Intel Raptor Lake ES CPU was tested three months before launch

The details about the tests are obtained from a leaked screenshot from an Expreview video published on the Bilibili platform.

The website went on to test without wasting time after they got their hands on a sample of Intel’s upcoming 13th Gen Core Raptor Lake processor. With the model being clocked lower than any retail Alder Lake processor, the thing to be noted here is that this processor is an engineering sample. Keeping it in view, Expreview is putting on this Raptor Lake CPU in a test against the Alder Lake at the same frequency, which is almost 3800 MHz Turbo Boost for Performance cores. For the details, the sample is a Q0D8, recognized as ES1 (early engineering sample).

According to the leaked information, with the big core called the Raptor Cove and the Efficient heart being the same Gracemont architecture as seen on the Alder Lake silicon, the obtained sample packs in 8 Performance cores and 16 Efficient cores. Having an increase of 6MB compared to Core i9-12900K with which it competes, this sample features a total of 36 MB cache.

With prefatory clock speeds that will almost hit the same height as a retail version, this i9-13900 processor certainly packs in a lot of value. With the values as noted, one pack of the E-Cores runs at 1.0 GHz and the other at 2.0 GHz, and in addition, the P-cores are running at a whopping 1.4 GHz to 3.8 GHz range. Looking at the results, Wccftech noted that there is, therefore, some inconsistency in frequencies.

Packing 32GB of DDR5-memory running at 2600 MHz (5200 MT/s), Expreview gave the processor a go on the ASUS ROG Maximus Z690 EXTREME motherboard. Although it already appears to be supported, the motherboard BIOS is not optimized for this processor. It points to the fact that the motherboards of the individual systems need to be upgraded too to have a go with the latest version.

We noted that the single-threaded performance is lowered by ~10% when the sample is tested in the most popular CPU tests, Cinebench R20 and R23. On the other hand, along with the lowered value, the multi-threaded workload is 25% faster. It also points out the inconsistency that must be worked on to make it go much better than what is already there.

With all of the results being there by the increase in the number of cores, Expreview also concluded the processor shows a 20% increase over Alder Lake (including single and multi-threaded workloads).

Unfortunately, the Raptor Lake CPUs were slower in almost every game when the site tested it in gaming at 1080p resolution. On the contrary, the main difference is with the margin of error. However, the final result is that the Alder Lake CPU is faster every time. As Raptor Lake will be a recent launch of Intel, Intel will surely need to work a lot before making its appearance on the market, and they surely will make it happen for its consumers to have the best experience.
