SiSoftware has recently published a preview of Intel’s upcoming 13th generation core CPU – the Core i9 13900. This review isn’t like all other typical reviews as the testing wasn’t based on any hardware. Instead, the testing was an accumulation of results which existed in the SiSoftware Sandra database. It won’t be wrong to call this merely an overview of the new architecture with a slight focus on the elements of actual performance testing.
Let’s take a little recap on the specs side of things. The Intel Core i9-13900 is a 24-core processor featuring 8 Performance Cores and 16 Efficient Cores. SiSoftware claims that the processor is based on an updated Intel 7+ process technology and has a 20 percent larger L3 cache. It comes with a DDR5 memory with fast speeds reaching up to 5600 MT/s. This is quite an improved number as compared to the speed of 4800 MT/s on Alder Lake.
Raptor Lake’s L2 cache has also improved and is now twice as big when it comes to its Performance and Efficient cores. It has improved by 2 MB per core (big) and 4 MB per cluster of cores (4 small cores). With massive improvement in terms of performance, the Raptor Lake is only missing the AVX-512 support.
This preview by SiSoftware also shows the ALU/FPU test results which show 33 to 50 percent improvement over the Alder Lake. What shouldn’t be missed is that these results were generated with lower clock speeds. Raptor Lake stands at 3.7 GHz performance core and 2.76 GHz efficient core as opposed to Alder Lake’s 5 GHz performance core and 3.8 efficient core. We also have the SIMD test results which show an increase in performance by 5 to 8 percent over Alder Lake.
We are only a few months away from the official launch of Intel’s 13th Generation Core desktop processor. Some sources are claiming the launch month to be a month before the launch of NVIDIA’s GeForce RTX 40 series which makes August or October likely candidates.
