AMD Ryzen 9 7900 vs Intel Core i7-11700K vs AMD Ryzen 9 7900X
AMD Ryzen 9 7900
► remove from comparison
The AMD Ryzen 9 79 00 is a high-end desktop processorfrom the Raphael series with 12 cores and hyperthreading (SMT), which means it can process up to 24 threads simultaneously. Launched in early 2023, the Ryzen 9 7900 is the fastest 12-core processor with 65 watts TDP.
The Ryzen 9 7900 clocks at 3.7 GHz base clock and reaches up to 5.4 GHz on one core in Turbo mode. This is also the difference to the higher clocked Ryzen 9 7900X.
At first glance, the internal structure of the processor has not changed fundamentally. The AMD Ryzen 9 7900 is still based on the chiplet design consisting of two CCD clusters, each containing a CCX with 8 cores. However, the manufacturing process has been scaled down to 5 nm, which ensures higher clock rates. There is also the IO die, which contains the memory controller and the iGPU, among other things. This is now manufactured in a 6 nm structure width.
The AMD Ryzen 9 7900 can impress in games thanks to the significantly improved IPC.
Intel Core i7-11700K
► remove from comparison
The Intel Core i7-11700K is a high-end desktop CPU based on the Rocket Lake architecture. The CPU offers 8 cores and 16 threads clocked at 3.6 - 4.9 GHz. The TDP is rated at 125 Watt (PL1, power limit sustained load) but the PL2 is set to around 250 Watt for short term boosts (up to 56 seconds).
The Sunny Cove processor cores (known from the Ice Lake mobile CPUs) offer larger caches and an improved IPC (up to 19%). Furthermore, the chip also includes (partly) integrated WiFi 6E and Thunderbolt 4. The platform supports PCIe 4.0 and Intel DL Boost for AI acceleration.
The faster Rocket Lake-S CPUs also integrate a new Intel UHD Graphics 750 that is based on the current Intel Xe architecture (e.g. mobile Tiger Lake).
The CPU is manufactured on an old 14 nm process like the Comet Lake predecessors.
AMD Ryzen 9 7900X
► remove from comparison
The AMD Ryzen 9 7900X is a fast high-end desktop processor of the Raphael series. It offers 12 cores based on the Zen 4 architecture that supports hyperthreading (24 threads). The cores clock from 4.7 (base) up to 5.7 GHz (single core boost). When all 12 cores are fully loaded, 5.1 GHz is the max. clock speed. The 7900X is the second fastest Ryzen at launch, only bested by the Ryzen 9 7950X with 4 more cores.
The performance of the R9 7900X is clearly better than the old Ryzen 9 5900X thanks to the improved architecture and modern 5nm process. Compared to Intels Raptor Lake Core i9-13700K the single-core performance is slightly lower and the multi-core performance slightly faster. The gaming performance is a bit lower, and is on average only on par with the Core i5-13600K and also lower than the old Ryzen 7 5800X3D.
The Raphael series still uses a chiplet design with two CCD-clusters (each with 8 possible cores) in 5nm and an IO-die (including the memory controller and the Radeon Graphics iGPU) in 6nm.
