Foreign technology media tomshardware recently launched a video encoding test of AVC, HEVC and AV1, and the results showed that AMD GPU still lags behind Nvidia and Intel.
The 13th-generation platform attached to this test is as follows:
Processor: Intel Core i9-13900K
Motherboard: MSI MEG Z790 Ace DDR5
Memory: G.Skill Trident Z5 2 x 16GB DDR5-6600 CL34
Hard Drive: Sabrent Rocket 4 Plus-G 4TB
Power supply: 1500W Dark Power Pro 12
Radiator: Cooler Master PL360 Flux
System: 64-bit Win11 Professional Edition
Gen 12 Test Platform:
Processor: Intel Core i9-12900K
Motherboard: MSI Pro Z690-A WiFi DDR4
Memory: Corsair 2x16GB DDR4-3600 CL16
HDD: Crucial P5 Plus 2TB
Radiator: Cooler Master MWE 1250 V2 Gold
System: 64-bit Win11 Professional Edition
Test graphics card:
Nvidia: RTX 4090, RTX 3090, GTX 1650
Intel: A770, integrated UHD 770 graphics
AMD: RX 7900 XTX, RX 6900 XT, RX 5700 XT, RX Vega 56, and RX 590
Test Results:
AV1 encoding test results are not much different from HEVC encoding, and the only advantage of AV1 is that it is royalty-free.
Nvidia Ada Lovelace NVENC hardware performs best and is currently only equipped on RTX 4070 Ti and higher GPU models.
Intel’s Arc GPUs also offer great quality and performance for streaming purposes. However, Nvidia graphics cards offer richer adjustment options and more software support.
AMD GPU is still behind the two competitors. The RDNA 3-based RX 7900-series graphics cards performed best, but performed about as well as the GTX 10-series from 2016 when it came to video encoding.
