The practical choice comes down to compatibility, required libraries and tools, porting effort, and performance on your own workload. AMD’s release added new GPU and framework support, but its published cross-vendor speed comparison is one vendor-reported test, not proof that ROCm is generally faster.
What ROCm 7.0 is—and what it changes
ROCm is AMD’s software stack for GPU computing. ROCm 7.0.0 is a specific release dated September 16, 2025; AMD’s release notes say they apply to Linux. Among the release’s changes are support for AMD Instinct MI355X and MI350X GPUs and updated framework support for PyTorch 2.7, JAX 0.6.0, TensorFlow 2.19.1, ONNX Runtime 1.22.0, and Triton 3.3.0. The notes also identify vLLM support for OCP FP8 and FP4 precision for Llama 3.1 405B. These are version-specific support statements, not a guarantee that every combination of framework, model, and GPU works. AMD ROCm 7.0.0 release notes.
ROCm 7.0 also changes how AMD packages its GPU driver and ROCm software stack: the amdgpu driver is separated from the ROCm stack. For teams maintaining existing HIP applications, the release notes warn that HIP API changes may be incompatible with prior ROCm versions and that some applications may need recompilation.
Does ROCm 7 support your GPU and operating system?
Check the exact GPU and Linux distribution in AMD’s ROCm 7.0.1 compatibility matrix, which documents 7.0.x support. Compatibility is not a blanket promise for all Radeon cards or Linux distributions. For example, AMD lists the Radeon RX 9070 XT, but its supported OS list is limited to Ubuntu 24.04.3, Ubuntu 22.04.5, and RHEL 9.6. Other GPUs have different lists.

For ROCm 7.0.0, AMD’s release notes say Ubuntu 24.04.3 and Rocky Linux 9 support were added, while Ubuntu 24.04.2 and SLES 15 SP6 support ended for that release. The notes also add KVM passthrough for MI350X and MI355X, and VMware ESXi 8 support for MI300X. These platform and virtualization details matter when planning a deployment; confirm the matrix for the specific GPU and ROCm point release you intend to use.
If you are considering a Radeon RX 9070 XT for local AI or GPU development, its ROCm 7.0.x support is limited to the distributions listed above. Verify the current compatibility matrix against your intended OS and software before buying.

ROCm vs. CUDA: compare the workflow, not just the names
CUDA is NVIDIA’s parallel-computing platform and programming model, backed by a toolkit. NVIDIA’s documentation describes the toolkit as including compiler and runtime components, libraries, profiling and debugging tools, guides, API references, and release notes. That makes CUDA more than a single API to compare against HIP. NVIDIA defines CUDA as a platform and programming model that uses the GPU to increase computing performance; that is NVIDIA’s description, not an independent performance measurement. See the CUDA Programming Guide and CUDA 12.8 release notes.

For a real decision, inventory the exact application, framework and version, libraries, debugging and profiling tools, GPU, and OS you need. Compare those requirements against the vendors’ current documentation and test the complete workload. Matching API names alone does not establish that the same code, dependencies, or performance will carry over.

Can ROCm replace CUDA for your workload?
Possibly, if the workload runs on a supported AMD GPU and OS, its frameworks and dependencies are supported for the ROCm release you plan to use, and you can absorb any required porting and validation. ROCm 7.0’s named framework support is useful evidence for those specific versions, but it does not establish compatibility for every model, library, custom kernel, or application.
- A plausible fit: you are starting a project or can adapt it, your GPU and OS appear in AMD’s compatibility matrix, and the framework versions you need are named in the ROCm support documentation.
- A higher-risk switch: your production application depends on CUDA-specific libraries, custom kernels, or a fixed toolchain, or you cannot change the hardware or OS to match AMD’s supported combinations.
- Before committing: validate installation, model loading, correctness, memory use, performance, and debugging on the intended system. A successful framework install alone does not prove that a full application is ready to migrate.
AMD says ROCm 7.0 includes vLLM support for OCP FP8 and FP4 precision for Llama 3.1 405B, but that specific release-note item should not be read as a universal guarantee for other model sizes, precision modes, hardware, or configurations.

How hard is it to port CUDA code to ROCm?
There is no single conversion effort that applies to every application. AMD describes HIPIFY as a way to port CUDA code to HIP C++, and says HIP 7.0 was designed to align HIP C++ more closely with CUDA and reduce cross-vendor development friction. AMD also acknowledges that implementation differences have often required manual intervention. HIPIFY and closer API alignment can help, but neither establishes drop-in compatibility for every CUDA application. AMD’s HIP 7.0 portability discussion.
AMD describes the goal this way: “To improve code portability between AMD ROCm and other programming models, HIP API has been updated in ROCm 7.0.0 to simplify cross-platform programming.” The same release notes warn that some existing HIP applications may need recompilation, so teams maintaining HIP code should treat a ROCm 7.0 upgrade as a compatibility and build change—not assume that previously compiled applications will continue unchanged.

In practice, the effort depends on how much of the application is CUDA-specific and how much relies on portable framework code. Plan to inspect conversion output, address implementation differences, rebuild, and validate results on the target hardware. The cited AMD guidance supports the possibility of manual work; it does not provide a universal conversion time or guarantee for a particular codebase.
What do AMD’s ROCm 7.0 benchmarks actually show?
AMD Performance Labs reports that a pre-release MI355X platform with eight GPUs achieved up to 1.3× the inference throughput of an eight-GPU NVIDIA B200 platform for DeepSeek R1 using SGLang. AMD says it conducted the test on May 25, 2025. The comparison used different CPUs, GPU memory configurations, drivers, containers, and software builds; AMD identifies its side as pre-release build 16047 and the NVIDIA side as CUDA 12.8. This is a vendor-reported result for one disclosed configuration, not a general finding that ROCm is faster than CUDA. AMD’s benchmark details.
AMD also reports up to 4.6× inference-throughput uplift for a ROCm 7.0 preview configuration versus ROCm 6.x on MI300X, averaging across three named models. The compared vLLM versions differ, so this is AMD’s software-stack comparison, not a direct CUDA comparison. Separately, AMD reports approximately 3× training throughput in its MI355X-versus-MI300X generational comparison; that comparison combines hardware and software changes and does not isolate the effect of ROCm alone. Both claims are from AMD’s 2025 ROCm 7.0 blog. AMD ROCm 7.0 performance blog.
These figures can help identify workloads AMD chose to demonstrate, but they do not settle which platform is faster for your model, batch size, precision, software stack, or deployment. The cited material does not provide an independent cross-vendor benchmark that establishes a broad ROCm-versus-CUDA winner.

How to make the platform decision
- Verify hardware and OS: match your exact GPU and distribution to AMD’s ROCm 7.0.x matrix, or verify the NVIDIA GPU and driver requirements for the CUDA release you plan to use.
- Verify the software stack: check the exact framework versions, libraries, model support, and developer tools your application requires—not just whether it uses PyTorch or another framework in general.
- Estimate migration work: identify CUDA-specific code and dependencies, then assess whether HIPIFY and HIP C++ can cover them or whether manual changes are needed.
- Test the complete workload: build and run the application on the target machine, validate correctness, and measure the performance that matters to your use case.
- Account for upgrade cost: if you already maintain HIP applications, plan for compatibility review and possible recompilation when moving to ROCm 7.0.
