The Intel HD Graphics (Broadwell) (GT1) is an integrated Broadwell graphics card revealed in Q1 2015. It can be found in several low-end CPUs such as the Pentium 3805U or Celeron 3755U. The so-called GT1 GPU offers 12 EUs (Execution Units) and therefore somewhat more shader power than the previous HD Graphics (Haswell). The clock range may depend on the specific model it is built into.
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). In case of the GT1 version, the shader arrays called "subslice" have been reorganized and now offer 6 Execution Units (EUs) each. Two subslices form a "slice" for a total of 12 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 (Broadwell) represents the low-end version of the Broadwell GPU family and consists of one slice with 12 EUs. Beyond that, there is also a mid-range variant (GT2, 24 EUs) as well as higher-end models (GT3/GT3e + eDRAM, 48 EUs).
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.
Performance
Even though the HD Graphics (Broadwell) is clocked a bit lower, the performance should be clearly above the HD Graphics (Haswell) and similar to the HD Graphics 4000. Nevertheless, only a few games as of 2014/2015 will run fluently at (very) low settings, e.g. Dota 2 or Sims 4.
Power Consumption
Utilizing a new 14 nm process, the HD Graphics (Broadwell) can be found in ULV models (15 W) as well as regular dual core CPUs (37 W, not yet presented). The TDP is flexible and can be further reduced, which has a significant impact on performance.
The Intel HD Graphics 5600 (GT2) is an integrated graphics card of the Broadwell generation. It can be found in standard voltage CPUs (47 W) and offers 24 EUs (Execution Units). The clock range may depend on the model it is built into (Core i7-5700HQ: max. 1050 MHz with Turbo Boost).
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.

Performance
Thanks to its improved architecture and the additional EUs, the HD Graphics 5600 is about 20 percent faster than the Haswell-based HD 4600 (20 EUs), but still somewhat slower than dedicated low-end GPUs like a GeForce 920M or Radeon R7 M360. Most games as of 2014/2015 will be playable only in low settings (and sometimes not even that).
Power Consumption
The whole Broadwell chip is specified at 47 W TDP (i7-5700HQ) and therefore best suited for notebooks 14-inches in size and above. We tested the power consumption of the GPU with HWInfo sensors in a Core i7-5600HQ (MSI GP62). Idle on the Windows desktop the HD 5600 needed on average 0.04 Watt. Running World of Warships in high details, 9.6 Watt were used by the graphics card (whole CPU needed 41 Watt). In comparison, when we activated the dedicated GeForce 940M, the GPU part needed 0.4 Watt and the whole CPU 29 Watt.
The Intel HD Graphics (Skylake) (GT1) is an integrated graphics unit, which can be found in low-end ULV (Ultra Low Voltage) processors of the Skylake generation. In most CPUs, this GPU was named Intel HD Graphics 510 or Intel HD Graphics 515 (see both pages for benchmarks and information).
This "GT1" version of the Skylake GPU offers 12 Execution Units (EUs) clocked at up to 800 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD Graphics has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).
Performance
Depending on various factors like memory configuration, the HD Graphics should perform similar to the older HD Graphics 4200 and will handle only some older and less demanding games in lowest settings.
Features
The revised video engine now decodes H.265/HEVC completely in hardware and thereby much more efficiently than before. Displays can be connected via DP 1.2 / eDP 1.3 (max. 3840 x 2160 @ 60 Hz), whereas HDMI is limited to the older version 1.4a (max. 3840 x 2160 @ 30 Hz). However, HDMI 2.0 can be added using a DisplayPort converter. Up to three displays can be controlled simultaneously.
Power Consumption
The HD Graphics (Skylake) can be found in mobile processors specified at 6 W TDP and is therefore suited for passively cooled 2-in-1 laptops and tablets.
