Specifications
The i9-13900 (Non-K) is similar to its K counterpart in terms of core and thread count. The CPU features 24 cores (8p + 16e) along with 32 threads. However, the main difference lies in the TDP(s).
i9-13900 (Nominal : 65W) (Max Turbo Power : 200W)i9-13900K (PL1: 125W) (PL2: 250W+) (Extreme Power Mode : 350W+)
Here PL stands for Power Limit and the ‘Extreme Power Mode’ consuming more than 350W of power will only be enabled on select 700-series motherboards from Intel.
Test Bench
Over at Geekbench5, we came across a benchmark featuring Intel’s i9-13900 paired with a GIGABYTE Z690 GAMING X motherboard. 32GB of DDR5 memory has been used for this test. The CPU’s base frequency is listed as 2.0GHz. When the CPU reaches higher clock speeds (Intel Turbo Boost), the 65W TDP (PL1) is disregarded and you should keep the PL2 (200W) in mind for the power consumption.
The Performance
The CPU scores 2130 points and 20131 points in the single and multi core test respectively. This is really impressive for a CPU that consumes less power than its -K counterpart. The CPU pulls ahead of the i9-12900K by around 7.46% in single core testing. The i9-13900 stands out well between other CPUs from Raptor Lake, slightly edging them out in efficiency. Moving on to multi-core performance, we see a massive bottleneck due to the lower power consumption (65W-200W). The CPU still remains 17.7% faster than even the R9 5950X, however, it falls extremely short of the full power the microarchitecture has to offer. The numbers speak for themself:
Expectations
Intel’s Raptor Lake outperforms AMD’s upcoming offerings in single-core testing as unveiled here. However, team red may pull ahead in multi-core once more. It is still unclear how AMD’s Zen4 will perform against Raptor Lake aside from synthetic benchmarks. However, we can expect more information from AMD on the 29th of August where an official announcement regarding Ryzen 7000 will be made.
