AMD Ryzen 9 5950X vs Intel Core i7-11700K vs Intel Core i5-11400T
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 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.
Intel Core i5-11400T
► remove from comparison
The Intel Core i5-11400T is a power-efficient six-core desktop processor based on the new Rocket Lake architecture, which was introduced in March 2021. The processor clocks with a base clock of only 1.3 GHz and reaches an all-core boost of 3.7 GHz under load. Intel also gives the Rocket Lake processors the Hyperthreading feature, which allows the i5-11400T to process up to 12 threads simultaneously. As known, the Intel Core i5-11400F is manufactured in the 14 nm process. Nevertheless, many changes have been made with the Rocket Lake architecture, which is also reflected in the performance compared to the Comet Lake.
Performance
Compared to the Intel Core i5-10400T, the Core i5-11400T offers a significantly better IPC. This can be seen clearly in the single-core benchmarks. The multi-core performance also benefits from the better IPC compared to Comet-Lake. A performance increase of up to 20 percent can be expected.
Graphics
The processors integrates a Intel UHD Graphics 730 iGPU that features 24 EUs clocked at 350 - 1200 MHz.
Power consumption
The TDP turns out relatively low with 35 watts. This is the PL1 value. For Turbo, the Intel Core i5-11400T offers a higher TDP of up to 84 watts with PL2. However, this may only be applied for a maximum of 28 seconds (dew).
