Intel HD Graphics 4400 vs AMD Radeon RX 6800M

Intel HD Graphics 4400

The Intel HD Graphics 4400 (GT2) is a processor graphics card included in some of the ULV Haswell processors of 2013. The relatively low base clock can be automatically overclocked using Turbo Boost technology. Depending on the processor model, the turbo clock rates may differ, resulting in varying graphics performance between models.

In comparison to the HD 4000, the HD 4400 graphics core has been modified extensively. The GPU now supports DirectX 11.1, OpenCL 1.2 and OpenGL 4.0. It also features an improved decoder for 4K videos and the fast Quick Sync encoder. Compared to the faster 4600, the 4400 offers the same amount of shaders, but lower clock speeds (see table of clock speeds of the different CPU models below).

The performance of the HD Graphics 4400 is somewhat below the HD 4600, since the GPU is designed for ULV models. Therefore, the clock rates are relatively low. Furthermore, the reduced TDP limits the Turbo Boost. Compared to the ULV versions of the Ivy Bridge HD 4000, the HD 4400 is about 20 - 30 percent faster. This performance boost is achieved by architectural improvements and an increased number of execution units: The GT2 version integrates 20 EUs, compared to 16 EUs for the old HD 4000. Depending on the clock rate, the HD 4400 matches the performance of a dedicated Radeon HD 7550M.

Due to the 22nm 3D Tri-Gate production process, the power consumption is relatively low. The HD Graphics 4400 can be found on ULV dual-core Haswell models with a TDP of 15 watts.

AMD Radeon RX 6800M

The AMD Radeon RX 6800M is a mobile high-end graphics card for gaming laptops. It uses the Navi 22 chip based on the new RDNA 2 architecture. It uses all 2,560 shaders (= 40 CUs), 160 TMUs, and 64 ROPs and therefore is similar to the desktop Radeon RX 6700 XT. The 192 Bit memory system connects 12 GB GDDR6 with 2 GHz memory clock. Furthermore, the RX6800M includes 96 MB Infinity Cache. AMD specified 2.3 GHz game clock for 11.8 TFLOPS theoretical performance at a TDP of 145 Watt. This means the GPU is in theory 11% faster than the RX 6700M.

The gaming performance of the RX 6800M (e.g. in the Asus ROG Strix G15) is positioned between a RTX 3070 and 3080. In some games the GPU can even surpass a fast RTX 3080. On the other side, when Raytracing effects are activated, it falls behind the GeForce GPUs.

The Navi 22 chip is manufactured at TSMC in the modern 7nm process.
