Ryzen 7 7800X3D’s gaming performance will not differ much from Ryzen 9 7950X3D
Recently, AMD’s Ryzen 9 7950X3D and Ryzen 9 7900X3D went on sale, but both products are priced very high. AMD is also preparing an 8-core Ryzen 7 7800X3D, which is priced $150 lower than the Ryzen 9 7900X3D, with a suggested retail price of $449, the same as the Ryzen 7 5800X3D. It is also designed with a single CCD, so it does not have the issue of communication between two CCDs, which is actually more attractive to gamers. However, AMD will not release the Ryzen 7 7800X3D until April 6th.
If the CCD without 3D V-Cache is turned off, the Ryzen 9 7950X3D is similar to the Ryzen 7 7800X3D. TechPowerUp conducted a test that compared the gaming performance of Ryzen 9 7950X3D when turning off these two CCDs. It should be noted that the maximum boost clock of Ryzen 7 7800X3D is only 5.0GHz, while the CCD with 3D V-Cache of Ryzen 9 7950X3D can reach up to 5.25GHz, so the simulated results are better than Ryzen 7 7800X3D.
The test showed that if the Ryzen 9 7950X3D only opens the CCD with 3D V-Cache, the gaming performance is similar to that of setting the scheduler to prioritize cache, slightly better than the default setting. If the CCD without 3D V-Cache is turned off, the gaming performance will drop by 13.5% compared to the default. Due to the clock difference, the gaming performance of the Ryzen 7 7800X3D will be slightly lower than that of the Ryzen 9 7950X3D when only the CCD with 3D V-Cache is turned on, but the difference should not be significant.
In terms of power consumption during gaming, when only the CCD with 3D V-Cache is turned on, the power consumption of Ryzen 9 7950X3D is significantly lower than the default, although the performance will vary with different games. On average, the power consumption of Ryzen 9 7950X3D during gaming under default settings is 56W, and it drops to 44W when only the 3D V-Cache CCD is turned on, which is similar to the gaming power consumption of Ryzen 7 7800X3D.
If the CCD without 3D V-Cache is turned off, the average gaming power consumption will increase to 67W, and the game frame rate will also decrease significantly. From this test, it is clear why AMD did not release Ryzen 7 7800X3D at the same time, as its gaming performance is not significantly different from that of Ryzen 9 7950X3D, and releasing both products simultaneously would affect the sales of the two Ryzen 9 7000X3D processors.
