AMD Ryzen 9 5950X vs Intel Core i9-11900K vs Intel Core i7-11700K
AMD Ryzen 9 5950X
► remove from comparison
The AMD Ryzen 9 5950X is a high-end 16-core, hyperthreaded (SMT) Vermeer Series desktop processor. With 32 threads, the new flagship offers as many threads as the AMD Ryzen 9 3950X. Introduced on October 8, 2020, the Ryzen 9 5950X is the fastest 16-core processor and is specified at 105 watts TDP.
The Ryzen 9 5950X runs at 3.4 GHz to 4.9 GHz (single core). Wen all 16 cores are loaded, up to 4.5 GHz are still possible.
The internal structure of the processor has not changed fundamentally at first glance. The CCX structure has changed a bit compared to Zen 2, because now a CCX consists of up to 8 CPU cores. So each individual core can access the complete L3 cache (32 MByte). Furthermore the CCX modules are connected to each other via the same I/O die, which we already know from Zen2. According to AMD, the Infinity fabric should now reach clock rates of up to 2 Ghz, which in turn allows a RAM clock of 4,000 MHz without performance loss.
Performance
The average 5950X in our database matches the Core i9-12900K, the Core i9-12900HX and also the Ryzen Threadripper 2970WX in multi-thread performance, making this Ryzen a great processor for pretty much any task imaginable as of mid 2022.
Power consumption
This Ryzen 9 series chip has a default TDP (also known as the long-term power limit) of 105 W. It will, however, happily consume much more than that as long as the cooling solution is able to handle the heat - even before one starts considering the possibility of overclocking the thing.
The Ryzen 9 5950X is built with TSMC's 7 nm process for average, as of mid 2023, energy efficiency.
Intel Core i9-11900K
► remove from comparison
The Intel Core i9-11900K is a high-end desktop CPU based on the Rocket Lake architecture. The CPU offers 8 cores and 16 threads clocked at 3.5 - 5.3 GHz (Turbo Boost 3.0 / TVB). With Turbo Boost 2.0, 5.1 GHz can be reached with a single thread. Using all cores, the CPU can clock up to 4.8 GHz. Adaptive Boost enables even higher multi-core frequencies (5.1 GHz all core Turbo) but uses a lot more power.
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) and offers 32 EUs. In the 11900K, the GPU is clocked from 350 - 1300 MHz.
Performance
The average 11900K in our database is in the same league as the Ryzen 7 5800X3D, as far as multi-thread benchmark scores are concerned. Which is an impressive result, as of mid 2022, and good enough for any task imaginable including content creation and professional gaming.
Power consumption
This Core i9 has a 125 W TDP, also known as the long-term power limit. Intel lets PC manufacturers reduce that value somewhat if required, 95 W being the lower limit, which would result in lower clock speeds and lower performance. The reality is, an 11900K can be much more power hungry than either of the two numbers imply simply because of its sheer might but also because it is manufactured on an old 14 nm Intel process that makes for lower-than-average, as of mid-2022, energy efficiency.
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.
