The quad core revolution has already begun, and Samsung is the latest contender to come out with a quad core processor on the Samsung Galaxy S III with its Exynos 4 to compete with nVIDIA’s Tegra 3. Quad core does not necessarily mean better performance than a dual core, however. Many reviewers have also noted that the dual core S4 processor from Qualcomm performs better than the quad core Tegra 3 processor in a number of benchmarks. Anyway the Samsung Galaxy S III is about to be launched in the U.S, but instead of the Exynos 4 processor, this version of the S III will be coming with a dual core S4 processor.

Samsung has always produced application processors, which does not include the radios for American LTE networks. Their production model has always been to introduce devices without LTE modems in the countries which do not use LTE and introduce LTE modem embedded SoCs in their devices for the countries which have LTE networks.

The Exynos 4 quadcore processor is an application processor which does not carry an LTE modem with the chipset. While the Krait based Snapdragon S4 processor by qualcomm is a dual core processor but packs an LTE modem in the SoC which is the main reason why Samsung decided to go with the dual core SoC in the U.S. A similar model is used by HTC where the global models of the HTC One X come with a quad core Tegra 3 processor while the American version of the One X packs the S4 processor.

The S4 processor will make the device slightly thicker because of a larger dye. Other than that U.S version will have 2 GB of RAM instead of 1 GB RAM available in global version. One good thing done by Samsung is that these variants of dual core SGSIII are being manufactured and produced much faster. When compared to the time taken to produce the SGSII last year. Also the S4 processor is said to have a better architecture than the other quad cores and better performance, as well as generating less heat.

It will be really interesting to see how well the processor is integrated with Samsung’s software and the Android OS. Dual core or quad core, the final verdict lies on how well the device performs. We will be waiting for the dual core SIIIs to come out pretty soon, review them, and provide our readers more information about what we think about the device.
