As the dark of the night rolls into China this evening, Qualcomm is hosting a mobile-focused product launch event they’re calling “Snapdragon Night”. Headlining the event is the announcement of the company’s new flagship SoC, the Snapdragon 8+ Gen 1. A mid-generation update to their flagship smartphone SoC, the Snapdragon 8 Gen 1, the 8+ Gen 1 follows Qualcomm’s annual tradition of releasing a refresh product to boost performance and to give partners something new to work with for the second half of the year. And for this year in particular, we’re looking at a very notable change in chips from Qualcomm.

Unlike previous generations where Qualcomm merely launched a faster speed bin of their existing silicon, for 2022 we have something more substantial to talk about. Qualcomm has switched up foundries entirely – moving from Samsung to TSMC – and as a result is rolling out a new die. Thanks to this, the Snapdragon 8+ Gen 1 Qualcomm is reaping something of a one-off manufacturing gain, allowing them to both dial up CPU and GPU performance while simultaneously cutting power consumption.

Quickly diving into the specifications, the new Snapdragon 8+ Gen 1 is essentially the original Snapdragon 8 Gen 1 ported over from Samsung’s 4nm line over to one of TSMC’s 4nm lines. Under more normal circumstances, this kind of a shift would likely be unremarkable – or at most, an amusing exercise in looking for edge cases – however for Qualcomm’s flagship SoC, the matter is more significant.

While official sources and statements on the quality of Samsung’s 4nm process are few and far between, unofficially, it’s become clear that Samsung’s 4nm process hasn’t lived up to expectations. This has caused a cascading impact on the chips made on the process node, leading to the original Snapdragon 8 Gen 1 developing an affinity for power consumption, and Samsung’s own Exynos 2200 not faring any better. Conversely, by all accounts TSMC’s N4 process is looking great, with the optically shrunk node building off of TSMC’s already successful and very performant 5nm technologies.

As a result of this performance gap between Samsung and TSMC’s 4nm nodes, Qualcomm is taking the unusual step of (essentially) porting their high-end SoC over to TSMC’s fab. Which, although not strictly necessary – Qualcomm carries a lot of momentum and the 8 Gen 1 has been selling well – is certainly a prudent move for the company. Qualcomm is facing especially stiff competition this generation from MediaTek, whose flagship-level Dimensity 9000 SoC was the lead product for TSMC’s 4nm node. And that leaves MediaTek with a distinct advantage against the original 8 Gen 1, one that Qualcomm would be very happy to nullify.

Ultimately, the switch in fabs is giving Qualcomm a chance to improve upon the original 8 Gen 1 from both ends of the spectrum, resulting in the Snapdragon 8+ Gen 1. On the performance front, TSMC’s node affords them an easy opportunity to increase CPU and GPU clockspeeds for more performance. The prime Cortex-X2 core is now clocked 7% higher, at 3.2GHz, and meanwhile the A710 and A510 clusters have seen their clockspeeds dialed up even more significantly, by around 12% each. Now even the slowest A510 cores can run at 2GHz. GPU clockspeeds have also been similarly increased, and while Qualcomm does not disclose specific clockspeeds there, they have confirmed that the 8+ Gen 1’s Adreno GPU block is clocked 10% higher than the original 8 Gen 1.

But, if anything, the bulk of Qualcomm’s gains from the switch in manufacturing nodes are being invested in cutting power consumption. Something of a sore point with the 8 Gen 1, TSMC’s better 4nm process means that Qualcomm is seeing much lower power consumption across their SoC at iso-frequency.

Officially, Qualcomm is claiming a 30% improvement in both GPU and CPU power efficiency. Though as mentioned before, this is at iso-frequency and doesn’t take into account the higher peak clockspeeds of the 8+ Gen 1. Consequently, the real-world power savings aren’t going to be quite as great on a peak-to-peak basis, but according to Qualcomm the power savings are still significant. Overall, the company is touting a 15% reduction in SoC power usage under “practical usage patterns” versus the original 8 Gen 1, which in turn should lead to improved battery lifetimes in handsets that adopt the new SoC.

Past that, the official specifications for the 8+ Gen 1 do not reflect any material changes to the SoC’s configuration versus the original chip. So we’re still looking at the same integrated X65 5G modem, the same Spectra ISP, and the same video encode/decode blocks (sorry, gang, still no AV1 support!). So, despite assembling a new die for their mid-generation refresh product this year, there aren’t any new features to speak of with the 8+ Gen 1.

