We are now starting to see players being released with the latest consumer Sigma chipset, the Sigma 867x (at the moment the 8670 and 8671). The first players are from long time Sigma chipset supporters, Popcorn Hour and HDI Dune:
Popcorn Hour V8
Dune TV-301
Dune TV-101
I would expect more players to follow before Christmas. Most interesting will be whether a new WDTV is released. Western Digital have always released players very near the beginning of each Sigma chipset generation, WDTV1 for Sigma 8635 and WDTV2 for Sigma 8655. I would expect a WDTV3 featuring Sigma 8670 to be imminent. Unfortunately we are unlikely to get any prior notice. The WDTV2 launch came entirely unexpected and this is how the WDTV3 is likely to appear. If you’re in the United States keep your eyes peeled for a new WDTV on the shelves of Best Buy!
The Sigma 8670 offers an incremental improvement on the 8655, but nothing spectacular. The most valid comparison is with the Realtek 1185, also released this year and having many similar specifications.
Both 8670 and 1185 feature near total format support, full 7.1 audio, USB 3.0 slave.
Where the 8670 is better: Faster clock speed (700 vs 500Mhz).
Where the 1185 is better: BD Profile 1.0, Gigabit LAN.
These differences are in fact very nominal. The faster clock speed is likely to make no difference to player operation, with both chipsets more than capable of playing practically everything. BD Profile 1.0 is nice to have but most discs are Profile 2.0 nowadays. We are yet to test the network transfer speed of the 8670 but the Gigabit LAN in 1185 players is constrained by the speed at which the chipset can process incoming data, so the actual speeds achieved are likely to be similar across the two chipsets.
The biggest difference is likely to be in the firmware. Realtek have always released a near complete base firmware (e.g. ‘Casablanca’) with their chipsets. This allows hardware makers to launch products with minimal resources put into software development. Sigma are very different in their approach, with nothing like as complete a base firmware, meaning that significant resources are needed to released a player with decent software.
Both approaches have their merits, but the practical result is that Realtek players are cheaper but tend to all have similar firmware. Only the larger companies have the resources to develop their own firmware for the Sigma chipset and have to do so from near scratch. So Sigma players have much greater variety, with more varied software features, but you are much more reliant on software development from the end brand whereas Realtek players all get key base firmware updates direct from Realtek.
