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).
The Ryzen 9 9950X is a very, very powerful desktop CPU of the Granite Ridge product family that features 16 Zen 5 cores (32 threads), PCIe 5 support and a basic iGPU. The Ryzen was launched in June 2024, with sales slated to start in August.
The 9950X shares some of the specifications with the mighty Zen 4-powered Ryzen 9 7950X, including (but not limited to) the 16 MB L2 cache, the 64 MB L3 cache, the 5.7 GHz top clock speed and the 170 W long-term TDP.
Architecture and Features
Just like Strix Point APUs, Granite Ridge processors make use of the new Zen 5 microarchitecture. However, there are no efficient cores here; all of 9950X's cores are full Zen 5 cores. Furthermore, Granite Ridge is a multi-die design with only the CPU cores produced using a fairly modern 4 nm TSMC process. Strix Point processors are a single-die design, from what we know.
According to AMD, Zen 5 delivers a 16% IPC improvement over Zen 4 thanks to branch prediction improvements and other refinements.
Elsewhere, the 9950X has an impressive 64 MB of L3 cache and 24 direct PCIe 5 lanes (3.93 GB/s throughput per lane) with up to 12 additional PCIe 4 lanes available depending on the motherboard. It supports DDR5 RAM as fast as 5,600 MT/s (up to 8,000 MT/s if overclocked).
The 9950X is unlocked for overclocking. Naturally, the AM5 socket CPU supports Windows 11, 64-bit Windows 10 as well as many Linux distros.
Performance
According to early July leaks, its multi-thread performance is about as good as that of the 24-core Core i9-14900K Intel CPU. We'll definitely update this section once we get our hands on a system powered by the 9950X.
Graphics
The Radeon 610M comes equipped with just 128 unified shaders running at up to 2,200 MHz. Its gaming performance is slated to be extremely low and only just sufficient for pre-2020 games in resolutions such as 1024x768.
Power consumption
The CPU cores are built with TSMC's N4P process for good, as of mid 2024, power efficiency. (Apple is the leader in this regard with the second-generation 3 nm process.)
The Ryzen 9's long-term TDP is 170 W. It'll probably consume up to 250 W when under heavy short-term loads. If overclocked, the power consumption figures will increase significantly.
