AMD’s flagship Radeon RX 7900M “RDNA 3” laptop computer GPU has been benchmarked and it’s quicker than NVIDIA’s RTX 4090 Laptop computer chip in Vulkan assessments.
AMD Radeon RX 7900M “RDNA 3” Flagship Laptop computer GPU Benchmark Leak: Sooner Than 4090 Laptop computer In Vulkan, Slower Than 4080 Laptop computer In OpenCL
The AMD Radeon RX 7900M is the flagship gaming GPU for laptops from the Purple crew and it’s also the primary laptop computer GPU ever to utilize a chiplet design. The chip was solely introduced for the Alienware m18 laptop computer final month however regardless of being obtainable since final month, there have been little to no evaluations of the brand new Radeon GPU. We did get a teaser from a YouTuber, GizmoSlipTech, however in addition to that, there hasn’t been a lot. However now, we now have the most recent benchmarks leaked out in Geekbench’s OpenCL and Vulkan assessments which ought to have stunning outcomes.
AMD Radeon RX 7900M “Navi 31” GPU Specs
The AMD Radeon RX 7900M GPU is predicated on the RDNA 3 graphics structure and encompasses a complete of 36 WGPs or 72 Compute Items which make up a complete of 4608 cores. That is 20% extra cores than the 7800 XT & 10% decrease cores than the 7900 GRE. Clock speeds for the GPU peak out at 2090 MHz.
When it comes to reminiscence, the GPU is provided with a complete of 4 MCDs which is able to allow a 256-bit huge bus interface & 16 GB reminiscence capacities. That can get AMD on par with NVIDIA’s prime RTX 40 choices such because the RTX 4090 which max out at 16 GB reminiscence too. As for the facility numbers, the AMD Radeon RX 7900M might be configured at a TGP of 160W & could be pushed as much as 200W with SmartShift applied sciences.
AMD Radeon RX 7900M “Navi 31” GPU Efficiency
Beginning with the numbers, we first wish to define the configuration. The Alienware m18 laptop computer is configured with the Ryzen 9 7945HX CPU which is the very best you will get and its a extremely missed alternative to not embody the Ryzen 9 7945HX3D mannequin since this high-end gaming laptop computer might be good with the increase that comes from 3D V-Cache CPUs. The CPU nonetheless operates effectively over 5 GHz & there’s additionally 32 GB of DDR5-5200 reminiscence.
Efficiency-wise, the AMD Radeon RX 7900M Laptop computer GPU scored 171,430 factors which makes it quicker than each the NVIDIA GeForce RTX 4090 & RTX 4080 laptop computer GPUs and nearly on par with the RTX 4070 Ti Desktop graphics card. In order that’s primarily RTX 3090 Ti or RX 6950 XT efficiency in a laptop computer kind issue. The GPU is 9% quicker than the 4090 Laptop computer & 25% quicker than the 4080 Laptop computer GPUs.

We must always spotlight the Vulkan efficiency extra since that could be a extra common API utilized in video games than OpenCL. AMD having the lead there may be undoubtedly nice to see and extra according to what the corporate has formally revealed in its personal inside benchmarks. The AMD Radeon RX 7900M does characteristic a better goal TGP than the RTX 4080 however on the similar time, laptops that includes the GPU are going to price much less as detailed right here. Total, the Radeon RX 7900M is a robust RDNA 3 Laptop computer GPU however we might have liked to see it in additional laptop computer configurations and choices too.
