The ASUS Prime GeForce RTX 5080 OC 16G is the fifth card in this guide and sits mid-field on price: £1,399.99, which is £110 more than the cheapest card here and £364.75 less than the dearest. It is a PCIe 5.0 card with 16 GB of GDDR7, AI performance quoted at 1801 AI TOPS, one HDMI 2.1b and three DisplayPort 2.1b outputs, and a 2.5-slot cooler using Axial-tech fans and a vapour chamber.

What stands out on this listing is the memory clock. The spec table's Memory Clock Speed field reads 2615 GHz, roughly a thousand times the 2655 MHz the same table gives for the GPU clock. The bullets also disagree with the table on the boost figure: ASUS's own bullet says 2685 MHz in OC mode and 2655 MHz in default mode, while the spec table's GPU Clock Speed field lists 2655 MHz. Both can be read as correct depending on which mode is running, but they are printed as though they were the same measurement. The section below also lists the card as compatible with a laptop. Everything on this page comes from the Amazon listing, not from any testing of our own.

## Questions people ask

**What memory clock does the ASUS Prime RTX 5080 OC list?**

The spec table's Memory Clock Speed field reads 2615 GHz. That sits on the same page as a 2655 MHz GPU clock, so the two figures are about a thousand times apart — treat the memory figure with caution rather than as a measured speed.

**What clock speed does the ASUS Prime RTX 5080 OC run at?**

ASUS's bullet says OC mode boosts the clock to 2685 MHz and default mode runs at 2655 MHz. The spec table's GPU Clock Speed field lists 2655 MHz, the default figure, so the two fields differ by 30 MHz depending on which one you read.

**How much memory does the ASUS Prime RTX 5080 OC have?**

16 GB, listed as GDDR7 in the Graphics Card Ram Type field and described in the product title as 16G GDDR7.

**What outputs does the ASUS Prime RTX 5080 OC have?**

One HDMI 2.1b and three DisplayPort 2.1b, with a listed maximum resolution of 7680 x 4320.

**Will the ASUS Prime RTX 5080 OC fit a small case?**

The listing calls it an SFF-Ready Enthusiast GeForce Card and describes a 2.5-slot cooler with a vapour chamber, Axial-tech fans and Dual BIOS.

**What did buyers say they paid?**
