Announcing the Ryzen 9 7950X3D, Ryzen 9 7900X3D and Ryzen 7 7800X3D CPUs with Zen 4 architecture last January, AMD continues to expand its 3D V-Cache product range. So much so that we told you that these solutions will come to mobile very soon. Today, AMD announced the Ryzen 9 7945HX3D, the first 3D V-Cache processor for laptops.Ryzen 9 7945HX3D introduced
According to AMD, the Ryzen 9 7945HX3D, which has 16 cores and 24 threads in a dual CCD arrangement, offers the same 5.4 GHz increased clock speed as the standard 7945HX and a 200 MHz lower base clock of 2.3 GHz. Each CCD of the CPU carries 32MB of L3 cache for a total pool of 64MB. However, one of these CCDs has 64.0 MB of 3D V-cache stack. Thus, the total amount of cache increases to 128 MB.
The Ryzen 9 7945HX3D will showcase a 55+ TDP compared to the base model (55-75W+). However, manufacturers will be able to make some adjustments to this value. The 7945HX is also powered by Radeon 610M which includes 2 Compute Units based on RDNA 2. But it is worth noting that this GPU will be responsible for light workloads. So for games, users will need external GPUs.When it comes to games, the AMD Ryzen 9 7945HX offers up to 53 percent performance gains over the base model, which is pretty impressive and represents a significant upgrade for mobile platforms. Here are the figures provided by AMD:
