AMD Ryzen 3 3300X vs AMD Ryzen 7 7800X3D vs AMD Ryzen 7 7700

AMD Ryzen 3 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.

AMD Ryzen 7 7800X3D

The AMD Ryzen 7 7800X3D is a high-end desktop processor from the Raphael series with 8 Zen 4 cores and SMT (Simultaneous Multithreading), allowing it to handle up to 16 threads simultaneously. After its announcement in January 2023 at CES in Las Vegas, it was launched in April 2023. Following the launch of the two top models, the AMD Ryzen 9 7900X3D and the AMD Ryzen 9 7950X3D, the third model was introduced, which offers significantly more gaming performance with the 3D V-Cache.

The CPU cores have a base clock of 4.2 GHz and can be boosted up to 5 GHz (single-core turbo). The AMD Ryzen 7 7800X3D features a CCD with 8 cores, which includes the fast 3D V-Cache. This differs significantly from the two Ryzen 9 models, as they have two CCDs, but only one of them can utilize the 3D V-Cache.

The performance of the AMD Ryzen 7 7800X3D is consistently good, although its multi-threaded performance suffers a bit due to the eight native compute cores. However, the real strength of the AMD Ryzen 7 7800X3D lies in gaming performance, where it excels. In tests, we see consistently high gaming performance, even surpassing that of an Intel Core i9-13900K.

In terms of power consumption, the AMD Ryzen 7 7800X3D aligns with the other two models featuring 3D V-Cache, making the 8-core processor extremely power-efficient. In numbers, this means that the AMD Ryzen 7 7800X3D is specified with a TDP of up to 120 watts. The PPT (Package Power Tracking) is also rated up to 162 watts. For comparison, an AMD Ryzen 9 7950X is specified with 170 watts (TDP) or 230 watts (PPT).

AMD Ryzen 7 7700

The AMD Ryzen 7 7700 is a fast high-end desktop processor of the Raphael series. It offers 8 cores based on the Zen 4 architecture that supports hyperthreading (16 threads). The cores clock from 3.8 (base) up to 5.3 GHz (single core boost). Compared to the faster Ryzen 9 CPUs (like the 7900X), the R7 offers less cores and slightly lower clock speeds.

The performance of the R7 7700 is slightly below the higher clocked AMD R7 7700X (that also features a higher TDP).

The Raphael series still uses a chiplet design with two CCD-clusters (each with 8 possible cores, so only one used for the 7700X) in 5nm and an IO-die (including the memory controller and the Radeon Graphics iGPU) in 6nm.

The Ryzen 7 7700 is rated at a TDP of only 65 Watt and therefore suited for smaller desktops (and cooling solutions).
