Samsung recently launched its new flagship Galaxy S4 smartphone, and users will be able to pre-order it from several US carriers later this month.
AT&T customers will be able to pre-order the 16GB Galaxy S4 for $199.99 and 32GB model for $249.99 beginning April 16. Those prices are contingent on a two-year contract. US Cellular will also be carrying the new flagship smartphone, but has not announced how much it will cost. Customers can register to be notified when it becomes available, however. T-Mobile is also going to offer the Samsung Galaxy S4, but customers will need to pay full price. According to UK mobile site Phones Review, T-Mobile will offer the smartphone on its new no-contract plans for $99 plus a $20 per month fee until it is paid off starting May 1. Regrettably, there is no word on when (or whether) a Verizon or Sprint-comparable model will show up.
Of course, the Samsung Galaxy S4 offers up the following specifications. On the outside, the phone features a 5” Super AMOLED screen with a resolution of 1920 x 1080 and Gorilla Glass 3 protection. A 2MP webcam and 12MP auto-focus camera with LED flash are also included. The internals of the phone are also impressive, with a Qualcomm Snapdragon 600 SoC, 2GB of RAM, and up to 64GB of internal storage (expandable via microSD cards). The 2,600 mAh battery seems a bit weak compared to the one in the Galaxy Mega 6.3, but space constraints likely limited the battery size despite the beefier processor and higher-resolution display. Sensors and I/O include accelerometer, gyroscope, proximity, compass, barometer, temperature, humidity, and gesture. Wireless radios include a cellular modem (4G LTE, 3G HSDPA), A-GPS+GLONASS, dual band 802.11a/b/g/n/ac, NFC, and Bluetooth 4.0. The Qualcomm 600 SoC consists of a quad core Krait 300 processor clocked at 1.9GHz and an Adreno 320 GPU.
Note that the US version does not use the higher-performance Samsung Exynos 5 Octa SoC. For reference, the international model's SoC has the following features:
The Exynos 5 Octa consists of a PowerVR SGX 544MP3 GPU and both a quad core Cortex A15 clocked at 1.6GHz and a 1.2GHz Cortex A7 processor with four cores. The two ARM processors are configured in big.LITTLE configuration, so technically it is still a quad core phone--but the lower-power Cortex A7 cores will be used for background tasks and/or to save power while shutting down the Cortex A15 cores when CPU load allows.
The Galaxy S4 will come in White Frost or Black Mist colors. It is an impressive phone and one that I’m considering for my next upgrade pending good reviews. Another good consequence of the S4 launching is price reductions for the Galaxy S3, which may be an option if you don’t have impending upgrade pricing and can’t justify paying the approximate $600 full price of the S4--but still want a new Android phone.

Samsung talked up a new ARM SoC during CES that will become the new high-end part of its Exynos 5 lineup. The Samsung Exynos 5 Octa is, as the name suggests, an eight core processor. It is built on a 28nm manufacturing process and employs ARM's big.LITTLE architecture.
While Samsung is not ready to share all the detailed under-the-hood details, the Exynos 5 Octa has four Cortex A15 cores clocked at 1.8GHz paired with four Cortex A7 cores clocked at 1.2GHz. With big.LITTLE, the SoC has both high performance, high powr cores and lower power cores. The configuration is invisible to the end user, and the chip will use the Cortex A15 cores when in 3D applications or other CPU load intensive applications. Then, while the phone is idle or simply running background applications (notifications, checking email, updating twitter and facebook feeds, ect), the SoC will power down the Cortex A15 cores and use the lower power-drawing A7 cores. Ideally, this will give users a "best of both worlds" situation and a balance of performance and battery life.
Samsung claims that the Exynos 5 Octa offers up to twice the 3D performance of other existing current-generation SoCs. However, we do not yet have details on the GPU improvements (if any) over Samsung's other Exynos 5 chips much less benchmark-able products running this chip yet so it is difficult to say whether that statement is true or not. Also, Samsung claims as much as a 70% improvement in power savings over its dual core Exynos 5 processor, which is certainly a bold claim.
According to Engadget, Samsung plans to reveal all the nitty-gritty details on the eight-core Exynos 5 Octa SoC at the International Solid State Circuits Conference on February 19, 2013. It should give NVIDIA's "4+1" core Tegra 4 a run for its money, at lest on the CPU front (and maybe 3D graphics as well, but it's hard to say at this point).
