NVIDIA GeForce RTX 3050 6GB Laptop GPU vs NVIDIA GeForce RTX 2070 Mobile vs NVIDIA GeForce RTX 2070 Max-Q

The Nvidia GeForce RTX 3050 6GB Laptop GPU (mobile, GN20-P0-R, 2023 Refresh) is the refresh of the RTX 3050 4GB Laptop GPU (slowest RTX 3000 mobile card) and also based on the GA107 Ampere chip. The 6GB variant offers more CUDA cores (2,560, +25%) but a cut down memory bus to 96 Bit. The clock speed depends on the TGP variant and can range from 713 - 1530 (base) and 1058 - 1740 (boost) for the TGP variants of 35 to 80 Watt (see table below).

The performance is between the old 4GB RTX 3050 and the RTX 3050 Ti and therefore best suited for full HD gaming (1920 x 1080) in medium to high graphic settings. The performance is not sufficient to enable Raytracing in most games, but the Tensor cores can be used for DLSS in some games (and get performance boost with slight quality reduction). Beware, that the low TGP variants will offer a significantly lower performance.

The GA107 chip offers 3,072 FP32 ALUs of which half can also execute INT32 instructions (i.e. 1,536 INT32 ALUs). The RTX 3050 however maybe 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 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 GA107 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).

The NVIDIA GeForce RTX 2070 for laptops is the second fastest mobile graphics card for notebooks in early 2019. It is based on the desktop RTX 2070 but with reduced core speeds (-11% Boost, -14% Base). The memory appears to be similar clocked and sized. Therefore, the RTX2070 offers 2,304 shaders and 8 GB GDDR6 memory connected by a 256 bit interface (14 GHz, 448 GB/s).

A more power efficient "Max-Q" version is also available with further reduced clock rates.

In April 2020 Nvidia refreshed the RTX 2070 with new "Super" cards. In addition to the RTX 2070 Super Mobile with 2560 shaders, Nvidia also introduced a slightly higher clocked RTX 2070 for laptops (N18E-G1R-A1, TU106-735-A1 chip) with a 1,305 base and 1,485 MHz boost clock.

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 2070 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 mobile RTX 2070 should perform a bit slower than the desktop RTX 2070 and therefore on par the old GTX 1080 for laptops. Therefore, it should be able to run all demanding games in 4k with high details. Raytracing features however may reduce framerates a lot.

The NVIDIA GeForce RTX 2070 with Max-Q design is the power saving variant of the mobile RTX 2070 graphics card with reduced clock speeds and power consumption. Therefore, it is suitable for thin gaming laptops. It is based on the same TU106 chip with 2,304 shaders and 8 GB GDDR6 memory connected by a 256 bit interface (12 GHz).

Currently it looks like there will be two variants, a low power 80 Watt variant with 885 - 1185 MHz core clock and a faster 90 Watt variant with 1080 - 1305 MHz core clock). Both clock the memory at 6 GHz versus 7 GHz of the normal RTX 2070 (115 Watt TDP).

The clock is not the only difference compared to the regular GTX 1080 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).

The Max-Q version of the RTX 2070 should perform a bit slower than the mobile RTX 2070. Therefore, it should be able to run all demanding games in 2560x1440 with maximum details. Raytracing features however may reduce framerates a lot.
