AMD Ryzen 7 9700X vs AMD Ryzen 7 7800X3D vs AMD Ryzen 9 7900
AMD Ryzen 7 9700X
► remove from comparison
The AMD Ryzen 7 9700X is an upper mid-range desktop CPU of the Granite Ridge product family that sports 8 Zen 5 cores (16 threads) running at 3.8 GHz to 5.5 GHz, along with PCIe 5 support and a basic RDNA 2 architecture iGPU. The Ryzen was launched in June 2024, with sales slated to start some time in August.
Architecture and Features
Like Strix Point APUs, Granite Ridge processors make use of the new Zen 5 microarchitecture. However, there are no efficient cores here; all of 9700X's cores are full Zen 5 cores with a "proper" Zen 5 implementation, not the simplified mobile version that has a lower AVX-512 performance. 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, desktop Zen 5 delivers a 16% IPC uplift over Zen 4 thanks to branch prediction improvements and other refinements.
Elsewhere, the 9700X has 32 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 9700X is unlocked for overclocking. Naturally, the AM5 socket CPU fully supports Windows 11, 64-bit Windows 10 as well as many Linux distros.
Performance
In our review, the Ryzen 7 delivered multi-thread benchmark scores very close to those of the Ryzen AI 9 HX 370 and 375, as well as the Core i7-12700 and i7-12700K.
Graphics
The Radeon 610M comes equipped with just 128 unified shaders running at up to 2,200 MHz. While this certainly isn't a gaming GPU, it's fast enough to run some competitive titles such as Counter-Strike 2 (~50 fps at 1080p / Low) as well as older (pre-2019) titles.
It can HW-decode many popular video codecs including first and foremost AVC, HEVC, VP9, AV1.
Power consumption
The CPU cores are built with TSMC's N4P process for a good, as of mid 2024, power efficiency. (Apple is the leader in this regard with the second-generation 3 nm process.)
The Ryzen 7's long-term TDP is either 65 W or 105 W, with each user free to make their own choice. If overclocked, its power consumption figures will increase significantly.
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).
AMD Ryzen 9 7900
► remove from comparison
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.
