| Broadcom BCM970012 and BCM970015 Crystal HD card boards can be installed in the Apple TVs mini PCIe slot as a replacement for the Broadcom BCM4321 wireless card. These boards enable some software to decode H.264 video content using a dedicated hardware decoder chip instead of software decoding H.264 using the main system CPU. | Broadcom BCM970012 and BCM970015 Crystal HD card boards can be installed in the Apple TVs mini PCIe slot as a replacement for the Broadcom BCM4321 wireless card.

| - | The standard Apple TV will handle software-decoding of SD and standard profile 720p content but the 1GHz CPU chokes on higher profile 720p and all 1080p content unless you spend many (many) hours painstakingly re-encoding videos. | + | The standard Apple TV will handle software-decoding of SD and standard profile 720p content but the 1GHz CPU chokes on higher profile 720p and all 1080p content unless you spend many (many) hours painstakingly re-encoding videos. Even then the CPU is typically running at 90-100% during playback and you can expect dropped frames and stuttering during fast panning shots. With a Crystal HD decoder card installed and decoding offloaded from the system CPU the Apple TV is capable of playing all but the most challenging of 1080p content with the system CPU load peaking around 45-50%. |
