JEDEC® Releases New LPDDR6 Standard to Enhance Mobile and AI Memory Performance | JEDEC

Yep, about time: Right before year-end launching of important SoC.



So far, we know 8 Elite G2 and X Elite G2 are going to support LPDDR6. Both SoC are using same Oryon v3 cores, GB6 ST should surpass 4000+. X Elite G2 would be in range of upcoming Apple's M5 Pro.



Still not sure Dimensity 9500 with X935 cores would support LPDDR6 or not, we shall see...

No signs of iPhone SoC would employ LPDDR6. But man, I would bet M5 series are going full throttle support of 96-bit, 192-bit and 384-bit LPDDR6.

NV's GB10 might as well, we shall see. In case of supporting LPDDR6, GB10 would be in range of M5 Max, not Pro level.

From previous generation GB6 scores below 3000 average... (oryon v1)
The expectation that it suddenly jumps higher than 4000 score is a dream story.

Qualcomm Technologies, Inc. is a global leader in AI edge innovation and is proud to be one of the first in the industry to implement LPDDR6

One of the first, interesting terms. Cause we know Qualcomm will announce both SoC in Qualcomm Summit in Sept 23. They should claim the first if no other vendors are announcing LPDDR6 support before Sept 23. Hmm, from now on until Sept 23, there are following events:

• NV GB10 launching this month
• Mediatek Dimensity 9500 may drop earlier in Sept

Two vendors which could potentially launch their SoC supporting LPDDR6. We shall hear more in the coming days...

I don't know. I wouldn't bet against Gerard Williams.

Qualcomms aim will be to beat M4 Max and for that they need to aim for >4000.

Probably only possible way outside of some serious miracle is a crazy good implementation of SME.

Cadence announced yesterday that they taped out a combined LPDDR5/LPDDR6 controller.

Given how different the standards are, that's a weird product.

Probably means that there's a lot of untapped LPDDR5 supply and it may not dry up for a couple years at least. Also, shifting complete production over to LPDDR6 isn't something they want to do with all of their fabs for cost reasons so probably gonna keep pumping out LPDDR5 for quite some time.

For OEMs who want to serve a wide range of products with a single SoC maybe that's not too crazy? Either because you want to operate at different price points (LPDDR6 is going to cost a lot more than LPDDR5/X for the first couple years) or you plan for a single product to live long enough that the supply of LPDDR5 might dry up before you replace it.

I'd really be curious to know how its size compares to the size of their LPDDR5 only and LPDDR6 only controllers in the same process. Maybe there is no area savings per se but if there are significant savings in shoreline that might be enough to justify this misfit toy.

1) GB10 is LPDDR5X-8533 not LPDDR6
2) I doubt that any SOC launching this year will have LPDDR6 because none of the memory manufacturers have announced LPDDR6 high volume production and the JEDEC announcement doesn't actually say that 8 Elite G2 or X Elite G2 will have LPDDR6... Perhaps it uses LPDDR5X/LPDDR6 but launches with LPDDR5X to start with...
