For Cycles GPU rendering, yes, it is the biggest single-card jump available outside professional GPUs. On Blender's own repeatable benchmark, the GeForce RTX 5090 has a median score of about 16,080 on Blender 5.2.0, against 11,553 for the RTX 4090. That's about 39% faster, and about 3.2 times an RTX 3090. A render that took ten minutes on a 3090 would take roughly three on a 5090, provided the scene fits in the card's 32 GB. Where it doesn't, or where your bottleneck is the viewport, simulation or the CPU, the gain is smaller.
What does Blender's repeatable benchmark say?
Blender Open Data collects results from the official Blender Benchmark tool. Every run renders the same scenes (Monster, Junkshop and Classroom) with Cycles, so results from different machines can be compared. The figures below are medians for OptiX rendering, fetched on 6 Nov 2026. They are live numbers and shift slightly as users upload more runs.
| GPU | Blender 5.2.0 median (runs) | Blender 4.5.0 median (runs) | 5090's lead on 5.2.0 |

| RTX PRO 6000 Blackwell Workstation | 17,306 (19) | 16,737 (205) | PRO 6000 is 7.6% ahead |

Source: Blender Open Data, Cycles OptiX, medians grouped by device (fetched 6 Nov 2026). Scores are samples per minute summed across the benchmark scenes; higher is better. Compare only within one Blender version, because scores move between releases. The ratio column is our arithmetic.
Other reviewers agree. Puget Systems measured the 5090 about 35% faster than the 4090 in Blender GPU rendering at launch. Early Open Data results reported by Tom's Hardware put it about 36–37% ahead. The gap has held steady since.
How much time does that save compared with older RTX cards?
Render time scales roughly with the inverse of the score, so the table translates directly into waiting time on the same scene. The figures below are our arithmetic, not measured renders:
- From an RTX 3080 or 3090: a ten-minute frame drops to roughly 2.6–3.2 minutes. This is the upgrade path where a 5090 changes the working day most.
- From an RTX 4090: ten minutes becomes about 7.2. That's worth having for animation, where it adds up across thousands of frames, but not transformative for stills. See RTX 5090 vs RTX 4090.
- From an RTX 5080: the 5090 is about 1.76x faster and doubles the VRAM from 16 GB to 32 GB. Our RTX 5090 vs RTX 5080 post covers the price gap.
Blender Open Data is the fairest way to compare render GPUs: same scenes, same software, thousands of runs. Use it before you trust anyone's chart, including ours.
Does 32 GB of VRAM matter for Blender?
It matters when your scenes are heavy. Cycles needs the scene's geometry, textures and render buffers in GPU memory. Blender's manual says that if a scene doesn't fit, Cycles "will automatically" try to use system memory. That carries a performance cost, but usually still beats rendering on the CPU. A 16 GB card that spills over can lose much of its speed advantage, while a 32 GB card keeps large texture sets, displacement-heavy assets and high-resolution volumes on the GPU.
We haven't found a reliable rule for how many gigabytes a given scene needs, because it varies widely with textures and geometry. The practical test is to watch GPU memory use in your own heaviest file. If it sits near 16 GB on your current card, the 5090's extra headroom is the main reason to upgrade. Memory does not pool across cards either: two GPUs each need their own copy of the scene, because GeForce cards have no NVLink.
What about the viewport, EEVEE and other renderers?
- Open Data measures Cycles only. It has no viewport, EEVEE or multi-GPU tests, and we found no reputable EEVEE benchmark for RTX 50 cards. Viewport responsiveness also depends on the CPU and scene complexity.
- Two GPUs scale less than you'd expect in Cycles. A render-farm vendor's own test of two 5090s scaled only 1.31–1.59x. In OctaneBench, by contrast, two RTX 5080s (1,957) beat one 5090 (1,730) in a single submission. See two RTX 5080s vs one RTX 5090.
- Other renderers caught up after launch. Puget noted that Redshift and Octane didn't support the 5090 at launch. V-Ray RTX showed a 38% gain over the 4090 in Puget's testing. Check your renderer's current support notes before you buy.
How do you benchmark your own upgrade fairly?
- Download the Blender Benchmark launcher and run it on your current card, choosing the same Blender version you'll compare against on Open Data.
- Note the driver. Blender's manual requires driver 575 or newer for OptiX on current releases, and launch-era drivers produced unreliable results.
- Render one of your own heavy production scenes and record time and peak VRAM. That tells you more than any public score.
- Check thermals and power. A 5090 that throttles in a cramped case, or runs a strict power limit, will score below the median. Our posts on undervolting and case fit cover both.
Is a 5090 or an RTX PRO card the better Blender buy?
For a freelancer or a small studio rendering on GPU, the 5090 is the value pick. The RTX PRO 6000 Blackwell is only about 7.6% faster on Open Data. Its case is 96 GB of memory for scenes that don't fit in 32 GB, plus professional drivers and support. The full comparison is in RTX 5090 vs RTX PRO 6000. On price, NVIDIA's US MSRP for the 5090 is still US$1,999, but US street prices ran around US$6,500–8,500 in late October and November 2026 and change weekly.
If your 3D work also runs through a real-time engine, our guide to the RTX 5090 for Unreal Engine 5 covers where 32 GB helps in UE5 scenes and why LED-wall virtual production needs RTX PRO cards with a Sync board.

Frequently asked questions
How much faster is the RTX 5090 than the RTX 4090 in Blender? About 39% on Blender Open Data's Blender 5.2.0 medians (16,080 vs 11,553, fetched 6 Nov 2026). Puget Systems measured about 35% at launch.
What is the most reliable Blender GPU benchmark? Blender Open Data, built from the official Blender Benchmark tool. Every run uses the same scenes and software, and you can filter by Blender version and see how many runs make up each median.
Do two GPUs double Blender render speed? Not usually. A vendor test of two RTX 5090s in Cycles scaled 1.31–1.59x, and each card needs the whole scene in its own memory.
What happens if my scene doesn't fit in VRAM? Cycles tries to use system memory instead. Rendering continues but slows down, though it is usually still faster than CPU rendering, according to Blender's manual.
Is the RTX 5090 worth it over an RTX 3090 for Blender? On Open Data medians it is about 3.2 times faster and has 8 GB more VRAM, so for regular GPU rendering it is a large upgrade.
