Arm aims for the laptop market with new processors


The prime highlight of the newly launched line-up is the Cortex A76 which according to company's claims, will double the performance of ARM laptops in the near future and it will do so without eating a lot of power.

If the figures are accurate, the Cortex-A76 could result in ARM-based Windows 10 machines that actually challenge Intel/AMD-powered device. More technical details about the new GPU can be read here.

Arm's latest graphics part features a number of other smaller optimizations, including out of order polygon list writeback to prevent stalls during cache misses, varying pre-loads to improve efficiency and depth pre-loads for better multi-render performance, and TLS Address interleaving to improve the speed of cache fetching by better organizing the memory space.

ARM also announced the Mali-G76 GPU. As ARM has constantly delivered 20-25% performance improvements for its CPUs on a year-by-year basis for the last 5 years now, the next few years will be crucial for the advent of the first desktop-grade CPUs fit into mobile chips.

Before we get into more detailed breakdowns of the performance and power improvements and what I'm expecting to happen into products, let's see the microarchitectural improvements on the core and how Arm managed to extract this much performance while maintaining power efficiency.

The company says that its new Cortex-A76 CPU and Mali-G76 GPU will bring laptop-level performance to smartphones in terms of computing and graphics power whilst offering great power efficiency and battery lifespan for larger devices such as always-on laptops. Now ARM did indicate that this was being compared against Cortex-A75 clocked at 2.8GHz on the 10nm process, while the Cortex-A76 was a 3GHz on the 7nm process.

Each year new flagships come out with new chipsets, which in turn require new cores. The company is promising 30 percent more efficiency and 30 percent performance density.

It also has 2.7 times the machine learning capacity with four times the performance as artificial intelligence is relied on for things such as particle effects.

Finally, the Mali-V76 is the company's new video processing unit, and it is able to do up to 8K video at 60fps.

This will allow consumers to watch four games, watch four movies, or record video in 4K. And at lower resolutions, and still at full HD, Mali-G76 will support up to 16 streams of content, creating a 4x4 video wall, a very popular use case in the China market, the company noted. It has twice the decode performance and capability of the old Mali-V61, but a 40-percent smaller footprint.
