RTX A4000 vs RTX A5000 for rendering
The RTX A5000 has 24 GB of memory, 8,192 CUDA cores and 768 GB/s of memory bandwidth; the RTX A4000 has 16 GB, 6,144 CUDA cores and 448 GB/s (NVIDIA's datasheets). For rendering, memory decides first: if your scene peaks under about 14 GB, the A4000 holds it; between about 14 and 22 GB, you need the A5000. On Coreframe the A4000 is $1.49/hr and the A5000 $2.29/hr, no GST, billed per minute.

Specs from NVIDIA's datasheets for the RTX A4000 and the RTX A5000, read 11 November 2026. FP32 is NVIDIA's peak figure at boost clock. Prices are Coreframe's live rates. On Coreframe both come with 64 GB of system RAM.
Which one for your scene
Open your heaviest project, read Dedicated GPU memory in Task Manager while you orbit and start a render, and add about 2 GB for Windows and the display. How to measure it.
Peak under about 14 GB → RTX A4000 (16 GB) · $1.49/hr
Interiors, a single building without site context, 2K texture sets, stills and short walkthroughs.
Peak about 14 to 22 GB → RTX A5000 (24 GB) · $2.29/hr
4K PBR texture sets, site context with scattered trees and grass, a federated model, Enscape VR (Chaos recommends 12 GB) or Lumion's high-end tier (16 GB or more).
Peak above about 22 GB → RTX 6000 Ada (48 GB) · $5.29/hr
Point clouds, city blocks and large animations that outgrow 24 GB.
Fits in 16 GB and you want more CUDA cores → RTX 5080 · $3.49/hr
10,752 CUDA cores with 16 GB. Our render-time calculator shows an estimate for each card.
What about render speed?
We haven't timed renders on either card ourselves yet, so this page has no speed figures. More CUDA cores, RT cores and memory bandwidth usually mean shorter GPU renders, but how much depends on the renderer and the scene. For a rough estimate based on public benchmark medians, with the assumptions shown, use the render-time calculator. Or run your own scene on both: you pay per minute for the time you use.
Questions
Is the RTX A5000 faster than the RTX A4000 for rendering?
On paper, yes: it has 33% more CUDA cores (8,192 vs 6,144) and 71% more memory bandwidth (768 vs 448 GB/s), per NVIDIA's datasheets. We have not timed renders on either card ourselves, so we don't quote a render-time difference; the render-time calculator gives an estimate from public benchmark medians.
Is 16 GB of VRAM enough for rendering?
For most single-building work, yes: interiors, one building without site context, 2K texture sets and stills usually fit. It stops being enough with 4K texture sets, dense scattered vegetation, a point cloud or a federated model; measure your scene's peak in Task Manager and add about 2 GB of headroom.
When should I pick the RTX A5000 over the RTX A4000?
When your scene's measured peak memory is above about 14 GB, or close enough that it might grow past it. The A5000's 24 GB holds scenes the 16 GB A4000 cannot load; a scene that doesn't fit doesn't render more slowly, it fails or spills to system memory.
How much does it cost to rent an RTX A4000 or RTX A5000?
On Coreframe the RTX A4000 (16 GB) is $1.49/hr and the RTX A5000 (24 GB) is $2.29/hr, no GST, billed per minute from a prepaid wallet. You pick the card each time you start a session.
Do the RTX A4000 and RTX A5000 support hardware ray tracing?
Yes. Both are NVIDIA Ampere workstation cards with second-generation RT cores (48 on the A4000, 64 on the A5000), so GPU path tracers such as Blender Cycles with OptiX, D5 Render, Twinmotion, Enscape and V-Ray GPU can use them.
