Arms recently announced the Immortal-G715 GPU for mobile platforms, which is also the company’s first graphics unit to support hardware ray tracing. However, this is not the first arm GPUs to offer laser trace support as the Mali-G710 GPU, which was launched by the company in 2021, also included the technology, reports The Verge. Meanwhile, the company claims that the ray tracing offered with the Mali-G710 GPU was entirely software-based, but the latest GPU will support hardware-accelerated ray tracing.
Arm’s attempt to improve mobile games
Ray tracing has been trending in the gaming world for a long time. This technology is an integral part of the GPUs integrated into modern PCs or the latest generation consoles. According to a report from 9to5Google, Arm is now trying to make ray tracing more popular on android smartphones with its new Immortalis-G715 GPUs.
What is Ray Tracing technology and how does it provide a better gaming experience
According to the report, ray-tracing technology, which was initially popularized by PC gaming, is a feature that aims to make lighting effects more realistic. This technology tries to improve the lighting effect that hits a subject depending on a scene or the lighting around the reflections that can be seen on the floor or in a glass. According to Nvidia’s explanation, “ray tracing is a graphical rendering method that simulates the physical behavior of light.”
Arm also explained the characteristics of Ray Tracing using demonstration videos. According to the company, “Immortalis-G715 is the first Arm GPU to offer hardware support for Ray Tracing designed specifically for mobile.” Arm mentioned that Ray Tracing is a “computer graphics technique” that produces near-real lighting and shadows by “modeling the paths that individual light rays take around a scene.” The company further explains that this technology is key to delivering “more realistic gaming experiences”.
New GPUs announced by Arm
Arm recently announced a flagship GPU – Immortalis-G715 – and two new premium GPUs – the Mali-G715 and Mali-G615. The flagship GPU design is based on the standard Mali architecture, however, Immortalis has more cores than the latest Mali units. To compare, the Immortalis-G715 GPU offers 10 to 16 cores, while the Mali-G715 offers seven to nine cores and the Mali-G615 comes with less than six cores. Additionally, Malian units also do not support ray tracing. Apart from that, the new Immortalis-G715 GPU is also expected to deliver around a 15% performance boost over its previous high-end unit while promising 15% more power efficiency, Arm claims.
Availability of new Arm GPUs
The company claims that Android smartphones with Immortalis-G715 GPUs integrated into their chips are expected to arrive in early 2023. However, this GPU will only be available for the next MediaTek chipsets as Qualcomm uses its proprietary Adreno GPU designs, the report mentions.
The future of ray tracing in mobile games
The report suggests that Arm’s first hardware-accelerated GPU with ray tracing isn’t the first unit to hit the market. Samsung worked with AMD to develop the GPU for the Exynos 2200 chipset which also supports this technology. The importance of ray tracing has pushed Samsung and Arm to adopt this gaming technology. The availability of ray tracing will allow more Android games and developers to incorporate the technology into their titles, according to the report.
However, it is important to note that currently this technology is very rare outside of PC gaming. Except that, epic games and Unity also extended their ray tracing support being adopted in more smartphone games. The report also mentions that games developed using the Unreal Engine will “quite easily take advantage” of this technology.
