AMD Radeon Pro 460 vs AMD Radeon RX 480 (Laptop) vs AMD Radeon RX 460 (Laptop)

AMD Radeon Pro 460

The 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)

The 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 460 (Laptop)

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.
