AMD Radeon RX 7900M “RDNA 3” Beats The NVIDIA RTX 4090 Laptop GPU In Vulkan Benchmark
AMD's flagship Radeon RX 7900M "RDNA 3" laptop GPU has been benchmarked and it is faster than NVIDIA's RTX 4090 Laptop chip in Vulkan tests.
The AMD Radeon RX 7900M is the flagship gaming GPU for laptops from the Red team and it is also the first laptop GPU ever to make use of a chiplet design. The chip was exclusively announced for the Alienware m18 laptop last month but despite being available since last month, there have been little to no reviews of the new Radeon GPU. We did get a teaser from a YouTuber, GizmoSlipTech, but besides that, there hasn't been much. But now, we have the latest benchmarks leaked out in Geekbench's OpenCL and Vulkan tests which should have surprising results.
AMD Radeon RX 7900M "Navi 31" GPU Specifications
The AMD Radeon RX 7900M GPU is based on the RDNA 3 graphics architecture and features a total of 36 WGPs or 72 Compute Units which make up a total of 4608 cores. That's 20% more cores than the 7800 XT & 10% lower cores than the 7900 GRE. Clock speeds for the GPU peak out at 2090 MHz.
In terms of memory, the GPU is equipped with a total of four MCDs which will enable a 256-bit wide bus interface & 16 GB memory capacities. That will get AMD on par with NVIDIA's top RTX 40 offerings such as the RTX 4090 which max out at 16 GB memory too. As for the power numbers, the AMD Radeon RX 7900M will be configured at a TGP of 160W & can be pushed up to 200W with SmartShift technologies.
AMD Radeon RX 7900M "Navi 31" GPU Performance
Starting with the numbers, we first want to outline the configuration. The Alienware m18 laptop is configured with the Ryzen 9 7945HX CPU which is the highest you can get and its a really missed opportunity to not include the Ryzen 9 7945HX3D model since this high-end gaming
