AMD Unleashes The Ryzen 9 7945HX3D, First 3D V-Cache CPU For Laptops & Powers ASUS ROG SCAR 17 X3D

wccftech.com:

AMD has just announced the world's first 3D V-Cache CPU for laptops, the Ryzen 9 7945HX3D, which will offer up to 128 MB of cache.

The AMD Ryzen 9 7945HX3D isn't just a rumor anymore and has been officially announced by the red team as its first 3D V-Cache chip. The chip features the same core configuration as the Ryzen 7045 "Dragon Range" CPUs with the Zen 4 core architecture coming in a chiplet package design & featuring a similar layout as the desktop-grade chips. This time, AMD has brought the stacked 3D cache treatment over to its laptop CPUs which will make for an impressive flagship offering.

So starting straight with the specifications, the AMD Ryzen 9 7945HX3D 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 that 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+.

You will also get the same AMD Radeon 610M GPU powered by the RDNA 2 graphics architecture. This small 2 Compute Unit chip is ample for lightweight workloads that don't require the dGPU & can help save some crucial battery time. Of course, for gaming, you will have to use the dGPU since the
