As 2020 closes in, more details for Intel's 10th Generation Comet Lake-S Desktop CPU family have started leaking out. Well, the family was already leaked by us a while back but the new leaks come from various listings in 3DMark's database which has been spotted by Videocardz (via Tum_Apisak, _Rogame).

Intel's 10th Gen Comet Lake-S Desktop CPUs Leak Out - Core i5-10600, Core i5-10600T, Core i5-10400, and Core i3-10300

Starting off with the details, the three processors that have been spotted weren't included in the list which we posted back in November but these will also be a part of the 10th Generation CPU family. The newly spotted parts include the 6 core, Core i5-10600, Core i5-10400 & Core i5-10600T, and the 4 core, Core i3-10300. One of the key changes for the 10th Gen family would be support for multi-threading across all SKUs, unlike the 9th Gen parts which had multi-thread disabled on many mainstream and high-end SKUs. This change has been made due to rising competition from AMD's Ryzen desktop CPU family.

Following are some of the main platform features of the 10th Generation Comet Lake-S family:

Intel Core i5-10600 & Core i5-10600T 65W/35W 10th Gen Desktop CPUs

In terms of specifications, Core i5-10600 is a 6 core and 12 thread processor, featuring a base clock of 3.3 GHz and a boost clock which is likely to be 4.5 GHz (single-core). This is a tad bit faster than Core i5-10500, which is also a 6 core and 12 thread chip, but has a base clock of 3.2 GHz and a boost clock of 4.3 GHz (single-core). Both chips are suggested to feature a 65W TDP with Core i5-10600K getting an unlocked design which is most likely to feature a TDP of 95W.

HKEPC even managed to get listings for the Core i5-10600T, which is also a 6 core and 12 thread SKU but should feature a much lower TDP of 35W. This chip would also come with lower clocks of 2.4 GHz base and 4.0 GHz boost. Compared to Core i5-9600T, the chip offers a 200 MHz overall increase to the base and 300 MHz increase to the boost clocks which is impressive for a T-series part.

Intel Core i5-10400, Entry-Level 6 Core and 12 Thread Desktop CPU

The folks over at HKEPC also mention Core i5-10400 which is an entry-level 6 core and 12 thread 10th, Gen Desktop CPU. The chip is said to feature a base clock of 3.5 GHz and a boost frequency of 4.1 GHz. Again, this is a nice boost over the 2.90 GHz base and 4.1 GHz boost of previously released Core i5-9400, which had 6 cores and 6 threads with the same clock speeds.

The other part is the Core i3-10300 which is a 4 core and 8 thread CPU with a base clock of 3.7 GHz and a boost clock of 4.2 GHz. Now compared to Core i3-9300, Core i3-10300 actually has the same base clock but a lower boost clock of -100 MHz. However, i3-10300 has four extra threads which Core i3-9300 doesn't and that might explain the 100 MHz lower frequency. It could also be possible that these are just engineering sample speeds and the actual clocks could end up being higher. This chip was spotted in the Alienware Aurora 11 Gaming desktop which shows that OEMs already have the chips in their hands.

Currently, the base configuration of the Aurora desktop from Alienware retails at $869.99 US and features Core i5-9400 and a GTX 1650 4 GB graphics card with 8 GB DDR4 memory and a 1 TB hard disk. It seems like Core i3-10300 configuration would retail for around $600-$700 US that makes it a nice option for those who are still after OEM built gaming PCs.

In addition to the CPU specific leaks, a listing of the Core i9-10900 was also spotted with 10 cores and 20 threads. This is still a very early engineering sample with base clocks of 2.50 GHz and the same boost frequency. The interesting thing about this leak isn't the chip itself but the board that it was tested on. The motherboard is the Z490-A PRO which is an upcoming Intel Z490 chipset based board. In another leak, Intel Core i5-10600 can be spotted running on an ASUS B460-Pro board too. The B460 chipset is also part of the 400-series family which is detailed below.

Z490 series motherboards from Gigabyte/AORUS were also listed very recently at EEC. There's also a single W480 motherboard which is part of the new workstation branded chipsets that Intel has in stock for 10th Gen workstation builders:

There are more Z490 boards that were spotted earlier along with benchmarks of a few 10th Gen Desktop CPUs that could be seen here.
