Preview of Core i9-13900 technical sample performance looks promising

In brief: Intel’s Raptor Lake processor lineup is still in the oven, but expectations around it are growing as we get closer to launch. According to an early preview, Team Blue’s 13th-generation processors could offer AMD’s Ryzen 7000 series some serious competition in terms of performance.

Details were scarce around Raptor Lake – Intel’s latest architecture built on the Intel 7 process node. Earlier this year, the company announced that its 13th-generation processors would offer an “up to double-digit performance increase” compared to Alder Lake.

The Raptor Lake series will come in 24 cores (eight performance cores and 16 efficiency cores) and 32 threads, and there is a slim chance that it will be compatible with DDR4 memory in addition to DDR5. Recently, SiSoftware released a preview of what to expect from the upcoming Core i9-13900 Raptor Lake-S CPU, although it should be noted that it is not a typical assessment of actual hardware, but rather an analysis of public data from the SiSoftware database. .

Like Alder Lake-S, Raptor Lake-S does not support AVX-512 instructions, but it is unclear whether support is simply disabled or not present on the silicon. Intel went to great lengths to prevent people from enabling the AVX-512 units on 12th-gen Core CPUs, so it’s possible the company removed them from Raptor Lake designs entirely.

According to SiSoftware, the Core i9-13900 will have 36 megabytes of L3 cache (20 percent more than the Core i9-12900) and support up to DDR5-5600 memory, PCIe 5.0 and Thunderbolt 4. Performance cores now have two megabytes of L2 cache per core, and the 16 efficiency cores have 16 megabytes of shared L2 cache, nearly double that of its Alder Lake counterparts.

When it comes to testing, the aggregated results suggest Raptor Lake can deliver 33 to 50 percent higher performance on basic computational tasks over Alder Lake. In vectorized and SIMD tests, the 13th-generation portion was about five to eight percent faster. This was achieved with a technical example with performance cores at 3.7 GHz and efficiency cores at 2.76 GHz. Both clock numbers are quite low, and SiSoftware notes that Alder Lake’s overall performance comes in at just four to six percent.

But if these results pay off, Intel may have found a way to match AMD’s Zen 4 with Raptor Lake. The two architectures will likely pack a punch in real-world performance testing, but we’ll have to wait and see.
