AMD Radeon Graphics (Ryzen 7000) vs NVIDIA GeForce 920M vs AMD Radeon 610M

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.

NVIDIA GeForce 920M

The NVIDIA GeForce 920M (sometimes also NVIDIA GeForce GT 920M) is an entry level DirectX 12 graphics card. It is based on the 28 nm Kepler architecture and uses the same GK208 chip as the GeForce GT 730M, 825M and 740M. The 384 shaders are clocked at 954 MHz, while the memory (64-bit DDR3 interface) runs at 900 MHz (1800 MHz effective).

Architecture

GK208 is based on the Kepler architecture and offers two shader blocks, called SMX, each with 192 shaders for a total of 384 shader cores. The shaders are clocked at the same speed as the rest of the chip. Furthermore, the GK208 chip has 16 TMUs and 8 ROPs on a 64-bit memory interface.

PCIe 3.0 is now supported by the mobile Kepler series and GPU Boost 2.0 mode can automatically overclock the card if the laptop cooling system allows it. This feature is available on any notebook with a graphics card from the 800M series.

Performance

The GeForce 920M offers a performance similar to the AMD Radeon R7 M260 or R7 M360 and will handle modern games (as of 2014/2015) in low settings only. For comparison, a GeForce 930M is about 20 to 30 percent faster than the 920M.

Features

The feature set of the 920M corresponds to the GT 730M and 825M. This includes support for up to 4 active displays. Furthermore, high resolution monitors of up to 3840x2160 pixels can now be connected using DisplayPort 1.2 or HDMI 1.4a if available. HD-Audio codecs, such as Dolby TrueHD and DTS-HD, can be transmitted via bitstream mode through the HDMI port. However, as most laptops will feature Optimus, the integrated GPU will likely have direct control over the display ports and may limit the feature set available by the Nvidia Kepler cards.

The 5th generation PureVideo HD video processor (VP5) offers hardware decoding of HD videos. Common codecs such as MPEG-1/2, MPEG-4 ASP, H.264 and VC1/WMV9 are fully supported up to 4K resolutions while VC1 and MPEG-4 are supported up to 1080p. Two streams can be decoded in parallel for features such as Picture-in-Picture. Another feature is the inclusion of a dedicated video encoding engine similar to Intel QuickSync that can be accessed via the NVENCI API.

Power Consumption

The power consumption of the GeForce 920M is similar to the 825M and suited for 13-inch laptops and above.

AMD Radeon 610M

The AMD Radeon 610M is a pretty basic integrated graphics adapter that's found on many laptop as well as desktop AMD SoCs. It sports 2 RDNA 2 architecture CUs (128 unified shaders) running at a clock speed of up to 2.2 GHz. It can HW-decode many popular video codecs including first and foremost AVC, HEVC, VP9, AV1.

Performance

Its performance is close to what the Vega 6 and the 32 EU Iris Xe deliver. While this isn't a gaming GPU by any stretch of imagination, it actually is fast enough to run some competitive titles such as Counter-Strike 2 (~50 fps at 1080p / Low) as well as older (pre-2019) titles.

Power consumption

Considering how small the number of unified shaders and other components is here, the Radeon is unlikely to ever consume more than 10 W.
