•Memory bandwidth at 800GB/s & 960GB/s on Xt & Xtx respectively (according to amd product pages)
•7900xt features 20GB Gddr6 vram on a 320bit bus, 24GB and 384bit bus on 7900xtx
•Second gen infinity cache
•Faster interconnect bandwidth (Up to 5.3 TB/s)
•80 & 96MB of infinity cache on 7900Xt & 7900Xtx respectively
•Costs between 899 & 999(600-700 dollars cheaper than 4090)
•New/faster display/media engine(Radiance Display Engine, dual media engine up to 7x faster)
•Optimised performance for some encoding/streaming apps(Obs, ffmpeg, Premiere ,handbrake. More apps soon)
•1.54x improvement in perf/watt over rdna2
•New dedicated Ai accelerators with 2.7x ai improvement over rdna2(2 ai acceleration units in each cu)
•1.5x higher rt performance compared to previous high end flagship(rt performance can be up to 1.8x higher)
•Total board power at 320w for 7900xt & 355w for 7900xtx respectively
•New adrenalin software with more unified features
•Sneak peak at Fsr3.0 with new frame doubling feature
Small correction(Thanks AncientOrigin for the input):
The 7900Xt has a total board power of 300w, not 320w like on one of my bullet points . Thanks for the correction guys!
