AMD Ryzen 9 7940HS Tested Alongside the Radeon 780M in 3DMark Time Spy
Just a few days past, we covered two benchmarks of AMD’s upcoming Radeon 780M iGPU. While boasting performance numbers similar to an RTX 2050, the generational uplift was rather small. This has been a point of concern amongst many community leakers. Initially, the Radeon 780M based on RDNA3 was tipped to offer performance levels similar to an RX 570. Today, a laptop featuring the highest-end Phoenix Point CPU, the Ryzen 9 7940HS, and the Radeon 780M iGPU has been benchmarked.
Phoenix Point APU Benchmarked
Over at bilibili, as mentioned by HXL, user 金猪升级包 has shared a few benchmarks of the Ryzen 9 7940HS in 3DMark Time Spy. The user wanted to test power efficiency but termed the idea as ‘meaningless’. All RDNA3 GPUs are facing some sort of hardware or driver-related bottlenecks, which are severely throttling the performance. It is not certain if this problem lies within the architecture itself, however, it may be alleviated through driver updates.
The laptop in question features the Ryzen 9 7940HS, as expected alongside the Radeom 780M iGPU. It packs 32GB of DDR5-5600 dual-channel memory. The user explicitly states that a single-rank module will be the best choice using DDR5 RAM.
The Ryzen 9 7940HS manages to push 11343 points which is a respectable score. This is around 15% faster than the Ryzen 9 6900HX, though slower than the Intel i9-12900HK. The total Time Spy score stands at 3146 points. The Ryzen 9 7940HS was clocked as high as 5.24GHz during this benchmark.
The Radeon 780M, on the other hand, scores 2791 points. This is yet again, marginally better than the Radeon 680M. The latter manages to push between 2400–2700 points, with peaks of up to 3000 or more points. The GPU was also clocked at 2.8GHz, though it is advertised to run at 3GHz when paired with the 7940HS.
The second test, where the CPU is locked at 25W, sees the Ryzen 9 7940HS dip to 8448 points. The domino effect carries to the Radeon 780M as well, which drops to 2486 points. That is Radeon 680M levels of performance, or equal to a GTX 1050 Ti (Laptop). The GPU clocks also decrease to 2.36GHz.
Ryzen 7940HS
The Ryzen 7940HS features 8 cores / 16 threads, purely based on the Zen4 architecture. This CPU carries 40MB of total cache, consuming between 35-45W of power. It is rated to run at 4GHz, going as high as 5.2GHz (Which we saw in the tests above).
The Radeon 780M is a GPU integrated into the Ryzen 9 7940HS. Based on the RDNA3 architecture, the 780M packs 12 CUs. It can run at 3GHz when coupled with the Ryzen 9 7940HS, giving you the best of both worlds.
Conclusion
While these benchmarks are clearly not a representation of the final product, AMD still needs to work on its drivers. RDNA3 is a really interesting architecture and was expected to be AMD’s Zen moment. However, unknown issues are causing it to underperform. Even then, we expect the Radeon 780M to hit at least 3000 points consistently on launch. Are you excited about Phoenix Point? Tell us in the comments.
