Intel Iris Plus Graphics 650 vs NVIDIA GeForce GTX 1050 (Desktop)

Intel Iris Plus Graphics 650

The Intel Iris Plus Graphics 650 (GT3e) is a processor graphics card for Kaby Lake models announced in January 2017. As the successor to the Intel Iris Graphics 550 (Skylake), the Iris Plus Graphics 650 is used for 28-Watt models and is equipped with 64 MB eDRAM cache. There should not be any big changes compared to the Iris Graphics 550.

The so called GT3e version of the Kaby Lake GPU probably still has 48 Execution Units (EUs), which can reach up to 1100 MHz depending on the model. Besides eDRAM cache, the Iris 650 can also access the system memory (2x 64 Bit DDR3L-1600/DDR4-2400) via processor interface.

Compared to the Iris Plus 640 from the 15-Watt models, the Iris 650 only has a slightly higher maximum clock as well as almost twice the TDP, which allows a better utilization of the Turbo Boost potential.

Performance

The exact performance of the Iris Plus Graphics 650 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 i7-7567U. Depending on the game, the Iris Plus 650 will probably be on par with a dedicated GeForce 930M 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 650 is used for 28-Watt processor and therefore medium-sized notebooks.

NVIDIA GeForce GTX 1050 (Desktop)

The Nvidia GeForce GTX 1050 is an entry level graphics card for desktops based on the Pascal architecture. It uses the same GP107 chip as the GTX 1050 Ti, but with only 640 instead of 768 shaders. The chip is manufactured at Samsung in 14 nm (opposed to the 16 nm TSCM based Pascal chips of the 1060 and up). The performance and specs should be similar to the GTX 1050 laptop version, that will be released later (early 2017). Compared to the faster GTX 1050 Ti, the 1050 offers less shaders (640 instead of 768) and only 2 GB of GDDR5 (instead of the 4 GB of the 1050 Ti).

Gaming benchmarks by Nvidia state that the GTX 1050 is about 30% faster on average than the Radeon RX 460 with 2 GB VRAM. The 4 GB version of the RX 460 should be about 10% slower and the older GTX 950 should reach a similar performance level as the new GTX 1050. Therefore, the GTX 1050 should be ideal for 1080p gaming with high detail settings (but not max settings).
