Notes on 13 values — test conditions and caveats
- 1AMD Radeon RX 7900 XTX, Release date: First retail sale December 13, 2022; announced November 3, 2022.
- 2AMD Radeon RX 9070 XT, Launch price: TechSpot reports AMD subsidizes this MSRP with a $50 retailer rebate, so street prices often run higher.
- 3AMD Radeon RX 7900 XTX, Launch price: AMD's launch figure is the SEP (suggested e-commerce price); partner cards often sold higher.
- 4AMD Radeon RX 9070 XT, Boost clock: TechSpot's 2400 MHz figure is AMD's 'game' clock; the boost rating is 2970 MHz.
- 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 XT, Power connectors: Corsair notes a few partner 90-series cards use 12V-2x6; the vast majority use 2x 8-pin.
- 9AMD Radeon RX 7900 XTX, Power connectors: The reference card uses two 8-pin connectors.
- 10AMD Radeon RX 9070 XT, DisplayPort version: TechPowerUp specifies the DisplayPort outputs as UHBR13.5.
- 11AMD Radeon RX 7900 XTX, DisplayPort version: DisplayPort 2.1 runs UHBR 13.5, up to 54Gbps of display link bandwidth per AMD.
- 12AMD Radeon RX 7900 XTX, Hardware encode: AMD's spec table marks 4K H264 Encode, H265/HEVC Encode and AV1 Encode all as Yes.
- 13AMD Radeon RX 7900 XTX, Video encoders: AMD describes a Dual Media Engine, i.e. two encode/decode engines, capable of simultaneous 8K60 HEVC streams.
Graphics Performance and Architecture
The RX 9070 XT runs on the newer Rdna 4 architecture with a boost clock of 2,970 MHz, whereas the older Rdna 3 card operates at 2,500 MHz. Higher clock speeds help push frame rates in demanding titles.
Despite the architectural jump, the RX 7900 XTX packs 6,144 shader cores and delivers 61.4 TFLOPS of FP32 compute. This raw horsepower gives the older card an advantage in heavy compute workloads over the 48.7 TFLOPS of its newer rival.
Memory and Bandwidth
Memory capacity sets a hard ceiling for ultra-high-resolution textures and heavy mod loads. The RX 7900 XTX equips 24 GB of VRAM across a 384-bit memory bus, driving a memory bandwidth of 960 GB/s alongside a 96 MB last-level cache.
By comparison, the RX 9070 XT steps down to 16 GB of video memory on a 256-bit bus. Its memory bandwidth sits at 640 GB/s with a 64 MB cache, making the older flagship better equipped for extreme multi-display resolutions.
Power and System Requirements
Efficiency favors the newer release. The RX 9070 XT draws 304 W and requires a 750 W power supply unit, reducing strain on your system.
The older competitor demands more energy with a 355 W board power and an 800 W recommended PSU. Both cards utilize standard 8-pin power connectors for easy cabling.
Connectivity and Display Outputs
Modern connectivity standards on the RX 9070 XT include PCIe 5.0 support for faster data transfer with compatible motherboards. It also features three DisplayPort outputs and an HDMI 2.1b port.
The RX 7900 XTX relies on PCIe 4.0 and provides two DisplayPort outputs alongside an HDMI 2.1 port, though it maintains support for up to 4 displays.
Pricing and Value
Launch pricing creates a stark division between these options. The RX 9070 XT arrives at a launch price of $599, though retailer rebates may affect street pricing.
The RX 7900 XTX debuted with a $999 launch SEP, placing it firmly in a higher tier of initial cost for buyers prioritizing maximum memory and compute throughput.
The Verdict
Buy the AMD Radeon RX 9070 XT if you want a lower power draw, PCIe 5.0 support, and a modern architecture at a lower price. Buy the AMD Radeon RX 7900 XTX if you need maximum VRAM, broader memory bandwidth, and higher raw compute power for demanding workloads.
