Stable Diffusion GPU VPS in Romania Without KYC

Stable Diffusion 1.5 at 512x512 fits in 4GB of VRAM with xformers attention enabled. SDXL at 1024x1024 needs 10-12GB for base plus refiner. SD3 medium at 1024x1024 sits around 12-14GB. Flux.1-dev at full FP16 wants 24GB and is the reason most artists target the RTX 4090 specifically.

Our Romania GPU VPS ships with the full 24GB available to the guest, not partitioned. You can run Flux.1-dev plus a ControlNet plus a LoRA on the same card without offloading to system RAM. ControlNet adds roughly 1.5GB per active preprocessor. LoRAs add 100-400MB each loaded into the UNet.

For batch generation, a single RTX 4090 produces roughly 25-30 SDXL images per minute at 30 steps with the DPM++ 2M Karras sampler. ComfyUI batching pushes that to 35+/min if you queue prompts efficiently.

We currently stock RTX 4090 24GB (24576 MB GDDR6X, 16384 CUDA cores) and RTX 3090 24GB (10496 CUDA cores) in our Bucharest location. Both ship with PCIe 4.0 passthrough on AMD EPYC host platforms. The 4090 is roughly 1.7x faster than the 3090 on SDXL inference; the 3090 is the better value if you generate continuously rather than burst.

System spec around the GPU: 8 dedicated vCPU on EPYC Genoa or Milan, 32GB DDR4 ECC RAM, 500GB NVMe SSD for models and outputs, 1Gbps unmetered network. Plenty of bandwidth to push generated images to an S3-compatible bucket or to your own Tor onion service.

If you outgrow a single 4090 we offer 2x4090 dedicated boxes on request. Dual 4090 is the sweet spot for FluxControl training runs or for running an SDXL inference API at production volume.

A 4090 sustains 450W under continuous SDXL generation. Our Romania racks run on N+1 PDU redundancy and active liquid-assisted air cooling per chassis. We do not throttle GPUs to manage thermals - the cards run at their stock boost clocks 24/7 and we have telemetry showing 0.5C ambient variance at the GPU intake across the day.

For training runs (Dreambooth, LoRA fine-tuning) where the GPU sits at 100% for 6-12 hours, you do not need to babysit thermals or worry about a noisy datacenter. Our SLA covers sustained load explicitly; we do not have a fair-use clause that punishes you for actually using the card.

Pick at checkout: ComfyUI with Manager, ComfyUI Impact Pack, custom node ecosystem pre-installed; or Automatic1111 with the most-installed extensions (ControlNet, ADetailer, Regional Prompter, Dynamic Prompts). Both ship with a working PyTorch 2.3 + CUDA 12.4 environment, xformers compiled for the 4090, and SDXL base + refiner pre-downloaded.

You get root on the box. Wipe our image and install Stable Diffusion WebUI Forge, InvokeAI, Fooocus, or roll your own diffusers script - we do not lock the GPU behind a managed UI. The only restriction is no CSAM and no deepfake-non-consensual generation, which we enforce by abuse policy not by content filtering on your prompts.

Sign up with email only, no ID, no phone verification. Pay in BTC, XMR, LN, USDT or LTC. Provisioning runs as soon as the on-chain confirmation lands (12 minutes for BTC on default 1-conf, sub-minute for LN, 2 confirmations for XMR). Reverse DNS is configurable to a generic hostname; the IP is dedicated.
