16 GB of pro VRAM,
without HBM pricing.

A4000 is the workstation-grade 16 GB card — twice the memory of a 3090, all with ECC, all on certified drivers. Mid-tier in price, no-nonsense in production.

ECC + ISV certs at the pro floor

Single-slot 140 W form factor lets hosts pack four A4000s per workstation, so supply is plentiful and prices stay friendly. Same ISV certifications as A5000/A6000 at a fraction of the rental — the entry point when ECC matters but workloads fit in 16 GB.

Yi-34B QLoRA ~5.8k tok/s

VFX & rendering

16 GB is enough for production-scale Houdini scenes, Blender Cycles with full geometry, and 8K video pipelines. OptiX accelerated.

V-Ray 5 GPU ~1,750 vray

Multi-tenant serving

16 GB hosts 13B FP16 + 7B FP16 on the same card with batched serving. ECC catches the bit flips that crash long-running endpoints.

why A4000

16 GB ECC
at the right price.

When 24 GB is a constraint and you don't need HBM bandwidth, A4000 is the answer. The cheapest path to a single-card 16 GB workstation on the marketplace.

faq

Questions hosts and renters ask.

Why pick an A4000 over a 3070 with similar VRAM?

ECC memory and ISV certification — required for production CAD, V-Ray, and academic ML where bit-flip integrity matters. Single-slot 140 W form factor lets hosts pack 4× A4000 in one workstation chassis. Quieter and lower-power than consumer Ampere.

Why pick an ECC pro card over a consumer 4090 or 5090?

ECC memory catches single-bit errors silently in flight - mandatory for production CAD pipelines, V-Ray and Octane farms, regulated medical or financial ML, and any research where bit-flip integrity affects results. Pro cards (A4000/A5000/A6000/RTX 6000 Ada/A40) also carry ISV certifications consumer cards do not. If your client SLA references ECC or ISV validation, the consumer 4090 disqualifies.

Are these cards ISV-certified for V-Ray, Octane, and SolidWorks?

The NVIDIA RTX A-series and RTX 6000 Ada carry full ISV certifications: V-Ray, Octane, SolidWorks, Rhino, DaVinci Resolve, ANSYS, COMSOL, and the Adobe Creative Cloud chain. Consumer Ada cards (4090/5090) are not on those lists. If your renderer's support matrix excludes GeForce, you need a pro card - which is exactly what CLORE.AI lists in this tier.

Can I run multi-GPU NVLink workloads on pro cards?

Yes - the A5000 and A6000 expose NVLink in pairs (no Switch fabric), giving 112 GB/s peer bandwidth and unified memory across two cards (48 GB on A5000 pair, 96 GB on A6000 pair). Filter by 'NVLink' in the marketplace to find listings. The RTX 6000 Ada and A40 do not have NVLink connectors but pair via PCIe with FSDP.

How do these compare to A100 and H100 for studios?

Pro cards (A6000 / RTX 6000 Ada / A40) give you 48 GB ECC at one-quarter to one-third the rental price of an A100 80GB and one-fifth of an H100. You give up HBM bandwidth and FP8 tensor cores, but for production rendering, virtual workstations, and 13B-34B inference under ECC the pro tier hits the price-performance sweet spot.

Are pro GPUs quieter than 4090s in shared studio environments?

The cards themselves run cooler and quieter at lower TDP - A4000 is single-slot 140W, A5000 is dual-slot 230W, A6000 is 300W with a blower-style cooler designed for rack airflow. CLORE.AI is a remote rental platform, so the noise question only applies to your own studio if you're hosting; pro cards are explicitly the quieter pick there.
