Intel HD Graphics 400 (Braswell) vs Intel HD Graphics (Sandy Bridge) vs Intel HD Graphics (Haswell)

Intel HD Graphics 400 (Braswell)

The Intel HD Graphics 400 (Braswell)  is an integrated graphics card in the low end SoCs of the Braswell series (2016 Celeron models). It is based on the same architecture as the integrated GPU of the Broadwell graphics cards (e.g. HD Graphics 5300), but offers less shader cores and slower clock speeds.

It is a rename from the Intel HD Graphics (Braswell) card that included the faster 16 EU model in the Pentium SoCs. See the Intel HD Graphics Braswell graphics card page for benchmarks.

The performance depends on the processor (different boost speed for the GPU) and the used memory.

Gaming performance ist still only suited for older or less demanding games. Often also the processor is limited gaming performance (e.g. in the dual-core N3000).

The SoC also integrates a video decoding engine that should be able to handle 4K H.265 videos.

Intel HD Graphics (Sandy Bridge)

The Intel HD Graphics (Family) is a processor graphics card which is integrated in the cheap Celeron and Pentium model of the Sandy Bridge generation. It is similar to the Intel HD Graphics 2000 and not with the processor graphics of the older Arrandale dual-core processors (which bears the same name). 

Depending on the processor, the HD graphics offers a different base and Turbo Boost clock speed. Currently there are three different models:

• Power Saving e.g. Celeron 847: base 350MHz, Turbo 800MHz
• Celeron e.g. Celeron B810: base 650MHz, Turbo 950MHz
• Pentium e.g. Pentium B950: base 650MHz, Turbo 1100MHz

Furthermore, the slow CPU performance of some models may influence the games a lot. For example, although the GPU in the Celeron B710 differs not much from the Pentium B950, the gaming performance was clearly worse and many games were unplayable.

As the Intel HD Graphics 3000 and 2000, the processor graphics card is able to use part of the last level cache of the processor (2MB usually for the entry level CPUs). This could be seen as a small amount of very fast dedicated memory.

Altought 2x Antialiasing (AA) is supported, the chip is as fast as when rendering 4x AA. In the Unigine Valley benchmark a similar HD 3000 i7-2637M for example reached the same score with 2x AA and 4x AA.

The feature set compared to the HD Graphics 3000 is also reduced in these entry level CPUs. E.g. Intel Quick Sync (for de- and encoding of HD videos), In Tru 3D, Clear Video HD are usually deactivated.

Intel HD Graphics (Haswell)

The Intel HD Graphics (Haswell) is an integrated graphics card in the Haswell codenamed processors (Celeron and Pentium). It is the successor the the Intel HD Graphics in the Ivy Bridge CPUs and performs slightly better. Depending on the processor model, the base and turbo clock rates may differ, resulting in varying graphics performance between CPU models.

In comparison to the HD 4000, the graphics core has been modified extensively. The GPU 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 (deactivated in many entry level models).

The Performance of the HD Graphics (Haswell) is similar to the old HD Graphics 3000 or the AMD Radeon HD 8250. Only a few modern games like Dota 2 can be played fluently in very low details and resolutions.

Due to the 22nm 3D Tri-Gate production process, the power consumption should be relatively low (the development was focused on performance per Watt). The GPU can be found in ULV models and regular (37 W) dual core CPUs.
