Intel Iris Plus Graphics 645 vs NVIDIA Quadro P5000 Max-Q
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.
NVIDIA Quadro P5000 Max-Q
► remove from comparison
The Nvidia Quadro P5000 Max-Q (official Nvidia Quadro P5000 with Max-Q Design) is a mobile high-end workstation graphics card for notebooks. It is the power efficient variant of the normal Quadro P5000 for laptops and offers slightly reduced clock speeds (1101 - 1366 MHz versus 1164 - 1506 MHz) and a greatly reduced power consumption (80 versus 100 Watt TGP). Similar to the consumer GeForce GTX 1070 Max-Q (Laptop), it is based on a slimmed-down GP104 chip with 2048 shaders. The graphics card is designed for the Kaby Lake generation.
The Quadro GPUs offer certified drivers, which are optimized for stability and performance in professional applications (CAD, DCC, medical, prospection, and visualizing applications). The performance in these areas is therefore much better compared to corresponding consumer GPUs.
Performance
The theoretical performance should be slightly below the normal Quadro P4000 due to the reduced clock speeds.
Power Consumption
With an TGP of 80 Watt, the P5000 Max-Q is only slightly higher rated (5 Watt) as the much slower Quadro P3000 (75 Watt) and therefore similar sized laptops can use the P5000 Max-Q.
