AMD Radeon 780M Integrated RDNA3 GPU Finally Breaks 3K Points On TimeSpy –

AMD Radeon 780M gets a quick memory boost

Chinese tech critic Golden Pig Upgrade shares new 3DMark scores with integrated RDNA3 GPU.

A growing body of data suggests that the Radeon 780M, the RDNA3 integrated GPU in AMD Phoenix APUs, will benefit greatly from fast memory. However, this shouldn’t surprise anyone because system memory is usually the biggest bottleneck for integrated graphics. This new AMD APU officially supports up to DDR5-5600 and LPDDR5x-7500, but so far we haven’t seen any tests with LPDDR5 memory.

On Bilibili there is a screenshot that supposedly shows the Radeon 780M iGPU being tested with 3DMark Time Spy. Assuming this is an actual screenshot with the AMD Phoenix APU for laptops, this would be the first time we’ve seen a 3K graphics score on this processor:

At over 3K points, the iGPU comes very close to the GTX 1650 Ti, but there’s still a chance we’ll see it score higher. After all, the APU still supports faster LPDDR5X memory.

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

The Radeon 780M iGPU has 12 compute units, as many as the last generation Radeon 680M, which was part of the Ryzen 6000 mobile series. This new score compared to the faster 680M implementation shows 23% better performance.

Officially, AMD Ryzen 7000HS laptops should start shipping this month, however we haven’t seen any for sale yet.
