TSMC expected to charge $45,000 for silicon wafers used to produce 1.4nm chips by 2028
Next year we should start to see flagship smartphones move from using application processors (AP) made with the 3nm process node to those made at 2nm. This will result in the use of smaller Gate-All-Around (GAA) transistors allowing more of them to fit inside an AP. Using vertical nanosheets stacked horizontally, GAA transistors surround the channel on all four sides reducing current leakage, improving the drive current, and enhancing the performance and energy efficiency of these SoCs. Silicon wafers for 2nm production cost $30,000 which is a high price to pay for the underlying substrate on which chips are built in layers. Getting manufacturers to pay $30,000 for each wafer is hard enough; TSMC started accepting orders for 2nm chips on April 1st. But the price of silicon wafers is about to get even more prohibitive. According to China Times , when TSMC moves to its 1.4nm Angstrom process node, silicon wafer prices will rise 50% to a whopping $45,000 per wafer.
We probably won't see TSMC churning out 1.4nm components until 2028 at the earliest and at $45K, only TSMC's most well-heeled customers will be able to afford it. Luckily for the world's largest foundry, some of its largest customers might not think twice about shelling out such a sum for a silicon wafer. The firms include Apple, Nvidia, AMD, and Broadcom. It is interesting to see that Apple typically values the performance of the iPhone above other aspects of the device. For example, even though Apple is well behind Google and Samsung in AI, the company made sure it was among the first to pay the higher wafer prices when TSMC started producing 3nm chips. TSMC's 2nm timeline is probably behind Apple's decision to use the foundry's 3rd generation 3nm process node (N3P) on this year's iPhone 17 line expected to be unveiled in September.
Apple will probably be among the first to pay $30,000 for 2nm production. The A20 and A20 Pro APs powering the iPhone 18 series could be the first 2nm chipsets found inside the iPhone. When the time comes for TSMC to schedule 1.4nm production in a few years, you can be sure that Apple will pay the $45,000 price for silicon wafers. It might do so begrudgingly, but it will pay the higher price to keep the iPhone's performance ahead of the rest of the pack. The Snapdragon 8 Elite 2 AP powering the Galaxy S26 Ultra will also be produced using TSMC's third generation 3nm chipset. The same process node will be used by MediaTek for its Dimensity 9500 AP.

Sony Xperia I VII camera score revealed: What is Sony doing?
The Sony Xperia 1 VII is here, and it's Sony's latest grasp at relevancy in a modern smartphone market that has seemingly left the Xperia lineup in the past. With modest upgrades on board, the new Xperia comes with a new higher-res ultrawide camera, but still relies on the same 48MP main camera and 12MP telephoto with variable focal length that can provides optical zoom at 3.5 and 7.1X zoom levels (85 to 170mm in 35mm film equivalent). Sony has put a new 48MP ultrawide in its latest Xperia flagship, an improvement over the 12MP one available on the older Xperia 1 VI flagship phone. However, the other two cameras are pretty much identical to their predecessor, but Sony has shaken up the image-processing algorithms in order to get closer to some of its bigger competitors, which are also using Sony's sensors. And don't get fooled by Sony's naming scheme: the Exmor T and Exmor RS sensors here are equivalent to the new LYTIA ones that are making the rounds on pretty much any high-profile flagship out there at the moment. How does this all pan out for the Sony Xperia 1 VII ? Well, with a total score of 136, the latest Xperia isn't really doing great. Broken down, this result is made of a mostly okay still photo result of 142 points, but a disappointing video score of 130 points. That's in the ballpark of the old Xperia flagship, but slightly lower in comparison, which isn't the way camera evolution is supposed to go. Now, compared to most of its direct rivals from the midst of the Big Three––Samsung, Apple, and Google––the Xperia 1 VII isn't doing particularly good. It achieves a significantly lower score than more capable cameraphones that are also significantly more affordable, like the Galaxy S25 Ultra, Pixel 9 Pro XL, and the iPhone 16 Pro Max. While this isn't great for Sony, what's actually concerning here is that the Xperia 1 VII fares slightly worse than last year's Xperia 1 VI in our tests. This is indicative that the changes in the image-processing aren't in the correct direction, which is sad to see. Let's delve deeper and take a look at some camera samples. Sony Xperia 1 VII camera spider chart The main camera delivers images with true-to-life colors and dynamics that look very realistic. Details are okay, but you can notice some oversharpening artifacts here and there. Auto exposure leaves something to be desired, as it has some issues with nailing the correct exposure level. The dynamic range is okay, but sometimes highlights tend to burn out. There are also some nasty HDR artifacts here and there. 3.7X 7.1X 3.7X 7.1X The telephoto is good, delivering good detail at both the native 3.7X and 7.1X optical zoom levels. There is minimal oversharpening and good sharpness at both zoom levels. The ultrawide camera here is a noticeable improvement over the one on the Xperia 1 VI, so at least we have palpable improvements here. The detail and corner sharpness have been improved, but some oversharpening tends to creep in now as well. The front-facing camera is just okay. It sometimes struggles to determine the correct exposure setting, leading to slightly overexposed facial features. Detail is lacking in comparison with most of the phone's direct rivals. The main camera delivers decent exposure, good dynamic range, and okay details with minimal amounts of oversharpening. Still, most rivals of the device deliver better footage with their respective main cameras. 3.7X At the shorter 3.7X zoom level, videos are perfectly usable, with decent quality. 7.1X At 7.1X, a general loss of quality and worse detail can be observed. While the ultrawide is great in photos, it's so-so in videos. Corner-sharpness leaves a lot to be desired, and the exposure errs on the side of overexposing the image. The front camera delivers lifeless videos that lack both character and detail. Definitely among the worse front-facing cameras we've tested this year. The Sony Xperia 1 VII will easily feel like more of the same to seasoned Xperia fans. It offers nothing groundbreaking in the camera department, doesn't stand out with any particularly intriguing new feature, and you could even make the case that the overall image capabilities of the camera have deteriorated in comparison with the previous model as well as the direct rivals. While the camera will do fine in most situations you may find yourself, it will rarely excite or inspire you to create more. While Sony definitely has a galactic level of know-how when it comes to camera sensors, this knowledge fails to translate well to the real-life camera performance of its flagship phones.\ The Xperia 1 VII's rivals easily beat it in the camera department, while carrying significantly lower price tags.

