AMD Radeon 660M Graphics

AMD Radeon 660M graphics is an integrated graphics card for Ryzen 5 6000 Series laptop/notebook CPUs launched on Jan 4th, 2022. It was codename as “Rembrandt“. It is a cut-down version of the Radeon 680M iGPU.

The GPU was later Refreshed as “Rembrandt+” and launched on Jan 3rd, 2024 for Ryzen 3 and 5 7000 series Laptop CPUs. All the Specs are similar, there is just a change in the naming scheme for the Ryzen 5 7000 series.

The only difference is in the Ryzen 3 7000 series Laptop CPUs which come with Radeon 660m 4 CUs and 1800 Mhz clock speed. A low-profile version for low-performing CPUs.

I have collected all the data from reputable sites like Techpowerup, Notebook-Check, etc. for the specs and performance of the Radeon 660M GPU.

Let’s dive into all the capabilities, specs, benchmarks, and gaming performance of the Radeon 660M graphics.

GPU Frequencies

In desktop/notebook GPUs, the graphics cards are tuned according to their manufacturers/Board partners, depending on which frequencies they want in their notebook/desktop GPUs.

If they want power efficiency, they want to tune the frequencies lower than normal, resulting in less power consumption and loss of performance.

If they want performance, they will either let the frequencies default or tune the frequencies a little higher for more performance. Hence, the GPU will consume more power.

The Higher the clock speed, the better the performance of the GPU.

Video Memory (VRAM) capacity and Type

It tells how much VRAM Radeon 660M GPU has, VRAM type, size, bus, and bandwidth. Since this is an i-GPU, it doesn’t have a dedicated VRAM and uses a part of the system RAM.

AMD Radeon 660M VRAM max memory allocation capacity is only 2GB but can be increased by increasing the RAM capacity.

Synthetic Benchmark Performance

These benchmarks are measured by GPU benchmarking software like 3DMark Time Spy graphics score, 3DMark Fire strike graphics, Passmark Performance Testsuite, and Geekbench 6.2.

What is the Passmark Performance Test suite?

The Passmark performance test suite is a 3D benchmark designed for video cards by using the DirectX feature.

It puts a load on the GPU for various DirectX versions like DX9, DX10, DX11, and DX12 provides separate benchmark results, and gives you the average G3D mark score.

What is the 3D Mark Time Spy benchmark?

It calculates both the CPU and GPU performance and gives you the system’s overall score. It also ranks your overall score on the internet and ranks your system accordingly.

What is the 3D Mark Fire Strike benchmark?

It is a standard to test your gaming PC graphics render capability in detail and complexity which is quite taxing to the gaming hardware. It uses DirectX 11 API and renders at 1080P resolution.

What is the Geekbench 6 GPU benchmark?

Geekbench 6 GPU benchmarks your graphics card computing power in gaming, image processing, video editing, photography, and machine learning. It tests your GPU Open CL, metal, and Vulkan score.
