NVIDIA Quadro M5500 vs Intel Iris Plus Graphics 645
NVIDIA Quadro M5500
► remove from comparison
The Nvidia Quadro M5500 is a high-end, DirectX 12 (FL_12_1) and OpenGL 4.5-compatible graphics card for mobile workstations. It is a Maxwell-based GPU built on the GM204 chip with all 2048 shader cores activated and is manufactured in 28 nm at TSMC. Therefore, the GPU is similar to the consumer Nvidia GeForce GTX 980 (Notebook). Compared to the slower and less power hungry Quadro M5000M, the M5500 offers 512 more shaders which should result in 30-40% more performance according to Nvidia.
The Quadro series offers certified drivers that are optimized for stability and performance in professional applications like CAD or DCC. OpenGL performance, for example, should be significantly better compared to GeForce graphics cards of similar specifications.
Using CUDA (Compute Capability 5.2) or OpenCL 1.2, the cores of the Quadro M5000M can be used for general calculations.
The power consumption of the Quadro M5000M is rated at the same TGP of 150 Watt. Therefore, the card is suited for very large notebooks with 17-inch displays or greater.
The first laptop with the M5500 in it is the MSI WT72 Workstation.
Intel Iris Plus Graphics 645
► remove from comparison
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.
