AMD has made a number of major product announcements at the Computex 2021 trade show. During the keynote, the CEO talked about bringing AMD’s RDNA 2 graphics architecture to Samsung’s Exynos chipsets later this year with an advanced feature that we’ve only seen on gaming consoles so far. Samsung could have the strongest GPU performance of any smartphones out there.
Samsung has already confirmed that for the CPU side of the things they will be using brand new ARM V9 architecture and also use the brand new High performance super core that is Cortex X2. Now AMD has officially confirmed that Samsung will be announcing all details for this next generation Exynos processor later down the year. It’s very likely that this announcement will happen towards the end of the year and then we will be seeing this brand new AMD RDNA 2 GPU on upcoming Samsung Galaxy S22 line up.
AMD has mentioned two key specifications of the new GPU. Ray tracing and variable rate shading.
Ray tracing is a rendering technique that can produce incredibly realistic lighting effects. We’ve seen in-game lighting effects become more and more realistic over the years, but the benefits of ray tracing are less about the light itself and more about how it interacts with the world. Ray tracing allows for dramatically more lifelike shadows and reflections, along with much-improved translucence and scattering.
The algorithm takes into account where the light hits and calculates the interaction and interplay much like the human eye would process real light, shadows, and reflections, for example. With enough computational power available, it’s possible to produce incredibly realistic CG images that are nearly indistinguishable from real life.
Of course, you can’t expect details like this in mobile games but the fact that AMD’s RDNA 2 supports ray-tracing means this is one hell of a powerful GPU and AMD is certainly setting expectations high for future Samsung devices.
The second thing they mentioned is variable rate shading.
This allows objects that are out of the focus of attention or are deep in the background can be rendered at lower fidelity. All of the GPU power that was used to fully shade objects not being looked at is freed and can be used to enrich what is being looked at or increase frame rate. This increases the game performance and efficiency of the phone as well since GPU power isn’t being wasted on things that you’ll never pay attention to.
Qualcomm has already introduced variable-rate shading on the Snapdragon 888 so it isn’t something new to the smartphone world, but ray tracing is and this will take smartphone gaming to a different level and it also basically confirms the benchmarks we’ve been seeing where the AMD GPU destroys both Apple’s and Snapdragon’s graphics is probably true.
So really looking forward to it, AMD said Samsung will launch the chipset later this year and will provide all the details. So don’t expect the Galaxy Z Fold 3 to feature this chipset, instead the Galaxy S22 next year will be the first smartphone to officially have the RDNA 2 graphics.
With that said, Xiaomi has just broken the world record for the fastest charging solution on a mobile phone. They showcased their new 200W HyperCharge charging technology that can charge at mind-boggling speeds. As the video demonstrates, the 200W charger can get a 4,000mAh phone battery to 10% in 44 seconds, 50% in three minutes, and 100% in just eight minutes.
You heard that right, just mere 8 minutes. Of course, there is one potential downside to this extremely fast charging, and that’s battery health. We don’t know how pushing so much energy into a battery so quickly impacts the lifetime of a battery. Hopefully, we will get a deeper dive into the HyperCharge tech soon.
