AMD Radeon Pro 460 vs AMD Radeon RX 480 (Laptop) vs AMD Radeon RX 490M
AMD Radeon Pro 460
► remove from comparisonThe AMD Radeon Pro 460 is mobile graphics card for laptops that can be ordered as an option for the Apple MacBook Pro 15 Late 2016. It is based on the small Polaris 11 chip which is manufactured in 14 nm FinFET at Globalfoundries. Compared to the similar Radeon RX 460 (see for benchmarks), the Pro 460 offers all 1024 shaders of the Polaris 11 chip but most likely at a reduced clock speed. AMD states a peak performance of 1.86 TFLOPS, compared to the 2.2 of the RX 460 (desktop). Apple presented the Pro 460 as 130 % faster than the previous Radeon R9 M370X in the 2015 MacBook Pro 15 regarding graphics performance.
The performance should be therefore a bit slower than the Radeon RX 460, which is similar to the GTX 965M. It is the only card in the MacBook Pro 15 line-up that features more than 2 GB VRAM (Radeon Pro 450 and 455). Furthermore, 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 460 are identical to the faster RX 460 and all other Polaris chips. See more details on the Polaris architecture here. Therefore, the Pro 460 should support DisplayPort 1.2 (although Polaris supports up to 1.4 ready) and HDMI 2.0 (via USB-C adapter) as well as H.265 video de- and encoding (support in macOS questionable).
The power consumption of the Pro 460 is rated at a TDP of 35 Watt (according to the AMD blog post).
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 RX 490M
► remove from comparisonThe AMD Radeon RX 490M (formerly known as R9 M490) is a mobile high end graphics cards. It should be based on the new Polaris architecture and manufactured in 14nm FinFET. Up to now it only surfaced in a driver (according to Videocardz.com) and should be announced in mid 2016. The efficiency of Polaris should be greatly improved and therefore the M490 should at least be able to perform like a GeForce GTX 980M.
