NVIDIA GeForce GTX 1070 Max-Q vs AMD Radeon RX 6600M vs AMD Radeon RX 6650M XT

NVIDIA GeForce GTX 1070 Max-Q

The Nvidia GeForce GTX 1070 with the Max-Q design is a mobile high-end GPU from the Pascal series. It is designed for thin and light laptops and about 10-15% slower than a regular GTX 1070 for laptops based on the cooling capabilities. The base frequency (1101-1215 MHz) is also much lower than on the regular GTX 1070 (1433 MHz, at least -10%) and the Boost (1265-1379 MHz) is also much lower compared to 1645 MHz (at least -6%) for the regular GTX 1070. The memory clock, however, is identical.

The clock is not the only difference compared to the regular GTX 1070 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 GP104 chip is manufactured in 16nm FinFET process at TSMC and offers a range of new features. DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP), improved H.265 video en- and decoders (for PlayReady 3.0) are only some of the improvements. See our detailed Pascal architecture article for more details.

The power consumption of the Max-Q design is notably lower than the normal GTX 1070 for laptops and ranges between 80 and 90 Watt (TGP) according to Nvidia.

AMD Radeon RX 6600M

The AMD Radeon RX 6600M is a mobile mid-range graphics card based on the Navi 23 chip (RDNA 2  architecture) manufactured in the modern 7nm process. It features 1,792 cores (28 CUs - compute units) and 8 GB of fast GDDR6 graphics memory connected with a 128 Bit memory bus. The chip also includes 32 MB Infinity Cache. The clock speed of the cores will depend on the laptop according to AMD. The power consumption (TDP settings) ranges from 50 - 100 Watt with different clock speeds (similar to Nvidia).

At 100 Watt the game clock reaches 2177 MHz (max boost 2416 MHz) and the performance should be similar to a RTX 3060 for laptops. When Raytracing effects are activated, it falls behind the GeForce GPUs.

AMD Radeon RX 6650M XT

The AMD Radeon RX 6650M XT is a mobile mid-range graphics card based on the Navi 23 chip (RDNA 2  architecture) manufactured in 7nm. It features 2,048 cores (32 CUs - compute units) and 8 GB of fast GDDR6 graphics memory connected with a 128 Bit memory bus. The chip also includes 32 MB Infinity Cache. The clock speed of the cores will depend on the laptop according to AMD. The specified game clock speed is 2162 MHz (most likely at 120 W TGP). 

AMD compares the performance to the RTX 3060 for laptops and similar to the RX 6600M. When Raytracing effects are activated, it falls behind the GeForce GPUs. Compared to the normal RX 6650M, the XT variant offers more shader, but at a slower clock speed.
