AMD Ryzen 7 7800X3D vs Intel Core i7-9700K vs AMD Ryzen 9 7950X3D
AMD Ryzen 7 7800X3D
► remove from comparison
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).
Intel Core i7-9700K
► remove from comparison
The Intel Core i7-9700K is a high end desktop processor based on the Coffee Lake architecture. It offers an open multiplicator for easy overclocking and integrates 8 cores (no Hyperthreading therefore also 8 threads) clocked at 3.6 - 4.9 GHz and it needs a new Z390 based mainboard.
Thanks to the two additional cores, the performance in multi-threaded applications is even better than the old Core i8-8700K with 6 cores and Hyperthreading. As a high end desktop CPU, the i9-9700K is suited even for very demanding applications and perfect for 3D gaming.
The integrated Intel UHD Graphics 630 graphics card is clocked at up to 1.2 GHz and offers no advantage compared to previous generations. As it is a very low end GPU, only some low demanding games like Hearthstone can be played with it (see GPU page for benchmarks).
Intel specifies the TDP at 95 Watt, so if the CPU is used in laptops a big and chunky cooling system is needed to avoid throttling and lower clock speeds under sustained loads. When overclocking the CPU, the power consumption can easily rise up to 200 Watt and higher.
AMD Ryzen 9 7950X3D
► remove from comparison
The AMD Ryzen 9 7950X3D is a high-end desktop processor of the Raphael series with 16 cores and SMT (Simultaneous Multithreading), which means it can process up to 32 threads simultaneously. With the release in February 2023, the Ryzen 9 7950X3D is AMD's fastest consumer processor and the new top model of the 7000 series. The CPU cores clock from 4.2 GHz (base clock) up to 5.7 GHz (single core Turbo). In addition, the AMD Ryzen 9 7950X3D has a CCD with 8 cores that can access the fast 3D V-cache, which offers considerably more gaming performance.
The performance of the AMD Ryzen 9 7950X3D is consistently excellent in all applications tested. In addition, AMD was again able to increase the single-thread performance compared to the non-X3D models. Nevertheless, the lower base clock compared to the AMD Ryzen 9 7950X means that a small drop in multi-thread performance has to be accepted.
The internal structure of the processor is comparable to the previous AMD Ryzen 9 7950X. The AMD Ryzen 9 7950X3D is also still based on the chiplet design consisting of two CCD clusters with 8 cores each. However, the two CCDs differ significantly from each other because one offers the fast 3D V-Cache, which primarily improves gaming performance. In testing, the AMD Ryzen 9 7950X3D was able to put the Intel Core i9-13900K in second place and is the fastest gaming CPU on the market at the time of testing.
The AMD Ryzen 9 7950X3D is an extremely energy-efficient CPU with up to 162 watts (PPT) and is significantly more frugal under load than an AMD Ryzen 9 7950X (max. 230 watts).
