SiSoftware
We are getting closer and closer to the debut on the market of the 12th generation Intel processors, known by the code name Alder Lake, and, as usual, we are witnessing a continuous leak of information from the most disparate sources, especially from the main software of benchmark.Credit: SiSoftware / TUM_APISAK Recently, the results of some tests have appeared in the SiSoftware online database, as reported by the well-known @TUM_APISAK, carried out on the Intel Core i9-12900K CPU, the top model of the next series. of processors of the company of Santa Clara. The chip, according to the latest information, is expected to handle sixteen cores in total, including eight high-performance Golden Cove and eight energy-efficient Gracemont. Other 125W chip specs include 30MB L3 cache, a 3.2GHz base clock, and a 5.2GHz boost clock. examination, therefore we advise you to consider the results reported as not definitive. The tests were conducted in three categories (Vector SIMD Native, Cryptographic Native and Financial Analysis Native), although they were not carried out in full form. Unlike other previously leaked benchmarks, the Core i9-12900K does not seem to score a landslide victory over the AMD Ryzen 9 5900X competitor in some tests, so much so that it is even beaten by the Core i9-11900K. It should be noted that the Core i9-11900K uses AVX512 where supported, which gives it a performance advantage over other CPUs in several tests.

SiSoftware compiles Intel Core i9-12900K performance preview
SiSoftware is well known in PC enthusiast circles for its synthetic benchmark and system information software. We have seen plenty of hardware leaks in the past when developers and engineers test unreleased products, and they pop up in the SiSoft online database. This weekend SiSoftware did something a bit different, it decided to compile its own tables and charts of an unreleased processor performance and write a blog post about its findings. Either there has been an internal rethink or an external elbow poke in the last few hours, as the blog/charts have all been removed from the SiSoft website.
Tum Apiksak was one of the first Twitter sources to load up and alert PC enthusiasts about the SiSoftware blog, sharing one of the key charts from it on Saturday. Later the same day, Apisak captured the whole blog post and squirrelled it away on Imgur. That is probably something PC hardware detectives do all the time, as this kind of sensitive info often gets zapped at source. If you prefer, you can also access the since deleted blog post via the Way Back Machine.
SiSoft's blog starts with an overview of the architectural changes resulting in Alder Lake, and then goes through the supported instruction sets for the big and LITTLE cores. It reminds readers that AVX512 is no longer supported on the P cores, but the E cores enjoy the uplift of AVX2 support. SiSoft Sandra has been updated with 'extensive changes to both detection, thread scheduling and benchmarks to support hybrid/big-LITTLE,' so it can even give you a good performance preview on pre-Windows 11 OSes.
In Sandra 20/21 Vector SIMD Native tests, the AMD Ryzen 9 5900X in Sandra's databases was a clear winner compared to the Intel Core i9-12900K. Actually, it looks inferior to the Core i9-11900K in these tests too. Looking through the other charts, it becomes clear SiSoft doesn't really have enough data to fill out its comparison tables, which it admits in the blog conclusion. A key assertion that it makes is that 'ADL has been designed for efficiency – not performance at any cost regardless of power usage (like RKL); it is perhaps too much to expect it to beat RKL in everything.' Nevertheless, in non-SIMD tests it says that ADL can be 25-50 per cent faster than RKL and be competitive with AMD Zen 3 (5900X).
SiSoft says Intel will be still working on optimisations compared to the processors we see in its databases. Moreover, the ADL performance data comes from various sources and various system configurations (motherboard, RAM, storage) so it is hard to be confident it will be representative because of this. We might even be seeing some tests on Windows 11, others on 10.
CPU-Z benchmark tests
While we are on the topic of ADL benchmarks, VideoCardz has found an Intel Core i9-12900K CPU-Z built-in benchmark score, as shared on Bilibili. This leak appears to show particularly strong performance for the ADL part.
As you can see above, the ADL part (apparently an Intel Core i9-12900K) got a 1T score of 825, and an nT score of 11906. These are good scores, with the new Intel ADL chip being 27 per cent faster than an AMD Ryzen 9 5950X (scores 648). In multicore nT tests the Intel (16C/24T) and AMD (16T/32T) CPU foes appear to be at level pegging.
Clearly these leaks are rather all over the place, but interesting nevertheless. Rest assured, HEXUS will be here with full coverage of the launch and publish our ADL reviews as soon as possible. Intel is expected to launch ADL-S in late October, with a November release.
