Intel Iris Plus Graphics 650 vs Qualcomm Adreno 690 vs Qualcomm Adreno 660

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.

Qualcomm Adreno 690

The Qualcomm Adreno 690 is an integrated graphics card in the Qualcomm Snapdragon 8cx Gen 3 SoC for Windows laptops. According to Qualcomm, the 690 is up to 60% faster than the previous generation. In our tests with the Lenovo ThinkPad X13s, the Adreno 690 was only on par with a low en Intel UHD Graphics iGPU and not well suited for 3D games.

The chip is manufactured in 5nm at Samsung (5LPE) and suited for fanless laptops.

Qualcomm Adreno 660

The Qualcomm Adreno 660 is a smartphone and tablet GPU that is integrated within the Qualcomm Snapdragon 888 SoC. The chip will be available from early 2020 and will be used mainly in high-end Android devices.

According to Qualcomm, the Adreno 660 GPU offers a 35% improved performance over the Adreno 650, its predecessor, which is integrated into the Snapdragon 865 SoC. Qualcomm also states that the energy efficiency improved by 20% which might be due to the new 5nm process at Samsung where the chip is produced.

The Adreno 650 supports Vulkan 1.1, DirectX 12, OpenGL ES 3.2, and OpenCL 2.0 FP. Furthermore, games and videos can use HDR10+ and Dolby Vision (with a supported display).
