Asus ROG ALLY looks pretty promising. Would It be a good replacement to my i5-9300H + GTX1650 + 24GB DDR4 + 1.5TB SSD? Probably not worth It.

Advantages:
1. CPU performance would see a massive improvement, at least ST +50% and MT +150%
2. very portable, small form factor, light
3. low power consumption
4. Compatible with Steam etc.

Disadvantages:
1. IGP won't see any significant improvement compared to GTX1650, but higher Vram allocation could help.
2. I honestly doubt It will have a long battery life during gaming, but this is not that important for me.
3. 16GB DDR5 + 512GB SSD, although MicroSD slot is available
4. No kickstand
5. Windows 11
6. Need to buy additional Dock for It to connect to monitor, keyboard etc.

That s not a relevant device for laptop like usage, my point is that such a device can be sold for 700$ then it s possible to make a laptop that s below 1000$.

I'd hope that SteamOS is installable on it and plenty Steam Deck optimizations also work on Phoenix.

To be honest I'd have set the bar for "affordable" significantly lower than 1000$. But in that case RMB laptops are slowly getting there.

Going by availability in the German market:
  • Rembrandt/Rembrand-R: 237 configurations, starting at 732.26€, 21 below 1000€
  • Dragon Range: 7 configurations, starting at 2199€
  • Phoenix: 2 configurations, starting at 1990.04€

Of course, this is not good for office work without a keyboard or touchpad and small screen, but It's very portable.
I am connecting my laptop to a monitor, keyboard and mouse most of the time, so this could be an alternative to me, at least I won't need to buy a 2x costlier laptop.

Phoenix could be put into a laptop <1000$, but they most likely will put It in the more premium ones, because of limited supply.
For the cheaper ones, you will get rebranded Cezanne and Rembrandt.

Perhaps it's something for the premium ultraportable market or some niche like that. No point in throwing a lot of GPU at something that's trying to shave the battery as much as possible. More cores at lower voltages and clock speeds keeps the MT capabilities comparable to a higher clock speed 4C without chewing through as much power.

Fantasy rumor. Strix Zen 5 APU with up to 40 CUs:


The Strix APU series would compete with up to RTX 4070 Max-Q GPU in their 40CU configuration. The RDNA3.5 GPU architecture would also be available with 32, 24 and 20 CU configurations, competing with 4060, 4050 and 3050 series of graphics from NVIDIA.

Wrong thread and a bit late...
And if they indeed employ infinity cache as well as a 256 bit RAM interface, that is not entirely impossible.
The big "if" for me is rather if AMD would be really interested in such an SKU.

Doesn't seem much faster than the 680M test he did with the 6800H. The only common game with the same settings in the two videos is Fortnite, and even though the map is different, the 780M and 680M deliver similar FPS.
Hence my bold text mentioning how there's loads of software (and the possible DDR5-5600 hardware) faults with this early preview. Not really worth basing much off of these numbers. We need post gold drivers/BIOS ones.
Ryzen chips in laptops and affordable don't fit together in one sentence anymore since Rembrandt/Zen 3+.
Seem the common denominator is DDR5 to me, but I may be wrong.
Videocardz also mentioned some variant of Asus ROG ALLY has a weaker APU, 6C12T + 4CU. Link
I wonder who would want to buy that for a gaming handheld. It will be weaker than Steam Deck.
I think it's a reporting error. The s/w also reports the 8C/16T APU having 6 CU. Maybe they are reporting WGP instead of CU?
Yep. It's pretty obvious 6 core Phoenix/Ryzen Z1 are based around R5 7640U/HS, which have 8CUs not 4 (2 more than 6-core Rembrandt/Rembrandt-R)

Wrong threat indeed but there is a component that is valid to this thread, there may be a Phoenix refresh or successor coming Q1 next year, and surprisingly it's not called Phoenix-R, it's called Hawk Point, implying bigger changes than just clock refinement. Obviously still based on Zen4 and standard RDNA3.

Edit: Later in the slides/leaks he posts, they claim RDNA3+ for Hawk Point. So it's further clock tuned N4 Phoenix + swapped out RDNA3 for RDNA3 WGPs/graphics subsystem? Huh...

Geekbench shows only 2 compute units, in this case It's most likely WGPs. That would mean only 4CU and not 8, which R5 7640HS has.


edit: changed the wording to make more sense.

We got burned with basing data on what GB says before. It does not have a authoritative hardware detection system, particularly on yet-to-be-released hardware. And it's just one data point anyway.

But we'll see, highly doubt that's the CU count tho.

they should but memory makers are allegedly cutting back on production due to over supply. it's why ddr5 prices have been tanking heavily since december. contrary to the bs some post I don't expect them to rise much at all once the effects of the stop production happen, and I don't really foresee a total cut in production due to the nature of dcs and hyperscalers needing memory out of the blue. the current ai gobbleygook nonsense will ensure there's a buyer.

this cheapness and cost slumping can be seen in SSDs, too on the consumer level. the cost slump was rumored to come onto the horizon, now, more than a year and a half ago from what i remember. we're setting ourselves up for a very cheap pc upgrade experience over the next few years.

AMD gets official about Phoenix for handhelds:



Too bad they reduced the GPU so much on the basic one. Hope eventual 6-core DIY chips get bigger GPU than that.

This doesn't seem "custom" like the Deck SOC.
Wish they had made something more customized for this segment.
IMO 8 Core is too much. Remove 2 cores to make the chip smaller and cheaper and add those customization to the memory channel to make the GPU faster.

At least will it come with some Xilinx IP?
