Intel HD Graphics 610 vs Intel Iris Graphics 5100

Intel HD Graphics 610

The Intel HD Graphics 610 (GT1) is an integrated graphics unit, which can be found in low-end ULV (Ultra Low Voltage) processors of the Kaby-Lake generation. This "GT1" version of the Skylake GPU offers 12 Execution Units (EUs) clocked at up to 950 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 610 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

The successor of the HD 610 is the renamed UHD Graphics 610 in the Whisky-Lake and Comet-Lake Pentium CPUs.

Performance

Depending on various factors like memory configuration, the HD Graphics 610 should similar to the old Skylake HD Graphics 510 and therefore can only handle non demanding games. E.g. Farming Simulator 17, World of Warships or Dota 2 Reborn can be played on low settings.

Features

The revised video engine now supports H.265/HEVC Main10 profile in hardware with 10 bit colors. Furthermore, Googles VP9 codec can also be hardware decoded. The Pentium chips should already 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 HD Graphics 610 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.

Intel Iris Graphics 5100

The Intel Iris Graphics 5100 (GT3), also called HD Graphics 5100, is a processor graphics card included in some of the Haswell processors of 2013. It represents the highest configuration of the integrated graphics unit (40 execution units), but lacks the additional eDRAM cache of the Iris Pro Graphics 5200. The base clock can be automatically overclocked using Turbo Boost technology. 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.

The performance of the Iris Graphics 5100 is about 20 percent above the HD Graphics 5000, which can be found in ULV CPUs of the 15W class. In a best case scenario, the IGP machtes a dedicated GeForce GT 640M LE. In other cases, however, the performance is only at the level of the GeForce GT 620M due to the limited memory bandwidth. Current games (as of 2013) can be played fluently in low or medium detail settings and a resolution of 1.024 x 768 or 1.366 x 768 pixels.

Due to the 22nm 3D Tri-Gate production process, power consumption should be relatively low. The Iris Graphics 5100 can be found on certain ULV dual-core Haswell models in the 28 Watt TDP range.
