AMD Radeon RX 470 (Laptop) vs AMD Radeon RX 480 (Desktop) vs AMD Radeon RX 460 (Desktop)
AMD Radeon RX 470 (Laptop)
► remove from comparisonThe AMD Radeon RX 470 for laptops (RX 470M) is a mid-range graphics card for laptops. It was announced in August 2016 and is based on the Polaris 10 chip, just like its bigger sibling Radeon RX 480. The GPU does, however, only use 2048 shader units (32 CUs, 128 TMUs) from 2304 (36 CUs, 144 TMUs). The clock speeds look to be similar to the desktop version of the RX 470 (at least in the Alienware 17, see GPU-Z screenshot). Therefore, the performance should be on par with a non overclocked desktop version.
The performance is similar to a desktop GeForce GTX 970 and a bit slower than the newer GeForce GTX 1060 (mobile) and should be faster than the previous top model M395X. Modern games from 2016 can usually be played in the Full-HD resolution and the highest settings.
The TDP of the desktop Radeon RX 470 is specified with 120 Watts by AMD, the mobile version should be a bit more power efficient due to selected chips.
AMD Radeon RX 480 (Desktop)

► remove from comparisonThe AMD Radeon RX 460 is an entry-level gaming graphics card for desktop PCs. It was announced it August 2016 and is based on the smaller Polaris 11 chip (123 mm²), which is manufactured in a 14 nm FinFET process. The GPUs RX 470 and RX 480 on the other hand are based on the bigger Polaris 10 chip (232 mm²). The RX 460 uses 14 out of 16 Compute Units, all 16 ROPs, 56 TMUs, four 32-bit memory controller and 1 MB L2-cache. AMD specifies the clock with 1080 (base) up to 1200 MHz (Boost), but custom cards can have slightly higher clocks (like our test card from XFX at 1220 MHz). Contrary to Polaris 10, Polaris 11 supports Power Gating between the individual Compute Units. This will result in a lower consumption with partial workloads in particular.
Depending on the memory equipment (2 or 4 GB GDDR5), the gaming performance of the RX 460 can differ quite a bit. Memory intensive games like Doom, Black Ops 3 or Mirror's Edge clearly suffer from just 2 GB. The 4 GB model is slightly faster than the mobile GeForce GTX 965M (refresh) as well as the desktop MSI Radeon R7 370 in our tests. This means the card is best suited for modern games in Full-HD at high details. The RX 460 is particularly convincing in DirectX 12 and Vulkan games.
Polaris 11 is up to date in terms of features. It supports DirectX 12, Vulkan, DisplayPort 1.3 HBR (1.4 Ready), HDMI 2.0, FreeSync, HDR, and H.265 de- and encoding.
Thanks to the 14 nm FinFET process, the power consumption was significantly reduced compared to a similarly fast R7 370. The RX 460 is also much more frugal compared to the RX 470 and 480 and only needs a bit more power than the expensive GTX 1070 Founders Edition while idling. It is also much more frugal than the old R7 370 and roughly on par with the Maxwell chips (GTX 950 - 960) under load.
