AMD Ryzen 9 7945HX3D Laptop CPU Benchmarks Leak: Same Performance As 7945HX With 3D V-Cache Goodness

The technological landscape of laptop CPUs is witnessing another significant leap as AMD prepares to unveil its Ryzen 9 7945HX3D, a processor that integrates the revolutionary 3D V-Cache technology. Leaked benchmarks provide a glimpse into the performance prowess of this upcoming chip, revealing its remarkable multi-threaded capabilities and the gaming advantages brought forth by the 3D V-Cache. In this article, we delve into the details of the AMD Ryzen 9 7945HX3D’s specifications, performance, and the implications it holds for the laptop computing landscape.

Unveiling the AMD Ryzen 9 7945HX3D CPU Specifications

The AMD Ryzen 9 7945HX3D CPU showcases an impressive 16-core and 32-thread configuration, an arrangement implemented through a dual CCD layout. Each CCD boasts 32 MB of L3 cache, effectively creating a pool of 64 MB. However, what sets this processor apart is one of these CCDs featuring a 3D V-cache stack of 64.0 MB, effectively elevating the total cache pool to an astonishing 128 MB. While the base clock speed of 2.3 GHz is 200 MHz lower than its predecessor, the Ryzen 9 7945HX, the boost frequency remains unaltered at 5.4 GHz.

The slight reduction in clock speeds can be attributed to the intricate way voltages and power are managed within the 3D V-Cache architecture. Furthermore, the processor carries a TDP of 55W+ due to its HX designation, with customizable tuning options like PBO and CO enabling users to fine-tune the chip’s performance. It’s worth noting that the standard HX chip exhibits a TDP range of 55-75W+.

Performance Insights: AMD Ryzen 9 7945HX3D CPU

The ASUS ROG Strix G733PYV, specifically the ROG STRIX SCAR 17 X3D laptop, served as the testbed for evaluating the performance of the AMD Ryzen 9 7945HX3D CPU. The initial benchmarking utilized Geekbench 6, yielding a single-core score of 2783 points and a multi-core score of 16,080 points. Comparatively, these numbers are slightly below those of the standard 7945HX chip. However, when the test shifted to Geekbench 5, the Ryzen 9 7945HX3D exhibited impressive single-core and multi-core scores of 2146 points and 20,074 points, respectively, effectively placing it on par with its non-3D V-Cache sibling.

It’s important to acknowledge that the performance discrepancy in Geekbench 6 might be attributed to the usage of the “Performance” profile, whereas the other tests capitalized on the “Turbo” profile while executing the same benchmark. This discrepancy is highlighted by the core clock log file, indicating boosts of up to 5.3 GHz in Geekbench 6 and up to 5.4 GHz within the Geekbench 5 benchmark.

Paving the Way for Enhanced Gaming and Efficiency

The advent of high-end 3D V-Cache technology in the Ryzen 9 7945HX3D is poised to create ripples in the competitive landscape, with a potential impact on Intel’s Raptor Lake-HX and the forthcoming 14th-gen refresh processors. The added efficiency and gaming performance offered by these V-Cache boosted Dragon Range CPUs appear poised to challenge Intel’s power-hungry offerings, and the benchmarks certainly attest to AMD’s commitment to pushing the boundaries of laptop CPU performance.


In summary, the leaked benchmarks of the AMD Ryzen 9 7945HX3D Laptop CPU have shed light on its impressive multi-threaded performance and gaming capabilities, thanks to the integration of the innovative 3D V-Cache technology. With its 16-core, 32-thread configuration, substantial cache pool, and remarkable clock speeds, the Ryzen 9 7945HX3D is poised to redefine the laptop computing experience. As we eagerly await its official release on August 22nd, it’s clear that AMD is determined to maintain its stronghold in the competitive CPU market.
