Quick buying answer
Choose Ryzen AI Max+ PRO 495 for a 192GB x86 Windows/Linux local-AI workstation with broader hardware choice. Choose Mac Studio M5 Ultra when macOS, MLX, much higher configurable unified memory or Apple's media workflow is the better fit.
Windows or Linux AI development and buyers whose local-AI workload needs substantially more memory than a typical discrete GPU.
Choose a lower-memory Ryzen AI Max system, RTX Spark, Mac Studio or conventional RTX workstation when its software stack, performance profile or price fits your workload better.
Confirm the exact processor, installed memory, SSD, operating system, network ports and the AI runtime you plan to use before ordering.
What matters for a UK buyer
The 2026 Mac Studio M5 Ultra changes this comparison because it can be configured with substantially more unified memory than a Ryzen AI Max+ PRO 495 system and offers 1.2TB/s memory bandwidth. The Ryzen platform counters with x86 compatibility, Windows or Linux choices and a growing range of 192GB systems from several vendors.
For local AI, operating system and backend support should drive the decision before synthetic performance. MLX and Apple-optimised workflows can strongly favour Mac Studio, while x86 applications, Windows tooling and AMD-supported Linux stacks can favour the Ryzen platform.

Detailed buying guide
Who should consider a Ryzen AI Max+ PRO 495 system?
This platform is aimed at buyers who need substantially more local memory than a conventional consumer GPU provides, while keeping an x86 Windows or Linux workstation workflow.
The strongest reason to buy it is memory capacity for local AI, development, data work and professional applications. If your workload fits comfortably on a smaller GPU or a 64GB to 128GB system, compare the total platform cost before paying for 192GB.
How should I think about the 192GB unified-memory design?
The CPU and Radeon 8065S share the same LPDDR5X memory pool instead of using separate system RAM and discrete GPU VRAM. That can make very large local models possible without buying multiple discrete GPUs.
Do not treat 192GB as 192GB of guaranteed model space. Supported systems can allocate up to 160GB as graphics memory, and the operating system, runtime, context cache and other processes still need headroom.
What does the Radeon 8065S change?
The Radeon 8065S is the integrated RDNA 3.5 GPU in the Ryzen AI Max+ PRO 495, with 40 compute units. For AI, the practical question is whether your chosen runtime and model are well supported on the AMD software stack you plan to use.
Check ROCm, Vulkan, DirectML or application-specific support before assuming that a model tuned for CUDA will behave identically on this platform.
How does memory differ between the 495 and M5 Ultra?
Ryzen AI Max+ PRO 495 systems support up to 192GB of LPDDR5X unified memory, with supported configurations able to allocate up to 160GB as graphics memory. The 2026 M5 Ultra Mac Studio can be configured with 256GB or 512GB unified memory.
The numbers are not directly interchangeable because the operating systems, runtimes, memory management and accelerators are different. Compare the actual model and software you plan to run.
What storage and networking should I prioritise?
Large local models can consume hundreds of gigabytes across several quantisations, so a 2TB SSD fills quickly. Multiple M.2 slots or larger SSD options are useful if you keep several models, datasets and project files locally.
Fast Ethernet matters when models or datasets live on a NAS or when several workstations share storage. The current 495 systems vary from 2.5GbE to 10GbE, so check the exact machine rather than assuming the processor defines the network ports.
How do I avoid buying the wrong configuration?
Check the exact processor name, installed memory, SSD size, operating system and product model. A Ryzen AI Max+ 395 system with 128GB is not the same configuration as a Ryzen AI Max+ PRO 495 system with 192GB.
Amazon titles can combine family names and supported capacities. This page only treats installed capacity as confirmed when the listing actually identifies that configuration.
When is the premium worth paying?
The premium makes sense when 192GB removes a real workload limit, such as a model that will not fit within 96GB or 128GB, or when the system's networking, storage and management features replace additional hardware.
If the workload is mainly conventional gaming, light creation or models that already fit comfortably on a lower-cost system, compare RTX, Ryzen AI Max+ 395 and Mac options before buying.
How to read this comparison
Products are grouped by the model, platform and configuration shown in the listing. If an important specification is unclear, it is marked as not confirmed rather than guessed. Accessories and incomplete systems are left out of the main results.
Prices and availability can change quickly. Use the last-checked time as a freshness guide, then confirm the current price, seller, delivery date and exact configuration on Amazon before ordering.
This page covers Amazon offers rather than every UK retailer. Compare the complete configuration and total delivered cost, not just the headline price.
Frequently asked questions
Does this page compare every UK retailer?
No. Live prices on this page come from Amazon. Other UK retailers may have different stock, delivery times or prices, so compare the full configuration before ordering.
Why can the Amazon price change after I click?
Prices and availability can change between checks. Use the last-checked time on each card as a freshness guide, then confirm the current price, seller, delivery date and configuration on Amazon.
Does 192GB mean all of it is available to the GPU?
No. The Ryzen AI Max+ PRO 495 supports up to 192GB of unified system memory, while supported configurations can allocate up to 160GB as graphics memory. The operating system, applications and AI runtime also need memory.
Can a 192GB system run every large language model?
No. Model size is only one constraint. Quantisation, context length, runtime overhead, backend support and model architecture all affect whether a model fits and how quickly it runs.
Could an accessory appear instead of a complete system?
The main results are intended for complete systems. Still check the product title, installed memory, SSD, operating system and included items before ordering.
What happens when a specification is unclear?
Unclear specifications are left as not confirmed rather than copied from a similar model. Check the exact Amazon listing when a memory, storage, network or operating-system detail matters to your purchase.
