It seems the global Samsung Galaxy S4 3G-only model outperforms the US model according to benchmark tests run by the folks at SamMobile. The international GT-I9500 running a Samsung’s Exynos 5 Octa clocked in at 1.6Ghz has outperformed the US GT-I9505 running Qualcomm’s Snapdragon 600 clocked at 1.9Ghz. The more powerful Korean variant, the SHV-E300S, has an Exynos 5 Octa clocked in at 1.8GHz but has yet to be tested.
On the Antutu benchmarking app, the international Galaxy S4 scored a whopping 28018 points while the US Galaxy S4 scored 23607 points. However, the performance difference will be negligible in day to day tasks. The Exynos 5 Octa difference will only be noticeable during high CPU-extensive app and slightly be more power efficient due to ARM’s big.LITTLE technology. The only disadvantage with the international model would be the lack of 4G/LTE. The Korean variant is expected to score around 30000 points, which could make it the fastest device in the market.
