AMD Ryzen 9 7900 vs AMD Ryzen 7 3800XT vs AMD Ryzen 3 3300X

AMD Ryzen 9 7900

► remove from comparison AMD R9 7900

The AMD Ryzen 9 79 00 is a high-end desktop processorfrom the Raphael series with 12 cores and hyperthreading (SMT), which means it can process up to 24 threads simultaneously. Launched in early 2023, the Ryzen 9 7900 is the fastest 12-core processor with 65 watts TDP.

The Ryzen 9 7900 clocks at 3.7 GHz base clock and reaches up to 5.4 GHz on one core in Turbo mode. This is also the difference to the higher clocked Ryzen 9 7900X.

At first glance, the internal structure of the processor has not changed fundamentally. The AMD Ryzen 9 7900 is still based on the chiplet design consisting of two CCD clusters, each containing a CCX with 8 cores. However, the manufacturing process has been scaled down to 5 nm, which ensures higher clock rates. There is also the IO die, which contains the memory controller and the iGPU, among other things. This is now manufactured in a 6 nm structure width.

The AMD Ryzen 9 7900 can impress in games thanks to the significantly improved IPC.

AMD Ryzen 7 3800XT

► remove from comparison AMD R7 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.

AMD Ryzen 3 3300X

► remove from comparison AMD R3 3300X

The Ryzen 3 3300X is a mid-range desktop processor of the Matisse series with 4 cores and 8 threads. It clocks from 3.8 (base) - 4.3 GHz (boost) and uses the Zen 2 microarchitecture. It uses all four cores in a single CCX-cluster, unlike the slower Ryzen 3 3100 which uses two clusters. 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. The TDP is specified at 65 Watt and therefore the CPU wont need a big beefy cooler.

Thanks to the high clock rates, the Ryzen 3300X is performing similar than the old Core i7-7700K (a former high end CPU) and therefore a good pick for entry level gaming systems.
