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.
The Intel Core i5-8350U is a power efficient quad-core SoC for notebooks and Ultrabooks based on the Kaby Lake Refresh generation and was announced in August 2017. Contrary to its direct predecessor the Core i5-7300U, which were still dual-cores, the i7-8350U is equipped with four cores but at a lower base frequency of 1.7 GHz. The Turbo Boost can go up to 3,6 GHz and therefore also offer good short term single core speeds. The GPU is now named Intel UHD Graphics 620 but otherwise identical to the Intel HD Graphics 620. The integrated memory controller supports DDR4-2400 / LPDDR3-2133 and dual channel memory.
Architecture
Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.
Performance
According to Intel, the new quad core models are up to 40% faster than their dual core predecessors. Due to the reduced TDP and the same 14nm+ process, the long term performance and throttling behaviour will be interesting and depending on the laptop design. Therefore, the older 35 Watt quad-core models should be faster in applications that demand longer CPU loads.
Contrary to Skylake, Kaby lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors announced in January should also support HDCP 2.2.
Power Consumption
The chip is manufactured in an improved 14nm process with FinFET transistors (14nm+), the same as the 7th Gen Kaby Lake processors. Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. Depending on the usage scenario, the TDP can vary between 7.5 (cTDP Down) and 25 Watts.
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.
