Intel Core i9-13900 Performance Preview - 50% Faster Than Core i9-12900 ?

A performance preview of Intel Core i9-13900 with 24-cores has been published by SiSoftware & Intel Core i9-13900 test results emerge

Intel Core i9-13900 ‘Raptor Lake’ Early CPU Sample Tested, Up To 50% Faster Than Core i9-12900 ‘Alder Lake’ at Just 3.7 GHz Clock Speeds

Once more intel's Raptor Lake Desktop CPUs send off in the not-so-distant future to handle AMD's Zen 4 'Raphael' set up and it seems as though SiSoftware has figured out how to distribute a smaller than expected survey of a Core i9-13900 CPU with 24 centres and 32 strings in an early designing state against Intel's Alder Lake and AMD Zen 3 chips.

Intel Raptor Lake Core i9-13900 ES CPU Up To half Faster Than Alder Lake Core i9-12900 At a Low Clock Speed of 3.7 GHz
The thirteenth Gen Intel Raptor Lake CPUs will brush the new Raptor Cove P-Cores and Gracemont (E-Cores) in a streamlined 10nm (Intel 7+) bundle. Contrasted with Intel's Alder Lake CPUs, the Raptor Lake chips will accompany a large group of upgrades other than additional centres and clock speeds. These include:

  • Support for up to DDR5-5600 memory (JEDEC)
  • 20% Larger L3 cache (Up To 36 MB Unified)
  • 2x Larger L2 cache (Up To 32 MB)
  • Support For AVX/AVX2 on E-Cores
  • No Support For AVX-512 (Just Like Alder Lake-S)

The Raptor Lake CPU sample tested is an Intel Core i9-13900 which features 8 P-Cores and 16 E-Cores for a total of 24 cores and 32 threads. The chip was running at max clock speeds of 3.7 GHz for the P-Cores and 2.76 GHz for the E-Cores. That's really low from the retail version which will be offering over 5.5 GHz speeds as mentioned in various leaks. The CPU is equipped with 32 MB of L2 cache (8 x 2 MB for P-Cores / 4 x 4 MB for E-Cores) and 36 MB of L3 cache for a combined total of 68 MB of 'Gaming' cache.

Coming to the benchmarks, it isn't referenced what careful test arrangement was utilized and assuming that the memory was for sure running at DDR5-5600 velocities. However, so, the outcomes are exceptionally amazing for an ES chip with such low clock speeds. The Intel Core i9-13900 'Raptor Lake' CPU presented to half elevate over the Intel Core i9-12900 in Whetstone FP32 tests and a great 2x addition in the FP64 tests. The chip wound up quicker than both, the Intel Core i9-12900 and AMD Ryzen 9 5900X which is really great for the impending arrangement.

The results above were with non-SIMD code so entering the SIMD workload segment, the overall performance takes a hit and we see the Intel Raptor Lake Core i9-13900 CPU ending up just 4-6% faster than Alder Lake. The Intel Core i9-11900K does deliver better performance thanks to its AVX-512 capabilities that are missing from Alder Lake & Raptor Lake CPUs. AMD also shows a huge lead here and with AVX-512 coming to Zen 4 CPUs, they can end up having a big lead over Raptor Lake in this particular segment.

A preview of the upcoming Intel 13th Gen Core CPU called Core i9-13900 has been published over By SiSoftware.

One ought to take note of that this is certainly not an ordinary survey in light of genuine equipment testing, yet rather, a collection of existing outcomes in the SiSoftware Sandra data set. Subsequently, it ought to be viewed as an outline of the forthcoming design with components of real execution testing.

Intel Core i9-13900 is a 24-center processor with 8 Performance and 16 Efficient centers. As per the SiSoftware, this processor series depends on a refreshed Intel 7+ cycle innovation, has 20% bigger L3 reserve and supports quicker DDR5 memory up to 5600 MT/s (up from 4800 MT/s on Alder Lake).

Moreover, L2 reserve has been improved for Raptor Lake, presently two times as large for Performance and Efficient centers (2MB per center for enormous center and 4MB per group of 4 centers on little centers). What is currently missing on Raptor Lake silicon is AVX-512 help presently totally handicapped (or not even present) on the silicon.

In test ALU/FPU test results collected by the author of this preview an overall 33% to 50% improvement over Alder Lake is demonstrated. Notably, that’s with lower clock speeds: Raptor Lake at 3.7 GHz P-Core & 2.76 GHz E-Core vs Alder Lake at 5.0 GHz P-Core & 3.8 GHz E-Core. Meanwhile, vectorized/SIMD tests confirm 5% to 8% better performance than Alder Lake.

Intel 13th Gen Core desktop processors should launch in a few months time. Various sources claim it is either ‘a month before‘ NVIDIA GeForce RTX 40 series (so possibly in August) or October.
