Intel HD Graphics P530 vs Intel HD Graphics 5600 vs Intel HD Graphics (Cherry Trail)

Intel HD Graphics P530

The Intel HD Graphics P530 (GT2) is an integrated graphics unit, which can be found in various Xeon workstation processors of the Skylake generation. The "GT2" version of the Skylake GPU 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 P530 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Performance

Depending on the memory configuration, the HD Graphics P530 is just slightly behind a dedicated GeForce 920M and will handle modern games (as of 2015) in low or medium 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 P530 can be found in mobile quad-core Xeon processors with 45 W TDP.

Intel HD Graphics 5600

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.

The HD Graphics 5600 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 is now able to 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

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.

Intel HD Graphics (Cherry Trail)

The Intel HD Graphics (Cherry Trail) is an integrated graphics card in the Cherry-Trail SoCs (e.g. Atom x7-Z8700). Based on a Broadwell GPU (Intel Gen8) and supports DirectX 11.2. Depending on the SoC offers 12 or 16 EUs.

Atom x7-Z8700: 16 EUs @ 200 - 600 MHz, dual-channel memory
Atom x5-Z8500: 12 EUs @ 200 - 600 MHz, dual-channel memory
Atom x5-Z8300: 12 EUs @ 200 - 500 MHz, single-channel memory

In Windows, gaming is limited to less demanding or quite old games. Using Android, even high end 3D games should run fluently. For example Team Fortress 2 was running on the Surface 3 (x7-Z8700) only in lowest settings and 1280x720 fluently (11 - 69 fps range).

The integrated video decoder is able to display even 4K videos (H.264 tested) fluently.

The Intel HD Graphics GPU in our review sample of the MS Surface 3 (Atom x7-Z8700) only supported DisplayPort 1.1 as it seems, as 4K (3840x2160) with 30 Hz was the maximum Refresh Rate we could achieve (no 60 Hz selectable with the pre-installed drivers).
