Qualcomm's 5GHz phone chip ran Geekbench at 4.6GHz

A 5.01GHz ceiling and a 4.60GHz benchmark trace can both be true. The gap between them is the useful part of this leak.

On 25 August, Notebookcheck published a Geekbench listing for a device identified as vivo V2606A, running Android 17 with 16GB of RAM and a chip Geekbench simply calls "QTI SM8975". That part number has been floating around Weibo for months as the top-end Snapdragon of the coming generation. The listing shows an eight-core layout — two cores topping out at 5.01GHz, three at 4.03GHz, three at 3.74GHz — which would put a phone processor past 5GHz on paper for the first time.

Then the frequency telemetry from the same run shows the chip sitting at roughly 4.59 to 4.60GHz for the duration. Not 5.01. And the scores it produced were 3,434 single-core and 9,334 multi-core.

Those are worse numbers than last year's part. Notebookcheck puts the Snapdragon 8 Elite Gen 5's average Geekbench results at 3,631 and 10,940. GSMArena, which tests devices in-house rather than pulling averages, recorded 3,643 and 10,466 on the iQOO 15 — and it thinks the V2606A is the iQOO 16, making this close to a like-for-like generational comparison that goes the wrong way. GSMArena's Sagar noted the unit is "probably a prototype, which likely led to a lower Geekbench score."

Notebookcheck and Android Authority both identify the result as coming from pre-production hardware and firmware, so neither treats it as a retail-performance verdict. The listing itself does not reveal why the processor stayed below its advertised ceiling; unfinished power management, conservative thermal limits and benchmark configuration are possibilities, not facts established by the run.

MediaTek's side of the ledger looks the same. The Dimensity 9600 Pro's recent Geekbench appearance produced 2,653 and 7,516 — also below its predecessor, and also from a pre-release device. Android Authority's Akshay Gangwar reached the obvious conclusion about both: scores from pre-production devices and firmware "should be taken with a pinch of salt."

Qualcomm supplied the strongest corroboration in its own 25 August technical post. The company says its next Oryon CPU is the first mobile CPU to reach 5GHz and pairs that clock with higher instructions-per-clock performance. That confirms the frequency target, although Qualcomm has not attached the leaked Extreme Gen 6 name to the platform.

So the 5.01GHz in the Geekbench entry is not a misread. It is the design target, and Qualcomm is willing to put its name to it before Snapdragon Summit, which runs 22 to 24 September in Hawaii.

The IPC half of that announcement matters as much as the gigahertz. Two chips at identical clocks can differ substantially in throughput depending on how much work each cycle completes, so frequency alone is not a performance ranking. Qualcomm also describes a new FlexCache design that lets different core types draw dynamically from the same cache pool. The company claims this can reduce memory traffic and stabilise frame rates, but those are vendor claims awaiting independent tests on retail phones.

Tipster Digital Chat Station claims SM8975 will ship as the Snapdragon 8 Elite Extreme Gen 6, with SM8950 taking the plain Snapdragon 8 Elite Gen 6 label — a two-tier flagship split rather than the single halo part Qualcomm has run in recent years. Android Authority's response to that name was blunt: "Qualcomm's naming convention is getting further out of hand."

Per the same Weibo leak, the Extreme runs on TSMC's 2nm process with an Adreno 850 GPU, said in earlier leaks to carry six GPU slices. Notebookcheck's read of the Geekbench backend independently confirms an Adreno 850 in the listing, which is the detail that gives the whole entry credibility. Digital Chat Station also put the Dimensity 9600 Pro on TSMC 2nm, with two Canyon cores at 4.55GHz, three Gelas-b at 4.35GHz and three Gelas at 3.10GHz, paired with an Arm Mali G2 Ultra NX MC12.

Not another Geekbench listing. Geekbench 6 runs for a couple of minutes and rewards peak boost; it is a poor proxy for a phone that has to hold clocks through a long session. The number worth waiting for is what the retail iQOO 16 does after half an hour of sustained load, and how much battery it burns getting there. A chip capable of 5GHz does not mean every phone will hold that speed once cooling and chassis design are in play.

There is one more reason to hold judgement. Xiaomi has claimed 3,945 and 15,221 in Geekbench 6.5 for its own Xring O3 — figures Notebookcheck explicitly flagged as first-party data deserving skepticism. For Qualcomm's next platform, the firm evidence is narrower than the rumour cycle suggests: a public Geekbench entry and Qualcomm's confirmation that its next Oryon CPU reaches 5GHz. The Extreme Gen 6 name, 2nm process and detailed product split remain attributed leaks.

The iQOO 16 is expected in China around late September or early October, having already cleared 3C certification. It should be the first retail device to answer the question this listing raised.
