ARM recently introduced its CPUs to be used in new generation flagship chipsets. These CPUs come with significant performance and efficiency improvements. What kind of performance increase will there be on the flagship devices of 2023? Will these anticipated new CPUs meet expectations? The performance of Cortex-X3, Cortex-A715 and renewed Cortex-A510, which will be used in the new generation flagship chipsets of Qualcomm and MediaTek, is very curious. Without further ado, let’s take a quick look at the Cortex-X3, Cortex-A715 and the refreshed Cortex-A510.
ARM Cortex-X3 Specifications
The new Cortex-X3, the successor to the Cortex-X2, is the 3rd core in the Cortex-X series designed by the Austin Texas team. Cortex-X series cores always aim to offer extreme performance with large size, higher power consumption. The new Cortex-X3 has a decoder that has been upgraded from a width of 5 to a width of 6. This means it can now process 6 commands per instruction. The “Branch Target Buffer” (BTB) in this new core appears to have been enlarged more than the previous Cortex-X2. While L0 BTB grew 10 times, the capacity of L1 BTB increased by 50%. The branch target buffer provides a significant improvement in performance by anticipating and fetching large instructions. Accordingly, ARM states that the latency has decreased by 12.2% compared to the Cortex-X2.
Also, ARM says that the size of Macro-Op (MOP) memory has been reduced from 3K to 1.5K inputs. Reducing the pipeline from 10 to 9 cycles reduces the likelihood of incorrect predictions and significantly improves performance. Maximum L1-L2 cache capacities remain on par with Cortex-X2, while ROB size has been increased from 288 to 320. With these improvements, ARM states that it can deliver 25% better peak performance than the current best flagship devices. We will tell you in detail whether this is true in the new generation devices that will be introduced over time.
ARM Cortex-A715 Specifications
The successor to the Cortex-A710, the Cortex-A715 is a sustainable performance-oriented next-generation core designed by the Sophia team. At the same time, we need to mention that it is the first mid-core to remove Aarch32 support. Being unable to run 32-bit supported applications, the Cortex-A715 is now fully optimized on a core basis for 64-bit supported applications.
The decoders that enabled them to run 32-bit applications on the Cortex-A710 are now renewed in the Cortex-A715 and can only run 64-bit supported applications, resulting in a reduction in the size of the decoders. Compared to the Cortex-A78, this new core has a 4-width to 5-width decoder, allowing for a 5% increase in performance and a 20% increase in power efficiency. This reveals that the Cortex-A715 can now perform similarly to the Cortex-X1. We can describe the Cortex-A715 as a further developed Cortex-A710.
Refurbished ARM Cortex-A510 Specifications
Finally, we come to the refreshed Cortex-A510 in CPUs. ARM has re-announced the Cortex-A510, designed by the Cambridge team, which it introduced last year, with some minor changes. While the Cortex-A510, which was introduced last year, does not have Aarch32 support, this support can be optionally added to the renewed Cortex-A510. We know that there are still 32-bit supported programs.
Since Aarch32 support has been removed in Cortex-A715, it is a nice detail that this support can be optionally added to the renewed Cortex-A510. The updated Cortex-A510 core consumes 5% less power compared to its predecessor. It can see this new CPU core as a core-optimized version of the Cortex-A510 that will be used in flagship chipsets in 2023.
ARM Immoralis-G715, Mali-G715 and Mali-G615 GPU
In addition to the CPUs it introduced, ARM also announced its new GPUs. The Immoralis-G715 GPU, which has the first “hardware-based Ray Tracing” technology on the ARM side, is quite remarkable. Supporting a maximum of 16 core configurations, this GPU offers Variable Rate Shading (VRS). It improves performance and reduces power consumption by reducing shadows according to certain scenes in games. This feature positively affects the user experience.
MediaTek made the following statement about this new GPU. “Congratulations to Arm on the launch of the new Immortalis GPU, featuring hardware-based ray tracing. Combined with the new powerful Cortex-X3 CPU, we look forward to the next-level of mobile gaming and productivity for our Flagship & Premium mobile SOCs” This statement shows us that the new MediaTek SOC, which will be used in 2023 flagship devices, will feature the Immoralis-G715 GPU. It is a development that will positively affect the course of the mobile market. The Immoralis-G715 GPU improves performance and power efficiency by 15% compared to the previous generation Mali-G710.
In addition to the Immoralis-G715 GPU, new Mali-G715 and Mali-G615 GPUs were also announced. Unlike Immoralis-G715, these GPUs do “not have hardware-based Ray Tracing” support. They only have Variable Rate Shading (VRS). The Mali-G715 supports a maximum 9-core configuration, while the Mali-G615 supports a 6-core configuration. The new Mali-G715 and Mali-G615 offer a 15% performance increase over their predecessors.
