TL;DR
- Qualcomm is dealing with controversy about its benchmarking claims for the brand new Snapdragon X sequence of processors.
- One article claims that Qualcomm is “dishonest” by primarily fudging the outcomes to make it look like the chips are extra highly effective than they’ll truly be for customers.
- Qualcomm hasn’t been solely clear with its testing strategies, leaving few definitive solutions on what’s correct and what’s not.
Yesterday, Qualcomm formally unveiled the brand new Snapdragon X Plus chipset. Designed for Home windows on Arm laptops, the Snapdragon X Plus (and its extra highly effective sibling, the Snapdragon X Elite) is designed to carry to Home windows customers what macOS customers have loved for the reason that authentic launch of Apple’s M-series chips: highly effective, fan-less laptops with crazy-long battery life.
If you’re simply catching up on this, I extremely advocate watching the video embedded above. I give a whole lot of context to the Snapdragon X sequence and the way it would possibly change the panorama for Home windows laptops.
Sadly, not everyone seems to be as enthusiastic about these new Snapdragon X chips as Qualcomm. Charlie Demerjian at SemiAccurate just lately penned an extended opinion piece that claims Qualcomm is “dishonest” with regards to the promoted benchmarks of the X Elite and X Plus. This has began to unfold on social media and sparked a broader dialog about Qualcomm, Home windows on Arm, and the integrity of those chips.
Android Authority has attended a number of Qualcomm occasions that featured hands-on entry to Snapdragon X machines, so we thought we’d bounce into the dialog. Right here, I wish to focus on what’s occurring and what we will count on to see when retail machines with the Snapdragon X chips grow to be accessible.
Qualcomm benchmarking controversy: Some background

Most individuals studying this are acquainted with benchmarking, which includes placing {hardware} by way of an goal sequence of assessments to find out the way it compares in varied metrics to different {hardware}. If you recognize about benchmarking, you recognize that it may also be manipulated to both improve or lower the rating. For instance, operating a smartphone benchmark whereas the telephone is on a scorching desk in direct daylight will possible offer you a poor consequence in comparison with operating that very same benchmark in a walk-in fridge.
In different phrases, simply having a benchmark quantity isn’t the entire story, particularly if the individual conducting the benchmark overlooked essential particulars about the way it was obtained.
Throughout all of the Snapdragon X occasions Android Authority has attended since October 2023, Qualcomm has had loads of benchmarks to point out us. As one would count on, all of them present the Snapdragon X Elite and X Plus operating circles round competitor chipsets, together with Apple’s M3 and the newest Core Extremely chips from Intel. In all circumstances, Qualcomm claims the X sequence processors are extra highly effective, extra battery environment friendly, and higher at conducting AI-based duties. Within the case of Apple, specifically, that is fairly unbelievable when you think about Apple has already launched three generations of retail-ready Arm chips, and Qualcomm hasn’t launched any of the X sequence to retail but.
Qualcomm has been offering a whole lot of benchmarks for the X sequence, however not a whole lot of solutions.
The issue, although, is that Qualcomm has repeatedly dodged questions on the way it obtained these benchmarks. At an occasion I attended earlier than the launch of the Snapdragon X Plus, Qualcomm confirmed how far more highly effective the chip is than the Apple M3 silicon. I raised my hand and requested the presenter what the chip thermal design energy (TDP) was for each machines used for this benchmark for the reason that data wasn’t on the slide. The presenter couldn’t reply and stated they might get again to me (which they didn’t).
To my data, the chip TDP of the Snapdragon X Elite/Plus benchmarks has by no means been disclosed to anybody (do not forget that gadget TDP and chip TDP are two various things). It is a enormous drawback as a result of a major TDP disparity would dramatically alter the benchmark’s pedigree. In different phrases, if the Apple M3 laptop computer is operating at its commonplace 20W TDP however the Snapdragon X processor is operating at 80W, the benchmarks are now not comparable.
Whenever you mix this with the truth that Qualcomm hasn’t allowed any totally unbiased testing of the X sequence, you might have a whole lot of skepticism about its claims. Even when we benchmarked the Snapdragon X Elite, it was a really hands-off affair. We may solely watch Qualcomm’s chosen benchmarks occur and couldn’t set up different apps or test particulars in regards to the benchmarking gadget.
Lengthy story brief, Qualcomm has a really “belief us, bro” angle concerning its claims for the Snapdragon X sequence.
