Samsung tested a phone running its own Exynos 2700 chip against two Xiaomi phones with Qualcomm's newest chips, and the Exynos came out ahead on multi-core speed and on graphics. Korea's Chosun Biz reported the results, as Android Authority relays them. The Exynos 2700 is the chip expected in the Galaxy S27 phones Samsung sells in Korea and Europe.
Against the Xiaomi 18 Pro Max, which runs the Snapdragon 8 Elite Extreme Gen 6, the Exynos phone scored 20% higher in Geekbench 6.5's multi-core test and 15% higher in Geekbench 7.0. The gap was wider against the Xiaomi 18 Pro and its Snapdragon 8 Elite Gen 6: 44% and 36%.
Chosun Biz says the Exynos also beat the Snapdragon 8 Elite Gen 6 phones on graphics, by smaller margins. It was about 20% faster at "maximum processing performance of high-end games using the latest graphics technology" and 5% faster at "basic graphics computation performance" in ordinary 3D games. It didn't name the tests behind either number.
The Exynos 2700 is tipped to have ten CPU cores, two C2-Ultra and eight C2-Pro, while the Snapdragon 8 Elite Gen 6 has eight, so a multi-core win is the one you'd expect.
The Exynos 2700 is tipped to have ten CPU cores, two C2-Ultra and eight C2-Pro, while the Snapdragon 8 Elite Gen 6 has eight, so a multi-core win is the one you'd expect. What's missing is single-core speed, where Qualcomm has usually come out ahead of Samsung, and the report gives no figure for it.
It also doesn't say whether the graphics runs were one quick pass or a long stress test. A quick pass shows a chip's peak. A 20-minute run shows whether it can hold that speed once it warms up, which is what a long gaming session feels like. There's no word on heat or battery life either.
Seoul Economic Daily has already reported that the Snapdragon 8 Elite Extreme Gen 6 ran hotter than Samsung allows during long, demanding tasks in its final testing for the Galaxy S27 Ultra. So the sustained numbers, for both chips, are the ones that will decide which S27 is the better phone.
The comparison was also only against Xiaomi's phones. Other Snapdragon phones tune their chips differently and keep them cool in different ways, so a Galaxy S27 with a Snapdragon inside won't necessarily score the same as a Xiaomi 18 Pro.
If you buy your Galaxy in Korea or Europe, you'll most likely get the Exynos model, and Samsung's own numbers put it ahead where it has usually trailed. Wait for reviews before reading too much into it. The scores to look for are single-core speed, a long gaming test and battery life, because those are the three this report leaves out.
