The new “Comet Lake” processors are manufactured using the 14nm ++ method and come with new packaging, install in the new LGA1200 socket, and are compatible with the new family of 400 series Intel chipsets consisting of B460 , H410 and Z490, which is also the flagship. Comet Lake processors are not compatible with motherboards with the LGA1151 socket (however, the LGA115x compatible cooling system can be used in a new type of motherboard if it meets the processor heat requirements.
The key elements of Comet Lake’s design remain unchanged from Skylake, but Intel has made several optimizations regarding the operating frequency improvement algorithm, while increasing cores and threads at all price levels. new features that overclockers and enthusiastic users will like (eg new Intel Turbo Boost Max 3.0 technology, HyperThreading enabled / disabled on each core separately, much better voltage / frequency control) let, overclocking capability of the PCIe 3.0 x16 bus and DMI bus chipset, upgrade / HIS, support for DDR4-2933 TIM memory etc.).
The uncore element remains virtually unchanged from the previous generation, and DDR4 and PCI Express 3.0 memory is supported.

At the heart of Comet Lake’s new design is the new monolithic 10-core processor matrix that remains structurally similar to the 8-core “Coffee Lake Refresh” array and the 4-core “Skylake” array.
The cores are located in two rows between the embedded graphics processor and the uncore element (system factor with image, memory, and I / O drivers), and all elements communicate and connect to each other through the ring bus hyperlink . The cache hierarchy has also not changed since the past, with the first tier being 32 KB for commands (L1I) and 32 KB for data (L1D), the second tier (L2) is 256 KB per core. and the third level to be shared by all the cores (shared cache L3) and have a size of 20 MB. IGPU is the same Intel UHD 630 based on Gen 9.5.
The key innovation, if we can call it that, in codec-named 10th generation Intel Core processors Comet Lake, is in the microprocessor of the processors and they are the boost algorithms.
The 10-core 20-wire array is the backbone of 10th-generation Core i9 processors, including the flagship Core i9-10900K that displays a maximum operating frequency of 5.3GHz with Intel claiming to be the fastest gaming processor .
This processor incorporates “graphics” and is unlocked. The Intel Core i9-10900KF is also unlocked, however it does not have an iGPU (i.e. it exists but is powered off). The Core i9-10900F has a locked multiplier and no built-in “graphics”. The prices of the previous processors (for quantities of 1000 pieces) range between $ 422 and $ 488.
The Core i7 processors are all eight-core and sixteen-thread (8-core / 16-thread) and have 16MB of L3 cache. At the top of the food chain is the Core i7-10700K with an operating frequency of 5.1GHz, while Intel also announced the Core i7-10700K, Core i7-10700KF, Core i7-10700, and Core i7-10700F.
The tenth-generation Core i5 is now a six-core (6-core / 12-thread) model and incorporates 12MB of shared L3 cache. The most powerful model is the Core i5-10600K followed by the Core i5-10600KF, Core i5-10600, Core i5-10500, Core i5-10400 and the latest Core i5-10400F. Its cost (for quantities of 1000 pieces) starts at $ 157 and reaches $ 262 for the unlocked Core i5-10600K.
All “unlocked” processor models, from Core i9 to Core i5, have TDP at 125W (!) And all other Core models are 65W. Pentium and Celeron have a TDP of 58W.
Core i3 series models have four cores (4 cores / 8 threads) with Core i3-10300 and Core i3-10320 models incorporating 8MB of shared L3 cache and Core i3-10100 model having 2MB less and cost $ 122 when the other two models cost $ 143 and $ 154 respectively (all Core i3 processors are “locked”). The Pentium Gold G6000 and Celeron G5900 series are at the lowest level and consist of dual core models. Pentium has four threads and 4MB of shared L3 cache, while Celeron processors remain with two threads and have 1MB less of shared L3 cache.
Along with the 10th generation of Core processors for desktop computers, Intel also announced the new series of support chipsets consisting of Intel B460, H410 and Z490, the latter being the richest and most capable. It is manufactured at 14nm and, in terms of connectivity, offers 24 PCI Express 3.0 lanes: in combination with the 16 lanes of the processor, we end up with a system with a total of 40 PCI Express 3.0 lanes, with motherboards that now integrate up to three M.2 NVMe slots, enough plus USB 3.2, Thunderbolt 3 controllers, etc.
The Intel Z490 also incorporates a 6-port 6Gbps AHCI / RAID SATA controller, a 4-port USB 3.2 Gen2 controller with Gen2 x 2 (20Gbps), up to 12 USB 3.2 Gen1 slots, HD audio with Intel smart sound, and It comes with either the i225-V “Foxville” 2.5 GbE controller or the i219-V “Jacksonville” 1 GbE. The new Intel processors and compatible motherboards will launch in May-June.
