Experts look forward to Apple A14 chip: running points comparable to desktop CPUs

According to foreign news reports, according to foreign media reports, the highly anticipated Apple iPhone 12 currently has many rumors. It is expected that the design of the product will be similar to the iPhone 4 or the current iPad Pro style. The rear time of flight sensor can improve AR performance. And portrait mode, support 5G network, built-in 6GB RAM, A14 processor chip with 5nm process technology.

The industry predicts that the iPhone 12's performance will be as powerful as Apple's 15-inch MacBook Pro CPU.

In response to Apple's forthcoming A14 chip, Jason Cross, editor of media MacWorld, said that upgrading from a 7-nanometer process to a 5-nanometer process does not sound like much progress. In fact, this is really a major upgrade.

Cross said that this is a major upgrade. From 7 nanometers to 5 nanometers, it is not a leap in half-generation technology, but an improvement in one-generation technology.

Cross said, "According to TSMC, the 5-nanometer process will increase the transistor density of the chip. What we are seeing is an incredible 15 billion transistor density, which exceeds the density of powerful high-end desktops and servers. CPU and GPU. It doesn't surprise me that if Apple reduces the total area of ​​the (A14) chip to about 85 mm square and has a density of about 12.5 billion transistors, its performance will be strong enough. "

This configuration will make Apple's products even better, especially in terms of multi-core performance.

Cross said, "The multi-core running score of the A14 chip may be around 4500 points, but due to architectural changes and clock speed changes, the multi-core running score of the chip may exceed 5,000 points. After testing, the fastest Android phone currently has multiple cores. The running score is about 3000. A running score of 5,000 points is similar to a 6-core mainstream desktop CPU or high-end notebook CPU. This has actually reached the performance level of the 15-inch MacBook Pro.

More transistors in the GPU, and rumored faster 6GB RAM, can improve game performance by about 50%.

Cross said, "I expect that Apple will increase transistor density to make the GPU more powerful. With more memory bandwidth, we may expect GPU performance to far exceed the minimum multi-core benchmark score of 7000. In addition to some new performance The bottleneck, I think it is definitely possible to achieve more than 9,500 points. In other words, I think that for high-end graphics chips used in games, we can expect a 50% improvement in graphics performance. "

Cross also expects that the A14 chip will have a bigger change in another area, namely the neural network.

Cross said, "With the higher transistor density provided by the 5nm manufacturing process, I think Apple will add a neural network core this time and may make other architectural improvements. As Apple claims, the speed of the A14 machine learning task may be At least twice as much as A13. "
