Intel UHD Graphics 600 vs Intel HD Graphics 5500 vs Intel HD Graphics 610

Intel UHD Graphics 600

The Intel UHD Graphics 600 is an integrated processor graphics unit from the Gemini Lake generation (e. g. Pentium N4100), 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 lowest configuration of the Gemini Lake GPU, the UHD Graphics 600 is equipped with 12 of the 18 Execution Units (EUs) running at up to 700 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 600 offers a similar performance as the Intel HD Graphics 500 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 N4100 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 4.8 Watts, but this will obviously affect the performance.

Intel HD Graphics 5500

The Intel HD Graphics 5500 (GT2) 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 i5-5200U or i7-5600U. While Core i5 and Core i7 chips feature 24 EUs, the Core i3 version offers just 23 EUs. Depending on the specific CPU, the maximum GPU frequency varies between 850 and 950 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 5500 represents the mid-range version of the Broadwell GPU family and consists of one slice with 24 EUs. Beyond that, there is also a low-end variant (GT1, 12 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

Depending on the specific CPU, the maximum GPU frequency varies between 850 and 950 MHz. Due to the low TDP, however, the average clock in 3D applications will be somewhat lower.

Equipped with fast dual-channel memory, the HD Graphics 5500 outperforms the HD Graphics 4400 (Haswell, 20 EUs) by 20 - 25 percent and also beats the HD Graphics 5000 (Haswell, 40 EUs). However, even a low-end dedicated GeForce 820M ist about 10 - 30 percent faster than the HD 5500. Games as of 2014/2015 will usually run fluently only at (very) low settings.

Power Consumption

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 (7.5 or 10 W), which has a significant impact on performance.

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.
