Now, the Exynos 2200 is finally official. The headline feature is a new "Samsung Xclipse 920 GPU" that was co-developed by AMD. Samsung says the GPU uses AMD's RDNA 2 architecture, the same as AMD's Radeon desktop GPUs, and will bring "hardware-accelerated ray tracing" to mobile devices.
David Wang, the SVP of AMD's Radeon division, said, "Samsung's Xclipse GPU is the first result of multiple planned generations of AMD RDNA graphics in Exynos SoCs." Previous reports have indicated that Samsung isn't just eyeing smartphones but eventually wants to put together an Apple M1-fighting ARM laptop chip.
The CPU is about what you would expect from a 2022 ARM chip. The 4 nm SoC has one Cortex X2 CPU for single-threaded performance, three Cortex A710 cores, and four low-power Cortex A510 cores, just like Qualcomm's 2022 chip, the Snapdragon 8 Gen 1. These are all new ARM v9 cores, with the X2 and little cores both being 64-bit only.
Despite finally announcing the Exynos 2200, Samsung's announcement does not put to bed any questions about a troubled development of the Exynos 2200. The press release and product site are both lacking many of the details that are typically disclosed at this point. For instance, Samsung has not made any performance claims about the Exynos 2200 CPU or GPU. If you read through the Exynos 2100 press release from this time last year, you'll see claims like 30 percent better CPU multi-core performance and 40 percent faster graphics.
Leaks have pointed to thermal issues with the Exynos 2200 which could potentially lead to lower performance than its main competitors: Qualcomm's Snapdragon 8 Gen 1, MediaTek's Dimensity 9000, and Apple's A15.
The fate of Samsung's custom CPU development efforts has been making the rounds of the rumour mill for almost a month, and now we finally have confirmation from Samsung that the company has stopped further development work on its custom Arm architecture CPU cores. This public confirmation comes via Samsung's HR department, which last week filled an obligatory notice letter with the Texas Workforce Commission, warning about upcoming layoffs of Samsung's Austin R&D Center CPU team and the impending termination of their custom CPU work.
The CPU project, said currently to be around 290 team members large, started off sometime in 2012 and has produced the custom ARMv8 CPU microarchitectures from the Exynos M1 in the Exynos 8890 up to the latest Exynos M5 in the upcoming Exynos 990.
Over the years, Samsung's custom CPU microarchitectures had a tough time in differentiating themselves from Arm's own Cortex designs, never being fully competitive in any one metric. The Exynos-M3 Meerkat cores employed in the Exynos 9810 (Galaxy S9), for example, ended up being more of a handicap to the SoC due to its poor energy efficiency. Even the CPU project itself had a rocky start, as originally the custom microarchitecture was meant to power Samsung's custom Arm server SoCs before the design efforts were redirected towards mobile use.

Qualcomm today unveiled the Snapdragon 8cx Gen 3 and Snapdragon 7c+ Gen 3 Compute Platforms that will power the next wave of Windows-on-ARM Always On Always Connected PCs. The Snapdragon 8cx Gen 3 is the first 5 nm SoC for the PC and features a 4+4 CPU with Cortex-X1 and Cortex-A78 cores along with other Qualcomm connectivity and security features.
[...] With the Snapdragon 8cx Gen 3, PCs are all set to get their first taste of the 5 nm architecture albeit on ARM. According to Qualcomm, the Snapdragon 8cx Gen 3 is about 85% faster in CPU and 60% faster in GPU performance. The exact comparative parameters were not disclosed during the presentation, however.
The Snapdragon 8cx Gen 3 is also slated to offer 29+ TOPS of AI performance. Once again, the comparisons aren't really obvious, but we can hazard a guess that this could be with respect to the Snapdragon 8cx Gen 2.
Previously, ARM SoCs have had only a single Cortex-X core, with the exception of Google's Tensor, found in the Pixel 6, which has 2x Cortex-X1 cores.

At this year's Tech Summit from Hawaii, it's time again for Qualcomm to unveil and detail the company's most important launch of the year, showcasing the newest Snapdragon flagship SoC that will be powering our upcoming 2022 devices. Today, as the first of a few announcements at the event, Qualcomm is announcing the new Snapdragon 8 Gen 1, the direct follow-up to last year's Snapdragon 888.
