Intel Lists Two New Comet Lake-U CPUs for Thin & Light Laptops

Intel has launched two new low-end Comet Lake-U CPUs (opens in new tab): the Intel Pentium Gold 6405U and the Intel Celeron 5205U, thereby adding two more 14nm chips to the confusing Intel 10th-Generation lineup (opens in new tab).

As spotted by Anandtech (opens in new tab), these two chips eat at the lowest-end of the CPU hierarchy (opens in new tab) and are likely binned (opens in new tab)chips that otherwise do not meet Intel’s requirements for operating as higher-rated parts. Being U-series parts, they are intended to operate in low-power mobile applications, such as thin and light laptops (opens in new tab). Both carry TDPs of 15W.

The Celeron 5205U chip comes with two cores (opens in new tab)that don't use Hyper-Threading (opens in new tab). The spec sheet lists a base frequency (opens in new tab) of 1.9 GHz. 

The Pentium Gold 6405U does use Hyper-Threading on both of its cores and lists a base frequency of 2.4 GHz. 

Pentium and Celeron chips typically do not get Intel’s Turbo Boost feature. Given that the other (Core i3, i5, & i7) Comet Lake U-series chips have lower base frequencies but very high turbo clocks, it's possible that the Celeron 5205U and Pentium Gold 6405U don't have a turbo frequency at all. Intel didn't provide boost information for either chip.

Aboard the chips are also 2MB of L3 cache (opens in new tab), Intel UHD integrated graphics and 12 lanes of PCIe 2.0 (opens in new tab) support.

The MSRP for the chips is $107 for the Celeron 5205U and $161 for the Pentium Gold 6405U. That being said, they'll probably go from Intel to its vendor partners for notably less.
