The AMD Radeon R9 M470X is an upper mainstream mobile graphics card based on the familiar Bonaire chip. This 28 nm GPU uses all 896 shaders (14 Compute Units CU) and is based on the second generation of the GCN architecture (Graphics Core Next). The maximum memory size is 4 GB (GDDR5, 6000 MHz effective) and it is attached via 128-bit interface. Compared to the technologically identical predecessor card Radeon R9 M385X (1100 MHz), the R9 M470X could have a slightly higher clock.
Contrary to the R9 M300 series, the number of products within the R9 M400 series is currently limited to three (M485X, M470X and M470), but this will probably change with the launch of the new Polaris architecture in Q2 2016.
The Intel UHD Graphics 600 is an integrated processor graphics unit from the Gemini Lake generation (e. g. Pentium N4100), which was announced late 2017. The GPU can convince with low consumption figures, but the performance is only in the low-end segment and is rarely sufficient for modern games. Being the lowest configuration of the Gemini Lake GPU, the UHD Graphics 600 is equipped with 12 of the 18 Execution Units (EUs) running at up to 700 MHz. The technical specifications of the GPU are based on Intel's Gen9 architecture, which is also used for the more expensive Skylake series and also in the predecessor HD Graphics 505.
Due to its lack of dedicated graphics memory or eDRAM cache, the UHD 605 has to access the main memory via processor (2x 64bit DDR4/LPDDR4-2400).
Performance
The UHD Graphics 600 offers a similar performance as the Intel HD Graphics 500 in the Apollo Lake SoCs (same Gen 9 architecture). Therefore, the GPU is only suited for some very low demanding games like Dirt Rally or Sims 4.
Features
The video engine decodes H.265/HEVC (8b and 10b) and VP9 completely in hardware. Up to three displays can be connected via DP 1.2a/eDP 1.3 or HDMI 2.0a (including HDCP 2.2).
Power Consumption
The TDP of the whole Pentium N4100 chip is 6 Watts by default, so the GPU is primarily used for (often passively cooled) netbooks or thin notebooks. The TDP can also be reduced to 4.8 Watts, but this will obviously affect the performance.
The AMD Radeon R9 M485X is a mobile graphics card based on the familiar Tonga chip. The R9 M485X uses all 2048 shaders (32 Compute Units CU) and is based on the third generation of the GCN architecture (Graphics Core Next). Similar to the predecessor cards R9 M395X and M295X, the power consumption should be between 100 and 125 Watts. Compared to the technologically identical Radeon R9 M395X (909 MHz Boost; optional upgrade for the 2015 iMac), the Radeon R9 M485X could have a slightly higher clock. It is the only model from the series (M485X, M470X and M470) with up to 8 GB GDDR5 RAM and a 256-bit memory interface.
Contrary to the R9 M300 series, the number of products within the R9 M400 series is currently limited to three (M485X, M470X and M470), but this will probably change with the launch of the new Polaris architecture in Q2 2016.
Our gaming benchmarks with the iMac show the predecessor GPU M395X roughly on par with a GeForce GTX 880M or GTX 970M (see below), respectively. Still, the performance is definitely not sufficient for demanding titles in 5K, and this will most likely not change with the M485X.