New claims of ‘dishonest’
Within the beforehand talked about SemiAccurate article, Charlie Demerjian claims to have spoken to nameless sources with direct intelligence on inner Qualcomm and companion OEM companies. Amongst many issues claimed within the article, listed below are some notable quotes:
- “SemiAccurate is 100% assured in saying that a number of the numbers Qualcomm was displaying off [to press] cannot be reproduced with the settings they declare.”
- “After OEMs obtained preliminary samples and made one thing near the ultimate designs, SemiAccurate obtained experiences of poor efficiency. By poor we imply far sub-50% of the numbers Qualcomm was telling them within the technical docs and displays.”
- “Later, with extra Snapdragon X Elite samples within the wild and plenty of extra revisions of [Windows on Arm], we obtained related experiences from OEMs and one other Tier 1. Each reported numbers that had been nowhere near what Qualcomm promised. How not shut? Above 50% this time however one used the time period “Celeron” to explain efficiency.”
Basically, Demerjian claims that Qualcomm is utilizing souped-up benchmarks to promote the Snapdragon X sequence not solely to journalists but additionally to the businesses that may make the laptops wherein these chips will truly seem.
Sadly, Demerjian has no onerous proof to point out for these claims. The explanation for that is that SemiAccurate “facilitated some questions between OEMs and Qualcomm engineers, which can level to a supply if we aren’t cautious.” Demerjian provides, “anonymity of our sources will all the time come first.” That’s all properly and good, however SemiAccurate is principally doing the very same factor it’s calling out Qualcomm for doing: “belief us, bro.”
Our take and Qualcomm’s statements
For this story, we reached out to Qualcomm. When requested in regards to the SemiAccurate article, Qualcomm had this to say:
We stand behind our efficiency claims and are excited for customers to get their fingers on Snapdragon X Elite and X Plus gadgets quickly.
When requested about its testing methodology, it stated:
Our benchmarks are measured in AC mode (wall charger linked), and are in Balanced mode (default on retail gadgets).
Notably, once we requested in regards to the chip TDP, it pointed us to a set of press supplies that don’t comprise this data. This seems to be the one factor the corporate gained’t inform anybody for no matter cause. With this lack of official data, we will solely assume the chip TDP should be excessive — a minimum of increased than Apple’s 20W. If it was 20W or decrease, in spite of everything, Qualcomm would possible brazenly inform anybody who desires that data.
Though we will’t reply the TDP query definitively in the mean time, we may give you a sneak peek at what to anticipate from Qualcomm’s chips on this space. Due to frequent Android Authority collaborator Kamila Wojciechowska, we’ve some leaked benchmarks of varied Snapdragon X machines, which you’ll be able to examine on the hyperlink. The entire thing is actually fascinating, however the gist is that the top-of-the-line Snapdragon X Elite machine has a reasonably excessive TDP because it pushes clocks increased. The opposite Elite and Plus fashions are reported to be nearer to Apple’s M3 Professional and M2, although maybe additionally nonetheless a bit increased in energy draw.
Getting again to our Qualcomm questions, we additionally requested the corporate once we may check out retail-ready laptops with Snapdragon X processors, but it surely stated it couldn’t share details about its OEM companions’ plans. It then stated, “merchandise powered by Snapdragon X Elite and our model new Snapdragon X Plus shall be introduced in mid-2024,” which is data we’ve already had.
Personally, I’m very excited in regards to the Snapdragon X sequence. Even when Qualcomm’s benchmarking claims grow to be fudged — and even outright lies — the potential of utilizing a robust Home windows laptop computer that sips on its battery is simply too attractive for me to reject outright. Even when a MacBook outperforms it in all metrics, if I can use a Snapdragon X laptop computer to jot down an article, edit a video, and play Baldur’s Gate 3 on an airplane trip whereas on battery the entire time, I’ll purchase one immediately. Numbers on a web page don’t matter to me as a lot as real-world expertise.
We’ll discover out the entire reality in just some weeks, as we count on Microsoft to unveil a Floor laptop computer operating a Snapdragon X chip in Might for a June rollout. As soon as that laptop computer is on the market, Qualcomm’s promoted early benchmarks will stand the hardest scrutiny. If the benchmarks match up, then Charlie Demerjian and others might want to eat their hats. If the benchmarks are missing, properly…Qualcomm could have a mountain of unfavorable press to cope with, placing the longer term success of the Snapdragon X sequence (and, consequently, Home windows on Arm) into critical jeopardy.
