Intel Iris Plus Graphics 645 vs Apple M2 Max 38-Core GPU vs Apple M2 10-Core GPU

Intel Iris Plus Graphics 645

► remove from comparison Intel Iris Plus Graphics 645

The Intel Iris Plus Graphics 645 (GT3e) is a processor graphics card that was first seen in the Apple MacBook Pro 13 (Entry, 2019) in mid 2019. It is similar to the Iris Plus Graphics 655 in the 28 Watt CPUs.

The so called GT3e version of the Coffee-Lake GPU still has 48 Execution Units (EUs), which can reach up to 1150 MHz depending on the model. Besides eDRAM cache, the Iris 645 can also access the system memory (2x 64 Bit DDR3L-2133/DDR4-2400) via processor interface.

Performance

The exact performance of the Iris Plus Graphics 645 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 i7-8557U. Depending on the game, the Iris Plus 655 will probably be on par with a dedicated GeForce 930M or GeForce 940MX 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 645 is used for 15-Watt processor and therefore small-sized notebooks.

Apple M2 Max 38-Core GPU

► remove from comparison Apple M2 Max 38-Core GPU

The Apple M2 Max 38-Core-GPU is an integrated graphics card by Apple offering all 38 cores in the M2 Max Chip.

The graphics card has no dedicated graphics memory but can use the fast LPDDR5-6400 unified memory with a 512 bit bus (up to 400 GBit/s).

Thanks to the additional cores and architectural improvements, the M2 Max GPU should clearly best the old M1 Max GPU with 32 cores and therefore be the fastest iGPU currently available.

The GPU is intended to use Apple Metal 2 API and could still be based on the older PowerVR architectures (last used in the Apple A10). A new feature in the MacBook Pro 14 and 16 of 2023 is the support for HDMI 2.1 and 8k output.

The Apple M2 Max is manufactured in the second generation 5nm process at TSMC. According to the internal powermetrics tool, the GPU uses up to 53.6 Watt (performance mode) and the whole chip (including the CPU) up to 89 Watt.

Apple M2 10-Core GPU

► remove from comparison Apple M2 10-Core GPU

The Apple M2 GPU is an integrated graphics card offering 10 cores designed by Apple and integrated in the Apple M2 SoC. It uses the unified memory architecture of the M2 SoC (up to 24 GB LPDDR5-6400 with 100 GB/s bandwidth) and should offer 160 execution units.

According to Apple it offers a 25% higher performance at slightly higher power consumption. The theoretical performance is rated at 3.6 Teraflops and therefore 1 TFLOP higher than the M1 8-core GPU. In our benchmarks, the GPU was able to top the M1 with up to 40%, but still stays behind the 14-core GPU in the M1 Pro. Compared to other iGPUs from AMD and Intel, the M2 benefits greatly from the unified memory architecture and the high bandwidth.

The M2 chip is manufactured in the second generation 5nm process at TSMC (most likely N5P). The power consumption is around 13.5 Watt (in our tests under load of the MBP13) and up to 15W according to Apple.
