Intel may not have officially shown its desktop aimed 10th Gen Comet Lake-S desktop CPU lineup at CES 2020 but benchmarks for the Core i9 10 core and the Core i5 6 core processors have leaked out online. The latest leak comes from a Taobao DIY market reporter (via Momomo) who has posted a video of the two ES (Engineering Sample) chips and tested them on an OEM motherboard, featuring the new LGA 1200 socket.
Intel 10th Gen Comet Lake-S 10 Core & 6 Core Desktop CPU Engineering Samples Leaked & Benchmarked, New Socket Layout Confirmed
The two processors tested might be compared to the Core i9-10900K and the Core i5-10600K that leaked out last week but are in fact entirely different chips that are in ES (Engineering Sample) state which means that they aren't based on the final die/revision/specs. This is made clear with CPU-z screenshots which shows that the Core i9 10 core chip has a base clock of just 2.50 GHz which is much lower than the expected base clock of 3.7 GHz on the Core i9-10900K. Even the 65W, Core i9-10900 has a higher base frequency of 2.8 GHz. The same is true for the Core i5 6 core chip which has a base clock of 3.0 GHz and that too is lower than both, the 'K' 125W and the standard 65W variants.
Furthermore, the leaker mentioned that both chips weren't yet optimized with the Dell B460 OEM motherboard that they used to test the processors. One interesting thing is to note is that both ES chips feature their socket alignment notches at the bottom which is a design revision for the new LGA 1200 socket. The existing 9th Gen processors feature the same notch on the upper side. It can also be seen that the 10 core SKU features an IHS similar to the Intel Core i9-9900KS (Coffee Lake refresh) while the 6 core SKU features an IHS similar to the Core i7-8700K (Coffee Lake).
The BIOS for the B460 OEM motherboard also had various issues and the 10 core chip was only reaching boost clocks of 3.3 GHz as opposed to the final 4.8-4.9 GHz clock speeds. This was an issue with both chips so the performance is pretty lackluster in all of the benchmarks that were run.
In Cinebench R20, the 10 core scored 4215 points and the 6 core scored 2928 points. In Cinebench R15, the 10 core scored 1957 points and the 6 core scored 1199 points. You can see how well they compared to other processors in the following charts:
There's also a section that showcases the temperatures of both chips at full load. The 10 core maxed out at 51C while the 6 core maxed out at 53C. Since these aren't running at the final clock speeds, expect the retail variants to be much hotter and more power-hungry. A selection of games was also run, showcasing the 10 core lead in multi-thread optimized titles but the two chips were mostly similar in the majority of the gaming tests which were run. A leaked Intel slide already gave us a glimpse of what to expect from the flagship Core i9-10900K CPU.
The Intel Core i9-10900K was compared against the Core i9-9900K that has 8 cores and 16 threads. Since these are not public slides but internal performance projections, Intel also listed down the PL2 power states for each chip, which shows the maximum TDP when all cores are hitting the turbo frequency. The Core i9-9900K is a 95W and 210W (PL2) chip while the i9-10900K is a 125W and 250W (PL2) chip.
Intel 10th Gen Comet Lake-S Unlocked 125W Desktop CPU Family
There are three SKUs in the unlocked lineup which is one less than what we were told. There's the flagship Core i9-10900K which is followed by the Core i7-10700K and the Core i5-10600K. The Core i3 variant is missing but it's such a crucial SKU that would be targetting a very competitive market and it would be a bad decision for Intel to not launch an unlocked quad-core part in the budget tier segment.
