AMD Ryzen 9 7945HX3D vs AMD Ryzen 7 7800X3D vs AMD Ryzen 7 7700

AMD Ryzen 9 7945HX3D

► remove from comparison AMD R9 7945HX3D

The AMD Ryzen 9 7945HX3D is a fast high-end laptop processor of the Dragon Range series. It offers 16 cores based on the Zen 4 architecture that supports hyperthreading (32 threads). The cores clock from 2.3 (base) up to 5.4 GHz (single core boost). Compared to the similar R9 7945HX, the 7945HX3D offers an additional 64 MB 3D V-Cache on one CCD-Cluster. This helps in some workloads that can use the additional fast cache (e.g. some games). The guaranteed base clock however was reduced from 2.5 to 2.3 GHz.

The performance of the R9 7945HX3D is similar to the R9 7945HX in workloads that wont make use of the bigger L3 cache. Most games however can use the additional memory. AMD e.g. was advertising the HX3D with 4% to 53% higher performance in 1080p high settings.

The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible cores) in 5nm and an IO-die (including the memory controller and the Radeon 610M iGPU) in 6nm. The chip integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB4), 28 PCIe 5.0 lanes (for GPU and SSDs) and a dual-channel DDR5-5200 memory controller.

The R9 7945HX3D is rated at a TDP of 55 Watt and can be configured up to 75 Watt (cTDP).

AMD Ryzen 7 7800X3D

► remove from comparison AMD R7 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

► remove from comparison AMD R7 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).
