CPU Comparison
AMD Ryzen AI 7 450G vs Intel Core Ultra 5 245K
A side-by-side comparison of specs, performance and value. The AMD Ryzen AI 7 450G is an 8-core, 16-thread desktop APU based on the Zen 5 architecture, built on TSMC’s 4nm process. It integrates a Radeon 860M iGPU with 8 RDNA 3.5 compute units and an XDNA 2 NPU rated at up to 50 TOPS, targeting mainstream desktop AI PCs and Copilot+ experiences rather than pure gaming or workstation builds. With a 65W default TDP and AM5 socket, it is designed primarily for OEM systems rather than DIY retail.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Eight Zen 5 cores at up to 5.1 GHz deliver strong single-threaded and multi-threaded performance for office applications, web browsing, and light creative work, comparable to other 8-core Zen 5 desktop CPUs at similar power envelopes.
14 cores with 159W power headroom handle demanding productivity workloads well, though it sits below Core Ultra 7 and 9 models in heavily threaded tasks.
Gaming
The Radeon 860M iGPU provides playable 1080p performance in esports and older titles at medium settings, but newer AAA games often require reduced settings or resolution. It is outclassed by even low-end discrete GPUs and is weaker than the previous 8700G’s Radeon 780M in raw GPU throughput.
The 5.2 GHz boost and strong IPC of Lion Cove deliver excellent gaming performance, particularly at 1080p where CPU limits are most apparent.
Virtualization
With support for ECC (on appropriate boards), 256GB DDR5, and AMD-V/AMD-Vi, the 450G is a capable host for small VMs and containers, though power users running many concurrent VMs may prefer higher-core-count Ryzen 9 or Threadripper parts.
Good for running multiple VMs with the 14-core configuration and high power budget supporting sustained multi-threaded loads.
Efficiency
At 65W, the 450G offers a good balance of performance and power draw, and the 4nm Zen 5 cores are efficient at this TDP. However, users wanting the absolute best efficiency per dollar can find cheaper alternatives that trade some performance for lower cost.
Significantly more efficient than previous-generation K-series processors like the 14600K, thanks to the 3 nm process, though 159W PL2 is still substantial.
Specialized Performance
AI / ML
- Up to 50 TOPS from the XDNA 2 NPU, meeting Microsoft’s Copilot+ desktop requirements for local AI experiences.
- Well suited to on-device LLMs, AI-assisted coding tools, and background AI features in Windows and applications.
- NPU is significantly more capable than the 16 TOPS units in previous Ryzen 8000G desktop APUs, shifting the balance toward AI rather than pure iGPU performance.
- Highest total AI performance in Ultra 5 at 30 TOPS
- NPU 3 handles 13 TOPS of sustained AI workloads
- 64EU iGPU contributes 8 TOPS for GPU-accelerated AI tasks
- CPU P-cores and E-cores add 9 TOPS for AI inference
- Suitable for local LLM inference, image generation, and AI-assisted editing
Content Creation
Gaming
- Radeon 860M with 8 RDNA 3.5 CUs is a step down in raw compute vs the older Radeon 780M (12 CUs) found in Ryzen 7 8700G, so integrated gaming performance is not a clear upgrade.
- Suitable for 1080p low/medium in esports and older titles; newer AAA games may need 900p/720p or low settings.
- Modern feature set including AV1 decode/encode and DisplayPort 2.1 is a plus for media and connectivity.
- 5.2 GHz boost provides leading single-threaded performance in the Ultra 5 family
- 64EU iGPU can handle light gaming at 720p/1080p low settings if needed
- Strong 1% low frame rates thanks to high P-core clocks
- Optimal pairing with mid-to-high-end GPUs like RTX 4070 or above
- Overclocking can further improve minimum frame rates

Target Audience
Strengths & Weaknesses
Pros
- 8 Zen 5 CPU cores with strong single- and multi-threaded performance at 65W.
- 50 TOPS XDNA 2 NPU for local AI and Copilot+ experiences.
- Radeon 860M iGPU with modern RDNA 3.5 feature set and AV1 support.
- AM5 platform with DDR5, PCIe 4.0, and potential ECC support.
- Unlocked multiplier and full overclocking support via EXPO, PBO and Curve Optimizer.
Cons
- iGPU has fewer CUs than the previous Ryzen 7 8700G, so integrated gaming performance is not a clear upgrade.
- Only 12 usable PCIe 4.0 lanes from the CPU, limiting multi-GPU and heavy NVMe configs.
- OEM-only availability; not sold as a boxed retail CPU for DIY builders.
- Lower base clock than Ryzen 7 8700G, which may lightly hurt lightly-threaded workloads depending on boost behavior.
- New platform still early in its lifecycle; long-term BIOS/maturity may vary by vendor.
Pros
- Unlocked multiplier for enthusiast overclocking
- Highest 5.2 GHz boost in the Ultra 5 family
- 64EU iGPU enables light gaming and GPU compute without dGPU
- ECC memory support unique in the Ultra 5 tier
- 30 TOPS total AI performance
- B0 stepping from launch indicates mature silicon
- Significant efficiency improvement over previous-gen K-series
Cons
- Most expensive Ultra 5 at $319
- No Hyper-Threading reduces multi-threaded density
- 159W PL2 requires adequate cooling investment
- 14 cores may feel limited against 20-core Ultra 7 models for heavy workloads
- No included cooler requires separate purchase
- Arrow Lake gaming performance is competitive rather than dominant
