Both the Motorola Xoom, ASUS Transformer and Samsung Galaxy Tab 10.1 use the same Safari browser, so a big difference wasn’t expected as all were tested with the same Wi-Fi connection. After running the benchmark five times and averaging the runs we found the Motorola Xoom to be slightly faster for web browsing out of these three tablets.
Quadrant is a CPU, I/O and 3D graphics benchmark. The Standard Edition requires an Internet connection to compute benchmark results and is supported by ads, but that should be fine for most users. We used version 1.1.7 for benchmarking the tablets.
We ran the Quadrant benchmark five times and averaged the benchmark scores to get the numbers you see in the chart above. Quadrant showed that the Samsung Galaxy Tab 10.1 did very well on this benchmark. All of the tablets tested use a screen resolutions of 1280×800, so the benchmarks we are using shouldn’t vary due to the video benchmarks. The Samsung Galaxy Tab uses Android 3.1, so that might be the difference here.
The LINPACK Benchmarks are a measure of a system’s floating point computing power. Introduced by Jack Dongarra, they measure how fast a computer solves a dense N by N system of linear equations Ax = b, which is a common task in engineering. The solution is obtained by Gaussian elimination with partial pivoting, with 2/3*N3 + 2*N2 floating point operations. The result is reported in Millions of FLoating-point Operations Per Second (MFLOP/s, sometimes simply called FLOPS). 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. We used version 1.2.8 for benchmarking the tablets.
The Samsung Galaxy Tab 10.1 did fairly well with the single-threaded test, but it was slower than the other tablets in the multi-threaded benchmark.
NenaMark is a benchmark of OpenGL ES 2.0, using programmable shaders for graphical effects such as reflections, dynamic shadows, parametric surfaces, particles and different light models to push the GPU to its limits. It can be downloaded from the Android Market or nena.se. We used NenaMark version 1.8 for benchmarking the tablets.
When it comes to this OpenGL ES 2.0 benchmark the Motorola Xoom scored 30.4 FPS and the ASUS Transformer TF101 and Samsung Galaxy Tab both scored above 42FPS. This is a fairly large performance gap for tablets that share a 1280×800 screen resolution and the same NVIDIA Tegra 2 processor.
