Taking a quick look at the block diagram, the most discernable difference between the H61 and H67 chipset is the lack of SATA 6Gb/s support on the former. The H61 chipset was only designed with the capability of running four SATA ports at 3Gb/s and ten USB 2.0 ports (compare to 14 USB 2.0 on the P67/ H67). There is also the lack of USB 3.0 support, a feature common to all current Intel chipsets as well as the use of Intel Rapid Storage Technology or RAID functionality.
So essentially the H61 is a cut-down version of H67, lacking the powerhouse and premium speed features that come with a higher price tag. Unless you need SATA 6G for an expensive SSD, or USB 3.0 for speedy data transfers, then the H61 will do just fine for most users, especially those on a tighter budget.
There are two versions of the new Intel HD graphics, and both are clocked the same, but HD 2000 has 6 execution units while HD 3000 has 12. Unfortunately the HD 3000 is only available on the "K" series of CPU’s from Intel, which is really ironic since paying more money for a “K” series chip defeats the purpose of going with a H67 or H61 chipset, since neither support any CPU overclocking and that is what the “K” series chips are really made for.
The new GPUs support the HDMI 1.4 standard with 3D stereoscopic playback, and hardware encoding for H264 and MPEG2 video, as well as a few image enhancement features like total color control, skin tone detection/correction and auto contrast. The feature set has also progressed to Shader model 4.1 and DirectX 10.1 from Intel’s 5 series chipsets.
It’s a bit tough to see the detail but the chart below is a quick summary.
With that quick summary, let’s move onto the specifications for the ASRock H61iCafe motherboard.
