The 51RISC GTX 1660 Super is a bit of an odd one to assess for 3D rendering. The Turing architecture without RT cores means no hardware ray tracing and no OptiX support in Blender. You're relying on CUDA for GPU rendering, which works, but you lose the OptiX speed advantage that RTX cards enjoy.
Six gigabytes of GDDR6 on a 192-bit bus is actually a reasonable memory configuration for the price. The wider bus than the RTX 3050 LP gives it slightly better bandwidth characteristics, which helps in texture-heavy rendering scenarios. And the Turing architecture is genuinely efficient and well-optimised across most rendering software.
Here's the honest problem though. At its current price, the 1660 Super doesn't make much sense when newer RTX cards are available for similar or only slightly higher money. The value proposition only really holds if you can find it significantly cheaper, ideally under £100. As a budget 3D rendering card for learning Blender or doing simple product renders, it's functional. As a serious rendering tool, it's showing its age.
The 51RISC brand is less well-known than the big names, which gives some buyers pause. Build quality seems acceptable based on owner feedback, but it's worth noting this is a third-party card rather than a reference design from a major AIB partner.
Pros
- 192-bit memory bus gives decent bandwidth for the price
- 6GB GDDR6 is workable for basic rendering scenes
- CUDA support across most rendering software
- DVI output for legacy monitor compatibility
Cons
- No RT cores means no OptiX or hardware ray tracing
- Turing architecture is ageing for rendering workloads
- Price needs to be significantly lower to justify over RTX alternatives
- Lesser-known brand with limited track record

Best for Absolute Beginners on Legacy Budgets
Price: £149.00 | Rating: ★★★★½ (4.6)
The Sapphire Pulse RX 580 is a card from 2017 that's somehow still on sale in 2026. And look, Sapphire makes good hardware. The Pulse cooler is well-regarded, build quality is solid, and the RX 580 was a genuinely good card in its day. But its day was a while ago.
For 3D rendering, the eight gigabytes of GDDR5 is actually the card's strongest argument. Eight gigs is more than the RTX 3050 LP or the 1660 Super, which means you can load larger scenes without hitting VRAM walls. AMD's OpenCL support in Blender works, and the Polaris architecture is stable and well-understood by the software ecosystem.
The problems are real though. GDDR5 bandwidth is considerably lower than GDDR6, which slows texture sampling and data throughput during renders. There's no hardware ray tracing. The Polaris architecture is not supported by modern AMD rendering accelerators. And the power draw is higher than you'd expect for the performance level, which means more heat and more electricity cost over long render sessions.
If someone handed you one for free, it would be a fine learning card. At £149, it's genuinely hard to justify when the MSI RTX 5050 exists with vastly superior rendering credentials. Only consider this if the price drops dramatically or you find one second-hand for very little.
Pros
- 8GB VRAM allows larger scene loading than some newer budget cards
- Sapphire build quality is reliable
- Dual HDMI outputs for multi-monitor setups
- OpenCL support in Blender and other renderers
Cons
- Polaris architecture from 2017 is genuinely old for rendering
- GDDR5 bandwidth is well below modern standards
- No hardware ray tracing whatsoever
- High power draw relative to performance
- Overpriced at £149 given newer alternatives

Buying Guide: What to Look For in the Best Graphics Cards for 3D Rendering Under £300
VRAM: The Single Most Important Spec
For 3D rendering, VRAM capacity matters more than almost anything else. When your scene exceeds the GPU's VRAM, the renderer either crashes or falls back to CPU, which is dramatically slower. In 2026, 8GB is the practical minimum for serious work. 16GB, as found on the Gigabyte RX 9060 XT, is genuinely excellent at this price point. Don't be seduced by high clock speeds on a card with only 4GB or 6GB of VRAM.
Architecture and Software Support
Nvidia's RTX cards support OptiX in Blender, which is significantly faster than CUDA for path tracing. AMD cards use HIP, which has improved considerably with RDNA 3 and RDNA 4. If you're using Octane Render or Redshift, you'll want Nvidia for CUDA compatibility. For Blender specifically, both AMD and Nvidia are well-supported in 2026. Older architectures like Maxwell (GTX 970) or Polaris (RX 580) lack modern acceleration features and should be avoided for new purchases.
Memory Bus Width and Bandwidth
The memory bus width affects how quickly data moves between the GPU and its VRAM. A 256-bit bus moves more data per clock than a 128-bit bus. Most budget cards in this roundup use 128-bit or 192-bit buses. It's a real compromise, but at this price point it's largely unavoidable. Higher memory speed (GDDR7 vs GDDR6 vs GDDR5) partially compensates for a narrower bus.
Cooling for Sustained Workloads
Gaming benchmarks run for minutes. Rendering runs for hours. A card that's fine for gaming might thermal throttle badly during a long render session, stretching your render times significantly. Full-size cards with dual or triple fan coolers handle this far better than low-profile designs. If you have the case space, always choose a full-size card for rendering work.
Price Brackets to Target
Under £100: The GTX 970 and RX 580 territory. Avoid for serious rendering. Under £200: The RTX 3050 LP and GTX 1660 Super live here. Functional for learning. £200 to £250: The RTX 5050 and RTX 3050 LP at full price. Solid for intermediate work. £250 to £300: The RX 9060 XT and RTX 5060 LP. This is where the best value for rendering sits in 2026.

How We Assessed These Cards
Our assessment of these cards for the Best Graphics Cards for 3D Rendering Under £300 roundup combined spec analysis, owner feedback from verified UK buyers, software compatibility research across Blender, Cinema 4D, and DaVinci Resolve, and thermal performance data from independent benchmarks. We paid particular attention to VRAM capacity, architecture generation, and sustained load behaviour, since rendering is a very different workload from gaming. Cards were ranked primarily on rendering suitability, not gaming performance.

Final Verdict: Best Graphics Cards for 3D Rendering Under £300
The Best Graphics Cards for 3D Rendering Under £300 in 2026 is, without much debate, the Gigabyte Radeon RX 9060 XT GAMING OC 16G. Sixteen gigabytes of VRAM on a modern RDNA 4 architecture at this price is a genuinely unusual combination, and for Blender, DaVinci Resolve, or Cinema 4D rendering work, that VRAM headroom is transformative compared to the 8GB alternatives. If you need Nvidia specifically for CUDA-dependent software, the MSI RTX 5050 8G GAMING OC is the next best choice, with proper cooling and modern RTX features. And if budget is genuinely tight, the 51RISC GTX 1660 Super gets the job done for simple scenes, provided you find it at a sensible price. Whatever you do, skip the GTX 970. It has no place in a 2026 rendering workflow.
