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

wccftech.com:

The latest benchmarks of AMD's Ryzen 9 7945HX3D Laptop CPU have leaked out showcasing that the 3D V-Cache chip still retains some great multi-threaded performance.

The AMD Ryzen 9 7945HX3D will be the first CPU for laptops that comes integrated with the 3D V-Cache technology. The chip is releasing next week on the 22nd of August but benchmarks leaked within the Geekbench database give us a reference point of what to expect from the chip besides the gaming performance. But before that, let's quickly recap the specifications.

AMD Ryzen 9 7945HX3D CPU Specifications

The AMD Ryzen 9 7945HX3D CPU comes with a 16-core and 32-thread configuration which is implemented in a dual CCD layout. Each CCD itself carries 32 MB of L3 cache for a total pool of 64 MB but one of these CCDs comes with a 3D V-cache stack of 64.0 MB which increases the total pool to 128 MB. The CPU features a base clock speed of 2.3 GHz which is 200 MHz lower than the Ryzen 9 7945HX but the boost frequency remains the same at 5.4 GHz.

Considering the minute difference in the way voltages and power are handled for the 3D V-Cache chip, a slight reduction in clock speeds was expected. Other specifications include a 55W+ TDP as this chip is ultimately an HX design and some form of tuning such as PBO and CO will be available for consumers to play around with. The standard HX chip features a TDP of 55-75W+.

AMD Ryzen 9 7945HX3D CPU Performance

The performance of the CPU was tested on the ASUS ROG Strix G733PYV (ROG STRIX SCAR 17 X3D) laptop which is the only officially announced product to feature the 3D V-Cache CPU.  In Geekbench 6, the chip scores 2783 points in single-core and 16,080 points in multi-core tests which is a tad bit slower than the standard 7945HX chip
