We understand some folks on T-Mobile are a little miffed about not getting the Titan and instead have to "settle" for the Radar 4G. We disagree a little bit, having handled the Radar and knowing what a svelte device it is. We also know that these second generation devices have better internal hardware, a faster CPU, newer more powerful GPU and better screens to name a few differences.
In this case, WP7.com.pl has put the HD7 next to the Radar for a side-by-side speed test. While it should be of no surprise that the Radar wins easily, it's still certainly interesting to see the margin of difference. Needless to say, a lot of us will enjoy that extra speed boost that the Radar gives, even if it still only has a 1GHz CPU (but newer build).
