Intel Core i9-10900KF Beats AMD Ryzen 9 3900X With 10th Gen 10 Core Configuration On 14nm Fabrication Node?

A new set of benchmarking results of the 10 Core Intel Core i9-10900KF has surfaced online. The desktop-grade 10th Gen Intel CPU sports the ‘KF’ suffix which indicates it is meant for desktops that will rely on dedicated Graphics Card. Although the onboard iGPU on the 10 Core Intel CPU will be disabled, it will have identical specifications to the 10th Generation flagship, the Core i9-10900K.

Intel is readying multiple variants of the 10th Gen Core i9-10900 desktop-grade CPU. The latest variant to leak online is the Intel Core i9-10900KF, which is essentially the Core i9-10900K with the embedded iGPU disabled. The latest flagship from Intel is still being manufactured on the archaic 14nm Fabrication Node. This means the Intel’s flagship Core i9-10900KF is a Comet Lake-S variant with 10 Cores and is headed to the desktop PC.

Benchmark Results Of Intel Core i9-10900KF CPU Indicate Strong Competition To AMD Ryzen 9 3900X But Power And Thermals Remain A Concern?

The latest leaked benchmarks indicate the Intel Core i9-10900KF scores 12,412 points in the 3DMark Time Spy benchmark. It is marginally lower than 13,142 points scored by the Intel Core i9-10900K. However, the testbench of the Intel Core i9-10900KF featured 16 GB (2x8GB) of DDR4-2400 MHz memory whereas the Intel Core i9-10900K configuration comprised of 64 GB (4x16GB) of DDR4-2666 MHz memory.

Although the amount of RAM doesn’t make much difference, the bandwidth of the same could be responsible for the difference in scores. Interestingly, with 32 GB (2x16GB) of DDR4-3200 MHz memory, the AMD Ryzen 9 3900X 12 core CPU managed to score 12,857 points. The comparative scores of all the test benches are as below:

  • AMD Ryzen 9 3900X (DDR4-3800 / 32 GB) – 13,650
  • AMD Ryzen 9 3900X (DDR4-3400 / 32 GB) – 13,193
  • Intel Core i9-10900K (DDR4-2666 / 64 GB) – 13,142
  • AMD Ryzen 9 3900X (DDR4-3200 / 32 GB) – 12,857
  • Intel Core i9-10900KF (DDR4-2400 / 16 GB) – 12,412

It is interesting to note the significant difference in memory configurations. However, paired with proper memory, the deca-core Intel Core i9-10900K/KF chips could match or even outpace the 12 core AMD Ryzen 9 3900X. This is because Intel CPUs tend to support much higher frequency RAM. If the reports are accurate and Intel has finalized the finetuning, then the latest Intel flagship is a true competitor to the 7nm AMD Ryzen 9 3900X despite being manufactured on the 14nm Fabrication Node.

10 Cores 20 Threads 10th Gen 14nm Comet Lake Intel Core i9-10900K/KF Specifications, Features, Price, And Availability:

Just like its cousin, the Intel Core i9-10900KF features 10 cores and 20 threads. It will feature a base clock of 3.70 GHz and a boost clock 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. Moreover, the Intel flagship sports a 4.9 GHz all-core boost.

The 10th Gen 14nm Comet Lake Intel Core i9-10900KF carries 16 MB of L3 cache & 4 MB of L2 cache, rounding up for a total of 20 MB of cache. The package TDP at PL1 (base clock) is rated at 125W. While this itself is on the higher side when compared to AMD’s counterparts, the PL2 or boost state where the chip would be averaging around could cross the 300W TDP barrier.


The thermals of the 10th Gen 14nm Comet Lake Intel Core i9-10900KF are certainly a cause of concern. This would certainly mandate motherboard makers to take extra precautions while making boards that will be compatible with the 10th Gen Intel flagship.

Coming to the price of the Intel Core i9-10900KF, experts indicate Intel could price the same at between $400 and $500. The company could time the launch and commercial availability to coincide with the holiday season.
