In today article, I try to dive into a comprehensive breakdown of what the RTX 5090 brings to us, how it performs in theory and in reality compared to its predecessor - the RTX 4090, and whether you should invest in it based on its 3D rendering capabilities.
Hardware Brief // RTX 5090 vs RTX 4090 for 3D Rendering
This brief explains whether the RTX 5090 for 3D rendering is worth buying in Blender, V-Ray, Redshift and Octane, using published reviews from Puget Systems and CG Channel and NVIDIA’s own specifications.
- Raw Speed: Puget Systems measured the RTX 5090 about 35% ahead of the RTX 4090 in Blender 4.0 and about 38% ahead in V-Ray 6, and CG Channel found it won every GPU rendering test it ran.
- The VRAM Factor: 32 GB versus 24 GB is the most practical reason to buy it, because a scene that fits in memory renders far faster than one that spills out of the GPU.
- Power and Price: NVIDIA lists 575 W and $1,999 at launch; CG Channel saw street prices near $3,000 in late 2025 and called anything above about $2,500 hard to justify.
- Production Verdict: Buy it if your scenes regularly exceed 24 GB; otherwise a used RTX 4090 or rented GPU time is usually better value. Our render farm ranking covers the rental route.
The RTX 5090 for 3D rendering is the fastest consumer GPU NVIDIA has released, but it is not the better buy for everyone. Reviews measured it roughly 35% to 38% faster than the RTX 4090 in the apps they could test, and its 32 GB of memory matters more than its core count if your scenes are large. This article was first written in April 2025 and rewritten in October 2026 using later benchmark data.
How much faster is the RTX 5090 for 3D rendering than the RTX 4090?
In published tests the RTX 5090 for 3D rendering is about 35% to 38% faster than the RTX 4090 in GPU renderers that supported it at launch. That is a solid generational step, but smaller than many buyers expected from the core-count increase.
| Test (source) | RTX 5090 vs RTX 4090 | Notes |
|---|---|---|
| Blender 4.0 GPU rendering (Puget Systems, Jan 2025) | About +35% | Ryzen 9 9950X platform, early drivers |
| V-Ray 6.00.01 RTX score (Puget Systems, Jan 2025) | About +38% | Puget flagged a known V-Ray CUDA issue, so treat with caution |
| Unreal Engine 5.5 geomean FPS (Puget Systems, Jan 2025) | About +17% overall, +19% ray traced | Real-time, not offline rendering |
| GPU rendering suite incl. Arnold, Blender 4.4, Redshift, V-Ray GPU 7, OctaneBench (CG Channel, Dec 2025) | 5090 won every test | Published as charts, no single percentage |
Two limits apply. Puget could not test Redshift or OctaneBench in January 2025 because neither supported the card yet, so those early numbers say nothing about them. CG Channel’s later review covers both but publishes the results as charts, so we do not quote a percentage for them. Check the CG Channel review for the exact bars.
RTX 5090 for 3D rendering: specs compared with the RTX 4090
The RTX 5090 has about 33% more CUDA cores, 33% more memory and 78% more memory bandwidth than the RTX 4090, but it also draws more power. Figures below are NVIDIA’s launch specifications.
| Spec | RTX 5090 | RTX 4090 |
|---|---|---|
| Architecture | Blackwell | Ada Lovelace |
| CUDA cores | 21,760 | 16,384 |
| Memory | 32 GB GDDR7, 512-bit | 24 GB GDDR6X, 384-bit |
| Memory bandwidth | 1,792 GB/s | 1,008 GB/s |
| Total graphics power | 575 W | 450 W |
| Launch MSRP | $1,999 | $1,599 |
A spec sheet is not a render time. The 33% core increase came with a 35% to 38% rendering gain in the tests above, which suggests these cards scale roughly with cores in those renderers, but that is our reading of two data sources, not a controlled experiment. Manufacturer figures are on the NVIDIA RTX 5090 page.
