power will just give us higher resolution and fps. I think PS5 will stay relevant during PS6 era.

To have truly next gen machine, PS6 will be very expensive. Sony has to have a cheaper alternative. Yes, short of like Series S.

While were at it, make it portable to cushion the blow. $449 with screen and battery and as powerful as PS5 in all parameters (except perhaps GPU) to ease the pain of porting from PS6 to this device.

Yes, I’m also thinking the problem would be RAM bandwidth.

With a slightly weaker GPU, a port from PS5 wouldn’t be as difficult. Lowering the resolution can do the job. But if the RAM bandwidth is not up to par, it will introduce more complications in porting.

In 2028, theoretically, a handheld using 2025 desktop technology (Zen 5 / RDNA4) scaled down can pull 10 tflops at 30watts of usage on 12 CU.

RDNA 4 9070 XT @ 48.66 Tflops @ 320 watts of power with 2028 (+3 years) fab refinements and adjust the over whelming power draw down to an undervolt will be able to do it.

However, in 2028 AMD will be on UDNA tech and retired RDNA so who knows by then.

I mean Steam Deck is using Zen2 (5 year old tech) and RDNA 2 (4 year old tech). It is completely feasible to see Zen 5 and RDNA 4 in a 2028 handheld.

CPU is doable, GPU is a maybe, but the big problem is memory bandwidth. Even LPDDR6 tops out at 230GB/s. I suppose a 256bit bus can bring that up to 460Gb/s, but that runs into battery life issues.

You asked the question wrong.
AI gave you its prediction for 2028, but to release in 2028 you should have asked its prediction for early 2027, to account for prototyping and mass production.
There is also the battery issue, it will be ultra expensive if you need a heavy battery backpack to play it...

No. Because it doesn't matter what hardware is available in 2028, it matters what hardware is available next year. You don't just decide to make a product and ship it the next day, hell if you could do that the XSX and PS5 would have shipped with better hardware.

Bro, just look at total powerdraw, 220W measured durning gameplay, 2020 ps5 was already on 7nm node.
We can expect holidays 2028 ps6 on 3nm node since even now crazy expensive 50xx nvidia cards are on 5nm(despite clever naming), same with amd cards that just launched...

Again, the device will be without oled screen and battery.

Think of a 50w laptop with no screen and battery in a thicker but small dimension shell.

The screen and big battery (I see fairly small and compact 20,000 mAh batteries btw), will be sold as a separate device similar to PS Portal.

That’s why I was thinking this 50w PS6 can hit $449 instead of $700.

PS6 Pro will be 200-300w next-gen monster launching at the same time for $899!
