The AMD Radeon Pro 455 is mobile graphics card for laptops that can be found in the high-end model of the Apple MacBook Pro Retina 15 Late 2016. It is based on the small Polaris 11 chip which is manufactured in 14 nm FinFET at Globalfoundries. Compared to the Radeon RX 460 (see for benchmarks), the Pro 455 features only 768 instead of 896 shaders and definately lower clock speeds. The peak performance is rated at 1.3 TFLOPS and therefore 30% faster than the Pro 450, but clearly slower than the 1.86 TFLOPS of the Pro 460 and 2.2 TFLOPS of the RX460. The performance of the card could be similar to the Nvidia GeForce GTX 960M as the RX 460 is similar to the GTX 965M. A major drawback is the small VRAM size of only 2 GB GDDR5. The optional Radeon Pro 460 offers 4 GB of VRAM, 1024 shaders and 1.86 TFLOPS and should be similar to the RX 460.
Apple and AMD don't provide driver updates for Windows using Bootcamp. The only option is to use modified drivers from BootcampDrivers.com.
The features of the Radeon Pro 455 are identical to the faster RX 460 and all other Polaris chips. See more details on the Polaris architecture here. According to AMD, the Pro 455 support DisplayPort 1.2 (altough 1.4 is supported by Polaris) and HDMI 2.0 (via USB-C adapter).
The power envelope of the faster Radeon Pro 460 is rated at 35 Watt according to the AMD blog post. Due to the slower specs, the Radeon Pro 455 should use slightly less.
The AMD Radeon RX 460 Notebook (or also known as mobile RX 460M) is a laptop graphics card based on the smaller Polaris 10 chip in 14 nm FinFET. It is based on the same chip as the desktop RX 460 with 896 shaders with similar clock rates (1180 versus 1200 MHz). AMD presented the card during the desktop RX 460 launch and noted that the mobile version is only slightly slower (0-7% in the presented benchmarks) than the full desktop card.
The RX460M should launch in a HP Omen laptop according to AMD and was also presented in the Asus X550IU. The desktop version of the RX 460 (XFX) was slightly faster than a refreshed 2016 GeForce GTX 965M. The mobile version should therefore perform similar to an older GTX 965M and slightly below the desktop RX 460 (see for gaming benchmarks). It should be most suited for full HD resolution and high settings (slightly reduced).
The laptop RX 460 should offer all the features of the desktop RX 460 / Polaris 10 like DisplayPort 1.4 (ready), HDMI 2.0b, HDR, H.265 improved en- and de-coding and architectural improvements (e.g. for Compute Shaders and VR).
The power consumption should be slightly lower than the desktop RX 460 which is rated at a TDP of 75 Watt for the whole card.
