NVIDIA Quadro P4000 vs Intel Iris Pro Graphics 580 vs Intel UHD Graphics 610

NVIDIA Quadro P4000

The Nvidia Quadro P4000 is a mobile high-end workstation graphics card for notebooks. There is currently no consumer counterpart and the GPU is sitting between the Quadro P3000 (GTX 1060) and Quadro P5000 (GTX 1070). It is equipped with 1792 shaders and should therefore use the same GP104 chip from the P5000 (2048 shaders). It has 8 GB GDDR-VRAM at the same bandwidth and has the similar 100-Watt TGP according to Nvidia.

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.

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.

Intel UHD Graphics 610

The Intel UHD Graphics 610 (GT1) is an integrated graphics unit, which can be found in low-end ULV (Ultra Low Voltage) processors of the Whisky-Lake generation. This "GT1" version of the Skylake GPU offers 12 Execution Units (EUs) clocked at up to 950 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 610 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Performance

Depending on various factors like memory configuration, the UHD Graphics 610 should offer a similar performance as the similar Intel HD Graphics 610 and the old Skylake HD Graphics 510 and therefore can only handle non demanding games. E.g. Farming Simulator 17, World of Warships or Dota 2 Reborn can be played on low settings.

Features

The revised video engine now supports H.265/HEVC Main10 profile in hardware with 10 bit colors. Furthermore, Googles VP9 codec can also be hardware decoded. The Pentium chips should already support HDCP 2.2 and therefore Netflix 4K. HDMI 2.0 however is still only supported with an external converter chip (LSPCon).

Power Consumption

The UHD Graphics 610 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.
