Tegra 3 vs. A5X Benchmark
 posted  March 21st 2012 at 8:49 AM

In GLBenchmark 2.1,  one of the few benchmarks that has versions for both Android and iOS, the new iPad scored higher. On the program?s Egypt Standard test, which shows a 3D animation of ancient Egypt, the new iPad and its A5X chip processed 6718 frames at a rate of 60 frames-per-second to the Transformer Primer?s 5,939 frames at 53 fps.
When GLBenchmark ran the Geometric test (vertex weighted), which measures low-level shader performance, the new iPad processed 7,530,524 frames at a rate of 57 fps while the Tegra 3-based Transformer Prime processed just 3,523,926 at a rate of 27 fps. We saw the same trend on the program?s Fill test, which measures texturing speed, as the iPad processed 1.98 billion textels per second to the Prime?s 404.61 million.

On Geekbench, a cross-platform benchmark that measures raw processing power rather than graphics, the quad-core Tegra 3 blew its competitor way as it achieved an overall score of 1,571 to the A5X?s 692. On the integer (1391 to 614), floating point (2408 to 825) and memory subtests (1076 to 784) , the Tegra 3 dominated, but the A5X bested it by a small margin of 324 to 266 on the stream subtest.

We also tested the new iPad?s Safari browser performance on two synthetic benchmarks and compared the results to those on the Transformer Prime?s stock Android browser. In Peacekeeper, a general-purpose browser benchmark, the two tablets got nearly identical scores of 386 for the iPad and 387 for the Prime. However, the iPad completed the Sunspider JavaScript rendering test in just 1810 milliseconds to the Prime?s 2216 ms.

Unfortunately, since the two tablets use two different browsers, it?s impossible to isolate the processor?s role in giving the iPad slightly faster Sunspider results. It?s quite possible that Safari just performs better on this test than the Android 4.0 browser does.
Subjective Gaming Performance

Evaluating gaming performance on any tablet is a mainly subjective task, because there?s no benchmark that measures framerates like FRAPs does in Windows. However, we attempted to see what the differences in appearance were when we played the same game on both devices and placed them side by side.
