**Direct answer:** For cloud workloads, cpu vs gpu comes down to workload shape: CPUs handle sequential, general-purpose and integer-heavy work such as web serving, databases, app dev/test and virtualization, while GPUs handle parallel work such as AI training and inference. LayerStack addresses both with [Premium Compute VM](https://www.layerstack.com/en/premium-compute) powered by 5th Gen AMD EPYC 9745 processors for premium CPU compute, and [Nano Cloud GPU](https://www.layerstack.com/en/cloud-gpu) with NVIDIA A40, A100 and RTX5090 options starting at US$5.00/mth total monthly fee for GPU-accelerated work.

## cpu vs gpu: what each processor does best

CPUs execute a small number of complex, sequential threads with strong single-thread and integer performance. GPUs execute thousands of smaller parallel threads simultaneously.

In practice for cloud servers:

- **CPU compute is for:** operating systems, web requests, application logic, databases, analytics queries, virtual desktop infrastructure (VDI), VM density, media streaming control planes, and enterprise applications where latency per task and compatibility matter.
- **GPU compute is for:** model training, fine-tuning, AI inference at scale, image/video generation, and other parallel math where throughput across many cores matters.

LayerStack documents this split directly in its product lines: Premium Compute VM is described as optimized for advanced AI, cloud-native applications, and enterprise computing with extreme processing power, while Nano Cloud GPU is described as designed to accelerate AI development with isolated GPU environments and intelligent scheduling.

## gpu vs cpu: when to choose a Cloud GPU

Choose GPU when the workload is parallel and GPU-accelerated, and remains on GPU for sustained execution time.

LayerStack Nano Cloud GPU specifications listed:

- GPU options: NVIDIA A40, NVIDIA A100, NVIDIA RTX5090
- Attached resources listed: vCPU: AMD EPYC 2.7GHz, Memory: 96GB, Storage: 50GB, Transfer: 1TB
- Estimated usage rate: US$0.24/hr for usage hours
- Pricing model: Basic Monthly Fee + GPU Usage Fee, with total monthly fee starting at US$5.00
- Billing: hourly billing, no minimums, prepaid wallet with auto-refill, real-time tracking, low-balance alerts, invoice history, and early-term credits where unused time is refunded
- Architecture: microservice architecture for instant access to isolated GPU environments, multi-user sharing on hardware, and pay stops on pause or scale

Stated positioning is 70% below market price and cost-effective multi-tenant GPU sharing for Asia-Pacific developers with low-latency access. Use GPU for training runs, batch inference, and development where task-only full GPU resources on demand reduce the need to pay for 100% of the time.

Choose CPU instead when the code is not GPU-accelerated, when data movement to GPU would exceed compute time, or when cost per vCPU, memory size, and storage I/O are the constraints. Those workloads run on Premium Compute.

## When premium CPU compute wins

Premium Compute VM uses 5th Gen AMD EPYC 9745 Turin processors on 4 nm technology with:

- 192 cores per processor
- 33% more vCPUs stated for cloud VMs
- Up to 2.7x higher integer performance vs competitors stated for AI inference performance
- Support for DDR5 SDRAM
- PCIe 4.0 NVMe SSD storage

LayerStack lists best uses as Analytics, App dev/test, HPC, media streaming, VDI, VM Density, Web Serving, and CDC.

Listed Premium Compute plans for SG and HK:

| Plan | RAM | vCPU | Storage | Price |
|---|---|---|---|---|
| PRO200 | 8GiB RAM | 4 vCPU | 200GiB PCIe 4.0 NVMe SSD | US $28.00 /mth |
| PRO300 | 16GiB RAM | 8 vCPU | 300GiB PCIe 4.0 NVMe SSD | US $57.00 /mth |
| PRO600 | 32GiB RAM | 16 vCPU | 600GiB PCIe 4.0 NVMe SSD | US $148.00 /mth |

Storage performance context: LayerStack NVMe documentation states NVMe SSD transfers 25 times more data than SATA SSD by using PCIe sockets, commands are 2 times faster than AHCI drives, and input/output operations per second exceeds 1 million and is up to 900% faster than AHCI drives. This matters for database, analytics, and web-serving workloads where I/O consistency and lower latencies via PCI Express affect throughput.

## amd epyc 9754: where the 4th Gen Bergamo fits

The query amd epyc 9754 refers to LayerStack cloud servers powered by 4th Gen AMD EPYC 9754 Bergamo processors, codenamed Bergamo.

Documented specifications:

- Up to 128 cores and 256 threads per socket
- Up to 128 cores per server stated for LayerStack deployments, with a dozen DDR5 memory controllers
- Zen 4 core architecture
- AMD Infinity Guard security feature set
- Positioning for HPC, web, gaming and database servers and other CPU-intensive applications

The 5th Gen AMD EPYC 9745 used in Premium Compute VM is the newer Turin generation, with 192 cores stated vs 128 cores for the 9754, and the stated 33% increase in vCPUs and 2.7x integer performance uplift. In selection terms: use 9754-based CPU compute for established high-core-count, memory-bandwidth-sensitive web, database and HPC needs, and use 9745-based Premium Compute VM where higher vCPU density and integer throughput per VM are required.

## How to choose for your workload

- If workload uses frameworks that schedule to GPU and runs parallel math for minutes to hours: evaluate Nano Cloud GPU, starting at US$5.00 total monthly fee plus US$0.24/hr estimated usage.
- If workload is web serving, API serving, databases, analytics, VDI, VM density, app dev/test, or streaming: evaluate Premium Compute VM PRO200 to PRO600 based on RAM, vCPU and NVMe capacity needed.
- If workload needs both: run persistent services and data stores on Premium Compute VM and burst training or batch inference to Nano Cloud GPU, pausing GPU resources when execution stops.
- If storage I/O is the bottleneck: prioritize PCIe 4.0 NVMe SSD capacity and DDR5 memory sizing over adding GPUs.
