AMD Ryzen 9 7950X3D vs. Intel Core i9-13900K – Performance test of the fastest processors. Who will win the clash of giants?

From the moment the AM5 platform was introduced, we knew that in addition to the standard AMD Ryzen 7000 processors, the manufacturer also plans models with 3D V-Cache memory. The technology demonstration of the AMD Ryzen 7 5800X3D turned out to be promising, and today the new 3D V-Cache modules, based on the Zen4 architecture, officially debuted. The hero of this review will be AMD Ryzen 9 7950X3D, the long-awaited top representative of the family, which throws the Intel Core i9-13900K gauntlet. Thanks to the AMD Ryzen 9 7950X, the Reds have already managed to claim the title of the most powerful desktop processor in professional applications, but there was a certain lack when we looked at the performance in some PC games. AMD Ryzen 9 7590X3D was created to finally defeat the competitor also in such scenarios …

Treatments AMD Ryzen 7000 Codenamed Raphael, the next step in Zen architecture development introduces the new AM5 (LGA1718) platform that supports DDR5 and PCI-Express 5.0. The cores are made in a 5 nm process (previously 7 nm), while the I/O containing the remaining elements uses 6 nm (previously 12 nm) lithography. Another fundamental change is the addition of an integrated Radeon graphics chip based on the RDNA 2 architecture, which its predecessors were completely denied except for the G / PRO series. However, the architecture of the processors themselves has not undergone significant changes – CCD modules with as many as eight cores are still used, and everything is connected by an internal Infinity Fabric bus. There are also separate clock ranges for RAM, IMC, and IF, but this time they are more separated. AMD reports an additional 30% increase in IPC over its predecessors due to a front-end rebuild, command queue expansion, L2 cache doubling, and improved FP32 operations, decoders, and AVX-512 instructions. Higher clock speeds also contribute significantly to better performance, while in the case of the 7000X3D family, there is an additional set of 3D cache.

The AMD Ryzen 9 7950X3D is a slick 3D version of the AMD Ryzen 9 7950X that dominated software, but not necessarily gaming. The version with the extra L3 cache should change things…

In terms of rigorously constructed, tested AMD Ryzen 9 7950X3D It’s practically a twin of the AMD Ryzen 9 7590X, because it’s built on two full chip (CCD) chips. Each has 8 physical cores, and is also supported by Simultaneous Multi-Threading Technology (SMT), so the processor has 16 cores in total and supports 32 threads. The main difference is the increased cache size AMD Ryzen 9 7950X3D L3, which the hero of this review has 128 MB instead of 64 MB. L1 and L2 caches remain unchanged. Additional resources were placed on top of the primary L3 Cache and connected directly to a single CCD block, using joint TSVs (through Silicon Vias) developed with TSMC engineers. Since the release of the AMD Ryen 7 5800X3D, the manufacturer has also developed a number of solutions built into the chipset drivers to optimize the use of the correct chip, so that a device with 3D V-Cache always gets priority. The greatest benefits should be expected in computer games, which are sensitive to the performance of the memory subsystem, which should allow the AMD Ryzen 9 7950X3D to compete with the Intel Core i9-13900K.

The base clock of the AMD Ryzen 9 7950X3D is set to 300MHz lower than the Ryzen 9 7950X, but the actual frequencies are what matter. In the case of a multi-core load, this difference actually persists, while the old 5700MHz is left in one core. Of course, to achieve the above hours, you must have a proper cooling system. This is a little easier than before, because the TDP factor is 120 instead of 170W, while the test piece ran cooler and ran at lower factory voltages than the Ryzen 9 7950X. Although rumors have circulated that Ryzen 7000X3D Allowing overclocking, there was obviously some misunderstanding. The multiplier is locked again, so overclocking was probably understood as PBO and EXPO. I personally test processors without electric mufflers, so I didn’t get anything above standard results. Also, the integrated graphics, PCI-E 5.0 controller and DDR5 memory have not changed. Officially, AMD guarantees 5200MHz in a single/dual 2x configuration, currently the unofficial limit is 6000-6200MHz.
