AMD Radeon R5 (Stoney Ridge) vs Intel UHD Graphics 620

AMD Radeon R5 (Stoney Ridge)

► remove from comparison AMD Radeon R5 (Stoney Ridge)

The AMD Radeon R5 (Stoney Ridge) is an integrated graphics adapter of the weaker mobile dual-core Stoney Ridge APUs. At its launch, it is being used in the AMD A9-9410 and has 3 active Compute Cores (384 shaders). Depending on the model, the maximum clock is 800 MHz. The performance can vary heavily depending on the configured TDP and the system memory. Compared to the Radeon R5 from the Bristol Ridge series, it only has 3 instead of 6 GCN cores (and is the full configuration of the Stoney Ridge chip).

Architecture and Features

The Radeon R5 is equipped with three cores from the third GCN generation (often called GCN 1.2 or 2.0 by the press). This means it is very similar to the Tonga desktop chip and supports DirectX 12 (FL 12_0), but the graphics cores can also be accessed via Mantle, OpenGL, and OpenCL. The GPU supports the HSA 1.0 standard as well and can therefore use the connection with the CPU cores very efficiently. The technical specifications are identical to the Carrizo predecessor. 

The video unit includes the UVD 6 (Unified Video Decoder), which can decode HEVC/H.265 and 4K with support from the hardware. More details are available in our dedicated Stoney Ridge article

Power Consumption

Depending on the model and configured TDP (cTDP), the 28 nm chip is specified with 10 up to 25 Watts. This means it can also be used for thin and light notebooks.

Intel UHD Graphics 620

► remove from comparison Intel UHD Graphics 620

The Intel UHD Graphics 620 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake Refresh generation (8th generation Core). Compared to the similar named Intel HD Graphics 620 in the 2016 Kaby Lake CPUs, only the name changed from HD to UHD. It is clocked with up to 1.150 MHz and therefore 100 MHz higher than the old HD Graphics 620 (max. 1.050 MHz) and offer a comparable performance. Due to its lack of dedicated graphics memory or eDRAM cache, the HD 620 has to access the main memory (2x 64bit DDR3/DDR4).

Performance

The exact performance of the UHD Graphics 620 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model and as is similar to the Intel HD Graphics 620 and Intel HD Graphics 630. Compared to the average HD Graphics 620, the UHD graphics profits from the quad-core CPU a bit in our gaming benchmarks. Therefore, should be positioned between a GeForce 910M and 920M dedicated graphics card from Nvidia. For games, the drivers however are not that fast updated and tested as with GeForce graphics cards. In our tests, the UHD 620 is most suited for casual games like Team Fortress 2, Rocket League or Farming Simulator 17. See below for a list of modern games tested with various models.

Features

The revised video engine now supports H.265/HEVC Main10 profile in hardware with 10 bit colors. Furthermore, Googles VP9 codec can also be hardware decoded. The first models do not support HDCP 2.2 and therefore Netflix 4K. This was added with the new models in 2017 and beginning of May 2017 also the older CPU models like the i3-7100U are now shipped with a new S-Spec Code that supports HDCP 2.2. HDMI 2.0 however is still only supported with an external converter chip (LSPCon).

Power Consumption

The UHD Graphics 620 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks. The power consumption during playing The Witcher 3 (with an external monitor) was comparable to a Intel HD Graphics 620 based laptop and on the lowest end of all of our measurements. Dedicated GPUs, like the GeForce 940MX, needed a lot more power.
