AMD Ryzen 7 3800XT vs Intel Processor N97 vs AMD Ryzen 9 3900

AMD Ryzen 7 3800XT

The AMD Ryzen 7 3800XT is a fast desktop processor with 8 cores (octa core) based on the Zen 2 architecture. At launch it is the fastest 8-core-CPU of the Matisse series. The 3800XT clocks from 3.9 GHz (base) up to 4.7 GHz (Turbo). All eight cores can reach up to 4.2 GHz.

Performance

The average 3800XT in our database is in the same league as the Core i5-12500H, Core i5-13500H, Core i9-10910, Ryzen 7 5700G, Ryzen 7 7735HS, Ryzen 9 6900HS, Ryzen 9 6900HX, as far as multi-thread performance is concerned.

Power consumption

This Ryzen 7 series processor has a default TDP, also known as the long-term power limit, of 105 W. Needless to say, if one was to overclock it, the chip's power consumption would go up by a huge margin.

The R7 3800XT is built with TSMC's 7 nm process making for average, as of mid 2023, energy efficiency.

Intel Processor N97

The Intel Processor N97 is an entry-level mobile CPU for thin and light laptops from the Alder Lake-N series. It was announced in early 2023 and offers no performance cores and 4 of the 8 efficient cores (E-cores, Gracemont architecture). The chip does not support HyperThreading and clocks with up to 3.7 GHz. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 6 MB L3-cache. 

Performance

The performance should be between the Intel Processor N100 and Intel Processor N200 and clearly below the Core i3-N300 and N305 due to the reduced core count. 

Features

The Alder Lake-N chips only support single channel memory with up to DDR5-4800, DDR4-3200 or LPDDR5-4800. The chip also supports Quick Sync and AV1 decoding (most likely same engine as in Alder Lake). Furthermore, Wi-Fi 6E and Bluetooth 5.2 are partly integrated (but no Thunderbolt). External chips can be connected via PCIe Gen3 x9 (via the PCH).

The integrated graphics adapter is based on the Xe-architecture and offers only 24 of the 32 EUs (Execution Units) operating at 1200 MHz. Due to the single channel memory, low clock speeds, and low shader count, the gaming performance of the iGPU is very limited.

Power consumption

The N97 has a base power consumption of 12 W and therefore double the amount of the N100. The CPU is built with a further improved 10nm SuperFin process at Intel (called Intel 7).

AMD Ryzen 9 3900

The Ryzen 9 3900 is a fast desktop CPU with 12 cores and 24 threads based on the Matisse series. It is the fastest 65 Watt CPU at launch in late 2019 and clocks the cores between 3.1 (base) to 4.3 (boost) clock (including Precision Boost). It uses 4 CCX-clusters where 3 of the 4 cores are activated. The CPU is manufactured in the modern 7nm process at TSMC. The I/O die on the package is separate and manufactured in 12 nm at Globalfoundries.

Due to the reduced Turbo speed, the Ryzen 9 3900 is aimed at content creators and other professionals that can make use of the 12 cores. For games, a fast 8-core CPU with higher boost clocks is the better choice.
