NVIDIA GeForce RTX 2060 (Desktop) vs Intel Iris Plus Graphics 645

The NVIDIA GeForce RTX 2060 for desktops is a fast mid range graphics card in the GeForce Turing line-up. It uses a TU106 chip with 1,920 shader, 45 ROPs, 120 TMUs, 240 KI-cores and a 192 Bit memory bus that connects 6 GB of GDDR6 (clocked at 7 GHz leading to 14 GHz effective and 336 GB/s).

 The mobile variant of the RTX 2060 bears the same name, but offers considerable lower clock speeds (see our RTX 2060 laptop page).

Features

NVIDIA manufacturers the TU106 chip on a 12 nm FinFET process and includes features like Deep Learning Super Sampling (DLSS) and Real-Time Ray Tracing (RTRT), which should combine to create more realistic lighting effects than older GPUs based on the company's Pascal architecture (if the games supports it). The RTX 2060 is also DisplayPort 1.4 ready, while there is also support for HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) and H.265 video en/decoding (PlayReady 3.0).

Performance

The average RTX 2060 should be on par with a Radeon RX Vega 64 and between the GeForce GTX 1070 and GTX 1080 / 1070 Ti. Therefore, the RTX 2060 is most suited for 1920x1080 to 2560x1440 in demanding games.

Power Requirements

NVIDIA specifies that the RTX 2060 should consume a maximum of 160 W and therefore clearly higher than the old GTX 1060 rated at 120 Watt.

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.
