Intel Core i9-9900K 8 Core/16 Thread, Core i7-9700K 8 Core/8 Thread and Core i5-9600K 6 Core/6 Thread CPU Single Core and Multi-Core Performance Leaks Out

Not one, not two but the performance numbers of all three of Intel's upcoming 9th generation unlocked processors has leaked out. The performance numbers are compiled in Geekbench 4 which shows what kind of jump we should expect from the core count bump on the high-end processors, arriving next month.

Intel Core i9-9900K, Core i7-9700K, and Core i5-9600K Unlocked 9th Gen CPU Performance Leaks Out in Geekbench

All processors seem to have been tested on stock clock speeds which are very high out of the box. We are talking about up to 5.0 GHz boost on a single and up to 4.7 GHz boost on 8 cores. Here we can see that the enhanced 14nm++ process node is really helping Intel deliver the fastest clocked mainstream processors to date and even though there aren't any architectural improvements to talk about, the core jump and clock speeds would really help boost performance in gaming, multi-tasking and rendering workloads.

Intel Core i5-13600K, Core i5-13500, Core i5-13400 CPU Benchmarks Leak Out, Faster Than 12600K In $170-$200 US Price Range

Starting with the flagship part, the Intel Core i9-9900K scored 6248 points in single core and 33037 points in multi-core benchmarks. These are some of the highest numbers we have seen for an LGA 1151 socketed mainstream part and nothing even from the rivaling Ryzen club comes close to this. The chip was tested on an ASUS ROG Maximus X HERO motherboard with 16 GB of DDR4 memory which is pretty standard but what I am really interested to see now is where overclocks would take this score to since all three unlocked SKUs will be rocking a soldered IHS design and that would be a lot of help in keeping the chip cooler when overclocked and even when running under stock load.


The Intel Core i7-9700K scored 6297 points in the single core and 30152 points in the multi-core benchmark. While the single core score is similar to the Core i9-9900K since there's a difference only of 100 MHz, the lower threads on the 9700K resulted in 3000 points lower than the flagship. The chip was tested on a Gigabyte Z370 AORUS Ultra Gaming motherboard. Comparing it to the Ryzen 7 2700X shows that the chip is much faster in single core workloads but the Ryzen 2700X has a total of 16 threads while the Core i7-9700K has only 8 threads so while the 9th Gen chip is in lead, the difference in performance is lower than the 8700K’s multi-core score.


The last part that was tested is the Intel Core i5-9600K which was also tested on a similar config as the Core i7-9700K. The chip scored 6027 points in single core and 23472 points in multi-core CPU benchmark. Here, we also see the single core performance just about the same as the other parts but multi-core performance is lower due to much lower threads. The Core i5-9600K is an i5-8600K on steroids based on the clock speeds. The 8600K itself scored around 5000 points in single core and 19000-20000 points in multi-core benchmark so we can see a good boost in performance for this part.

Intel Core i9-9900K, Intel’s First 8 Core Mainstream CPU With 4.7 GHz All 8 Core Boost Frequency, Faster Than Intel’s 8086K Anniversary Edition In All Possible Ways

First up, we will detail the flagship part, the 8 core, 16 thread, Intel Core i9-9900K. This will be the first mainstream desktop Core i9 part and also the first Intel chip to boast 8 cores and 16 threads. In terms of cache, the chip will feature 16 MB of L3 and will come with an Intel UHD 620 graphics chip.

The clock speeds are something to check out here, we are going to get a 3.6 GHz base clock out of the box and a 5.0 GHz boost clock in single and dual core operations. 4 core boost is rated at 4.8 GHz while 6/8 core boost is rated at 4.7 GHz. This is the highest frequency we have seen on an 8 core part across all cores. All of this is done under a 95W package so we can expect some hefty cooling solutions to go along with this chip.

Intel Core i7-9700K, Intel’s First 8 Core, Core i7 Mainstream Desktop CPU With Up To 4.6 GHz Clocks Across All Cores

Coming to the top Core i7 part, we get 8 cores and 8 threads. This the complete opposite of what we have been hearing as previous rumors identified the chip as a 6 core and 12 thread part. The chip will have 12 MB of L3 cache and as you might tell, it has lower threads than the Core i7-8700K but comes with higher core count. So maybe, we will get same or even better performance from the chip.

In terms of clock speeds, the chip has a base clock of 3.6 GHz and boosts up to 4.9 GHz in single, 4.8 GHz in dual-core, 4.7 GHz in four core and 4.6 GHz in 6/8 core operations. The TDP for this part is maintained at the same 95W.

Intel Core i5-9600K, 6 Cores, and 6 Threads With Higher Clocks Than 8th Generation i5 ‘K” SKU

The Intel Core i5-9600K is a 6 core and 6 thread part with 9 MB of L3 cache. This makes it very similar to the Core i5-8600K. The difference is that it features higher clock speeds of 3.7 GHz base, 4.6 GHz boost (1 core), 4.5 GHz (2 core), 4.4 GHz (4 core) and 4.3 GHz (6 core). All of this is done at the same TDP of 95W.

The 9th generation will be compatible with existing 300 series and the new Z390 motherboards. Following are some key features of the upcoming lineup:

  • First performance Intel Core i9 desktop s-series processor
  • Up to 8 cores
  • Intel Z390 chipset compatible
  • Solder Thermal Interface Material (STIM)
  • Integrated USB 3.1 gen 2 and Integrated Intel Wireless-AC
  • Up to 16 threads, 5.0 GHz, 16 MB cache, and 40 platform PCIe lanes (16 CPU + 24 PCH)
  • Compatible with all Intel 300 series chipsets
  • Intel Optane memory and Intel Optane SSD support
  • Thunderbolt 3 support

The specifications have been listed but there's currently no word on the prices which are said to be expected around September, around the same time as the official announcement. Expect more on details regarding the prices and performance of these new 6 and 8 core mainstream parts from Intel in the coming months.
