Exynos 1580 unveiled with Cortex-A720 cores, double the GPU hardware
It uses ARMv9 cores, so A720 and A520 instead of A78 and A55. Also, the RDNA 3 GPU has two Work Group Processors, though performance hasn't doubled.

The CPU of the Exynos 1580 moves to a three-cluster design with one prime Cortex-A720 core (2.9GHz), three big A720 cores (2.6GHz) and four A520 (1.95GHz). This alone represents a major performance boost compared to the 1480, which used ARMv8 cores.
The GPU is based on AMD’s RDNA 3 architecture, now featuring two Work Group Processors – up from just one on the 1480 (the Exynos 2400 has six). Samsung says that maximum performance is up by 37% while performance at the same power level as the 1480 is up by 20%. This GPU also increases the GL2 cache.
The NPU delivers 14.7 TOPS of performance. The 1380 had just 4.9 TOPS, while the 1480 went up to... Samsung doesn’t say. However, both the 1480 and 1580 NPUs are described as “6K MAC”, so presumably there’s no difference. The spec sheet does say the new NPU has an increased cache capacity of 2MB, but the effects of that will only be known after benchmarks.

The new chip supports LPDDR5 RAM and UFS 3.1 storage. Connectivity is mostly the same with 5G (both sub-6GHz and mmWave), Wi-Fi 6E (ax) and Bluetooth 5.4. There is no AV1 decoder.

While they say the GPU hardware is double. What they mean is the Worker group increased from 1 to two. The GPU performance uplift is modest at 37% with it being 20% more efficient at the same power level as Exynos 1480. The NPU is described as "6K mac". Whatever that means..
All in all, Arm v9 upgraded cores and improved GPU performance.
