Intel Celeron 6305 vs Intel Core i9-9900KS

Intel Celeron 6305

The Intel Celeron 6305 (or 6305U) is a power efficient dual-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced in the third quarter of 2020. It integrates only two Willow Cove processor cores (2 threads - no Hyper-Threading/SMT). The clock speed is set at 1.8 GHz as the chip does not support Turbo Boost.

Performance

The average 6305 in our database is in the same league as the Celeron N4505, as far as multi-thread benchmark scores are concerned. This is a very poor result, as of late 2022.

Your mileage may vary depending on how high the CPU power limits are.

Another novelty is the integrated Xe graphics фвфзеук based on the completely new Gen 12 architecture. It should offer a significantly higher performance compared to the older UHD Graphics G1 (Ice Lake). In the 6305U Intel calls it just UHD Graphics and it offers 48 EUs.

Other improvements from Ice Lake should be also integrated in Tiger Lake like the AI hardware acceleration and the partial integration of Thunderbolt and Wifi 6 in the chip.

The chip is produced on the improved 10nm+ process (called 10 nm SuperFin) at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).

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.
