In the "about this" section for the HTC Sensation, Vodafone compared the superphone to the Desire HD and, unsurprisingly, the latest flagship handset from HTC came out on top in the comparison each time.
That said, if there's one area where the HTC Desire HD has the upper hand, it's when it comes to pricing. Although the price of the HTC Sensation is still unknown, it is unlikely to be under £500, the same price as the Samsung Galaxy S II, its closest competitor.
The HTC Desire HD can be purchased from Affordable Mobiles from £368 (an 18 month contract with unlimited internet, 100 minutes, 100 texts at £20.42 per month).
Both the HTC Desire HD and the Sensation have a 4.3-inch screen, the former with a WVGA resolution and the newer with a qHD display.
They share the same eight megapixel rear camera with dual flash and AF; in addition, the Sensation has a front facing VGA camera
The Sensation is not as wide and is thinner than the Desire HD but is a tad longer. It is a clear winner when it comes to weight being 10 per cent lighter than its predecessor.
Both handsets have 768MB onboard memory but the HTC Desire HD has 1.5GB internal storage while the Sensation has only 1GB. When it comes to processing power, the Sensation has a dual core MSM8260 system on chip clocked at 1.2GHz with an Adreno 220 GPU.
In comparison, the Desire HD has a rather unexceptional MSM8255 which is a single core model clocked at 1GHz with an Adreno 205 GPU.
Interestingly, the same SoC is used in the four newest Sony Ericsson smartphones AND in the two other new HTC handsets, the Incredible S and the Desire S.
As for the battery, the Sensation has a much better battery at 1520mAh, up from the Desire HD's 1230mAh. Curiously, HTC quotes the same talk time on GSM and significantly worse standby time for GSM and WCDMA.
Software wise, both handsets will run on Android Gingerbread in due time although the Sensation will have a head start.
