Though the Core i9-13900K from Intel received’t be out there till subsequent month, Fanatic Citizen has managed to supply a complete evaluation of the highest Raptor Lake CPU. OneRaichu, one of the vital well-known leakers on Twitter who has a status for being extraordinarily correct, labored with ESCM on the analysis. Fanatic Citizen has constantly supplied correct info on quite a lot of future CPUs. So let’s begin with the necessities.
The Intel Core i9-13900K, which has 24 cores and 32 threads in an 8 P-Core (Raptor Cove) and 16 E-Core (Gracemont V2) configuration, is the top-tier Raptor Lake processor.
The CPU is about as much as run at 3.0 GHz base pace, 5.8 GHz single-core enhance (1-2 cores), and 5.5 GHz all-core enhance (all 8 P-Cores). The CPU has a 125W PL1 ranking that goes as much as 250W and 68 MB of shared cache.
Each DDR5 and DDR4 platforms had been used to check the Intel Core i9-13900K. The Z690 Taichi Razer Version and an unnamed Z790 motherboard had been used, however the precise product identify can’t be revealed because of NDA.
The motherboards had been put by their paces with DDR5-6000 CL30 and DDR4-3600 CL17 reminiscence kits, in addition to a Radeon RX 6900 XTXH graphics card. The CPU was cooled by a NZXT Kraken X73 AIO. The CPU can assist native reminiscence speeds of as much as DDR5-5600, whereas Alder Lake can solely assist DDR5-4800 native JEDEC speeds.
Fanatic Citizen did the standard single-core, multi-core, and gaming utility exams whereas OneRaichu evaluated the reminiscence, bandwidth, and cache efficiency of the Raptor Lake Core i9-13900K and the Alder Lake Core i9-12900K.
OneRaichu demonstrates how the brand new ring bus design, which has a boosted frequency, permits all P-Cores and E-Cores to realize a constant latency and never dip to a decrease frequency leading to bigger latencies as we noticed with the Alder Lake CPUs. Subsequent, we’ve got the efficiency benchmarks.
The full frequency & cache uplift permits for improved total single-threaded efficiency, regardless that the IPC of the P-Core doesn’t expertise a big bump as detailed above. The Raptor Lake Core i9-13900K gives a 12.5% enchancment in single-threaded efficiency over Alder Lake. The Gracemont E-cores do expertise a modest 6% rise in IPC efficiency, whereas the 13900K’s further E-cores enable for vital multi-threaded efficiency beneficial properties. The flagship of the thirteenth era performs 42% higher on common than the earlier era, which is a big enchancment.
The outlet additionally examined quite a lot of video games, and it seems that those who rely on CPU pace would expertise a large bump, averaging roughly 10%. Whereas the FPS does go up, the thirteenth Gen Raptor Lake CPUs’ bigger L2 and L3 cache capacities are what actually make a distinction within the 0.1% lows.
Whereas the Intel Core i9-13900K consumes 253W at load in AIDA64’s FPU check, enabling “Limitless Energy Mode” will increase Raptor Lake’s energy consumption to 343W.
As a result of it is a stress check, real-world energy utilization in video games and functions will differ, however Fanatic Citizen will share these numbers later. The total evaluate could be discovered right here. It stays to be seen whether or not this vital efficiency enhance might be enough for Intel to compete with AMD’s Ryzen 7000 CPUs, which have additionally considerably elevated single and multi-threaded efficiency.
