AMD Radeon 680M vs NVIDIA GeForce RTX 3060 Ti vs NVIDIA GeForce RTX 3090

AMD Radeon 680M

The AMD Radeon 680M is an integrated GPU in the Ryzen 6000 series for laptops (Rembrandt, e.g. Ryzen 9 6980HX). The iGPU is based on the RDNA2 architecture and has 12 CUs (= 768 shaders) clocked at up to 2,400 MHz (depending on the CPU model). The 680M and 660M iGPUs are the first integrated graphics card with hardware raytracing support, although the performance is too slow to use it in current games.

Thanks to the new architecture, high core count and the increased maximum core clock, the Radeon 680M should be clearly faster then the old Radeon Vega 8 iGPUs. Therefore, the 680M should be the fastest integrated graphics card in early 2022. Compared to the dedicated Radeon 5300M (also RDNA), the 680M should still be significantly slower. According to AMD, the Radeon 680M (in the 6800U) is faster than a dedicated Nvidia GeForce MX450 and best suited for 1080p gaming and low details (for AAA games).

Thanks to the modern 6nm process and clever power-saving features, the power consumption is comparatively low (according to AMD), so the graphics card can also be used for slim and light notebooks (depending on the CPU model). The whole Ryzen 6000 chip can be configured down to 15W.

NVIDIA GeForce RTX 3060 Ti

The Nvidia GeForce RTX 3060 Ti is a fast desktop graphics card based on the Ampere architecture. It uses the big GA104 chip and offers 4,864 cores and 8 GB GDDR6 graphics memory. 

The performance in games and 4k resolution is slightly above a desktop RTX 2080 Super. For many games, the performance is sufficient for 4k and maximum details. Enabling raytracing however (without DLSS) will lead to a significant lower performance (although the RTX performance was clearly improved compared to the RTX 2000 series).

The GA104 chip is produced in 8nm at Samsung and the power consumption of the RTX 3060 Ti is specified with 200 Watt (RTX 2070 Super - 215 Watt).

NVIDIA GeForce RTX 3090

The Nvidia GeForce RTX 3090 is high-end desktop graphics card based on the Ampere generation. It uses the big GA102 chip and offers 10,496 shaders and 24 GB GDDR6X graphics memory. Compared to the slower RTX 3080, the 3090 offers 10 - 20% higher gaming performance, but only above 4k. Still it has not enough power for 8k gaming at maximum detail settings. The RTX3090 is rated at 350 Watt but the power efficiency is still quite good.
