For the current intel chipset (panther point), there seems to plenty of baseless recommendations being thrown around.
Example recommendation thread
- OP - Planning on an i3 build
- Rec - Microcenter can't be beat, current i3 3225 and z77 combo for $185
- Next - Don't use z77, go with this $70-$90 H77 for HTPC
Why is this? Since z77 is associated with it's increased overclocking potential, many think that's all it can be used for. Why go with an h77 over a z77 at the same price or pay more for an h77?
A little background on the Platform Controller Hub
- Microchip included in all intel compatible motherboard since 5 series
- Controls memory allocation, pci instructions, etc
- Think of it as the assembly block between the CPU and the other components
for more info.
For those interested, a decent comparison table between intel chipsets can be found here
. Notice Cougar Point has a TDP of 6.1W while Panther Point uses 6.7W, but that cannot account for the potential savings by bringing memory and pci into the chipset.
Now for the part that makes more sense . . . The uk.hardware.info site did a couple of different motherboard comparison tests for power usage. Here are some H77 and Z77 results, I'll just link right to the power consumption. Here is the Z77
, but the more interesting chart is within the h77 roundup.
Here is the H77
, and it includes the z77 results (H series are red bars, Z is blue)
Notice the lowest power consumption at idle actually comes from a Gigabyte Z77MX-D3H at 24W
The H77 version of that board uses more
power at idle, consuming 26.4W
It would also be worth noting, that as z77 is typically the higher end board it would usually come with higher quality capacitors (longer life span).This is my reasoning for why I'd never pick H over Z unless there was a reasonable price advantage, and I'd definitely never pay more
to avoid the Z boards