Intel Core i9-10900K - 10 Cores, Up To 5.3 GHz Single-Core, 4.9 GHz All-Core
The Intel Core i9-10900K will be the flagship part of the 10th Generation Desktop CPU family. Intel has a few tricks up their sleeves to offer even better performance than the Core i9-9900KS. The i9-10900K features 10 cores, 20 threads a total cache of 20 MB and a 125W TDP. The chip has a base frequency of 3.7 GHz and a boost frequency of 5.1 GHz. However, using Intel's Turbo Boost Max 3.0 technology, the chip can boost up to 5.2 GHz on a single-core and what's even better is the 4.9 GHz all-core boost. Some of the features of this particular chip, as detailed by Videocardz, include:
- Up to 4.8 GHz All-Core Turbo
- Up to 5.3 / 4.0 GHz Thermal Velocity Boost Singe / All-core Turbo
- Up to 5.2 GHz Intel Turbo Boost Max 3.0
- Up to 10C and 20T
- Up to DDR4-2933 MHz dual-channel
- Enhanced Core & Memory Overclocking
- Active Core Group Tuning
Here's the interesting part, the chip would also get Thermal Velocity Boost, similar to the current flagship parts. CPUs that support this algorithm, like the Core i9-10900K, would feature even faster boost frequencies of 5.3 GHz (single-core) and 4.9 GHz (all-core). However, as the name suggests, only top-tier cooling solutions would be able to allow full utilization of the Thermal Velocity Boost feature. So unless you rock a high-end AIO liquid cooler or a closed-loop setup, don't expect a sustained velocity boost but rather short bursts until the threshold is hit. It will be interesting to know the full extent of the features that this function has to offer and what kind of cooling would the Core i9-10900K requires in general.
Intel Core i7-10700K - 8 Cores, Up To 5.1 GHz Single-Core, 4.7 GHz All-Core
The Intel Core i7-10700K would be featuring 8 cores and 16 threads. The chip would house 16 MB of total cache and a TDP of 125W. The chip would feature a base clock of 3.8 GHz, a boost clock of 5.0 GHz (single-core) and 5.1 GHz (single-core) with Turbo Boost Max 3.0. The chip will be 100 MHz faster in single-core but slower across all-cores by 100 MHz than the Core i9-9900K which retails for over $500 US. Since this is an i7 part, expect pricing to fall around $350-$400 US.
Intel Core i5-10600K - 6 Cores, Up To 4.8 GHz Single-Core, 4.5 GHz All-Core
The Intel Core i7-10600K would be featuring 6 cores and 12 threads. The chip would house 12 MB of total cache and a TDP of 125W. The chip would feature a base clock of 4.1 GHz, a boost clock of 4.8 GHz (single-core) and 4.5 GHz (all-core). The chip would be faster than the 8th Gen flagship, the Core i7-8700K, featuring a higher base and boost clock across a single and all-cores. The Core i5 should be retailing in the $220-$270 US segment which is a decent price for a fast 6 core and multi-threaded chip.
Intel 10th Gen Comet Lake-S 65W Desktop CPU Family
The rest of the lineup is made up of the 65W SKUs which come in Core i9, Core i7, Core i5, and Core i3 flavors. Having a 65W Core i9-10900 with 10 cores and 20 threads which still boosts up to 4.5GHz across all cores and 4.6 GHz if you include the Thermal Velocity boost is pretty good plus 5.2 GHz on a single-core doesn't sound that bad at all, considering this is a 65W chip (at its base frequency).
The Intel Core i3 lineup is also worth pointing out as it is made up of 3 SKUs which seem to be part of the initial launch family. The Core i3-10320 would be leading with 4 cores, 8 threads at 65W. 8MB of cache, clocks of up to 4.6 GHz in single and 4.4 GHz on all-cores sound decent enough for what is supposed to be a budget chip retailing under $200 US. The full list of SKUs along with their specs can be seen in the table below.

Intel 400-Series Platform and LGA 1200 Socket Support For 10th Gen Comet Lake Desktop CPUs
It is now confirmed that Intel is indeed moving to a new socket with their 400-series boards that will be introduced next year too. While the LGA 1200 socket has the same dimensions as the LGA 1151 socket (37.5mm x 37.5mm), the socket keying has shifted to the left side and Comet Lake is no longer electrically or mechanically compatible with Coffee Lake motherboards. Some details of the new LGA 1200 package and socket for Comet Lake:
- Comet Lake will transition to a higher pin-count package
- Comet Lake LGA will not have backward compatibility with legacy platforms
- No changes to ILM dimensions or thermal solution retention
- Comet Lake LGA improves power delivery and support for future incremental I/O features
- Pin 1 orientation remains the same, but socket keying has shifted left
Blueprints of the LGA 1200 socket (H5) have also been leaked by Momomo_Us, showing the design of the new socket itself and comparing it to the existing LGA 1151 socket (H4).
The pin and socket specific changes between the H5 LGA 1200 and the H4 LGA 1151 socket are detailed in the blueprints posted above. (Image Credits: Momomo_US)
The good thing is that your existing coolers would still be compatible with the LGA 1200 socket so that's one hardware change you shouldn't be worrying about. The Comet Lake-S family will retain support for DDR4-2666 memory UDIMM and support up to 32 GB capacity DIMMs per channel.
