AMD has introduced the brand new Ryzen 9 7945HX3D, the world’s first notebook CPU with the corporate’s 3D V-Cache technology.
The 7945HX3D is basically the 7945HX however with double the L3 cache. While the L1 and L2 cache stay at 1MB and 16MB, respectively, the L3 cache goes from the 7945HX’s sizable 64MB to a powerful 128MB for a complete of 145MB cache.
Introduced first on the Ryzen 7 5800X3D desktop processor final 12 months, the AMD 3D V-Cache technology primarily stacks an additional layer of reminiscence on the CPU die. While most apps present no enchancment from the added cache, video games have a tendency to learn tremendously from it. The additional reminiscence on die means video games do not must entry the slower and bodily distant system reminiscence as typically, leading to quicker processing of every body and better body charges general.
The 7945HX3D is in any other case similar to the 7945HX. It has 16 Zen4 cores and 32-threads evenly cut up throughout two core complexes. Like the 7945HX, the cache can also be cut up throughout the 2 CCD however on the 7945HX3D one CCD will get a further 64MB of L3 cache, leading to 96MB on one CCD and 32MB on the opposite one. This additionally signifies that just one CCD with 8-cores is used for gaming, with the opposite CCD being parked except expressly requested by this system. This conduct is just like the desktop 7950X3D and 7900X3D elements.
The 7945HX3D can enhance as much as 5.4GHz and might be overclocked manually or robotically utilizing AMD Precision Boost Overdrive. Default TDP is 55W and might be configurable between 55W and 75W by the notebook producer. Max working temperature has been lowered to 89°C just like different 3D V-Cache fashions as the additional reminiscence layer prevents efficient warmth dissipation and requires the chip to run cooler.
The 7945HX3D will first seem on the ASUS ROG Scar 17 beginning August 22 and ultimately on different fashions worldwide.
