Intel HD Graphics P530 vs Intel HD Graphics 400 (Braswell) vs Intel HD Graphics (Ivy Bridge)

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 400 (Braswell)

The Intel HD Graphics 400 (Braswell)  is an integrated graphics card in the low end SoCs of the Braswell series (2016 Celeron models). It is based on the same architecture as the integrated GPU of the Broadwell graphics cards (e.g. HD Graphics 5300), but offers less shader cores and slower clock speeds.

It is a rename from the Intel HD Graphics (Braswell) card that included the faster 16 EU model in the Pentium SoCs. See the Intel HD Graphics Braswell graphics card page for benchmarks.

The performance depends on the processor (different boost speed for the GPU) and the used memory.

Gaming performance ist still only suited for older or less demanding games. Often also the processor is limited gaming performance (e.g. in the dual-core N3000).

The SoC also integrates a video decoding engine that should be able to handle 4K H.265 videos.

Intel HD Graphics (Ivy Bridge)

The Intel HD Graphics (Ivy Bridge) is an integrated graphics card in the mobile Ivy Bridge codenamed processors (Celeron and Pentium). It is the successor the the Intel HD Graphics 2000 in the Sandy Bridge CPUs and performs between the old HD 2000 and 3000 GPU. 

Compared to the faster HD Graphics 4000, the HD Graphics features less Execution Units (6 versus 16) and only one texture sampler. Therefore, the performance is clearly worse and only suited for low demanding gaming. Intel states a 10 to 15% higher performance compared to the old Sandy Bridge based HD Graphics 2000 (see our benchmarks below), which is similar to AMDs low-end GPUs like the integrated Radeon HD 8210. Therefore, only casual games with low requirements are playable.

A speciality of the Ivy Bridge GPUs is that 4x MSAA is supported in hardware now. However, 2x is only supported through software.  The algorithm to support 2x is going through the 4x pipeline with a software algorithm, so performance is similar to 4x MSAA.

The integrated video decoder called Multi Format Codec Engine (MFX) was also improved and should allow even simultaneus 4K video decoding. DXVAChecker lists MPEG2, VC1, WMV9, and H264 as supported codecs. QuickSync for fast transcoding of videos was also optimized for higher performance and better image quality.

Another new feature is the support for up to 3 independent displays (maybe only with a DisplayPort) as AMD offers with theirs Eyefinity support (up to 6 displays).

Due to the 22nm 3D Tri-Gate production process, the power consumption should be relatively low (the development was focused on performance per Watt).
