The data-transfer rates from the modems are the same, with download speeds of up to 600Mbps (bits per second), and upload speeds of 150Mbps. The Snapdragon chip is more versatile because it is among the first to support LTE-U, in which faster data transfers can take place over both licensed and unlicensed spectrum.
The Snapdragon 820 will come in quad-core configurations, while the Exynos could have up to eight cores. The Snapdragon 820 also supports WiGig wireless technology, which is roughly up to three times faster than Wi-Fi in wireless data transfers, but that feature could be shut off so the handsets give customers similar speeds.
