If Purwa is a separate, 4+4 die, I would be very surprised if QCOM achieved perfect yields or didn't had a binned SKU. 6C is still a perfectly valid option for low-end. Specially when competition (Intel) sells 2P + 4E. 6P would be a literal erase on Intel offerings.
They didn't make a cut down part of the 8 Gen 2. That was a 120 mm² SoC.

Purwa should be somewhere about size.

Btw, are there no Semiccurate subscribers in this forum?

A recent news story came out that Google is going to be forcing Youtube AV1 playback on all Android phones, including the ones which don't have hardware accelerated AV1 decoding.

Those phones will have to software decode AV1 using the CPU, which would take a hit to battery life and performance of the device.

Now, a group of people are mad at Qualcomm (rightly so, arguably) due to the fact that Qualcomm is gatekeepers AV1 support for their non-flagship SoCs.

The Snapdragon 8 Gen 2, 8s Gen 3 and 8 Gen are the only chips with AV1 decode. Not even the recently released Snapdragon 7 Gen 3 has AV1 decode. Even egregious- the Snapdragon 7+ Gen 3 (which is cut of the same die as the 7s Gen 3), does not have AV1 decode, which clearly shows Qualcomm is artificially withholding support for AV1.

In contrast, Mediatek's midrange Dimensity 8000 series chips have AV1 decode, and so do all of Google's Tensor chips (which are used in the midrange Pixel A series phones). The Exynos 2100 and Exynos 2200 also had AV1 decode, whereas their Snapdragon counterparts, the 888 and 8 Gen 1 do not, in a rare W for Exynos
Sounds like Google is abusing their YouTube monopoly to give themselves an unfair advantage in the phone market... "Hey look, our midrange phone plays YouTube super smoothly!"

So our headcanon is this:

12 cores = Snapdragon X Elite
10 cores = Snapdragon X Plus
8 cores = Snapdragon X

X Elite and X Plus is from Hamoa die. X is from Purwa die

It is advantageous for them, becuase by switching to AV1 and ditching other codes, they can cut down on their server network bandwidth.

Stop asking for people who pay a lot of money for something to post it for free here. It is surely against Charlie's T&Cs and would get their subscription cancelled. We may not like that he keeps his stuff behind a paywall but that's the model he's adopted and given the fact that even a large site like Anandtech can't afford to keep top people like Andrei we can hardly argue that the free+ads model would pay his rent.

Snapdragon SoC's only just started supporting AV1 in its ASIC decoder block as of SD8 Gen3, so support for it is by no means at a critical mass in the hands of the public.

I reckon the Surface Pro 10 and Surface Laptop 6, will use the Snapdragon X Elite and Snapdragon X Plus.

Meanwhile in the future, a potential ARM version of the Surface GO and Surface Laptop GO will get the regular Snapdragon X.

Snapdragon X2 series Speculation/Concept v4


This time I have decided to not bin the memory controllers, but to bin the caches instead.

Also taken into consideration that N3P offers FinFlex.

Those with phones that lack hardware decoding have voiced battery concerns
This will affect Snapdragon users significantly, because other than the 8 Gen 2/8s Gen3/8 Gen 3, all their SoCs lack hardware accelerated AV1 decode. This means the AV1 will be decoded by the CPU using software decode, which will affect battery life of the phone.

Apple users will get worst of this as only the A17 Pro has AV1 decode. At least Qualcomm supported it from late 2022.

Apple still don’t have AV1 encode on their M3 line. Meanwhile, Qualcomm introduced it with the X Elite and Intel had AV1 encode for a while now.

X Plus based on the same Phoenix die. What is Purwa then?
Probably for some even lower end SKUs.

The total lack of ST boost is surely the most disappointing news on this, still relatively high-end SKU.

It's a drop from 4.2 to 3.4 GHz, which makes it slower in CB2024 ST than the original entry-level M1 (soon to be 4 year old).

The MT score is actually still quite decent (despite a noticeable drop from X Elite). It's still faster than the M2 Pro and about the same that a desktop Ryzen 5800X or i5 14400.

Snapdragon X Plus is announced?

This is BOMBSHELL NEWS. The biggest since last October.

Edit: Oh it's a leak

This numbering system is very interesting.

Tiers, SKUs, Variants.

What constitutes as an SKU, and what is a Variant?

Sorry if this has already been reported but some X1E84100 Geekbench scores have been posted: https://browser.geekbench.com/v6/cpu/5826402

ST 2935 / MT 15704
Not bad. Almost exactly the reference 14600K scores:

Then again the ST result is already a bit behind the M3 Pro:

It will be a much tougher fight against next gen AMD / Intel / Apple processors. The disabled turbo on X Plus chips really hurts its competitiveness IMO.

I'm sure Qualcomm has a lot of low hanging fruit to improve upon though, so it all depends on the execution of the followup cores

It's not a tough fight against AMD/Intel mobile SoCs because they're extremely far behind both Apple and Qualcomm in perf/watt.

X Elite is a hair behind M3. That's already fantastic.
