This thing will be worse than samsung mobiles...
You get the s24 today tomorrow will have the s25 lol. Better grab a steam deck

1 thing about the amd mobile 300 is it's 16 core gpu starving for memory bandwidth. if they fix that with high frequency lpddr or even on package memory module it would unleased the potential of their rdna 3.5 core, entice people to replace z1.

If this follows in the footsteps of the Ryzen Z1 Extreme, it'll be essentially the same thing as the Ryzen 370. But it'd be cool if it were a dedicated chip. The full GPU but fewer CPU cores would lower cost without impacting most games. More memory channels and a bigger GPU would greatly expand the capabilities of handhelds.

I hope Strix Halo and the rumored Intel equivalent do happen and are successful because I could easily see a lower end version of those being fantastic for handhelds. Both companies have been too stingy attaching high end graphics only to high end SKUs. I've been hoping this will change with tiled packaging, but we're probably at least a year from seeing what that really will look like.

Strix Halo requires a massive amount of power. It's not for handheld devices.

The differences between Z1 extreme and R7 7840U are minimal.
It's power optimized with a disabled NPU, but retains the same 8 core CPU and 12CU GPU.

Where as R9 HX 370 is a 4+8c core, 16CU GPU and 50 TOPS NPU.
You have to remember this is an R9 product, where as Z1 extreme was based off of R7.
So any number of cut down configurations would be possible from an HX 370.
Wishful thinking: 4+4c CPU, 16CU GPU, disabled NPU.

The only thing they could really do is switch to GDDR memory as it’s more than double bandwidth or go to a 256 bit bus. Where did you come up with the on-package memory idea? From Lunar Lake? On- package memory would only affect latency and wouldn’t improve bandwidth at all.

There have been consumer products with triple-channel memory, so 192 bit. That might rule out expandable LPCAMM memory though, which I think is 128 bit.

 

[Amdlova]

We need 192-bits... some CPU has memory starvation, But they say the memory controller eat too much space on die and take some power with it.
For desktop maybe We will see in future, for portable devices I don't think so.

You do realize AMD is releasing an APU with a 256 bit bus early next year, right? It also has up to 40CU of GPU.

I aggrege with you on larger bus. The idea for on package memory comes from Apple as m3 has 400GB/s on larger chip without sacrifice efficiency too much. Intel also said they reduced power requirements by the PHY by 40% on Lunar Lake. So, the way to go 256-bit bus on mobile is to go on package. On the other hand, GDDR may blow the roof on power consumption, so I don't see they go that route.

They kept saying Z1 Extreme elas rated até 8TFlops but in the end It didnt even reach 2TFlops? ALL the benchmarks I see Its performance is Just like the steam deck

Yes, but what kind of device will use it? Low powered device? Or big all in one machines?
40cu at 5w it's not same 35w 40w power target.
Amd will bring this cpu on devices 1000-2000 price range. Way pricier than a steamdeck or other thing they call portable device.

They won’t go above a 128 bit bus on a low power chip. To most, the peak performance wouldn’t justify the price they have to charge. So…poor sales.
