Intel HD Graphics 405 (Braswell) vs Intel HD Graphics 4200 vs Intel HD Graphics 6000
Intel HD Graphics 405 (Braswell)► remove
The Intel HD Graphics 405 (Braswell) is an integrated graphics card in the low end SoCs of the Braswell series (e.g. Pentium N3710). 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.
The GPU was simply called Intel HD Graphics (Broadwell) before 2016 and included also the slower 12 EUs version in the Celeron model. The Graphics 405 name currently only stands for 16-core-versions in Pentium models. The 12 EU version is now called Intel HD Graphics 400.
The clock speed and memory configuration can still vary from model to model.
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.

The Intel HD Graphics 4200 (GT2) is a processor graphics card that is included in some of the ULV Haswell processors of 2013 (4th generation core). The relatively low base clock can be automatically overclocked using Turbo Boost technology.
In comparison to the HD 4000, the graphics core has been modified in several details. The GPU supports DirectX 11.1, OpenCL 1.2 und OpenGL 4.0. It also features an improved decoder for 4K videos and the fast Quick Sync encoder.
The performance of the HD Graphics 4200 is clearly below the HD 4600 and HD 4400, since the GPU is designed for ULV models of the Y-series (11.5 W). Therefore, the clock rates are relatively low. Compared to a similar clocked HD 4000, the HD 4200 is somewhat faster due to architectural improvements and an increased number of execution units: The GT2 version integrates 20 EUs, compared to 16 EUs for the old HD 4000.
In simple games like Anno 2070 or Counter Strike: Global Offensive, the performance is sufficient to handle low settings and 1024 x 768 pixels. Many current titles like Battlefield 4, however, are not playable even at minimum graphic quality. Detailed benchmarks can be found below.
Due to the 22nm 3D Tri-Gate production process, the power consumption is relatively low and suitable even for tablets. In addition to the TDP of 11.5 watts, the Y-series CPUs are rated at an SDP (average power consumption) of 4.5 or 6 watts (depending on the model).

The Intel HD Graphics 6000 (GT3) is an integrated Broadwell graphics card revealed in Q1 2015. It can be found in several ULV SoCs (15 W TDP) such as the Core i5-5250U or i7-5650U. The so-called GT3 GPU offers 48 EUs (Execution Units) and therefore somewhat more shader power than the previous HD 5000 (40 EUs). Depending on the specific CPU, the maximum GPU frequency varies between 950 and 1000 MHz.
Architecture and Features
Broadwell features a GPU based on the Intel Gen8 architecture, which has been optimized in various aspects compared to the previous Gen7.5 (Haswell). Inter alia, the shader arrays called "subslice" have been reorganized and now offer 8 Execution Units (EUs) each. Three subslices form a "slice" for a total of 24 EUs. Combined with other improvements such as larger L1 caches and an optimized frontend, the integrated GPU has become faster and more efficient than its predecessor.
The HD Graphics 6000 represents the top-end version of the Broadwell GPU family and consists of two slices with 48 EUs. Beyond that, there is also a low-end (GT1, 12 EUs), a mid-range (GT2, 24 EUs) and a high-end variant (GT3e, 48 EUs + eDRAM).
All Broadwell GPUs support OpenCL 2.0 and DirectX 12 (FL 11_1). The video engine can now decode H.265 using both fixed function hardware as well as available GPU shaders. Up to three displays can be connected via DP 1.2/eDP 1.3 (max. 3840 x 2160 @ 60 Hz) or HDMI 1.4a (max. 3840 x 2160 @ 24 Hz). HDMI 2.0, however, is not supported.
Depending on the specific CPU, the maximum GPU frequency varies between 950 and 1000 MHz. Due to the low TDP, however, the average clock in 3D applications will be significantly lower. Overall, the HD Graphics 6000 outperforms the previous HD 5000 by 20 - 25 percent and offers a performance slightly below a dedicated GeForce 820M.
Games as of 2014/2015 will usually run fluently only at (very) low settings.
Utilizing a new 14 nm process, the Broadwell ULV chips are specified at just 15 W TDP and therefore suited for thin ultrabooks. The TDP is flexible and can be further reduced (9.5 W), which has a significant impact on performance.
