NVIDIA GeForce RTX 2080 Super Max-Q vs NVIDIA GeForce RTX 3070 Ti Laptop GPU vs NVIDIA GeForce RTX 2050 Mobile

The NVIDIA GeForce RTX 2080 Super with Max-Q design is the power saving variant of the mobile GeForce RTX 2080 Super with reduced clock speeds, performance and of course power consumption. It is intended for thin gaming laptops and based on the same TU104 chip with 3,072 shaders, 8 GB GDDR6 memory and a 256 Bit memory bus.

Currently it looks like there are three variants with a TGP of 80, 85 and 90 Watt. The clock speed ranges from 735 - 975 MHz for the base clock speed and 1080 - 1230 for the boost.

With the refresh, Nvidia also reworked the Max-Q technologies for more efficiency. Low Voltage GDDR6 (lower clocked but more headroom for the GPU) and improved regulator efficiency should improve the performance per Watt. Two new optional features can also be implemented by the OEM. Max-Q Dynamic Boost is able to shift power from the CPU to the GPU on a per frame basis to increase overall performance. Furthermore, the laptop manufacturer can also implement Advanced Optimus with a dynamic display switch (hardware) to enable Optimus, G-SYNC and high refresh rate displays (up to 4K 120 Hz).

Features

NVIDIA manufacturers the TU104 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 2080 Super Max-Q 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

Due to the lower clock rates, the Max-Q variant is clearly slower than the mobile RTX 2080 Super. In our benchmarks with the first devices, the performance is very similar to the old RTX 2080 Max-Q and only on a level with the non Max-Q RTX 2070. Therefore, the performance is ideal for 1440p gaming at max details for demanding games like Red Dead Redemption 2, Control or Borderlands 3. Less demanding games like F1 2019 can be played in 4k with maximum settings. Detailed gaming benchmarks can be found at the end of this page.

The power consumption of the card is between 80 - 90 Watt TGP and therefore significantly lower than the RTX 2080 Super Mobile (150 - 200 Watt).

The Nvidia GeForce RTX 3070 Ti Laptop GPU (mobile, GN20-E6, Max-P, Max-Q) is a mobile graphics card for notebooks and the refresh of the RTX 3070. It was announced early 2021 at CES and is based on the same GA104 Ampere chip as the old RTX 3070 Laptop. Compared to the old card, the newer one offers 15% more shaders but less clock speed. It will still feature the 256 Bit memory bus and 8 GB GDDR6. The RTX 3070ti is available in different power variants ranging from 80 Watt TGP with a Boost clock of 1035 MHz up to 125 Watt models with a Boost clock of 1485 MHz. However, there are even some models with a maximum TGP of 150 Watt (e.g., Acer Nitro 5).

There is no more Max-Q variant (formerly used for the low power variants) but every OEM can choose to implement Max-Q technologies (Dynamic Boost, Whispermode).

The performance depends on the TGP setting and cooling of the laptop. On average it should be somewhere between the old RTX 3070 Mobile and RTX 3080 Mobile (at similar TDP settings). Therefore, the card is best suited for QHD gaming in max details (for demanding games like Cyberpunk 2077). Less demanding games like the Farming Simulator 22 or older games should also run in 4K with max. detail settings.

The GA104 chip offers 6,144 FP32 ALUs of which half can also execute INT32 instructions (i.e. 3,072 INT32 ALUs). The RTX 3070 Ti however won't use all ALUs on the chip. With Turing all shaders could still execute FP32 or INT32 instructions. The raytracing and tensor cores on the chip were also improved according to Nvidia. The RTX 3070 Ti mobile series uses 5,888 of the 6,144 cores. The Ampere chips also include an improved 5th generation video encoder (NVENC for H.264 and H.265) and a 7th generation decoder (for various formats now including AV1).

The GA104 chip is manufactured by Samsung in 8nm (8N), which is not quite able to keep up with the 7nm node at TSMC (e.g. used by AMD and also for the professional GA100 Ampere chip).
