NVIDIA GeForce RTX 4070 vs AMD Radeon Graphics (Ryzen 7000) vs AMD Radeon 680M

NVIDIA GeForce RTX 4070

The Nvidia GeForce RTX 4070 is a high-end desktop graphics card based on the AD104 chip using the Ada Lovelace architecture. The 4070 offers 5,888 cores and 12 GB GDDR6X graphics memory with a 192 bit memory bus and clocked at 21 Gbits. The card offers a good raytracing performance thanks to the 46 dedicated raytracing cores. For AI calculations (and DLSS 3 in games), the RTX 4070 has 184 Tensor cores.

The gaming performance is well suited for 2k/QHD gaming in most demanding games, and should be able to handle 4k gaming for lesser demanding games (or with reduced settings / DLSS activated). The raw gaming performance is comparable to an older RTX 3080 or a AMD Radeon 6800 XT. Compared to the similar named mobile GeForce RTX 4070 Laptop GPU, the desktop variant is much faster.

The AD104 chip is manufactured in the modern 5nm process at TSMC (4N with EUV) and specified with a TGP (Total Graphics Power) of 200 Watt (compared to the 450 Watt of the RTX 4090).

AMD Radeon Graphics (Ryzen 7000)

The AMD Radeon Graphics of the Ryzen 7000 desktop CPUs is an integrated graphics card (iGPU) based on the RDNA 2 architecture. It offers only 2 CUs (128 shader) and is similar to the Radeon 610M. The clock speed in most CPUs ranges between 400 to 2200 MHz. Due to the low amount of shaders, the gaming performance is very low and only suited for low demanding games. The GPU also integrates an AMD Video Coding Engine (VCE) for H.264, H.265 10/8bpc encoding and AV1, VP9, H.265, and H.264 10/8bpc decoding.

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.