Intel plans to have several chipsets deployed in the 400-series family. There would obviously be Z490 which will target the 'K' unlocked SKUs I mentioned above, but aside from that, we are looking at the W480 (Entry Workstation), Q470 (Corporate with Intel vPro), and H410 (Value) chipsets. These would target more corporate and entry tier users. Also interesting to note is that H410 is not pin-compatible with W480 and Q470 chipsets, which reveals a very cut down design for the entry-level chip.
Following are some of the main platform features of the 10th Generation Comet Lake-S family:
- Up To 10 processor cores for enhanced performance
- Up To 30 PCH-H High-Speed I/O lanes for port flexibility
- Up To 40 PCIe 3.0 Lanes (16 CPU, up to 24 PCH)
- Media & Display features for premium 4K content support
- Integrated + Discrete Intel Wireless-AC (Wi-Fi/BT CNVi) Support
- Intel Wi-Fi 6 (Gig+) Support
- Enhanced Core and memory overclock
- Integrated USB 3.2 Gen 2x1 (10 Gb/s) support
- Intel Rapid Storage Technology (Intel RST)
- Programmable (Open FW SDK) Quad-Core Audio DSP
- C10 & S0ix Support for Modern Standby
Intel 400-Series Chipset Family:
| Chipset Name | Intel Z490 | Intel W480 | Intel Q470 | Intel H410 |
|---|---|---|---|---|
| Total HSIO Lanes | 46 Lanes (16 CPU + 30 PCH) | 46 Lanes (16 CPU+ 30 PCH) | 46 Lanes (16 CPU+ 30 PCH) | 30 Lanes (16 CPU+ 14 PCH) |
| Total PCIe 3.0 Lanes (CPU + PCH) | Up To 40 (16 CPU + <24 PCH) | Up To 40 (16 CPU + <24 PCH) | Up To 40 (16 CPU + <24 PCH) | 22(16 CPU + 6 PCIe 2.0) |
| Chipset PCIe 3.0 Lanes | Up To 24 | Up To 24 | Up To 24 | 6 (PCIe 2.0 Only) |
| SATA 3.0 Ports | Up To 8 | Up To 8 | Up To 6 | 4 |
| Maximum USB 3.2 Ports Gen 2 (10 Gb/s) / Gen 1 (5 Gb/s) | 8/10 | 8/10 | 6/10 | 0/4 |
| Tota USB Ports (Maximum USB 3.2 Gen 1 (5 Gb/s)) | 14 (10) | 14 (10) | 14 (10) | 10 (4) |
| Intel RST Technology For PCIe 3.0 storage ports | 3 PCH | 3 PCH | 3 PCH | 0 |

| Overclocking Support | Yes | N/A | N/A | N/A |
| Processor PCIe Express 3.0 Lanes Configuration | 1x16 or 2x8 or 1x8 + 2x4 | 1x16 or 2x8 or 1x8 + 2x4 | 1x16 or 2x8 or 1x8 + 2x4 | 1x16 |
| Display Support (Ports / Pipes) | 3/3 | 3/3 | 3/3 | 3/2 |
| DMI 3.0 Lanes | 4 | 4 | 4 | 4 (DMI 2.0 Only) |
| System Memory Channels / DPC | 2/2 (DDR4-2666) | 2/2 (DDR4-2666) | 2/2 (DDR4-2666) | 2/1 (DDR4-2666) |
In terms of chipset features, W480 would be the most feature-rich of the three chipsets that are mentioned here. Z490 would be the most appealing for the enthusiast and gaming audience, but let's take a look at the mainstream chipsets. The W480 chipset would offer a total of 46 high-speed IO lanes and a total of 40 PCIe Gen 3.0 lanes. The CPUs would retain 16 lanes with the chipset offering up to 24 PCIe 3.0 lanes.
There would be support for up to 8 SATA III ports, 8 USB 3.2 Gen 2 ports or 10 USB 3.2 Gen 1 ports, 14 USB 3.2 Gen ports, and Intel RST. Neither of the three chipsets would feature overclock support since that is restricted to the Z490 chipset but we will get more information on overclocking later on from Intel themselves. Our sources have pointed out a proper launch of Intel's 10th Gen Comet Lake-S desktop CPU family in February 2020.
