Despite many people saying otherwise, it appears that the Exynos 2400 is real and could power the Samsung Galaxy S24 next year. Unlike its predecessors, it is a ten-core CPU packed to the brim with new Arm CPU cores. It gets a new RDNA-based Xclipse 920 GPU, too. A slew of new leaks now shed light on its performance, and it is nothing short of stellar.
Twitter leaker @OreXDA has discovered the Exynos 2400 scores 13,858 points in Geekbench's Vulkan Benchmark, a smidgen higher than the Snapdragon 8 Gen 3 (12,946). In OpenCL, the Samsung chip nets a score of 26,829. That is more or less on par with an Nvidia GeForce MX350, which is impressive for a smartphone GPU. Then again, Geekbench isn't the best test to measure the performance of any GPU, but this is the only frame of reference available now.
The Exynos 2400's clock speed is set at a blazing-fast 1,756 MHz, a tad lower than the 2.0 GHz figure predicted by an earlier leak. Decompiled kernel source code (h/t @QaM_Section31) reveals, it is supposedly codenamed Gfx1040, confirming it is based on the RDNA2 architecture. Incidentally, even the Steam Deck uses a Van Gogh Lite GPU, although it'll be very optimistic to expect Steam Deck levels from an Exynos 2400.