As for SoC performance, officially Qualcomm is claiming 10% improved GPU and CPU performance, owing to those aforementioned clockspeed increases. While we weren’t able to attend a benchmarking session that Qualcomm held last week, the Performance Mode figures being released by the company are roughly in-line with these claims. Qualcomm’s Geekbench 5 results are several percent higher than what we benchmarked back in December at the 8 Gen 1 launch event, though it’s notable that they didn’t achieve meaningfully higher scores in PCMark. GPU performance figures are similarly mixed, with some of Qualcomm’s official results coming very close to our original 8 Gen 1 results, but I’m reluctant to read too much into them given how much if a difference peak versus sustained testing makes in GPU results. As always, the final word will need to come down to independent, third-party testing, though at face value nothing Qualcomm claims is unreasonable given the clockspeed improvements and the thermal headroom gained from the switch to TSMC.

Finally, as for consumers, they’ll be able to get their first look at Snapdragon 8+ Gen 1 devices in Q3 of this year. According to Qualcomm, many of the usual suspects have signed on to release phones based on the new SoC, including Asus, Motorola, OnePlus, Honor, and Xiaomi.

    It's likely they're not going to do much better at the 3nm node:

    It will be pretty rough if TSMC beats them as usual, but with Samsung having moved to GAAFETs while TSMC holds off on that until 2nm.

    Some analyses I saw were optimistic about Samsung since they were moving to GAAFET first.
  • brucethemoose - Sunday, May 22, 2022 - link

    They were similarly optimistic about Samsung's aggressive EUV plans.

    Early GAAFET could be a blessing or a curse.

    They’ve been struggling since 14nm, at least.

    Think back a few years when Apple had 50% of its iPhone chips made on Samsungs 14nm, and 50% made on TSMC’s 16nm. The TSMC chips were 20% more efficient and almost 20% faster. Apple had to work to equalize the performance, but the efficiency differences remained. After everything in a phone are accounted for, such as the screen and the separate modem, the overall difference between the phones came down to about 5%.

    But Samsung’s process has never been world beating.

    The important thing is that everyone has known about it, and that's why Samsung has been around 30% cheaper than TSMC on similar (should've been) nodes.

    The QSD 855 chipset from years past was pretty great. Since then all the performance gains came with the increase of energy and heat. In fact, that same YouTube quoted above was able to customise it (Xiaomi Mi 9) with a +45% GPU gain and +35% CPU gain. That allowed it to narrowly surpass the QC 8g1 in performance, and it did it at slightly less power. Basically a tie. So from early 2019 to late 2021, Qualcomm hasn't made an overall improvement.

    I think Samsung's lithography is to blame. Their 5nm nodes are more-like 8nm nodes, while their midrange 8nm node is more like 12nm node. That's still ahead of Intel, and far ahead of GlobalFoundaries and SMIC. However, TSMC is just in a different league with their 4nm and 6nm nodes.

    Why are you spreading this misinfo everywhere? 865 is much more efficient than 855. Go watch geekerwans latest video. Someone even linked it here.
  • Kangal - Monday, May 23, 2022 - link

    Based on a lot of reports from people who have the OnePlus 8 and the Samsung S20 line of phones. It's basically because the Cortex-A77 is less efficient than the Cortex-A76 in lower voltages, but the A77 can increase it's performance further than the A76 based on ARM's projections and designs. The other factor is the thirsty 5G modem in the 865, whereas this was an external option in 855 devices.

    If you run only synthetic benchmarks, the QSD 865 will look more efficient. But when you look at the complete package, the QSD 855 stacks up competitively. The QSD 865+ was merely an overclocked QSD 865. However, the QSD 870 actually uses a new process-node in its construct and it is using a new software stack/updated drivers (probably the 5G as well). I haven't heard of QSD 870 phones throttling or having heat issues, and testing shows it has actually lower drain than the 855 and higher sustained performance than 865+. So that's a decent chipset, but nothing worth celebrating when looking at the Apple A13-Bionic, let alone the A14 and A15 variants.

    ...with all of this said, the chipset is not all there is to a phone/device; I'd much prefer the Samsung A52-s over the Moto Edge X30.

    Just go watch the video. Look carefully at the efficiency curves of 855 and 865.
  • iphonebestgamephone - Monday, May 23, 2022 - link

    Oh and look carefully at the 870s curve too.
