i9 13900K tested, 50% gain vs 12900K

i9 13900K tested, 50% gain vs 12900K

Yesterday at 7 pm Intel core i9 13900K performance leaked on Bilibili . page ECSM_Official In association with OneRaichu. In this test, ECSM announced the launch of Lake Raptor on September 28, 2022. This new batch of processors still etched at 10nm will be able to reach frequencies 500MHz higher than Alder Lake. Ecore is doubled and the L2/L3 cache is increased.

User test configuration

  • Processor 1: Intel Core i9 13900K
  • Processor 2: Intel Core i9 12900KF
  • DDR5-6000 CL30-38-38-76, DDR4-3600 CL17-19-19-39, Trefi = 262143, other settings = auto.
  • Motherboard: Z690 Taichi Razer Edition and Z790****
  • BIOS version: 12.01 and ****
  • Graphics Processor: AMD Radeon RX 6900 XTXH OC 2700 MHz
  • Cooling: NZXT Kraken X73

The i9 13900K’s frequencies have been tweaked up, as well as the cache.

For Backre we have:

  • 1-2C 58x / 3-8C 55x at 13900K
  • 1-2C 52x / 3-8C 49X on 12900K
  • 8x 2MB L2 for 13900K
  • 8x 1.25MB L2 for 12900K
  • L3 cache goes from 30MB to 36MB

Here we have an L2 cache increase, 6MB over 8 nuclei reunite them. With a 600MHz gain, that 13,900K risks bringing down the yet-to-be-released Ryzen 9 7950X.

For Ecore, we have:

  • 1-16C 43X at 13900 K
  • 1-4C 39x / 5-8C 37X at 12900K
  • 4x 4MB L2 for 13900K
  • 2x 2MB L2 for 12900K

As we can see, Ecore doubles its L2 cache per package of 4 Ecore, in total we have 4 times more cache on Ecore. Added to this is the 400-600MHz frequency gain and 8 Ecore gain, and here we have significant overall performance gains.

New configuration in cache

Unlike Alder Lake, Raptor Lake completely separates the loop frequency between Pcore and Ecore. As a result, the cache frequency can remain at 4.7 GHz without dropping to 3.6 GHz as in Alder Lake. Here we are talking about downgrading from 5GHz to 4.6GHz. So there will be no obvious access penalty when connecting between Ecore and Pcore.

As we can see, the latency between Pcore and Ecore goes from 33 to 37 ns to 31 to 34 ns. With a drop to less than 30 ns at the Pcore 8 connection (topic 14 and 15).

Lake Raptor vs. Alderlake performance

In this test, we have a lot of performance information, from AIDA to video games to Cinebench and 3DMark. As we’ll see, the 13,900,000 Lake Raptor offers a significant performance gain compared to the 12,900,000 Alderliks.

Aida 64

In AIDA64 we immediately notice an increase in L3 cache bandwidth. This is due to the new cache configuration. L2 and L1 caches gain productivity thanks to the high frequency of nuclei But at the expense of latency due to a larger cache. This increase in L2 cache also increases memory latency.

Cinebench and IPC

On cinebench we can see that the result single core It runs from 2020 to 2292 on the R23. in multicore We went from 27,682 to 40662, which is a 47% increase in multi-core performance.

If we go into the details, we can see that the CPI at equal frequency rises from 2.37% to 5.56% depending on the Standard.

On the 3D mark this time we have a gain of 20.81% to 45.8%. With a score of 25267 versus a 5.5GHz allcore, we’re far ahead of what the 5.5GHz 12900KS can offer with serious memory and CPU overclocking.


Now moving to CPU-Z, we have a gain of 14.5% on a single core and 49% on a multi-core compared to the 12900K.

7-Zip and Winrar

Another performance indicator here is 7-zip compression and decompression. Here we get 55.6% when decompressing and 15.2% when decompressing. Heterogeneous gains, it will be necessary to investigate with our test platforms to see if it comes from RAM.

performance summary

To wrap up this comparison 12900K vs 13900K, the summary table allows us to see the overall gain in multicore In any case Standards been tested.

We can see that the average profit is about 41.78%, when the maximum and minimum are 76.72% and 0.33%.

Boost in-game performance

We start with Counter Strike Global offensive, in high quality. Here the gain is 13.7% at 1080p with DDR5 and 11.8% with DDR4. Gains at 1440p of the same order

On Shadow of the Tomb Raider in high quality with TXAA. We had a gain of 7.3% in 1080p and DDR5, with DDR4 we had a gain of 8.15%. At 1440P, gains ranged from 0% to 1.06%, pretty low in and of themselves.

In Watch Dogs Legion in HD, the gain at 1440p is nothing. But we notice a gain of 4.7% to 3.26% at 1080p.

We end this tour with Far cry 6, in high quality. Here the gain at 1080p ranges from 3.9% with DDR4 to 4.06% with DDR4. At 1440p, the gain hovers around 0.06%, which is zero gain in itself.

Our first view on this 13900K

Needless to say, the Intel Core i9 13900K processor is a performance beast. It is able to hold a frequency of 5.5GHz out of the box. Where the 12900KS, which is very good, struggles to do just by overclocking. Add to that the frequency gain on Ecore and the gain of 8 Ecore and we have the Ryzen 9 7950X Killer.

In terms of temperatures, we don’t have a lot of information, but during this test the 13900K ran under a simple NZXT AIO Z73. And with 343W consumed at 1.4V under heavy load on the Cinebench R23, the latter didn’t throttle.

Looking forward to getting copies to see how far they can be taken. Our community also expects a lot, especially with regards to 3DMark.
