AMD Radeon RX 490M vs AMD Radeon RX 480 (Laptop) vs AMD Radeon RX 460 (Laptop)
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.
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 460 (Laptop)
► remove from comparisonThe 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.
