AMD recently pulled the wraps off its Radeon 6800M mobile graphics series that uses RDNA 2 graphics technology. Samsung partnered with AMD to bring Exynos-powered Samsung phones on par with its Snapdragon boasting sibling. Exynos always fell behind Snapdragon in terms of Graphics performance. At Computex Taipei, AMD announced its partnership with Samsung to bring RDNA 2 graphics for Exynos SoC.
What is RDNA/RDNA 2?
RDNA is a GPU microarchitecture used by Radeon and if you wonder what RDNA means, RDNA simply stands for Radeon DNA. RDNA was based on TSMC’s 7nm FinFET graphic chips and was used in the Navi series of AMD Radeon graphics cards. The Radeon RX 5000 Series GPU marked the era for RDNA.
Coming to the RDNA 2, you guessed it right, this is a successor to RDNA microarchitecture which was announced in Q4 2020. AMD claims that this new architecture will give you a 50% performance-per-watt gain over its predecessor and will have increased clock speed and instructions-per clock. AMD’s Radeon RX 6000 series GPUs are the prime examples of chips based on RDNA 2 architecture.
P.S. RDNA 3 is scheduled to make a debut later this year.
RDNA 2 x Exynos:
The details regarding this crossover are scarce but it is known that these next-gen Mobile GPUs from AMD will support ray tracing and Variable Rate Shading (VRS). With the Radeon RX6000 M series, GPU for mobile devices unveiled, we know the potential it packs. That’s the reason why AMD CEO Lisa Su’s statement,” The next place you’ll find RDNA 2 will be the high-performance mobile phone market” spread like wildfire resulting in all the hype that you see online. Especially for the Ray Tracing and VRS capabilities, it claims to offer.
What is Ray Tracing and Variable Rate Shading?
RayTracing is a rendering technique based on 3D modeling optics that can trace an image on the basis of the path of light. Simply put, it gives you a realistic-looking image with a realistic simulation of lighting and even sounds in some cases.
Variable Rate Shading (VRS) is also a rendering technique that allows GPUs to use different processing cores simultaneously to render complex parts of an image. In simpler terms, this technology makes games and programs a little less taxing on even low-end GPUs and can boost frame rates, given that they support VRS, to begin with.
Regardless of these fancy-termed bells and whistles, in order to take advantage of these features, even game developers will have to bring support for Ray Tracing as well as VRS. Or else, it is as good as having a 5G phone at a place without proper 4G.
When can we expect to see one?
Samsung’s current flagship chip, the Exynos 2100 SoC is already out and it features an ARM-designed Mali-G78 GPU, which leads us to believe that hopefully, Exynos 2200 from Samsung will be the pioneer of this crossover. Sticking to that assumption, we might see an Exynos Chip with AMD RDNA 2 mobile graphics later this year.
