Intel Iris Pro Graphics 580 vs NVIDIA Quadro P5000

Intel Iris Pro Graphics 580

The Intel Iris Pro Graphics 580 (GT4e) is an integrated graphics unit of the Skylake generation (top version). As successors of the Iris Graphics 6200 (Broadwell), the Iris 580 can be found in some high-end quad core CPUs and offers 128 MB of dedicated eDRAM memory. Furthermore, the so-called GT4e-version features 72 Execution Units (EUs). Besides the eDRAM cache, the Iris 580 is able to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Compared to the Iris Graphics 550 (28 W GT3e), the Iris Pro Graphics 580 offers more EUs (72 vs. 48) and a larger eDRAM Cache (128 vs. 64 MB).

Performance

The exact performance of the Iris Graphics 580 depends on memory configuration and CPU model (different clock speeds). However, it should be clearly faster than the old Broadwell Iris Pro 6200 and may compete with a dedicated GeForce 945M. Modern games of 2015/2016 should be playable in medium settings.

Features

The revised video engine now decodes H.265/HEVC completely in hardware and thereby much more efficiently than before. Displays can be connected via DP 1.2 / eDP 1.3 (max. 3840 x 2160 @ 60 Hz), whereas HDMI is limited to the older version 1.4 (max. 3840 x 2160 @ 30 Hz). However, HDMI 2.0 can be added using a DisplayPort converter. Up to three displays can be controlled simultaneously.

Power Consumption

The Iris Graphics 580 can be found in some mobile high-end quad core processors (45 W). Therefore, they are most likely not used in thin and light laptops.

NVIDIA Quadro P5000

The Nvidia Quadro P5000 is a mobile high-end workstation graphics card for notebooks. Similar to the consumer GeForce GTX 1070 (Laptop), it is based on a slimmed-down GP104 chip with 2048 shaders. The graphics card is designed for the Kaby Lake generation and is the successor to the Quadro M5000M (Maxwell). However, the P5000 is equipped with 16 GB GDDR5 video memory (at a lower bandwidth), while GTX 1070 is limited to 8 GB. The clock rates range between 1164 MHz (base) to 1506 MHz (typical Boost) and up to 1657 MHz (max.). 

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 on par with the GTX 1070 (if the clocks did not take a massive hit), so the GPU should be significantly faster than the previous M5000M. Even the old M5500M could be beaten.

Power Consumption

The power consumption of the Quadro P5000 is similar to the old Quadro M5000M at 100 Watts TGP (max power consumption incl. memory) resp. 73.4 W TDP according to Nvidia. The card is therefore suited for large 17-inch notebooks.