Does 32 GB of VRAM change what you can render?
Yes. Extra VRAM decides whether a scene renders at full speed at all, which is a bigger practical effect than a 35% speed gain. When a scene exceeds GPU memory, renderers either stop with an out-of-memory error or fall back to slower out-of-core paths.
CG Channel’s review gives two concrete cases. In its V-Ray tank scene, GPUs with more than 16 GB rendered much faster than smaller cards, and its Cinema 4D Pyro simulation needed about 30 GB, so only the RTX 5090 and older professional cards with large memory were usable for production. If your work looks like that, 32 GB is the reason to buy. If your scenes fit in 24 GB, you are paying for speed alone. For the failure modes, see what actually causes CUDA out-of-memory errors, what to do when a scene needs more VRAM than you have and how VRAM and system RAM differ by render engine.
What does the RTX 5090 for 3D rendering cost to run?
The card costs more to buy and more to power. NVIDIA lists 575 W against 450 W, a 28% higher power budget for a 35% to 38% gain in the tests above. That is a specification comparison, not a measured efficiency result, because Puget did not publish measured power draw.
Price is the larger issue. CG Channel recorded online prices around $3,000 in late 2025, down from more than $4,000 a few months earlier, against a $1,999 launch MSRP, and said anything above about $2,500 is hard to justify. Used RTX 4090 cards were selling for roughly $1,700 to $2,000 at the same time. Street prices move quickly, so check current listings before you decide. You also need a power supply and case that can handle the card; Puget tested on a 1600 W unit.
Should you buy an RTX 5090 for 3D rendering or rent GPU time instead?
Buy if you render large scenes most days and the card will stay busy. Rent if your heavy renders come in bursts. A simple break-even check: card price plus any power supply and system upgrades, divided by the hourly price of a rented equivalent, gives the number of render hours before owning wins.
As an illustration only, if a card costs $3,000 and comparable rented time costs $1.50 per hour, owning breaks even after 2,000 render hours, before electricity. Replace both numbers with real quotes. Services also differ in what they rent: some are automated render farms, others give you a full remote GPU machine with your own software. Our top 10 render farms ranking compares these models, and our GPU and CPU guide covers the rest of the hardware you would need to match.
Who should buy the RTX 5090 for 3D rendering?
| Your situation | Better choice |
|---|---|
| Scenes regularly exceed 24 GB (heavy simulation, large V-Ray or Redshift scenes) | RTX 5090, or rented high-memory GPUs |
| Scenes fit in 24 GB and you render daily | A used RTX 4090 at a lower price, if you can find a reliable one |
| Heavy renders only near deadlines | Rent GPU time and keep your current card |
| Street price above about $2,500 | Wait or compare, in line with CG Channel’s value view |
Our reading, based on the reviews above: the RTX 5090 for 3D rendering is a strong buy for memory-bound work and a hard sell for scenes that already fit on a 4090. That is an interpretation of other people’s measurements, not a result from our own test bench.
FAQ
Is the RTX 5090 worth it for Blender?
Puget Systems measured about 35% faster Blender 4.0 GPU rendering than the RTX 4090. It is worth it if you also need the extra memory or render all day; otherwise a cheaper card or rented time is usually better value.
How much VRAM does the RTX 5090 have?
The RTX 5090 has 32 GB of GDDR7 memory on a 512-bit bus, compared with 24 GB of GDDR6X on the RTX 4090.
Does the RTX 5090 work with Redshift and Octane?
Not at the time of Puget Systems’ January 2025 test. CG Channel’s December 2025 review ran Redshift for 3ds Max 2025.6.0 and OctaneBench 2025.2.1 on it, so those versions support the card. Check your renderer’s release notes for your version.
What power supply does an RTX 5090 need?
NVIDIA lists 575 W total graphics power. Puget tested with a 1600 W supply; confirm NVIDIA’s current recommendation for your full system before buying.
