[REVIEW] : Intel’s Core i9-13900K Raptor Lake with 24 cores and 32 threads previewed on a benchmark.
At Intel, the processors of the moment are part of the Alder Lake range launched only three months ago. However, the American founder is obviously working on the sequel, the Raptor Lake generation, which should be released before the end of 2022.
Already at the level of the Core i9-12900K
The beefiest of the processors in this new range, the Core i9-13900K has already been seen several times, through various more or less serious leaks. The latest one is interesting in that it focuses on a bench well known to testers.
Indeed, relayed by WCCFTech, said leak focuses on the video game Ashes of the Singularity. Through its database, we discover the first measurements of a Core i9-13900K supported by 32 GB of RAM and an NVIDIA GeForce RTX 3090 graphics card.
On the test, it obtained a result of 134.9 frames per second, which puts it ahead of the Ryzen 9 5950X (~116 fps), but above all on the same level as the Core i9-12900K (~133 fps). Remember that the Core i9-13900K is still only an engineering sample and, in this sense, it is far from representing the final version of the CPU, of its BIOS.
Double the number of Gracemont cores
Intel still has several months to optimize things and improve the performance of a processor that stands out from the outset by increasing the number of efficient cores, the “small” Gracemont. Eight in number on the beefiest Alder Lake CPU, there will be 16 on the Core i9-13900K.
This doubling should also be found on the other CPUs in the Raptor Lake range, at least the “K” series. Thus, the Core i7-13700K and Core i5-13600K will integrate 8 while their predecessors, the Core i7-12700K / Core i5-12600K only have 4.
If these efficient cores will always be Gracemont, the Raptor Lake range will trade its high-performance Golden Cove cores for Raptor Cove. There is also talk of an increase in the cache associated with these CPUs: 68 MB against 30 MB for the Core i9-13900K vs. the Core i9-12900K, 54 MB against 25 MB for the Core i7-13700K vs. the Core i7-12700K and 44 MB against 20 MB for the Core i5-13600K vs. the Core i5-12600K.
Finally, while we still have a lot to learn about Raptor Lake, there has already been talk of improving RAM support. We would effectively switch to official support for DDR5-5600 against DDR5-4800 on Alder Lake.
The Core i9-13900K already impresses under Ashes of The Singularity
Intel’s next showcase, the Core i9-13900K makes its entry into the Ashes of The Singularity benchmark database. This processor is part of the 13th generation Core line aka Raptor Lake.
This reference has been the target of several leaks for the past few weeks. It is now almost confirmed that its architecture will offer up to 32 threads. The new entry in the Ashes of The Singularity database once again confirms this. On the other hand, the application cannot differentiate the physical cores from the logical cores due to a hybrid design of the chip. Like Alder Lake, this Core i9-13900K will be equipped with P-Core and E-Core.
On this subject we mentioned a mechanism with 24 physical cores (8 + 16) and capable of managing 32 threads. The set benefits from an engraving at 7 nm while the P-Core and E-Core are based on improved versions of the existing one. Adding more E-Cores to the current Core i9-12900K should boost multi-core performance. Intel is also supposed to increase the cache to 68MB to optimize gaming prowess. It will be a kind of “gaming cache”, a response to AMD’s famous 3D V-Cache. The firm with its Ryzen 7 5800X3D supported by 96 MB announces that it exceeds the performance of the Core i9-12900K by up to 10%.
With the Core i9-13900K and its doubled cache, Intel should erase AMD’s lead while taking control by playing on frequencies. The upgraded P-Cores will be clocked at up to 5.3GHz+. So it is possible that Intel can already position itself against Zen 4.
Core Raptor Lake-S processors
According to the leaks, the 13th generation Cores will organize around three offers. We will have the “K” references with an unlocked multiplier coefficient and a thermal envelope of 125 Watts, the references with a TDP of 65 Watts and the so-called “low consumption” models with a TDP of 35 Watts.
The architecture will offer 24 cores, 16 cores, 10 cores, 4 cores and 2 physical cores. Each Raptor Cove core is said to carry 2MB L2 cache and 3MB L3 cache while Gracemont will carry 4MB L2 cache and 3MB L3 cache. Thus it is speculated the following offer
- Core i9 K-Series (8 P-Cores + 16 E-Cores) = 24 cores / 32 threads / 68 MB,
- Core i7 K-Series (8 P-Cores + 8 P-Cores) = 16 cores / 24 threads / 54 MB,
- Core i5 K-Series (6 P-Cores + 8 P-Cores) = 14 cores / 20 threads / 44 MB,
- Core i5 S-Series (6 P-Cores + 4 P-Cores) = 14 cores / 16 threads / 37 MB,
- Core i3 S-Series (4 P-Cores) = 4 cores / 8 threads / 20 MB,
Intel Core i9-13900K: here is a first “useless” benchmark in video games
Very often before the release of a new generation of CPUs and even GPUs, we are entitled to performance leaks under certain benchmarks. The video game Ashes of the Singularity is one of those benchmarks that often give us leaks before a launch. Indeed, if we are not careful, the sending game sends the benchmark to the database accessible to the public. Today, it’s the processor Intel Core i9-13900K who goes there.
A benchmark which, in fact, does not tell us much
This processor from Intel uses 24 cores and 32 threads. To be more specific, we have 8 P-Cores (high performance cores codenamed Raptor Cove) and 16 E-Cores (high power efficiency codenamed Gracemont). According to the latest rumors, these hearts could be accompanied with up to 68 MB of cache memory, an iGPU with 32 execution units (256 cores). All with a TDP of 125W .
To get to the point, in this benchmark the processor is accompanied by 32 GB of memory and an NVIDIA GeForce RTX 3090 graphics card. On the other hand, the scores are at the same level as the current i9-12900K. But this is actually an engineering sample. Which means that it can run at reduced frequencies (unknown here), basically it still lacks optimization. Note also that the name of the processor is not recognized and it is only mentioned Genuine Intel(R) 0000. Don’t be fooled by the 32 “Logical” cores. This is an AotS read error where for example an i9-12900H is read with 20 logical cores. In short, little doubt that it is indeed an i9-13900K.
