AMD Radeon Pro 560X vs AMD Radeon RX 480 (Laptop) vs AMD Radeon Pro 455
AMD Radeon Pro 560X
► remove from comparisonThe AMD Radeon Pro 560X is a mobile graphics card based on the small Polaris 21 chip from AMD. It is an option for the 15-inch Apple MacBook Pro 2018 and is very similar to the Radeon Pro 460. Compared to the Radeon Pro 560 from the 2017 MBP15, the 560X is slightly higher clocked. The Radeon Pro 555X from the entry level model offers less cores.
The mobile Radeon Pro 560X should support all features of the desktop RX 460/560 like DisplayPort 1.2 (Polaris actually supports up to 1.4), HDMI 2.0 (via USB-C adapter), new H.265 video de- and encoder as well as architectural improvements. More information about the Polaris architecture is available in our dedicated review.
The Polaris 21 chip is manufactured in a slightly improved 14nm FinFET process according to AMD. The power consumption of the Radeon Pro 460 is 35 Watts according to AMD, so this should also be the case for the Pro 560X.
AMD Radeon RX 480 (Laptop)
► remove from comparisonThe AMD Radeon RX 480 (formerly known as R9 M480 or RX 480M) is a mobile high end graphics cards. It is based on the new Polaris architecture (Polaris 10 chip) and manufactured in 14nm FinFET. It should be based on the same chip as the desktop RX 480 (see for benchmarks and specs) but maybe offer lower clock speeds. The card was never used in a laptop (up to now) and succeeded by the slightly improved Radeon RX 580.
AMD Radeon Pro 455
► remove from comparisonThe 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.
