difference between sandy bridge and ivy bridge

The site claims Ivy Bridge employs thermal paste between the die and heat spreader, which differs from the fluxless solder that lurks under the lid of Sandy Bridge CPUs. It’s possible that a less efficient heat transfer interface could be leading to higher temperatures for Ivy.Ĭurious, we asked Intel about the interface between the Ivy Bridge die and the heat spreader. points out there’s another factor to consider: the interface between the CPU die and heat spreader.

The question is: why does Ivy appear to reach higher temps when overclocked than Sandy Bridge? Is it just the additional power draw being turned into more heat? Is it a thermal density issue, since Ivy’s heat output is concentrated into a much smaller die area than Sandy’s? Or is it something else?

The additional power is dissipated as heat, which contributes to those high temperatures. Other reviews have observed similarly scorching temperatures, so it’s not just our sample.Īs we noted earlier this week, the Core i7-3770K’s power consumption increases dramatically when it’s pushed to 4.9GHz-as it should, given the proportional relationship between CPU power consumption, frequency, and the square of the voltage. However, when we pushed to 4.9GHz on 1.35V, the temperature soared past 100☌. With a single-fan air tower, our chip ran at a reasonable 50-60☌ when clocked to 4.4-4.5GHz at its default voltage. If you read our Ivy Bridge coverage carefully, you’ll know that we observed some rather high temperatures when overclocking the Core i7-3770K.
