My source just updated me with XE G2 roadmap which are supposedly launching in H1 2026. There are two SoCs planned:
1. SoC codenamed Glymur:
- Higher tier than Hamoa
- 18 cores CPU (6L+6L+6M), cluster of six
- 192-bit LPDDR5x (don't know final speed yet)
- Full DX12U features including hardware RT
2. SoC codenamed Mahua
- Hamoa successor
- 12 cores CPU (6L+6M), cluster of six
- 128-bit LPDDR5x (don't know final speed yet)
- Full DX12U features including hardware RT
That's all I know atm, at least we have an idea what Qualcomm are planning in 2026. Again, treat this as rumor until real thing happens.
My analysis of the leak
First of all, I'd like to thank Tigerick for bringing this leak to us. After taking the obligatory grain of salt, let us dive in;
1. There are 2 SoCs: Mahua and Glymur
Clearly, they are successors of Purwa and Hamoa, respectively. Looking at the memory buses (128b and 192b), it seems like there will be more differentiation between the small die and big die. This is in contrast to Purwa and Hamoa, both of which use the same 128b memory bus as far as I know (although Purwa maxes out at 7500 MT/s, while Hamoa can go upto 8448 MT/s).
2. The CPU is using larger clusters and real E-cores
Each CPU cluster has 6 cores, which is an upgrade from the 4 core clusters in Hamoa/Purwa. This is not surprising, especially after seeing what Apple has been doing with M3 Pro (6P+6E) and M3 Max (6P+6P+4E).
The other notable thing is that it seems these SoCs use "real E-cores". Qualcomm doesn't seem to use the P/E nomenclature for their big/small cores, but instead this L/M thing. I suppose L stands Large, and M stands for Medium. As a reminder, Snapdragon 8 Gen 4 has 2* Phoenix-L and 6* Phoenix-M. So these cores in Mahua/Glymur should be the next generation Pegasus-L and Pegasus-M.
3. Memory bus size has been upgraded to 192b
Glymur has a 192b memory bus, a 50% increase from that of Hamoa's 128b. Now it is LPDDR5X, not LPDDR6 as I was hoping for. It absolutely makes sense though, because using LPDDR6 in a 2026H1 laptop would be difficult. Supply would be limited, it would be very expensive and the timing would be tight (laptop chips have to be sampling to OEMs 12 months before releasing).
The fastest LPDDR5X in the market is Samsung's LPDDR5X-10667, and mating that to Glymur's 192b memory bus would yield an incredible 256 GB/s of memory bandwidth, almost twice that of Snapdragon X Elite (135 GB/s), and nipping at the heels of Strix Halo (273 GB/s)!
This large amount of bandwidth is a good sign that Qualcomm is seemingly investing in a beefy laptop class GPU, instead of overclocking a smartphone GPU as they did in X Elite.
A word on capacities; considering the 128b/192b buses of Mahua/Glymur, we can guess that laptops with it will start with 16 GB / 24 GB of RAM. By using the highest density LPDDR5X modules, they could support upto 128 GB / 192 GB of RAM.
4. Adreno 800 series based GPU architecture
Full DirectX12 Ultimate feature set and Hardware accelerated Ray tracing sounds good. Considering the circumstances, the GPU is quite obviously based on the Adreno 800 series architecture (Hamoa/Purwa's GPU is based on the Adreno 700 series architecture).
Architectural improvements of Adreno 800 seem to be massive (including greatly improved FP32 performance, which would help in PC games). Hopefully, this would mean more games run without a hitch on Snapdragon X2 laptops.
5. The 2026H1 release date
We can guess it would be announced at the 2025 Snapdragon Summit, and then be released in 2026H1, which is similar to what happened with X Elite (announcement in 2023 Snapdragon Summit, and release in 2024 June).
I do hope that 2026H1 means sometime around CES (January), instead of Computex (June). A computex release sounds very late (full 2 years after X Elite's release). Intel's Panther Lake is rumoured to land in late 2025/early 2026, so I hope Snapdragon X2 comes in time to challenge it!
