Intel Iris Graphics 540 vs Intel UHD Graphics 600
Intel Iris Graphics 540
► remove from comparison
The Intel Iris Graphics 540 (GT3e) is an integrated graphics unit of the Skylake generation. As successors of the HD Graphics 6000 (Broadwell), the Iris Graphics 540 can be found in CPUs of 15-watt series and offers 64 MB of dedicated eDRAM memory. Furthermore, the so-called GT3e-version features 48 Execution Units (EUs) clocked at up to 1050 MHz (depending on the CPU model). Besides the eDRAM cache, the Iris 540 is able to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).
Compared to the Iris Graphics 550 of the 28-watt series, the Iris Graphics 540 differs only by its slightly lower maximum clock and a nearly halved TDP, which limits the utilization of the Turbo Boost in certain situations.
Performance
The exact performance of the Iris Graphics 540 depends on various factors like memory configuration (DDR3/DDR4) and maximum clock rate of the specific model. The fastest versions (Core i7-6650U) should be slightly ahead of a dedicated GeForce 920M and will handle modern games (as of 2015) in low or medium settings.
Features
The revised video engine now decodes H.265/HEVC completely in hardware and thereby much more efficiently than before. Displays can be connected via DP 1.2 / eDP 1.3 (max. 3840 x 2160 @ 60 Hz), whereas HDMI is limited to the older version 1.4a (max. 3840 x 2160 @ 30 Hz). However, HDMI 2.0 can be added using a DisplayPort converter. Up to three displays can be controlled simultaneously.
Power Consumption
The Iris Graphics 540 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.
Intel UHD Graphics 600
► remove from comparison
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.
