## Description

SAPPHIRE PULSE AMD RADEON™ RX 6400 GAMING 4GB GDDR6 HDMI / DP LP LITE

Review: Great option for a graphics boost to mini/small form factor PCs where space is tight - If you have a small form factor/mini desktop PC and want to add a GPU to beef up its graphics capability there are very few graphics card options that will fit in the tight space available. Luckily this low profile RX 6400 card is readily available for a reasonable price and will readily fit in most SFF cases that have a single free PCI slot. Sure, the RX 6400 might not perform very well when compared against better specified, bigger, much pricier cards but since installing (very easily) this card in my DeskMini AMD Ryzen 5 5600g I’ve had no problems playing Red Dead Redemption 2 at 1080P with medium settings - that’s good enough performance for me, especially at the price paid for the card. I reckon the RX 6400 has at least doubled the performance of the CPU’s integrated Vega graphics I was relying on before, for a little over 100 pounds paid. Highly recommended for the right use case (mini/small case PCs with no GPU and a suitable motherboard with a PCI slot), but don’t expect it to be able to play more recent AAA games smoothly - it’s not a graphics powerhouse.
Review: Good enough for smooth gaming - A good price by performance value graphics card. Easily fitted inside my Dell Optiplex 7020 SFF DESKTOP computer in a single slot. The performance is not bad considering this GPU is now getting old but I got 60FPS on most of the modern games as well 1080p with Maximum settings.

### ⭐⭐⭐⭐⭐ Good enough for smooth gaming
*by A***N on 20 July 2025*

A good price by performance value graphics card. Easily fitted inside my Dell Optiplex 7020 SFF DESKTOP computer in a single slot. The performance is not bad considering this GPU is now getting old but I got 60FPS on most of the modern games as well 1080p with Maximum settings.

### ⭐⭐⭐⭐ Does everything it's supposed to. No retaining screw
*by O***I on 24 February 2025*

It fits my Acer 1780 XC and works fine (although I did need to beef the power supply to 300W). Really happy with it except it doesn't come with a retaining screw - a really odd and irritating omission. It means you're going to need to add a few quid to the price to pay for a pack of screws, nearly all of which you won't need. As I say, oddly irritating, when Sapphire could easily bundle a single one with all of the other bits and pieces.
