There are multiple versions of both these phones in circulation—but we opted for US models with 5G mmWave to bring you the most complete-est teardown for your money. Our specs include:

Snapdragon 865+ processors paired with 8 GB (Note 20) or 12 GB (Ultra) of LPDDR5

Infinity-O AMOLED displays—6.7" (2400 × 1080) on the Note 20, and 6.9" (3088 × 1440) on the Ultra with 120 Hz refresh rate

128 GB of internal storage, plus up to an extra 1 TB on the Ultra via microSD

Four cameras each, including a 10 MP selfie and 12 MP ultra-wide. The vanilla Note 20 also gets a 12 MP wide-angle and a 64 MP telephoto, while the Ultra packs a 108 MP wide-angle and a 12 MP periscope telephoto with 5x optical zoom

Batteries: 4300 mAh in the Note 20, and 4500 mAh in the Ultra

5G and Ultra Wide Band connectivity, plus 4x4 MIMO LTE, 802.11ax Wi-Fi, and BT 5.0

Right off the bat, we'll peer deep into the Ultra with the power of X-rays (hat tip to our ingenious friends at Creative Electron for these images).
