XFX Radeon RX 7900 GRE

Manufacturer: XFX

The XFX Radeon RX 7900 GRE is a graphics card based on AMD's RDNA 3.0 architecture, manufactured on a 5nm process and housing 57,700 million transistors. It operates with a base GPU clock of 1705 MHz and a boost clock reaching up to 2395 MHz, with 49.05 TFLOPS of floating-point performance available for demanding workloads. The card measures 335mm in length and 130mm in height, carries a 3-year warranty, and does not include RGB lighting.

On the memory side, the card is equipped with 16GB of GDDR6 VRAM across a 256-bit bus, delivering a maximum bandwidth of 576 GB/s at an effective speed of 18,000 MHz. It includes 5,120 shading units, 320 texture mapping units, and 160 render output units, yielding a texture rate of 766.4 GTexels/s and a pixel rate of 383.2 GPixels/s. Feature support covers DirectX 12 Ultimate, OpenGL 4.6, OpenCL 2.2, ray tracing, AMD SAM, ECC memory, and multi-display output across up to four screens via one HDMI 2.1 port and three DisplayPort outputs. The card connects via PCIe 4.0 and has a rated TDP of 260W.

Pros

16GB of GDDR6 VRAM across a 256-bit bus provides substantial memory capacity for high-resolution and memory-intensive workloads
A maximum memory bandwidth of 576 GB/s supports fast data throughput between the GPU and its memory pool
Ray tracing support is included, enabling hardware-accelerated lighting and shadow rendering
Supports up to four simultaneous displays through a combination of three DisplayPort and one HDMI 2.1 output
AMD SAM is supported, allowing the CPU to access the full GPU memory pool for improved data transfer efficiency
ECC memory support adds a degree of data integrity protection suited to precision-sensitive tasks

Cons

A 260W TDP places meaningful demands on system power delivery and case airflow
No USB-C or DVI outputs are available, limiting connectivity options for users with older or specialized monitors
DLSS and XeSS are not supported, leaving the card without AI-based upscaling options from those ecosystems
At 335mm in length, the card requires a sufficiently spacious case to fit without obstruction
Air-water cooling is not included, so thermal management relies entirely on the installed air cooler

Who is this for?

This card is well-suited to users running high-resolution or multi-monitor setups, given its 16GB of GDDR6 VRAM, 576 GB/s memory bandwidth, and support for up to four simultaneous displays. The inclusion of ray tracing, DirectX 12 Ultimate, and AMD SAM makes it a reasonable fit for those engaged in graphically demanding rendering or compute workloads, while ECC memory support adds appeal for users who require data integrity in precision-sensitive tasks such as 3D content creation or technical computation.

Who is this NOT for?

Users working in compact or small-form-factor builds may find the 335mm card length and 260W TDP difficult to accommodate without careful planning around case space and power delivery. Those who rely on AI-based upscaling technologies such as DLSS or XeSS will find no support for either here, making it a poor fit for workflows or gaming scenarios built around those ecosystems. Additionally, users needing USB-C or DVI display connectivity will need to look elsewhere, as neither output type is available on this card.
