The Best GPU for Gaming
From the ROG Astral 5080 White to the ROG Astral 5090: five graphics cards ranked on video memory and GPU, with who should skip each one.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated
For gaming, the GPU is the part to spend on first. This set runs from the high end down.
Our comparison rests on published figures for GPU, VRAM and memory; nothing here was tested in-house, and where a maker leaves out boost clock, we say so.

How We Chose
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- What we compared
- We set side by side five cards on GPU, video memory, memory and boost clock from manufacturer specifications. We did not test them in-house, and boost clock and outputs are missing for at least one pick.
- The shared baseline
- All 5, from the ROG Astral 5090 to the ROG Astral 5080 White, state GPU, video memory and memory.
- Where the specs have gaps
- The ROG Astral 5090, the ASUS TUF RTX 5090 and the ROG Strix 4090 give no boost clock; the ROG Strix 4090, the MSI 4090 Gaming X Trio and the ROG Astral 5080 White give no outputs.
- Price range
- From the ROG Astral 5080 White to the ROG Astral 5090, all sat in the over $1500 tier when we checked.
