ARM has unveiled new series of cores, Cortex-A78 successor to Cortex-A77 and a whole new program for custom Core design known as Cortex-X1. This approach from ARM might give a tough time Apple’s A14 chipset.
Let’s straight dive into the details of custom program of Cortex-X1 series.
ARM has introduced a new program in which vendors can directly work with ARM to make their own cluster of Cortex-X1 for peak performance. It is same as Apple’s Lightning cluster found in A13 chipset.
As we can see the Cortex-X1 has 22% higher performance over the new Cortex-A78 and 30% higher performance than Cortex-A77, which is a huge jump. On the other hand vendors can use up to 8MB of L3 cache when using Cortex-X1 cores with A78 and low power A55 cores. Plus two times machine learning performance as well.
Now vendors can customize and choose between the peak performance or conventional , vendors can choose many possibilities like 1x Cortex-X1, 3x Cortex-A78 and 4x low performance Cortex-A55 cores, or companies can count on 2x Cortex-X1, 2x Cortex-A78 and 4x Cortex-A55.
Now let’s take a look at the new Cortex-A78 improvements. The Cortex-A78 is 20% more powerful than Cortex-A77 and 50% more efficient than its predecessor. This comparison shown by ARM is based on same wattage consumption but the new Cortex-A78 cores are built on 5nm process as shown below.
On the GPU side ARM has unveiled Mali-G78 and G68, The G78 GPU is still based on the old Valhall architecture, but ARM claims 25% better performance in some specific areas compared to G77, plus G78 can carry up to 24 cores. According to ARM G78 performance in games is up to 17% better than its predecessor, and G78 is more efficient as well.
The Mali-G68 inherits all features from its big brother G78 but its capped up to 6 core design instead of 24 cores, and it is also more efficient as it is not as power hungry like G78. Mostly mid-range chipsets will use Mali-G68.
