Sunspider JavaScript Benchmark on 4 models of Microsoft Surface

Today I got my first sight of Microsoft’s new models of Surface, its Windows tablet, on display at the Microsoft Store in Bellevue.

I ran the Sunspider JavaScript benchmark on the new models, and then on the old ones for comparison.

  • Surface RT 1.0: 922ms
  • Surface 2.0 (RT): 397ms
  • Surface Pro: 127ms
  • Surface Pro 2.: 114ms

No surprises; but what this confirms is that Surface 2.0 RT, which has an NVIDIA Tegra 4 chipset, is substantially faster than the earlier Tegra 3 model; whereas Surface Pro which has an updated Intel Core i5 processor is only a little faster on this particular test.

Microsoft is attempting to continue selling Surface RT alongside Surface 2.0 RT, at $349 vs $449 for the 32GB model. However the new one is a better buy and I imagine the price of the earlier model will fall further, given that Microsoft appears still to have substantial stocks.
