In the world of very low power processors, it is difficult to find CPUs from Intel and AMD, leaving this area to others. Specifically, mobile processors, with ARM architecture, which are at the heart of laptops and smartphones. Now a new generation is coming, led by the Cortex-X3 of RMApromising up to 22% more performance compared to the last generation.
The battle in the mobile processor market is tough, with the need for constant innovation in a market that is advancing by leaps and bounds. Therefore, the need to develop new CPU which improve both energy and performance, has become a necessity if you want to be a market leader. To achieve this, ARM has announced two new processors based on its architecture armv9called Cortex-X3 and Cortex-A715.
The ARM Cortex-X3 offers 34% more performance than an Intel Core i7-1260P
Harsh statements, if true, considering they come from ARM itself, plus just the CPU Intel Core i7-1260P will be 28W (PDT base). We would speak of a processor of 12 heartsdivided into 4 high-performance cores (P-Cores) Yes 8 efficient nuclei (e cores), totaling 16 sons. This would go to a maximum turbo frequency of 4.7GHz in the P-Cores and 3.4GHz in the case of E-Cores.
Although it is not the highest range belonging to the architecture Alder Lake for laptops, it is quite competitive in its industry which is impressive. Of course, it must be taken into account that they mention 28W, without knowing if it is a reference to consumption without turbo increase activated or if it is the total consumption. Let’s also not forget that 25% extra performance they claim to have over mobiles android current top of the range, yes, without giving details of the models.
Up to 12 cores at 3.6 GHz with 16 MB L3 cache, in addition to being more efficient
And that’s it, this ARM Cortex-X3 promises, and a lot, with configurations up to 12 hearts to a maximum of 3.3GHz on mobile devices and 3.6GHz on laptops. About memory hiddenhas an increase in it, reaching 16 MB L3while the L2 cache seems to agree with 1 MB. With this, it is clear to us that his scalable designwill allow manufacturers to have greater flexibility and to be able to make different configurations depending on the device.
Also, as seen in the comparative graph against the Cortex-x2, the new generation of CPUs will consume less power, especially by putting more cane into it. The exact data is not provided, but we see a big difference in consumption once Cortex-X2 reached its peak of performance. For its part, the Cortex-X3 maintains an increase in consumption quite restrained in the left half as far as low frequencies are concerned.
The Cortex-X3 increases its IPC by 11% and the Cortex-A715 by 20% its energy efficiency
That’s right, it seems that the increase in performance of the ARM Cortex-X3 is due in part to an increase in Eleven% of CPI. Additionally, you get a 22% return extra when you squeeze it to the max, comparing it to the Cortex-X2. But we have already talked enough about the most powerful CPU that ARM has presented, leaving behind another equally interesting one, the Cortex-A715.
This would fill the CPU slot balance between consumption and performance, without reaching the X3, but if ARM Cortex-X1, the high-performance processor celebrating its 2nd anniversary. To achieve this, they increased their Efficiency energy in a twenty%can increase the performance in one 5% respect to Cortex-A710.
Now, the use of the evolutionary design of these processors is the way in which the union of the two ARM processors is most used. For example, with the maximum 12 heartsit would be possible to combine 8 Cortex-X3 cores with 4 Cortex-A715 cores and get good performance and power consumption in laptop.
