ARM unveils 3 new GPUs including Immortalis-G715 with ray tracing support

ARM reveals Mali-G615, G-715, and the Immortalis-G715, the company's first GPU with hardware ray-tracing capabilities.

Three new GPUs from ARM!

Ray Tracing technology is a significant factor for the current generation of consoles, and desktop GPUs and now it has made its way to mobile platforms.

The new mobile graphics features

According to the chipmaker, the "Immortalis" is a new Flagship GPU line but they reiterated that the popular "Mali" GPUs won't go away in fact, ARM said there are also two more designs for premium and mid-range devices.

The Immortalis-G715 will also be the chipmaker's first GPU to have the hardware acceleration for ray tracing. Even though last year's G710 could perform this in software, hardware support is essentially a game-changer as it uses only 4 percent of the shader core area while enhancing performance by river 300 percent.

New Mali graphics for flagship and midrange

Aside from the Immortalis GPU, ARM also introduces the Mali-G715 and the Mali-G615. The differences between these will be the core counts, the G615 gets 6 or less, while the G715 has 7-9 cores. However, the Immortalis gets 10 or more cores.

The three of them support VRS or Variable Rate Shading which allows game makers to tell the GPU where to focus its power so that it can render things at a full resolution like the player character, and where to take shortcuts on other tasks like the background.

Frame rates can rise by up to 40 percent when it's executed right while also maintaining the same visuals of the game. Another thing is this can also be utilized to drastically cut power consumption in its place, which is crucial for the battery of the phone. Meaning it does the job more efficiently.

Additionally, each of the three GPUs has an upgraded execution engine that will increase performance by 15 percent, making them the fastest ARM GPUs yet.

ARM uses the FMA or also known as the Fused Multiply-Add. With this, the company manages to double the performance of the FMA blocks while only seeing a 27 percent size increase. The Matrix Multiply Instruction is a brand-new function that is essential for picture enhancement and computational photography. The performance of machine learning on the new GPUs is two times that of the previous generations.

The manufacturer of mobile GPUs has also made other advancements, such as increasing triangle throughput and integrating the texture-saving ARM Fixed Rate Compression (AFRC).

Finally, To develop new graphic technologies, ARM is also collaborating with Unity and Epic. Which are the producers of the two popular game engines for PCs and mobile.

You may expect the three new mobile graphics for the upcoming chipsets next year.
