Samsung Infuse 4G Android Smartphone Review

Performance: General CPU and Graphics Tests

In addition to working with the Samsung Infuse 4G in a variety of everyday usage scenarios, we also conducted some formal performance benchmark testing to see how well the device compares to other smartphones.

The LINPACK Benchmarks are a measure of a system’s floating point computing power.  However, This test is more a reflection of the state of the Android Dalvik Virtual Machine than of the floating point performance of the underlying processor. Software written for an Android device is written using Java code that the Dalvik VM interprets at run time...

Here, the Samsung Infuse 4G clocks in with midland performance, in the general vicinity of other sibling Samsung smartphones. However, with its 1.2GHz version of the Humminbird processor, it manages to out-pace other Samsung devices by about 23% or so, in keeping with its 20% clock speed bump.  However, the Infuse 4G trails Qualcomm Snapdragon-based devices like the HTC Thunderbolt, by a very wide margin in this test.

An3DBench is a benchmarking tool based on an Android port of the jPCT 3D engine.  The app runs 7 tests in total that look at graphics processor fill rate and complex rendering workloads and scenes.  We also were able to run some tests with An3DBenchXL, which is a newer version of the app that is significantly more demanding.

With its PowerVR SGX540 graphics core, the Samsung Hummingbird processor in the Infuse 4G offers significantly better graphics performance versus Qualcomm Snapdragon-based devices, like the HTC Thunderbolt, this time around.  As you can see in the first version of the test, both the Infuse 4G and the Droid Charge (both based on Samsung's Hummingbird CPU), offer best of class performance.  We're still gathering data for the latest version of An3DBench XL but in this test, you can see that the 1.2GHz Hummingbird performs well versus other handsets but can't keep up with the dual-core 1GHz NVIDIA Tegra 2 chip in the Asus, ViewSonic and Motorola tablets we've included here for reference.  Regardless, especially for its size and weight, the Infuse 4G offers excellent multimedia performance.

Sunspider calculates Javascript performance, an important metric in terms of understanding a smartphone's potential performance and responsiveness in web browsing.  Here, though it can't quite catch the Kyocera Echo, the Samsung Infuse 4G handily out-paces many other high-end 4G smartphones in its class.
