Upcoming Intel Core i9-12900K beats AMD Ryzen 9 5950X easily according to the latest leak


The Intel Alder Lake is expected to officially launch aroubd the fourth quater of 2021. Alder Lake will be established on a 10 nm Enhanced SuperFin process, now known as Intel 7. With the launch around the corner a few leaks of Alder Lake processors have emerged on several benchmarking sites. The latest is the Geekbench 5 entry of the flagship Core i9-12900K processor.


Intel traditionally brandished the single-core feat crown while AMD excelled in multi-core. With the launch of Zen 3, AMD finally closed this single-core gap. Though Intel did survive to wrestle away the single-core leads from Zen 3 once again with Rocket Lake, multi-core was still AMD's forte given that the Core i9-11900K was limited at eight cores. Rocket Lake's single-core gains nevertheless entered at the cost of increased power consumption. This may differ when Alder Lake launches later this year.


The Core i9-12900K proposes an eight Performance Cores and eight Efficient Cores, which provides it a 16C/24T configuration. According to the Geekbench leak, the Core i9-12900K scores 1,893 and 17,299 in single-core and multi-core, respectively. Leaker @TUM_APISAK on Twitter spotted another such entry indicating 1,834 and 17,370 points. For a timely preliminary comparison, we can thus contemplate the average scores as 1,863.5 and 17,334.5.



Taking the average Geekbench 5.3 scores for a Core i9-11900K at 1,815 and 10,742 and for a Ryzen 9 5950X at 1,652 and 16,248, we find at the Alder Lake Core i9-12900K is about 2.7% and 61.3% faster than the Rocket Lake Core i9-11900K and about 12.8% and 6.7% faster than the Zen 3 Ryzen 9 5950X in single-core and multi-core tests, respectively.


The Geekbench record seems to be documenting the clocks mistakenly, the Core i9-12900K might offer up to 5.3 GHz single-core turbo and a 5 GHz all-core boost on the Performance Cores while the Efficiency Cores are likely to offer 3.9 GHz single 3.7 GHz all-core boosts.


The test bench is demonstrated as running Windows 11 Pro, which is not surprising since registering developments in Microsoft's upcoming OS looks to benefit heterogeneous ISAs such as Alder Lake compared to what Windows 10 can. Alder Lake will also bring support for DDR5 memory and the test bench here seems to be using 32 GB of DDR5 memory conforming to DDR5-4800 JEDEC B timings as referenced by the .gb5 raw data from the benchmark.
