The Intel Core i7-10700K is a high-end desktop CPU based on the Comet Lake architecture. The CPU offers 8 cores and 16 threads clocked at 3.8 - 5.1 GHz. The TDP is rated at 125 Watt (PL1) but the PL2 is set to 229 Watt for short term boosts (up to 56 seconds).
The AMD Ryzen 7 5800X is an 8-core desktop processor with Simultaneous Multithreading (SMT), which allows it to process 16 threads simultaneously. With its launch on 08.10.2020, it is the fastest 8-core processor from AMD. The second fastest 8-core processor will be the AMD Ryzen 7 3800XT, followed by the more economical AMD Ryzen 7 3700X, also with 8 cores and 16 threads.
The Ryzen 7 5800X clocks with a base clock of 3.8 GHz and reaches up to 4.7 GHz on one core in turbo mode. When all 8 cores are utilized, the AMD Ryzen 7 5800X, like the AMD Ryzen 9 5900X, achieves up to 4.5 GHz.
At first glance, the internal structure of the processor has not changed fundamentally. The CCX structure has changed somewhat compared to Zen2, 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 2Ghz, which in turn allows a RAM clock of 4.000 MHz without performance loss.
Performance
The average 5800X in our database is in the same league as the Core i9-10900K and also the Core i7-12700F, as far as multi-thread benchmark scores are concerned.
In games, AMD's Ryzen 7 5800X can convince with its significantly improved IPC and even put Intel in its place. With the AMD Ryzen 7 5800X, gamers are well prepared for the future as simultaneous streaming is no problem with the new Ryzen 7 5800X. Semi-professional content creators, who need even more power, can choose a Ryzen 9 5900X or the Ryzen 9 5950X on the shelf.
Power consumption
The Ryzen 7 has a default TDP (also known as the long-term power limit) of 105 W. This applies as long as the CPU runs at stock clock speeds.
Ryzen 7 5800X is built with TSMC's 7 nm process; as rumors have it, the I/O die is manufactured separately on the 12 nm Global Foundries process.
The Intel Core i7-10700 is a high-end desktop CPU based on the Comet Lake architecture. The CPU offers 8 cores and 16 threads clocked at 2.9 - 4.8 GHz. All cores can run at up to 4.6 GHz.
Compared to the older Core i7-9700, the 10700 now enables HyperThreading and therefore in some applications a nice performance boost. The single core performance is quite similar.
The chip is manufactured on 14nm++ process at Intel. The TDP is rated at 65 Watt (PL1) but the PL2 is set to 224 Watt for short term boosts (up to 28 seconds).
