Intel UHD Graphics 620 vs Intel Iris Plus Graphics G4 (Ice Lake 48 EU)

Intel UHD Graphics 620

► remove Intel UHD Graphics 620

The Intel UHD Graphics 620 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake Refresh generation (8th generation Core). Compared to the similar named Intel HD Graphics 620 in the 2016 Kaby Lake CPUs, only the name changed from HD to UHD. It is clocked with up to 1.150 MHz and therefore 100 MHz higher than the old HD Graphics 620 (max. 1.050 MHz) and offer a comparable performance. Due to its lack of dedicated graphics memory or eDRAM cache, the HD 620 has to access the main memory (2x 64bit DDR3/DDR4).

Performance

The exact performance of the UHD Graphics 620 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model and as is similar to the Intel HD Graphics 620 and Intel HD Graphics 630. Compared to the average HD Graphics 620, the UHD graphics profits from the quad-core CPU a bit in our gaming benchmarks. Therefore, should be positioned between a GeForce 910M and 920M dedicated graphics card from Nvidia. For games, the drivers however are not that fast updated and tested as with GeForce graphics cards. In our tests, the UHD 620 is most suited for casual games like Team Fortress 2, Rocket League or Farming Simulator 17. See below for a list of modern games tested with various models.

Features

The revised video engine now supports H.265/HEVC Main10 profile in hardware with 10 bit colors. Furthermore, Googles VP9 codec can also be hardware decoded. The first models do not support HDCP 2.2 and therefore Netflix 4K. This was added with the new models in 2017 and beginning of May 2017 also the older CPU models like the i3-7100U are now shipped with a new S-Spec Code that supports HDCP 2.2. HDMI 2.0 however is still only supported with an external converter chip (LSPCon).

Power Consumption

The UHD Graphics 620 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks. The power consumption during playing The Witcher 3 (with an external monitor) was comparable to a Intel HD Graphics 620 based laptop and on the lowest end of all of our measurements. Dedicated GPUs, like the GeForce 940MX, needed a lot more power.

Intel Iris Plus Graphics G4 (Ice Lake 48 EU)

► remove Intel Iris Plus Graphics G4 (Ice Lake 48 EU)

The Intel Iris Plus Graphics G4(Ice Lake with 48 EUs) is an integrated graphics card in the Ice Lake SoCs (10th generation core 10xxG4) for laptops. It offers no dedicated graphics memory (no eDRAM cache like the Intel Iris Graphics 655 predecessor of the Coffee Lake SoCs). It offers 48 of the 64 EUs (Execution Units / Shader Blocks) of the Ice Lake chip and the clock rate depends on the processor model. At launch it looks like all models have a 300 MHz base clock and only differ in the boost clock (1050 - 1100 MHz). Another difference is the TDP as it can be configured from 12 - 25 Watt in the 15 Watt U-models and maybe even higher in the 25 Watt models that will come later.

The performance was not yet communicated, but due to the 25% less cores and similar clock speeds the performance should be clearly lower than the full Iris Plus G7 models. Although, the Ice Lake G4 graphics does not feature any dedicated graphics memory it should perform better than the old Iris Plus 655 with 128 MB eDRAM. Compared to AMDs offering, we suspect the performance should be similar to an AMD Radeon RX Vega 8 GPU. Therefore, the gaming performance should be only sufficient for low demanding games like Rocket League or Overwatch.

A special new feature of the Gen11 graphics card is the new Variable Rate Shading (VRS) support. With it game designers can decide where to spend shading time and e.g. shade object in the background or behind fog with less resolution (up to using only one source for a 4x4 block). With this technique early results show up to 1.3x performance in Unreal Engine POC and 1.2x speedup in Civ 6. Up to now VRS is only supported by the new Nvidia Turing architecture (GTX 1650 and up).

Another improved hardware piece is the integrated video de- and encoder that was improved significantly according to Intel. They did not specify any more details, but the previous generation was able to decode VP9 and H.265/HEVC in Main10 profile with 10 bit color depth using the dedicated hardware.

The Iris Plus G4 supports three display pipes that can each output 5K60 signals (via DisplayPort 1.4 HBR3 or HDMI 2.0b). Combining two pipes, the chip is capable to output 8k content.

The Ice Lake SoCs and therefore the integrated GPU are manufactured in the modern 10nm+ process at Intel that should be comparable to the 7nm process of TSMC.
