Will we be playing God of War on Radeon 680M integrated graphics? We will check it with the help of AMD FSR 2.0 technology

We’ve known for a long time that the integrated AMD Radeon 680M chip is the fastest iGPU that’s appeared in laptops to date. In February we tested the full voltage variant of a gaming laptop, and we recently also published a test of the ASUS Zenbook S 13 OLED ultrabook with AMD Ryzen 7 6800U with a significantly lower power limit. You know how the iGPU is priced in the games we feature as part of the testing procedure. Now we will check how the Radeon 680M performs in the most demanding production.

AMD Rembrandt processors are in many ways more advanced pieces of silicon than they were with the Renoir or Cezanne APUs. Due to the expansion of integrated graphics chips, the area of ​​\u200b\u200bRembrandt chips has become slightly larger – 210 mm². By comparison, the Cezanne APU has an area of ​​180 square millimeters. The latest AMD processors consist of Zen 3+ cores with more than 50 minor or major modifications – their main goal was to increase power efficiency. Added to this are integrated graphics systems, based on the RDNA 2 architecture. Radeon 680M and Radeon 660M are the first iGPUs, and hardware acceleration accounts for Ray Tracing. Of course, performance itself is a completely different matter. The all-in-one TSMC 6 nm technological process is developed.

God of War is a very difficult production. We are checking whether it is possible to play on integrated Radeon 680M graphics with the help of AMD FidelityFX Super Resolution 2.0 technology.

The integrated RDNA 2 graphics chips are significantly modified from what we got with the Vega architecture. ia increase by 50% the number of computing blocks – from 8 CU in Vega to 12 CU in RDNA 2. There are also separate modules to support Ray Tracing, dual extended backend or dual L2 cache – from 1 MB (Vega) to 2 MB ( RDNA 2). Changes were also made in the graphics pipeline, which made it possible to increase the graphics core clocks – for the Radeon 680M, the maximum is 2200 MHz (Ryzen 7) or 2400 MHz (Ryzen 9). At 2400MHz, the computing power of the integrated graphics processing units (iGPUs) is 3.4 TFLOPS (FP32) or 6.8 TFLOPS (FP16). Thanks to the new DDR5 4800MHz and LPDDR5 6400MHz controllers, it was also possible to increase the bandwidth by 50% compared to graphics systems based on Vega architecture and DDR4 / LPDDR4x memory. All of these changes are expected to result in up to two times the gaming performance.

The big advantage of AMD integrated graphics systems is support for AMD FidelityFX Super Resolution 1.0 and 2.0 technology. While the first generation did not offer high-quality graphics, the FSR 2.0 version is much better in this regard. Today we take a look at the performance of the Radeon 680M in a game that uses FSR 2.0. We are talking about God of War, one of the best PlayStation 4 games, which debuted on PC a few months ago. On the surface, the game seems quite demanding for the integrated graphics system, especially with a limited power limit (test was based on the ASUS Zenbook S 13 OLED laptop). We’ll see how FSR 2.0 activation can support iGPU RDNA 2.
