AMD Radeon HD 8280 vs Intel HD Graphics 620

AMD Radeon HD 8280

The AMD Radeon HD 8280 is an integrated DirectX 11.1 graphics card typically paired with AMD Kabini-class APUs (for example, E2-3000). It offers 128 shader cores and two Compute Units based on the GCN architecture and is clocked at 450 MHz with no support for Turbo. The graphics card does not have dedicated VRAM and will access the main memory of the system (up to single-channel DDR3L-1600).

The HD 8280 integrates both UVD 4.2 and VCE 2.0 video encoders. It supports up to two external monitors via VGA, DVI, HDMI 1.4a and DisplayPort 1.2.

Depending on the benchmark, the performance of the Radeon HD 8280 is slightly below the Intel HD Graphics (Haswell). This is on par with a dedicated Radeon HD 7370M, but is still too slow for most demanding games as of 2013. However, some older and less demanding games should run fluently if the performance of the CPU is sufficient.

Intel HD Graphics 620

The Intel HD Graphics 620 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake generation. This "GT2" version of the Kaby Lake GPU is clocked at up to 1050 MHz (depending on the CPU model). 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 HD Graphics 620 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model but is very similar to the old HD Graphics 520 GPU. That means only some less demanding recent games like Farming Simulator 17 run fluently in low detail settings (see below for gaming benchmarks). Compared to dedicated graphics cards, the HD620 should be positioned between a GeForce 910M and 920M from Nvidia. For games, the drivers however are not that fast updated and tested as with GeForce graphics cards.

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 HD Graphics 620 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.
