“But if numbers are what you want, here’s what I found using the
SunSpider JavaScript benchmarks. I ran these tests on a pair of
Dell 530S desktop PCs. These older computers are powered by a
2.2GHz Intel Pentium E2200 dual-core processor with an 800MHz
front-side bus. Each has 4GB of RAM, a 500GB SATA (Serial ATA)
drive, and an Integrated Intel 3100 GMA (Graphics Media
Accelerator) chipset. One was loaded with Windows XP SP3 and the
other used MEPIS 8.0 desktop Linux. First, I ran the benchmarks
with an old copy of Chrome 4, which I installed just for these
tests, and then with Chrome 5.0.375.29, the latest beta. The
average result was 660.4ms for Chrome 4 and 380.0 for Chrome
5.”
