AMD Radeon RX 7600M XT vs AMD Radeon RX Vega 6 (Ryzen 4000/5000)

AMD Radeon RX 7600M XT

The AMD Radeon RX 7600M XT is a mobile upper mid-range graphics card based on the Navi 33 chip (RDNA 3 architecture) manufactured in 6nm. It features 2,048 cores (32 CUs - compute units) and 8 GB of fast GDDR6 graphics memory connected with a 128 Bit memory bus. The chip also includes 32 MB Infinity Cache. The clock speed of the cores will depend on the laptop according to AMD. The specified game clock speed is 2300 MHz (most likely at 120 W TGP). 

AMD compares the performance to the RTX 3060 desktop GPU and claims significantly faster frame rates in a couple of games (without Raytracing). Although the Raytracing performance did increase for RDNA 3, the GeForce GPUs are still faster in this regard.

The Navi 33 chip is manufactured at TSMC in the current 6nm process (versus 4nm of Nvidia RTX 4000 series). The power consumption (TGP) is specified at 75 to 120 Watt.

AMD Radeon RX Vega 6 (Ryzen 4000/5000)

The AMD Radeon RX Vega 6 is an integrated GPU for notebooks. It is used in certain Ryzen 5 APUs of the Renoir generation (Ryzen 4000 Mobile), which were launched in early 2020. The iGPU is based on the Vega architecture (5th generation GCN) and has 6 CUs (= 384 of the 512 shaders) clocked at up to 1,500 MHz. Compared to the similar Radeon RX Vega 6 in the Raven Ridge generation (Ryzen 2000 Mobile), the GPU is clocked significantly higher (1.500 versus 1.100 MHz Boost).

The performance depends on the configured TDP (12-54 W at launch), the clocks, the cooling, and the memory configuration). The GPU should benefit from fast dual-channel DDR4-3200 RAM (contrary to DDR4-2133 single-channel, which is also possible).

The Vega architecture offers some improvements over the Polaris generation and now supports DirectX 12 Feature Level 12_1. More information is available in our dedicated article about the Raven Ridge architecture.

The performance is clearly faster than the old RX Vega 6 thanks to the higher clock speed and faster main memory (if used). In first synthetic benchmarks, the Vega 6 was able to reach the performance of a dedicated GeForce MX150. In games it should be somewhere between a GeForce MX230 and MX150.

Thanks to the modern 7nm process and clever power-saving features, the power consumption is comparatively low (according to AMD), so the graphics adapter can also be used for slim and light notebooks.
