Windows 11 gives Intel Core i9-12900K exclusive boost in benchmark comparison but the Alder Lake chip still lags behind the AMD Ryzen 9 5900X
More synthetic benchmarks featuring the Intel Core i9-12900K have turned up, and while some of them are difficult to find credible, this particular believable leak offers up some good news and bad news for Team Blue. Once again, data-miner APISAK has been digging out information from SiSoftware and has come up with performance results for the 16-core (8C+8c) Alder Lake chip when running on Windows 11. We already reported about the rollercoaster performance the i9-12900K made against the i9-11900K and Ryzen 9 5900X on this particular benchmark, but it seems Microsoft has delivered on its promise to give Alder Lake a boost on Windows 11.
In the Vector SIMD Native tests, the i9-12900K produces scores that are generally around 10% greater on Windows 11 than Windows 10, with one test being quite a bit lower, one being a bit higher, and one with negligible difference. These are the apparent performance gains for each test:
| SIMD test | Windows 10 | Windows 11 | Difference |
|---|---|---|---|
| Quad Float | 50.94 | 53.07 | +4.18% |
| Double Float | 979.66 | 1,097.06 | +11.98% |
| Single Float | 1,706.60 | 1,958.74 | +14.77% |
| Quad Int | 119.56 | 131.13 | +9.68% |
| Long | 626.95 | 691.90 | +10.36% |
| Integer | 1,691.01 | 1,691.13 | +0.007% |
It is a markedly better performance for the Intel Core i9-12900K and shows just how important Microsoft’s new operating system will be when the time comes for Intel to promote its Alder Lake (ADL) processors. However, while some benchmarks have been showing the i9-12900K blowing all competitors out of the water, including the Zen 3 family from AMD, there is a different story found here. Despite the gains made in Windows 11 over Windows 10, the 12th Gen Intel CPU still cannot overtake the 12-core Ryzen 9 5900X in the majority of the individual tests:
| SIMD test | Intel Core i9-12900K (Windows 11) |
AMD Ryzen 9 5900X (Windows 10) |
Performance difference |
|---|---|---|---|
| Quad Float | 53.07 | 49.47 | +7.28% for ADL |
| Double Float | 1,097.06 | 1,190 | +8.47% for Zen 3 |
| Single Float | 1,958.74 | 2,000 | +2.11% for Zen 3 |
| Quad Int | 131.13 | 157 | +19.73% for Zen 3 |
| Long | 691.90 | 805 | +16.35% for Zen 3 |
| Integer | 1,691.13 | 2,000 | +18.26% for Zen 3 |
So while the good news for Intel is that Alder Lake can seemingly produce higher scores on Windows 11 thanks to the operating system's optimizations for the hybrid chip family's big.LITTLE core architecture, the bad news is that the 12th Gen flagship processor cannot overtake the enthusiast-level Zen 3 part from AMD, which was released in November 2020.
