Intel Iris Pro Graphics 5200 vs Intel UHD Graphics 605

Intel Iris Pro Graphics 5200

The Intel Iris Pro Graphics 5200 (GT3 + eDRAM), also called the HD Graphics 5200, is a processor graphics card that is included in some of the Haswell processors of 2013 (e.g. Core i7-4750HQ). It represents the highest configuration of the integrated graphics unit (40 execution units) and also has an additional eDRAM cache (128 MB on-package, 77 mm², 102 GB/s). The base clock can be automatically overclocked using Turbo Boost technology. Depending on the processor model, the base and turbo clock rates may differ (usually up to 1200 - 1300 MHz), resulting in varying graphics performance between CPU models.

In comparison to the HD 4000, the graphics core has been modified extensively. The Iris Pro 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.

Thanks to the fast eDRAM memory, the average performance of the Iris Pro is only about 15 percent behind the dedicated mid-range cards GeForce GT 650M and GT 750M (DDR3 versions). This makes the Iris Pro even faster than AMDs Radeon HD 8650G and the fastest integrated GPU of 2013. Therefore, many current games can be played fluently in medium or high detail settings and a resolution of 1366 x 768 pixels. In some older or less demanding titels like Diablo III or Fifa 2013, even higher resolutions or quality settings may be possible.

Due to the 22nm 3D Tri-Gate production process, power consumption should be relatively low. The Iris Pro can be found on certain quad-core Haswell CPUs in the 47 Watt TDP range.

Intel UHD Graphics 605

The Intel UHD Graphics 605 is an integrated processor graphics unit from the Gemini Lake generation (e. g. Pentium Silver N5000), which was announced late 2017. The GPU can convince with low consumption figures, but the performance is only in the low-end segment and is rarely sufficient for modern games. Being the maximum configuration of the Gemini Lake GPU, the UHD Graphics 605 is equipped with 18 Execution Units (EUs) running at up to 750 MHz. The technical specifications of the GPU are based on Intel's Gen9 architecture, which is also used for the more expensive Skylake series and also in the predecessor HD Graphics 505.

Due to its lack of dedicated graphics memory or eDRAM cache, the UHD 605 has to access the main memory via processor (2x 64bit DDR4/LPDDR4-2400).

Performance

The UHD Graphics 605 offers a similar performance as the Intel HD Graphics 505 in the Apollo Lake SoCs (same Gen 9 architecture). Therefore, the GPU is only suited for some very low demanding games like Dirt Rally or Sims 4.

Features

The video engine decodes H.265/HEVC (8b and 10b) and VP9 completely in hardware. Up to three displays can be connected via DP 1.2a/eDP 1.3 or HDMI 2.0a (including HDCP 2.2).

Power Consumption

The TDP of the whole Pentium Silver N5000 chip is 6 Watts by default, so the GPU is primarily used for (often passively cooled) netbooks or thin notebooks. The TDP can also be reduced to 4.9 Watts, but this will obviously affect the performance.
