AMD Radeon RX 7900 XTX
Released in December 2022 with a $999 launch price, the AMD Radeon RX 7900 XTX is a high-performance graphics card built for enthusiasts seeking powerful rendering capabilities. It utilizes advanced Rdna 3 architecture to handle demanding gaming workloads.
- Release date
- 2022-12
- Launch price
- 999 USD
- Shader cores
- 6,144 cores
- Video memory
- 24 GB
- Memory type
- Gddr6
- Memory bus width
- 384 bit
Performance and Compute Power
The card relies on 6,144 shader cores to deliver a burst maximum of 2,500 MHz, though typical gaming runs near the 2,300 MHz game clock. This processing engine yields 61.4 TFLOPS of FP32 compute capability, giving the RX 7900 XTX heavy lifting power for complex graphics tasks.
Buyers get fast instruction execution for high framerates at top resolutions without stuttering.
Memory and Caching
With 24 GB of Gddr6 video memory across a 384-bit memory bus, the card moves data at 20 Gbps. It hits a raw VRAM figure of 960 GB/s, alongside an effective bandwidth of 3,500 GB/s powered by its 96 MB last-level cache.
This deep memory pool prevents bottlenecks when loading massive texture packs in modern titles.
Power and System Demands
Operating at a board power of 355 W, the hardware requires an 800 W recommended power supply unit, assuming a Ryzen 9 5900X-class system. The reference version draws power using two 8-pin connectors over a PCIe 4.0 interface with 16 lanes.
Builders must check that their current power supply and case clearance fit these strict electrical and physical demands.
Display Outputs and Video Engine
Connectivity includes one HDMI 2.1 port and two DisplayPort 2.1 outputs supporting up to four simultaneous displays. The dual media engine handles hardware encode for H.264, HEVC, and AV1 formats.
Streamers and multi-monitor users gain crisp output options and simultaneous 8K60 HEVC stream handling.
