The Intel Iris Pro Graphics 6200 (GT3e) is an integrated graphics card and the fastest GPU of the Broadwell generation. It is built into several high-end CPUs specified at 47 W TDP. The so-called GT3e GPU offers a fast eDRAM cache as well as 48 EUs (Execution Units) and therefore somewhat more shader power than the previous Iris Pro Graphics 5200. The clock range depends on the model it is built into (up to 1150 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.
The Iris Pro Graphics 6200 represents the high-end "GT3e" version of the Broadwell GPU family and consists of two slices with 48 EUs in total. In addition, there is also a fast eDRAM cache (128 MB), which can be found only on the Iris Pro.
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
Depending on the benchmark, the Iris Pro Graphics 6200 performs similar to a dedicated GeForce GT 750M or GeForce 940M. Many games of 2014/2015 can be played fluently in WXGA resolution (1366 x 768) and medium detail settings. However, very demanding games such as The Witcher 3 will require lower resolutions and/or details.
Power Consumption
Utilizing a new 14 nm FinFET process, the Iris Pro Graphics 6200 is specified at 47 W TDP (entire chip including CPU, GPU and memory controller) and therefore suited for medium-sized notebooks. The TDP is flexible and can be further reduced (37 W), which has a significant impact on performance.
Intel UHD Graphics 617

The Intel UHD Graphics 617 (GT2) is a low-end integrated graphics unit, which can be found in the Y-series of the Amber-Lake generation. This "GT2" version offers 24 Execution Units (EUs) clocked at up to 1050 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the UHD 617 has to access the main memory (2x 64bit DDR3L/LPDDR3). Compared to the old HD Graphics 615 in Kaby-Lake-Y CPUs, the UHD 617 is the same GPU with slightly different clock speeds (depending on the model) and slight power/performance improvements due to the improved 14nm++ process. Compared to the similar UHD Graphics 615 in other Amber Lake models, the 617 looks to be higher clocked (+50 MHz) and has more headroom due to the higher TDP of 7 versus 5 Watt.
Performance
The 3D performance of the UHD 617 depends on the CPU model and the cooling / TDP-setting of the laptop. Furthermore, the used main memory (single channel, DDR3(L), amount) is influencing performance. On average the UHD graphics 617 should be very similar to the Kaby-Lake HD Graphics 615 due to the same architecture and similar speeds. That means that only low demanding games like Farming Simulator 17 or Rocket League are playable in lowest detail settings.
Features
The revised video engine in the HD 615 and UHD 615 / 617 now supports H.265/HEVC Main10 profile in hardware with 10 bit colors. Furthermore, Googles VP9 codec can also be hardware decoded. The UHD 617 should support HDCP 2.2 and therefore Netflix 4K. HDMI 2.0 however is still only supported with an external converter chip (LSPCon).
Power Consumption
The UHD Graphics 617 can be found in Y processors with 7 W TDP and is therefore suited for very thin, mostly passively cooled subnotebooks like the MacBook Air 2018.
