RTX 3050 6GB vs 8GB — The Cheapest Gaming PC With a Graphics Card (UK 2026)

The NVIDIA GeForce RTX 3050 6GB is now the cheapest way into one of our custom gaming PCs with a dedicated graphics card. Complete builds start at £939 — hand-assembled in the UK, tested before dispatch, with Windows 11, an NVMe SSD, a 3-year warranty and free next-day delivery included. As always, that is £100 below our eBay price.

It sits just below the RTX 3050 8GB (from £975) in our range. This guide covers what the 6GB card is, how it differs from the 8GB version, what it plays, and which CPU to put with it.

RTX 3050 6GB: The Specs That Matter

• 6GB GDDR6 on a 96-bit memory bus
• 2,304 CUDA cores (Ampere architecture)
• 70W total board power — no PCIe power connector needed, so it runs cool and quiet
• NVIDIA DLSS Super Resolution and DLAA for higher frame rates in supported games
• Hardware ray tracing (2nd-gen RT cores)
• NVENC hardware encoding — H.264 and HEVC, useful for OBS streaming and video export

The 70W figure is the quiet advantage here: less heat, less fan noise, and no strain on the power supply. In a build that is already using a fully modular 850W 80+ Gold PSU, the 3050 6GB is about as undemanding as a modern discrete GPU gets.

RTX 3050 6GB vs RTX 3050 8GB — What Actually Differs

They share a name but they are not the same chip. The 8GB card has more cores, a wider memory bus and a higher power budget:

• Memory: 6GB on 96-bit vs 8GB on 128-bit — the 8GB card has more bandwidth as well as more capacity
• Cores: 2,304 vs 2,560 CUDA cores
• Power: 70W vs 130W — the 6GB card needs no power connector
• Price in a complete build: from £939 vs from £975

In practice the 8GB card is the faster of the two, and the extra VRAM gives more headroom for high-resolution textures in newer titles. The 6GB card gives up some of that for a lower price and a much lower power draw. If your budget is the hard limit, take the 6GB; if you want texture headroom for the next few years of releases, the £36 step up to the 8GB version is the better long-term buy.

What the RTX 3050 6GB Plays

This is a 1080p card, and a good one at that resolution:

• Esports (CS2, Valorant, Fortnite, League of Legends, Rocket League): 1080p high settings with plenty of frames for a 144Hz monitor
• AAA single-player: 1080p medium to high, with DLSS on where the game supports it
• Everyday and creative work: smooth multi-monitor desktop, Photoshop, Lightroom, 1080p video editing

What it is not: a 1440p ultra card, and not a ray-tracing showcase. For 1440p, start at the Intel Arc B570 10GB (from £997) or the RTX 5060 8GB (from £1,056), which also adds DLSS 4 Multi Frame Generation.

Which CPU Should You Pair With It?

Cheapest overall: AMD Ryzen 5 5600X — from £939

The AM4 platform with DDR4 memory keeps the total cost down, and the 5600X is still a capable six-core gaming CPU. This is the most affordable complete build with a dedicated graphics card we sell.

Best DDR5 value: AMD Ryzen 5 7400 — from £984

Moves you to the AM5 platform with DDR5 memory and PCIe 5.0 — a longer upgrade path, for £45 more than the AM4 build.

Intel alternative: Core i5-12400F — from £1,032

Six performance cores and strong 1080p gaming, on the LGA1700 platform.

Where It Sits in Our GPU Range

Our entry tiers, cheapest complete build first:

• RTX 3050 6GB — from £939: cheapest discrete GPU, 70W, 1080p
• RTX 3050 8GB — from £975: more VRAM and bandwidth, 1080p high
• Intel Arc B570 10GB — from £997: 10GB, entry 1440p
• RTX 5050 8GB — from £1,018: Blackwell, DLSS 4
• RTX 5060 8GB — from £1,056: GDDR7, comfortable 1440p

Every one of those is the same build quality, the same 3-year warranty and the same free next-day delivery — the only thing that changes is the graphics card.

Frequently Asked Questions

Is the RTX 3050 6GB good for gaming in 2026?

Yes, at 1080p. It runs esports titles at high settings with high frame rates and handles AAA games at 1080p medium to high, especially with DLSS enabled. It is not intended for 1440p ultra or heavy ray tracing.

What is the difference between the RTX 3050 6GB and 8GB?

The 8GB version has 2,560 CUDA cores and a 128-bit memory bus against the 6GB card's 2,304 cores and 96-bit bus, so it is faster as well as roomier. The 6GB card draws only 70W and needs no power connector. In our builds the 6GB starts at £939 and the 8GB at £975.

What is the cheapest gaming PC with a dedicated graphics card?

An AMD Ryzen 5 5600X with the RTX 3050 6GB, from £939 including Windows 11, an NVMe SSD, a 3-year warranty and free next-day UK delivery.

Does the RTX 3050 6GB support DLSS?

It supports DLSS Super Resolution, DLAA and ray reconstruction. DLSS Frame Generation is exclusive to RTX 40 and RTX 50 series cards — for that, look at the RTX 5050 or RTX 5060.
