9 places, do you think the upgrade to iPhone 15 Pro is worth it?

Many people in terms of hardware of the iPhone 15 Pro series released by Apple said that the upgrade was not as large as when the iPhone 14 Pro was launched. Is there no value in upgrading? Is the iPhone 15 Pro just a light upgrade from the 14 Pro?

#1: No obvious performance upgrade?

Indeed, the A17 Pro, which uses a 3-nanometer process, has improved CPU and GPU performance by 10% to 20% compared to the previous generation, but it is only based on the core frequency. The improvement, in terms of performance alone, is not significant. Therefore, in terms of core benchmark scores, the A17 Pro is not a model worth buying for benchmark users.

Tests on the Internet have found that after overheating and downclocking, the performance of the A17 Pro has exactly the same problem as the A16 Bionic when the frequency is the same. The author believes that there is still a problem after downclocking. The full performance of the previous generation core is actually an improvement. Will the A16 chip not be down-clocked?

Of course, as the frequency of A17 Pro increases, the heat will naturally be higher, and it will be more prone to frequency reduction problems. This problem may have different ideas for different users, but I think this time Apple uses 3 nanometer The room for improvement brought by the manufacturing process does not focus on performance scores.

2:3 The real improvements brought about by nanotechnology

The improvement of nanotechnology allows manufacturers to put more transistors in the same space. This means that manufacturers can add more different designs while maintaining performance. What Apple has chosen is to add more different hardware to the chip, including RT ray tracing cores and improved AI cores. Working together with the GPU, it can Have better sampling performance.

First of all, the core of RT is to allow iPhone to run ray tracing of games like PS5 and PC. This is an extremely resource-intensive action. In the past, it could only be simulated by software, but as everyone knows, software simulation The efficiency is very low, so after adding the RT core, the performance of light and shadow tracing can be improved by 4 times.

Of course, AMAM upgrade is also very important. Since the iPhone does not have too much RAAM, the system design even 6GB is enough. However, if you want to face 3A For game masterpieces and professional software such as Final Cut Pro, RAM capacity is the key. Therefore, the capacity of RAAM is increased to 8GB, which is the same as the iPad M series, and the performance is further smoother.

MetalFX Upscaling is an improvement of AI and GPU, which allows the device to automatically lower the special effects in some places that the user will not notice much during calculation, freeing up more resources to deal with the objects that the user is looking at. , the effect is somewhat like Nvidia's DLSS 2.0 experience. Therefore, after using the new hardware and the game developer's optimized settings to run games on the iPhone's less than 7-inch display, the A17 Pro can run PC-level 3A game masterpieces and Not impossible. This is also the conclusion that Apple came to after balancing performance and new hardware. It is not that the iPhone 15 Pro has not improved as the outside world said, but it requires a multi-angle understanding of why Apple has such confidence in the A17 Pro.

3: Camera

Although the main camera of the iPhone 15 Pro has not been upgraded in terms of hardware, it also uses a 1/1.28-inch CMOS sensor. The A17 Pro's ISP can allow the system to better utilize the performance of the same CMOS, such as reducing noise and quickly adjusting various settings during shooting. After adjustment by Apple, in addition to 48 million pixels, the camera can also be set to 24 million pixels. 10,000 to 12 million pixels to balance resolution and performance under ambient light.

48 million pixels can capture more details under sufficient light, allowing users to zoom in without blurring the photo, while 12 million pixels sacrifice resolution. , improve photosensitivity, reduce noise, and improve the effect of photos. However, when enlarging photos on large screens such as 4K TVs, graininess will easily appear. The new 24 million pixels are a balanced choice between resolution and light sensitivity. It is the most commonly used resolution value for single-lens reflex cameras (single-lens cameras).

#4: Titanium alloy body

#Apple finally gave up on the stainless steel body design. That’s right, Apple’s Stainless steel material can improve the texture when held in hand and has higher hardness than aluminum. However, the weight has increased significantly. The body of the 11 Pro Max has increased from 226g to 240g of the iPhone 14 Pro. It will cause discomfort to the hands after long-term use. The feeling will increase, and the weight-to-strength ratio of titanium is higher than that of stainless steel, which means that the body can be stronger and lighter at the same time. The weight of iPhone 15 Pro Max has dropped to 221g, which is lighter than iPhone 11 Pro Max. Of course, the cost is Generally higher than stainless steel.

5: Pro Max’s unique 5x optical focal length

#iPhone 15 Pro Max’s unique 5x optical focal length telephoto lens can be used like the iPhone Capture farther images. At the same time, Apple has also added a mobile image anti-shake function to this lens. I believe it is the most practical update at present. You must know that telephoto lenses are the most affected by hand shake among all focal lengths.

Generally speaking, the farther the focal length of a telephoto lens, the worse the light sensitivity will be due to hardware limitations. However, Apple’s 5x lens has the same aperture as the 14 Pro Max, while the 15 Pro Max The CMOS is larger, with a pixel size of 1.12, which is larger than the 1.0 micron of the 14 Pro Max, so the imaging of the 15 Pro Max will be better.

6: USB C with 3.0 speed

Apple finally added USB 3.0 speed to the iPhone, why not just use TB 4? Directly upgrade to the highest specification, how to continue making toothpaste? The data transfer speed has been increased by 20 times, which allows users to connect a USB 3.0 SSD to take photos and videos, and then store them directly in the external SSD.

Of course, don’t ask why you need to use an iPhone with an external SSD to shoot, and you don’t need to carry professional photography equipment... Well, shooting with an iPhone is more convenient. However, the author is quite happy to see the speed increase brought by USB 3.0 alone.

7: ProRes format finally supports 4K 60fps

In the past, ProRes format has always supported up to 4K 30fps photography. For those who want to shoot with iPhone, you can The video produced is only 30 fps, which is a big limitation. Some close-up slow-motion effects cannot be shot using ProRes.

8: Finally Wi-Fi 6E

#Just as the world is preparing to enter the Wi-Fi 7 era, Apple finally provides the latest generation iPhone With Wi-Fi 6E, although the connection speed is not significantly improved, the addition of the 6GHz frequency band reduces the interference problem of 5GHz starting to saturate, and the connection is more stable, although the penetration will definitely be affected.

9: The second-generation ultra-wideband chip

Ultra-wideband chip has actually been used in AirTag. The first one used by iPhone is iPhone 11 and The updated version, and now the iPhone 15 Pro series, uses the second-generation chip. The improvement compared to the previous generation is that the precise positioning distance is increased by 3 times, allowing you to find the target you want at a farther distance. For example, an object, or a friend's iPhone.
