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.
OPENGL 4.4 AMD RADEON SOFTWARE
The algorithm to support 2x is going through the 4x pipeline with a software algorithm, so performance is similar to 4x MSAA.

However, 2x is only supported through software. Therefore, the ULV version is about 30% slower on average.Ī speciality of the Ivy Bridge GPUs is that 4x MSAA is supported in hardware now. 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. Beware, that the HD Graphics 4000 is used with different clock speeds depending on the CPU model. 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.

In the slower i7-3610QM and a dual core i5 it was on a similar level as the 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%. 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.įirst 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. 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.Ĭompared 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 base clock can be automatically overclocked using Turbo Boost technology. 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. Stay tuned for Catalyst 14.4 testing on Linux in the coming days at Phoronix.Intel HD Graphics 4000 ► remove from comparison The release notes are rather lengthy and extensive compared to some of the releases in past months, likely in part due to the discussions I had with AMD and the bit of heat they were given over lack of Linux Catalyst release notes coming down to engineering resources.
OPENGL 4.4 AMD RADEON DRIVER
The release notes for today's Catalyst 14.4 Linux driver release can be found at AMD.com. The OpenGL 4.4 support comes to the Catalyst Linux driver with adding support for the following OpenGL extensions: ARB_buffer_storage, ARB_enhanced_layouts, ARB_query_buffer_object, ARB_clear_texture, ARB_texture_mirror_clamp_to_edge, ARB_texture_stencil8, ARB_vertex_type_10f_11f_11f_rev, ARB_multi_bind, ARB_bindless_texture, ARB_spare_texture, ARB_seamless_cubemap_per_texture, ARB_indirect_parameters, ARB_compute_variable_group_size, ARB_shader_draw_parameters, and ARB_shader_group_vote.Ĭatalyst 14.4 also has numerous bug-fixes including fixes for Mesa's Piglit regression tests and handling of various OpenGL bugs, including even Enemy Territory: Quake Wars fixes. The R9 295X also costs $1500 USD, so it's out of the hands of most Linux gamers. However, given the rather poor and not too useful CrossFire support under Linux, the R9 295X will likely not be too beneficial. The R9 295X graphics card was announced earlier this month and consists of two R9 "Hawaii" GPUs and 8GB of video memory.
OPENGL 4.4 AMD RADEON FULL
Key features of the AMD Catalyst 14.4 RC for Linux include support for the AMD Radeon R9 295X graphics card - AMD's newest high-end graphics card, full support for OpenGL 4.4, official Ubuntu 12.04.4 LTS support, and a number of bug-fixes. The big items with this release include R9 295X GPU support and full support for OpenGL 4.4.

AMD has kicked off a new week by releasing the Catalyst 14.4 release candidate for Linux.
