Intel Iris Plus Graphics 650 vs NVIDIA GeForce GTX 1050 Ti (Desktop) vs NVIDIA GeForce GTX 1050 Max-Q

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 Ti (Desktop)

The Nvidia GeForce GTX 1050 Ti (N17P-G1) for desktops is an entry level gaming graphics card that was announced late 2016. It is based on the GP107 chip using the Pascal architecture and manufactured in 14nm FinFET at Samsung (the bigger Pascal chips are manufactured in 16nm at TSMC). Usually it is equipped with 4 GB GDDR5 memory with a 7 Gbps data rate. The mobile GTX 1050 Ti version should be announced later (beginning of 2017) and feature similar specs.

The performance of the GTX 1050 lies between the Radeon RX 460 and the RX 470 on a similar level of the old GeForce GTX 960 (or 970M). Therefore, the card is most suited for 1080p gaming at high detail settings (but not maximum settings).

See our extensive review of the MSI GeForce GTX 1050 Ti for more information on power consumption, benchmarks and noise level.

NVIDIA GeForce GTX 1050 Max-Q

The Nvidia GeForce GTX 1050 with Max-Q design is a mainstream GPU based on the Pascal architecture and was announced in January 2018. Contrary to the faster models, the GTX 1050 uses the GP107 chip, which is manufactured in a 14 nm process at Samsung.

The clock is not the only difference compared to the regular GTX 1050 though. The drivers for the Max-Q version were optimized for efficiency (and not performance; only for Max-Q models), there are optimized voltage converters for 1V operation, high-end cooling methods, and a 40 dB limit for the fan noise (with clock adjustments to ensure this at all times).

Features

The GP107 chip is manufactured in a 14 nm FinFET process at Samsung and offers a number of new features, including support for DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) as well as improved H.265 video de- and encoding (PlayReady 3.0). A full list of improvements and the new Pascal desktop GPUs is available in our dedicated Pascal architecture article.

Performance

The performance of the GeForce GTX 1050 Max-Q should be around 10-15 % below a regular GTX 1050 for laptops. This means the GPU is most suited for full HD gaming at high settings (not maximum).

Power Consumption

The power consumption of the GeForce GTX 1050 Max-Q is rated at 34 to 40 Watt and therefore significantly lower than the normal laptop GTX 1050 (53 Watt). Therefore, the Max-Q variant is also suited for thin and light laptops.
