NVIDIA GeForce RTX 2060 Super (Desktop) vs NVIDIA GeForce RTX 3060 Max-Q vs NVIDIA GeForce RTX 3080 Laptop GPU

The NVIDIA GeForce RTX 2060 for desktops (also known as RTX 2060S) is a fast mid range graphics card in the GeForce Turing line-up. Compared to the older GeForce RTX 2060 (that still remains in the line-up), the Super version adds 256 shaders and a wider memory bus with more memory (now 8 GB GDDR6). It is still based on the same TU106 chip (now fully utilized) and currently has no mobile counterpart (opposed to the mobile RTX 2060). The mobile RTX 2060 refresh only got slightly revised clock speeds but no new name.

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 2060S performs slightly better than the old GeForce GTX 1080 and shows a clear improvement over the older RTX 2060. Therefore, the 2060 Super is positioned in the mid range and well suited for most games of 2018 in 1080p and 1440p. Compared to AMD, the RTX 2060 Super is positioned to run against the AMD RX 5700.

Power Requirements

NVIDIA specifies that the RTX 2060 Super should consume a maximum of 175 W and therefore 15 Watt more than the RTX 2060. In our tests the power consumption of the RTX 2060S was slightly lower than the old GTX 1080.

The Nvidia GeForce RTX 3060 Max-Q (for laptops, GN20-E3, Max-Q) is the former name for a RTX 3060 Laptop GPU with Max-Q technologies. In previous generations, the Max-Q name was used for low power versions. With the RTX 3000 series, every TGP-version can now use Max-Q technologies and all GPUs are called RTX 3060 Laptop GPU (60 - 115W).

The Nvidia GeForce RTX 3080 Laptop GPU or 3080 Mobile (for laptops, GN20-E7) is the fastest graphics card for notebooks in early 2021. It is based on the GA104-775-A1 Ampere chip and offers 8 or 16 GB GDDR6 graphics memory with a 256 Bit memory bus. It supports PCIe 4.0 and will be available in different variants from 80 - 150 Watt (TGP) (80, 90, 115, 125, 135, 145 and 150+ Watt). As package the notebook graphic card uses GB5-256 and the chip size is 40x40mm. The GPU supports eDP 1.4b to connect the internal monitor.

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. At the same TGP level the RTX3080 should be faster than the old top model, the RTX 2080 Super Mobile and similar to the desktop RTX 3070. This means, the GPU should be well suited for 4k gaming or QHD with high frame rates. The similar named RTX 3080 desktop card is significantly faster.

The GA104 chip offers 6,144 FP32 ALUs of which half can also execute INT32 instructions (i.e. 3,072 INT32 ALUs). 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 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).
