RIM BlackBerry Bold 9700 and Curve 8530: side by side

Introduction and Design
RIM BlackBerry Bold 9700 Release Date - November 16, 2009
RIM BlackBerry Curve 8530 Release Date - November 20, 2009


RIM has two new devices on the market, both a refresh of popular originals.  The Curve 8530 replaces the Curve 8330 on the nation’s major CDMA carriers, and the Bold 9700 is an overhaul of the 9000.  This time around the Bold is carried on both AT&T and T-Mobile, whereas the original was just available through AT&T.  Both offer minor but important refreshes to the originals; in the Curve’s case Wi-Fi has been added, and the new Bold has trimmed much of the fat off the original.  So, the Bold’s 9700 model number would indicate that it is a higher-end device than the 8530 Curve but given that both run on the same platform is there really that much of a difference?  Read on to find out!


The common thing in both of these devices is that they ditch their predecessors’ trackballs in favor of an optical track pad.  Both borrow elements of the originals’ design, but the significant slimming down of the Bold is the more drastic overhaul.  It loses significant millimeters in all dimensions and sheds half an ounce in weight.  In contrast the Curve 8530 is very similar to the original in dimensions, and actually taller than the 8330.  The new Curve does manage to slim down by a quarter of an ounce.

Both the Curve 8530 and Bold 9700 feature a 2.4” display, but the Curve only has a QVGA resolution whereas the Bold steps it up to 480x360 pixels.  Unfortunately both are only 65K colors, meaning they don’t have the color depth of devices like the iPhone or Palm Pre.  The Bold’s display has more pop to it, but both are plenty passable given that they aren’t billed as multimedia phones.

A keypad makes the BlackBerry, and the Bold is the clear winner here.  The Curve 8530 retains the smaller, hard plastic keys of the 8330 whereas the Bold 9700 has larger keys styled after the 9000’s keyboard.  The Bold is simply more comfortable to type on, leading to better accuracy.  Since the 9700 is 5mm narrower than the 9000 the keys are more cramped and not quite as good.  The Tour still remains our benchmark for QWERTY keypads.  It should also be noted that the navigation keys on the Bold are more pleasant to use due to better travel and feedback.

Both devices have lost noticeable weight from their original design, but even though the Bold lost more it is most noticeable on the Curve which now feels almost hollow.  We noted in our review that it is bordering on the line of feeling chintzy, whereas the Bold’s weight reduction was needed.  The Bold 9700 feels solid in the hand and very well-balanced.

Software and Interface:

As you would expect the interface is nearly identical as both run the BlackBerry 5.0 software.  Both of them have 256MB of internal memory, which represents a downgrade from the Bold 9000’s 1GB of onboard memory.  Both run very snappy, though the Bold feels slightly faster for one reason or another.

One noticeable difference in the two is codec support.  While the Curve supports basic formats like MPEG4, H.263 and 264 and WMV9, the Bold ups the ante with DivX and XviD support (at least partial support, anyway) which is a major upgrade for video fans.

As one would expect from a BlackBerry both devices are excellent at messaging.  The Bold’s better keyboard gives it the upper hand, but in terms of layout the two are identical.  They also offer a full-featured calendar and robust calendar support.  When connected to a BlackBerry Enterprise Server there is arguably no better business platform available.  With a nearly identical software neither device gains an upper hand here, both offer equally good amenities.

Phone Performance:

Both devices are above average in phone performance, but the Bold 9700 holds an advantage because it supports UMA calling making carrier reception less of an issue.  There was some static on the Bold at higher volumes, but the speakerphone was exceptionally clear.  The Curve 8530 had no issues to report, it is just a good sounding phone on both ends.  Battery life on the Bold is noticeably better than the Curve (6 hours of talk time versus 4.5,) which uses the same battery as the 8330 but somehow manages to get 1.5 hours less talk time out of it.


The Bold is the clear winner here, but that’s as it should be given the Curve is an 8xxx series phone and the Bold a 9xxx series.  Verizon and Sprint fans shouldn’t fret, the Tour is still a very strong competitor to this new Bold and there’s no reason to suspect the Essex (aka Tour2) won’t outdo both of them.  GSM has always gotten the head start at RIM, but CDMA usually comes out the winner in the end.
