Tencent Digital (Compile: Guti) Sony's new PS4 Pro host has officially unveiled, compared with the previous PS4, PS4 Pro has been improved and upgraded in many ways, interested players need to know about.
First of all, the PS4 Pro has added 4K ultra-high-definition picture output capability, and supports HDR playback, and has upgraded internal components and configurations to make the game run more smoothly and the picture can present more details. For this reason, developers need to develop two modes of game, including PS4 basic mode and "Pro mode", while the latter consumes more resources than the basic mode, but the effect is also better.
In addition to performance enhancements and the addition of the 4K/HDR mode, the PS4 Pro also supports Ultra HD streaming video playback capabilities. So if you are an old PS4 player, or are planning to get started with PS4 Pro, take a look at what the PS4 Pro does when compared to the PS4.
Design
First of all, the PS4 Pro and PS4 in appearance design, the most obvious change is an additional "layer", the previous PS4 uses a two-tier design, which is the disk drive and the host part, and provides two USB interfaces, and PS4 Pro becomes three layers.
Therefore, the size of the PS4 Pro has also changed from the original PS4 of 275.1 x 305.1 x 53.1 mm to 295 x 327 x 55 mm. It can be said that the PS4 Pro has a slight increase in length and width, but the height is not much changed, and the weight is about 0.5 kg.
Connectivity
The PS4 Pro's main interface is designed on the back, and there is not much change compared to the PS4, just an additional USB 3.0 interface. This is useful for users who plan to purchase a PlayStation VR, after all, without using an additional USB port.
In fact, the design of one more USB interface is also very intimate, after all, including the PlayStation VR back to the Move controller also requires a USB interface for charging.
In addition, unlike the PS4 Slim, the PS4 Pro retains the same optical audio output ports as the PS4, not the same as the PS4 Slim.
There is also a difference in the HDMI interface, the original PS4 uses the HDMI 1.4 interface, and on the PS4 Pro directly upgraded to HDMI 2.0, which allows the PS4 Pro to directly output 4K resolution screen. It should be noted that Sony has officially confirmed that users do not need to upgrade their original HDMI cable. The ordinary 1080p HDMI cable can be directly used to output the 4K resolution signal of the PS4 Pro.
Optical drive
This is a "disadvantage" of Sony's new console. As the latest PS4 Pro host, it does not support 4K ultra-high-definition Blu-ray disc playback. Like the PS4, it can only play 1080p Blu-ray discs.
Sony's direct ignorance of ultra-high-definition Blu-ray disc playback makes people feel puzzled. After all, in the PS3 era, being able to play Blu-ray discs was one of the biggest features. Now, Sony's renunciation of the 4K Blu-ray disc may become the biggest point of the Microsoft Xbox One S. Many people will therefore give up the PS4 Pro and put it into the embrace of Microsoft.
performance
The performance improvement is also the focus of many players. The first PS4 Pro and PS4 are all using AMD's Jaguar x64-64 eight-core processor, but the main frequency is increased from 1.6GHz to 2.1GHz, and the increase rate reaches 30%. At the same time, more improvement comes from the graphics card. Basically, PS4 Pro's graphics processing power is double that of the PS4, from 800MHz to 911MHz.
In the total floating-point computing capability of the video card, it also increased from 184 million times before the PS4 to 420 million times, and this is also to adapt to the 4K screen.
In terms of Wi-Fi connectivity, the PS4 Pro is upgraded to the 802.11ac standard, and the Bluetooth protocol has also been upgraded from the previous 2.1 to Bluetooth 4.0. Power consumption is lower, data transmission is more stable and faster, but Sony also performed on the PS4 Slim. This upgrade.
Finally, the PS4 Pro also added an additional 1GB of DDR3 memory, which also has some improvements in game performance and speed.
which performed
All paper parameters are actually not as direct as the actual comparison, and the PS4 Pro's output to 4K ultra-high-definition screen is undoubtedly the biggest increase compared with the PS4's 1080p.
When playing streaming video, PS4 Pro means that it can bring clearer, higher-quality picture support, but does not support 4K ultra-high-definition Blu-ray disc playback, undoubtedly limiting the needs of some advanced enthusiasts.
In terms of games, the factors of influence are more complicated. After all, developers need to additionally develop game versions of the 4K model. For example, based on previous news, basically the future game will have 4K/30fps and 1080p/60fps two different image quality options.
Like Days Gone, it has already indicated that it has completed the upgrade of 4K resolution. At the same time, there are some games that use direct stretching. However, any support for 4K will be a matter for developers to reconsider.
It is very important for developers how to balance the 4K performance and the picture, and what resolution rendering and upgrading techniques are used. After all, the performance of the PS4 Pro is not sufficient to directly resolve the resolution of all elements, so compromises and trade-offs need to be decided.
Although the PS4 Pro has also joined HDR support, Sony said that the PS4 will also have this feature through firmware upgrades in the future.
Summary: Upgrading is not a small leap
Although the PS4 Pro has many improvements compared to the PS4, there are still some compromises from the real 4K games.
The biggest difference in appearance design is "more layers", while the performance from the processor to the graphics card has improved a lot, including the main frequency and GPU's screen processing capabilities.
As for the old players of PS4, whether or not they should upgrade PS4 Pro depends on their own ideas. If you have plans to update your home TV to 4K Ultra HD in the future, PS4 Pro will undoubtedly bring a lot of improvement to the game screen. But if you don't want to invest in 4K Ultra HD TVs, then compared to the PS4, the upgrade of the PS4 Pro is not particularly necessary.
