Intel Iris Plus Graphics 650 vs Intel UHD Graphics (Jasper Lake 16 EU) vs Intel HD Graphics 620

Intel Iris Plus Graphics 650

The Intel Iris Plus Graphics 650 (GT3e) is a processor graphics card for Kaby Lake models announced in January 2017. As the successor to the Intel Iris Graphics 550 (Skylake), the Iris Plus Graphics 650 is used for 28-Watt models and is equipped with 64 MB eDRAM cache. There should not be any big changes compared to the Iris Graphics 550.

The so called GT3e version of the Kaby Lake GPU probably still has 48 Execution Units (EUs), which can reach up to 1100 MHz depending on the model. Besides eDRAM cache, the Iris 650 can also access the system memory (2x 64 Bit DDR3L-1600/DDR4-2400) via processor interface.

Compared to the Iris Plus 640 from the 15-Watt models, the Iris 650 only has a slightly higher maximum clock as well as almost twice the TDP, which allows a better utilization of the Turbo Boost potential.

Performance

The exact performance of the Iris Plus Graphics 650 depends on the CPU model, because maximum clock as well as the size of the L3 cache can differ a bit. The system memory (DDR3/DDR4) will influence the performance as well.

The fastest chips are high-clocked Core i7 models like the Core i7-7567U. Depending on the game, the Iris Plus 650 will probably be on par with a dedicated GeForce 930M and can handle smooth gameplay in modern titles in low up to medium settings.

Features

The reworked video engine now fully supports hardware decoding of H.265/HEVC videos. Contrary to Skylake, however, Kaby Lake can now also decode H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The video output is possible via DP 1.2/eDP 1.3 (up to 3840 x 2160 @60 Hz), whereas HDMI is also supported in the older 1.4a standard. An HDMI 2.0 output can be added via converter from DisplayPort. The GPU can drive up to three displays simultaneously.

Power Consumption

The Iris Plus Graphics 650 is used for 28-Watt processor and therefore medium-sized notebooks.

Intel UHD Graphics (Jasper Lake 16 EU)

► remove from comparison

The Intel UHD Graphics 16 EUs (Jasper Lake, Gen. 11) is an integrated graphics card in the Jasper Lake Celeron SoCs for laptops and small desktops. It is the low end GPU version in the Jasper Lake series (Celeron Dual-Cores) and offers only 16 of the 32 EUs (Execution Units / Shader Blocks). It offers no dedicated graphics memory and the clock rate depends on the processor model. At launch there are two Celeron models (N4500 with 6W and N4505 with 10W) clocked at 350 - 750 MHz.

Thanks to the improved architecture and more EUs, the UHD Graphics is clearly faster than the old Gemini Lake SoCs (e.g. UHD Graphics 600).

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 Jasper Lake SoCs and therefore the integrated GPU are manufactured in the 10nm process (like Ice Lake probably) at Intel that should be comparable to the 7nm process of TSMC.

Intel HD Graphics 620

► remove from comparison

The Intel HD Graphics 620 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake generation. This "GT2" version of the Kaby Lake GPU is clocked at up to 1050 MHz (depending on the CPU model). 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 HD Graphics 620 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model but is very similar to the old HD Graphics 520 GPU. That means only some less demanding recent games like Farming Simulator 17 run fluently in low detail settings (see below for gaming benchmarks). Compared to dedicated graphics cards, the HD620 should be positioned between a GeForce 910M and 920M from Nvidia. For games, the drivers however are not that fast updated and tested as with GeForce graphics cards.

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 HD Graphics 620 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.
