AMD Radeon 780M gets fast memory boost

Chinese tech reviewer Golden Pig Upgrade shares new 3DMark scores featuring integrated RDNA3 GPU.

More and more data suggests that Radeon 780M, the RDNA3 integrated GPU into AMD Phoenix APUs, will heavily benefit from fast memory. However, this shouldn’t surprise anyone because system memory is often the biggest bottleneck for integrated graphics. This new AMD APU officially supports up to DDR5-5600 and LPDDR5x-7500, but thus far we have not seen any tests with LPDDR5 memory.

Over at Bilibili there is a screenshot allegedly showing the Radeon 780M iGPU being tested with 3DMark Time Spy. Assuming that this is a real screenshot featuring the AMD Phoenix APU for laptops, this would be the first time we see 3K graphics score on this processor:

With over 3K points, the iGPU gets very close to GTX 1650 Ti, but there is still a chance we will see it with higher scores. After all, the APU still supports faster LPDDR5X memory.

As mentioned, this iGPU can have either 2.7 GHz or 2.8 GHz frequency, depending on whether this is Ryzen 9 7940HS or Ryzen 7 7840HS. Both are 8-core APUs with Zen4 architecture and RDNA3 graphics, but they have slightly different clocks (Ryzen 9 should be 100 MHz faster).

The Radeon 780M iGPU has 12 Compute Units, just as many as the last gen Radeon 680M which was part of the Ryzen 6000 mobile series. This new score compared to the fastest implementation of 680M shows a 23% higher performance.

Officially, AMD Ryzen 7000HS laptops should start shipping this month, however we have not seen any on sale yet.
