The Intel HD Graphics 4000 (GT2) is a processor graphics card that is included in the Ivy Bridge processors of 2012 (3rd generation of core, e.g. Core i7-3770). The base clock can be automatically overclocked using Turbo Boost technology. Depending on the processor model, the base and turbo clock rate may differ greatly resulting in different graphics performance of ULV parts compared to high-end desktop and laptop quad-core parts.
Compared to the Intel HD Graphics 3000 in Sandy Bridge CPUs, the HD 4000 card was completely redesigned and offers improved DirectX 11 capable shaders, Hardware Tessellation, a dedicated level 3 cache (before the Last Level Cache LLC of the CPU) and DirectCompute support. The IPC (instructions per clock) can therefore be even 2x as fast as with Sandy Bridge and overall up to 60% more performance (3DMark Vantage) should be possible.
First benchmarks position the HD Graphics 4000 (in a fast quad core desktop CPU) on a level with a dedicated Nvidia GeForce GT 330M and therefore above the AMD processor graphics Radeon HD 6620G. In our extensive tests with games the HD Graphics 4000 was able to beat the HD 6620G in a fast Core i7-3820QM by about 15%. In the slower i7-3610QM and a dual core i5 it was on a similar level as the 6620G. Therefore, casual gamers that wont mind reducing the quality settings in high end games, may be happy with the performance of the HD Graphics 4000. Beware, that the HD Graphics 4000 is used with different clock speeds depending on the CPU model. The ULV CPUs (Core ix-3xx7U) for example feature lower clock speeds and cant maintain the Turbo frequency as good as the 35 - 55 Watt models. Therefore, the ULV version is about 30% slower on average.
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 (depends on how the HD 4000 is used in the laptop - maybe only with a DisplayPort / eDP) as AMD offers with theirs Eyefinity support (up to 6 displays). DisplayPort 1.1 (max 2560x1600) and HDMI 1.4 (max 1920x1080 without hacks) are supported by the chip according to Intel.
Due to the 22nm 3D Tri-Gate production process, the power consumption should be relatively low (the development was focused on performance per Watt). The TDP of the whole package (including processor and memory controller) varies between 18 Watt (ULV) up to 45 Watt (mobile quad core) for the consumer laptop CPUs.
Intel UHD Graphics P630

The Intel UHD Graphics P630 (GT2) is a professional integrated graphics card, which can be found in various Xeon desktop and notebook processors of the Coffee-Lake generation. The "GT2" version of the GPU offers 24 Execution Units (EUs) and the clocks depend on the CPU model. Due to its lack of dedicated graphics memory or eDRAM cache, the UHD P630 has to access the main memory (2x 64-bit DDR3L-1600 / DDR4-2133). Compared to the older HD Graphics P630 (Kaby-Lake), the newer UHD GPU is identical but can be clocked slightly higher. Compared to the regular UHD 630, the P630 supports ECC main memory and is intended for professional applications.
Performance
The exact performance of the UHD Graphics P630 depends on various factors like TDP, L3 Cache, memory (DDR3/DDR4) and maximum clock rate of the specific model. However, it should be fairly similar to the HD Graphics 530 and HD Graphics 630 and therefore only suited for low demanding games like Overwatch or Farming Simulator 2017 (low details).
Features
The features of the UHD P630 are the same as for the HD 630 and therefore H.265/HEVC Main10 profile at 10-bit color depth are supported in hardware. Furthermore, HDCP 2.2 is also supported in all chips, which allows Netflix 4K videos, for instance. HDMI 2.0 however is still only supported with an external converter chip (LSPCon).
Power Consumption
The UHD Graphics P630 can be found in several notebook and desktop processors of different TDP classes.
