Intel Core i5-9400F vs Intel Pentium Silver N6000 vs Intel Core i9-9900KS

Intel Core i5-9400F

Intel Pentium Silver N6000

The Intel Pentium Silver N6000 is a quad-core SoC of the Jasper Lake series that is primarily intended for inexpensive notebooks and was announced in early 2021. The four Tremont CPU cores clock between 1.1 and 3.3 GHz (single core Burst) and offer no HyperThreading (SMT). The N6000 uses 1.5 MB L2 and 4 MB L3 cache. The chip is manufactured on the first-gen 10 nm Intel process, the same process as Ice Lake.

Architecture

The processor architecture is called Tremont and a complete redesign compared to the old Golmont Plus cores in the predecessor. According to Intel, the single thread performance of a core could be improved by 30% on average (10 - 80% in all tests of SPECint and SPECfp).

Features

In addition to the four CPU cores, the SoC integrates a 32 EU Intel UHD Graphics GPU clocked from 350 - 850 MHz and a dual-channel DDR4 / quad-channel LPDDR4x memory controller (up to 16 GB and 2933 MHz). The chip now also partly integrates Wi-Fi 6 (Gig+), 8 PCIe 3.0 lanes, 14 USB 2.0/ 3.2 ports and two SATA 6.0 ports. The package got bigger and measures 35 x 24 mm (compared to 25 x 24 mm for the N5030 e.g.). The SoC is directly soldered to the mainboard (BGA) and can't be easily replaced.

Performance

The average N6000 in our database proves to be an OK entry-level processor, as of late 2022, its multi-thread benchmark scores nearly matching those of the AMD Ryzen 3 3200U. Yes, the chip is a whole lot slower than the latest Ryzen 3 and Core i3 processors, but it will at least let you run your day-to-day apps without annoying slowdowns.

The Asus Vivobook 13 Slate is among the fastest systems built around the N6000 that we know of, thanks to the long-term CPU power limit of 10 W. It can be more than 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

Like nearly all other N-class Intel processors, the Pentium N6000 has a default TDP of 6 W (also known as the long-term power limit). This is low and thus good enough for passively cooled tablets, laptops, mini-PCs.

The SoC is built with Intel's 2nd generation 10 nm process (not 10 nm SuperFin or Intel 7) for low, as of mid 2023, energy efficiency.

Intel Core i9-9900KS

The Intel Core i9-9900KS is a high end desktop processor that includes 8 cores based on the Coffee Lake architecture. It is the fastest Coffee Lake CPU in 2019 and compared to the similar named i9-9900K, the KS offers an all core Turbo of 5 GHz. All cores can clock between 4 GHz and 5 GHz and thanks to Hyperthreading / SMT 16 threads can be executed in parallel. The CPU is still manufactured in the mature 14 nm process (14nm++). Thanks to the open multiplicator, the CPU is rather easy to overclock (if a Z390 based mainboard is used).

With good cooling, the i9-9900KS can be around 10% faster than the older Intel Core i9-9900K (thanks to the 5 GHz all core Turbo). Compare to the old Core i7-8700K, the 9900KS is even 45% faster. Especially for gaming, the 9900KS is currently the fastest option available. The fast Ryzen and Threadripper CPUs from AMD however offer a better multithreaded performance.

The integrated GPU is called Intel UHD Graphics 630 and clocks with up to 1.2 GHz. It is not suited for demanding 3D games and located in the low end.

The TDP is raised to 127 Watt for the additional performance, therefore a good CPU cooler is needed. When overclocking the CPU, more than 200 Watt can be reached unter load.
