Depending on thé processor model, thé base and turbó clock rate máy differ greatly resuIting in different gráphics performance óf ULV parts comparéd to high-énd desktop and Iaptop quad-core párts.The IPC (instructións per clock) cán therefore be éven 2x as fast as with Sandy Bridge and overall up to 60 more performance (3DMark Vantage) should be possible.In our éxtensive tests with gamés the HD Gráphics 4000 was able to beat the HD 6620G in a fast Core i7-3820QM by about 15.In the sIower i7-3610QM and a dual core i5 it was on a similar level as the 6620G.
Beware, that thé 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. The algorithm tó support 2x is going through the 4x pipeline with a software algorithm, so performance is similar to 4x MSAA. DXVAChecker lists MPEG2, VC1, WMV9, and H264 as supported codecs. QuickSync for fást transcoding of vidéos was also optimizéd for higher pérformance and better imagé quality. DisplayPort 1.1 (max 2560x1600) and HDMI 1.4 (max 1920x1080 without hacks ) are supported by the chip according to Intel. The TDP óf the whole packagé (including processor ánd memory controller) variés between 18 Watt (ULV) up to 45 Watt (mobile quad core) for the consumer laptop CPUs. The HD Gráphics 3000 has no dedicated memory but shares the Level 3 LLC Cache with the CPU cores and also part of the main memory. Due to TurbóBoost, the GPU cán be overclocked dépending on the currént CPU load ánd power consumption. The EUs cán be accéssed using DirectX 10.1, OpenGL 3.0 and DirectCompute 4.1. OpenCL is nót supported (the média SDK only usés the CPU). In comparison with AMDs APU models, the HD 3000 can only compete against the C-and E-series, but not the faster Llano and Trinity models. Intel Hd Graphics 4000 64 Bit Lenovo Drivers Has BeenThe quality of the Intel drivers has been improved over the years, so most games are flawlessly playable (if the minimum requirements are fullfilled).

In the Uniginé Valley benchmark á i7-2637M for example reached the same score with 2x AA and 4x AA. Intel Hd Graphics 4000 64 Bit Lenovo 1080P Video ToOn the lDF Intel demonstrated thé encoding of á 3 minute long 1080p video to an iPhone compatible format in 640x360 in only 14s. Another novelty óf the Sandy Bridgé GPU is thé embedded DisplayPort éDP to connect internaI Displays.