iPhone 18 Pro might debut Apple's boldest chip upgrade in years
Apple's next big chip leap might be closer than we think. A fresh rumor hints at some major behind-the-scenes changes for 2026's A20 chip – and if true, it could set the stage for some of Apple's most exciting devices yet. We are yet to see the iPhone 17 series and its reported dramatic redesign, but rumors and leaks about next year's iPhone 18 series are spreading like wildfire. We're hearing that the base iPhone 17 may come with the iPhone 16's chip, but the Pro models will get upgraded to a new one, albeit still built on a 3nm process. It seems the jump may be bigger with the A20 chip, the one that's supposed to power the iPhone 18 Pro and Pro Max. According to GF Securities analyst Jeff Pu, the Cupertino tech giant may launch the A20 processor with the Pro-branded iPhone 18 and the mysterious first foldable from the company. Pu says that the new chip will use the 2nm process. As I already mentioned, the A18 chip (the current one) is built on a second-gen 3nm process, known as N3E. The upcoming A19, which is likely to power the iPhone 17 Air, is said to use a third-gen, N3P, process, but still 3nm. The process the A20 may use is referred to as N2. It would be a first-gen process. Basically, what this could mean is that the A20 may be about 15% faster than the A19, and more efficient (about 30% less power used than its predecessor). The iPhone 16 Pro sports the A18 Pro chip. | Image Credit - Apple It's been months that the rumor about the iPhone 18 models sporting a 2nm has been going around. Earlier, Ming-Chi Kuo stated all iPhone 18 models would come with such a chip, only to change his opinion later – to indicate that only the iPhone 18 Pro models would come with this chip. But there's another aspect to this story worth mentioning. A physical redesign of the chip is also rumored. Yes, a reduction in chip fabrication size is always beneficial, but a new design could bring even more advantages. Pu believes Apple will use TSMC's new Wafer-Level Multi-Chip Module, or WMCM. This new packaging process reportedly puts the memory straight onto the chip wafer. This means the memory will reside closer to the CPU, GPU, and Neural Engine. Thus, memory bandwidth should increase, as well as performance. Such a design, featuring shorter transits, will also help the hardware run cooler and even provide better battery life to the device. There were previous rumors about such a design originating in the Chinese social media website Weibo. However, Pu's notes are giving credibility to this rumor now. The iPhone 18 series is still shrouded in mystery, expected in 2026. Before these phones, we have the iPhone 17 phones to look forward to, coming in the fall of this year. There may be a new design to the iPhone 17 Pro and Pro Max, and also a new model may come to replace the 'Plus' – an iPhone 17 Air . The Air is expected to be a super-thin rival to the newly-announced Galaxy S25 Edge. As for Apple's first foldable iPhone , this one is expected to be a book-style foldable, similar to the Galaxy Z Fold models. A massive leak earlier this year revealed quite a lot of what we might expect from this phone, but so far, everything is unconfirmed and speculative. Meanwhile, Samsung is about to unveil (in early July) its next-gen Galaxy Z Fold – the Galaxy Z Fold 7, which is said to sport the Snapdragon 8 Elite for Galaxy, the chip in the Galaxy S25 series. Although it's very early to know for certain anything when it comes to the iPhone 18 (and 17, if I may add), this leak paints an exciting picture nonetheless. What draws me in especially when it comes to these improvements isn't the speed, per se, as for me, flagship processors are fast already, but the improvements in battery life. For me, battery life as a key aspect of the experience with a phone is of utmost importance, and any upgrades here are always welcome.
