The RX 7900M is shaping as much as be a small bombshell within the laptop computer sector. Already, preliminary suggestions on Time Spy confirmed the chip to be sooner than the RTX 4080 Mobile. Now, again on GeekBench 6, the cardboard is quicker than the RTX 4090 Mobile.
RX 7900M, sooner than an RTX 4090M?
As a reminder, with this 7900M, AMD is placing its Navi 31 GPU right into a laptop computer. The chip in query encompasses a complete of 72 compute items for a complete of 4608 stream processors. This is 20% greater than the RX 7800 XT (3840 stream processors). In phrases of frequency, the GPU is rated at 1825 MHz with a lift to 2090 MHz. Finally, this chip might be geared up with 16 GB of GDDR6 VRAM, all on a 256-bit bus. Memory bandwidth will subsequently be 576 GB/s.
Theoretical FP32 efficiency is just about on a par with the 4090M, with 38.5 TFLOP in contrast with 39.7 TFLOP for NVIDIA’s card. Against the 4080M, we’re higher off: 33.8 TFLOP.
In any case, laptops geared up with each AMD and NVIDIA playing cards have been put by their paces on the check bench. For the AMD card, we discover scores of 171,430 pts with the VulkanAPI, whereas the rating falls to 144,611 pts on OpenCL. Compared with the 4090M, the rating is 9% larger with Vulkan, however lags nicely behind with OpenCL (25%).
Clearly, a frequency downside could clarify such a low rating. During the check, the cardboard was working at 1736 MHz. But this will likely even be as a result of driver: extra optimized for Vulkan than for OpenCL!
