Notes on 14 values — test conditions and caveats
- 1AMD Radeon RX 9070 GRE, Release date: Chinese retail deliveries began May 8, 2025; the global launch followed at Computex 2026.
- 2AMD Radeon RX 7900 XTX, Release date: First retail sale December 13, 2022; announced November 3, 2022.
- 3AMD Radeon RX 9070 GRE, Launch price: Global launch MSRP $549; Chinese AIB cards started at ¥4,199 (≈$450 per Notebookcheck).
- 4AMD Radeon RX 7900 XTX, Launch price: AMD's launch figure is the SEP (suggested e-commerce price); partner cards often sold higher.
- 5AMD Radeon RX 7900 XTX, Boost clock: Boost is a burst maximum; typical gaming runs near the 2300 MHz game clock.
- 6AMD Radeon RX 7900 XTX, Memory bandwidth: AMD also quotes 3500 GB/s 'effective' bandwidth with Infinity Cache; 960 GB/s is the raw VRAM figure.
- 7AMD Radeon RX 7900 XTX, Recommended PSU: AMD's 800W minimum assumes a Ryzen 9 5900X-class system; other builds may need more headroom.
- 8AMD Radeon RX 9070 GRE, Power connectors: AIB-only card; most listed partner models use two 8-pin connectors (Yeston Sakura variants use three).
- 9AMD Radeon RX 7900 XTX, Power connectors: The reference card uses two 8-pin connectors.
- 10AMD Radeon RX 7900 XTX, DisplayPort version: DisplayPort 2.1 runs UHBR 13.5, up to 54Gbps of display link bandwidth per AMD.
- 11AMD Radeon RX 9070 GRE, HDMI outputs: AMD sells no retail reference card; port counts are for AMD's reference design as listed by VideoCardz.
- 12AMD Radeon RX 9070 GRE, DisplayPort outputs: AMD sells no retail reference card; port counts are for AMD's reference design as listed by VideoCardz.
- 13AMD Radeon RX 7900 XTX, Hardware encode: AMD's spec table marks 4K H264 Encode, H265/HEVC Encode and AV1 Encode all as Yes.
- 14AMD Radeon RX 7900 XTX, Video encoders: AMD describes a Dual Media Engine, i.e. two encode/decode engines, capable of simultaneous 8K60 HEVC streams.
Performance and Architecture
The RX 7900 XTX relies on the RDNA 3 architecture to deliver 6,144 shader cores and 61.4 TFLOPS of FP32 compute. In contrast, the newer RDNA 4 architecture in the RX 9070 GRE steps down to 3,072 cores and 34.3 TFLOPS, though it reaches a higher 2,790 MHz boost clock.
For buyers prioritizing sheer rendering capability and heavy computational workloads, the RX 7900 XTX holds a substantial advantage.
Memory and Bandwidth
Memory configuration heavily favors the older flagship card, which packs 24 GB of GDDR6 video memory across a 384-bit bus. This yields a massive 960 GB/s raw bandwidth alongside a 96 MB last-level cache.
The RX 9070 GRE cuts these figures in half with 12 GB of VRAM, a 192-bit bus, 432 GB/s bandwidth, and a 48 MB cache. Creators and gamers working at high resolutions will find the extra headroom on the RX 7900 XTX essential.
Power and Efficiency
Energy usage leans heavily toward the newer card, which demands a modest 220 W board power and requires only a 650 W power supply. The RX 7900 XTX requires a much heftier 355 W board power and an 800 W PSU.
Choosing the RX 9070 GRE saves system builders from needing a massive power upgrade and reduces overall heat output in standard desktop chassis.
Connectivity and Features
The RX 9070 GRE brings modern interface updates, including PCIe 5.0 support and HDMI 2.1b alongside three DisplayPort 2.1a outputs. The RX 7900 XTX relies on PCIe 4.0, HDMI 2.1, and two DisplayPort 2.1 ports.
While both cards support hardware encoding for H.264, HEVC, and AV1, the RX 7900 XTX uniquely includes dual media encoders for simultaneous 8K60 HEVC streams.
The Verdict
Buy the RX 9070 GRE if you want a lower power draw, PCIe 5.0 support, and a budget-friendly price tag. Buy the RX 7900 XTX if you need maximum compute power, dual media encoders, and 24 GB of VRAM for demanding workloads.
