AMD Radeon 860M vs NVIDIA RTX PRO 4500 Blackwell Comparison

The Verdict

The benchmark data presents a stark contrast between two very different GPU classes. The NVIDIA RTX PRO 4500 Blackwell is a dedicated, high-power workstation card, while the AMD Radeon 860M is a power-sipping integrated processor. The database shows the NVIDIA card with an average benchmark score of 31,532, placing it in the 76th percentile of all GPUs. The AMD Radeon 860M scores an average of 26,401, good for the 72nd percentile. This 19% overall gap is significant, but the real story emerges in the specific head-to-head test.

The only shared benchmark, Geekbench Vulkan, reveals the true scale of the performance divide. The NVIDIA RTX PRO 4500 Blackwell delivers a score of 221,768, which is 638.2% higher than the Radeon 860M's 30,043. This is not a close contest; it is a dominant victory for the dedicated card. The data suggests the RTX PRO 4500 is for professionals running demanding workstation workloads, while the Radeon 860M is for portable devices where its 15 W power envelope is the primary feature.

Where Each One Wins

The NVIDIA RTX PRO 4500 Blackwell wins in every scenario where raw compute and graphics throughput are paramount. Its Passmark G3D score of 33,360 and GPU compute score of 19,255 dwarf anything the integrated AMD part can offer. The RTX PRO 4500 also holds a Passmark G2D score of 1,336, indicating strong 2D performance. With 32 GB of GDDR7 memory on a 256-bit bus, it delivers 896.0 GB/s of bandwidth, a figure that is essential for large datasets, high-resolution textures, and complex rendering tasks. Its 50.53 TFLOPS of FP32 and FP16 performance, combined with 82 RT cores and 328 tensor cores, makes it a tool for AI inference, ray-traced visualization, and compute-heavy simulation.

The AMD Radeon 860M wins in the category of efficiency and integration. Its 15 W TDP is a fraction of the NVIDIA card's 200 W, making it suitable for thin-and-light laptops. The Radeon 860M shares system memory, which means its bandwidth is "System Dependent," a flexible but lower-performance approach. It still offers modern API support, including DirectX 12 Ultimate and Vulkan 1.4, and its 3.072 TFLOPS of FP32 performance is respectable for an integrated solution. The Radeon 860M is for users who need a capable iGPU for light gaming and media tasks without a dedicated graphics card.

Architecture Differences

The two GPUs come from different architectural lineages. The NVIDIA RTX PRO 4500 Blackwell uses the GB203 chip, built on a 5 nm process at TSMC. This chip packs 45,600 million transistors onto a 378 mm² die, achieving a transistor density of 120.6 million per mm². It is part of the Blackwell PRO W generation. The architecture is Blackwell 2.0, featuring 10,496 shading units, 328 texture mapping units, and 112 raster output units. It includes 82 RT cores and 328 tensor cores, the latter being essential for AI workloads. The memory subsystem is dedicated GDDR7, with a 256-bit bus and 896.0 GB/s bandwidth. The card connects via PCIe 5.0 x16 and draws power from a single 16-pin connector. Its base clock is 1635 MHz, boosting to 2407 MHz, with memory running at 1750 MHz or 28 Gbps effective.

The AMD Radeon 860M uses the Krackan Point chip, built on a more advanced 4 nm process at TSMC. The die size and transistor count are unknown, but the architecture is RDNA 3.5, part of the Navi III IGP generation for Strix Point Mobile. This is an integrated graphics processor, meaning it shares the system's memory rather than having its own dedicated VRAM. It has 512 shading units, 32 TMUs, and 16 ROPs. The RT core count is 8, and there are no tensor cores listed. The base clock is just 600 MHz, but the boost reaches 3000 MHz. Its FP32 performance is 3.072 TFLOPS, and its pixel rate is 48.00 GPixel/s, with a texture rate of 96.00 GTexel/s. It uses a PCIe 4.0 x8 interface and requires no power connector. The Radeon 860M's predecessor is the Navi II IGP, while the RTX PRO 4500's predecessor is Workstation Ada.

The process node difference is notable: the AMD part uses 4 nm versus NVIDIA's 5 nm. However, the NVIDIA chip compensates with a much larger die and dedicated memory. The Radeon 860M's 8 RT cores provide ray tracing capability, but the NVIDIA card's 82 RT cores are on a different scale. Similarly, the 328 tensor cores in the RTX PRO 4500 are absent in the AMD part, meaning the Radeon 860M lacks dedicated AI acceleration hardware.

Head-to-Head Benchmarks

The head-to-head comparison in the database is limited to a single test, but it is decisive. In Geekbench Vulkan, the NVIDIA RTX PRO 4500 Blackwell achieves a score of 221,768. The AMD Radeon 860M scores 30,043. The difference is 638.2% in favor of the NVIDIA card. This is the only benchmark where both products have recorded scores, and it highlights the enormous gulf in raw graphics and compute capability.

To contextualize this result, consider the nearest rivals for each GPU. The NVIDIA RTX PRO 4500 Blackwell's average score of 31,532 places it within 1% of the NVIDIA TITAN RTX (31,676, a 0.5% gap), the NVIDIA GRID M60-1Q (31,220, a 1% gap), and the NVIDIA Quadro M5000 (31,206, a 1% gap). It also sits 1.1% above the Intel Arc Pro A30M (31,894). This means the RTX PRO 4500 is essentially in the same performance tier as these older or lower-tier dedicated cards, despite being a modern Blackwell part.

The AMD Radeon 860M's average score of 26,401 is nearly identical to its nearest rivals. The NVIDIA GeForce MX550 scores 26,421 (a 0.1% gap), the NVIDIA GeForce RTX 5060 scores 26,331 (a 0.3% gap), the AMD Radeon RX 5700 XT 50th Anniversary scores 26,553 (a 0.6% gap), and the NVIDIA RTX A4000 scores 26,683 (a 1.1% gap). This shows that the Radeon 860M, despite being an integrated GPU, performs in the same range as several dedicated mobile and entry-level desktop cards. The data indicates that the Radeon 860M is a competent integrated solution, but it is not in the same league as the RTX PRO 4500.

Looking at the broader benchmark suite for the NVIDIA card, its Passmark scores show a mixed profile. The Passmark G3D score of 33,360 and GPU compute score of 19,255 are strong, but the DirectX 10 score of 204, DirectX 11 score of 320, DirectX 12 score of 119, and DirectX 9 score of 397 are comparatively low. This suggests that the card's performance is highly workload-dependent, with newer APIs and compute tasks benefiting most from its architecture. The 3DMark Steel Nomad DX12 score of 7,025 reinforces its strength in modern DirectX 12 titles.

The AMD Radeon 860M only has two recorded benchmarks: Geekbench OpenCL at 22,759 and Geekbench Vulkan at 30,043. The Vulkan score is notably higher than the OpenCL score, indicating that the RDNA 3.5 architecture is well-optimized for Vulkan workloads. However, without additional test data, it is difficult to assess its performance across a wider range of applications. The available data shows a capable integrated GPU, but one that is fundamentally limited by its 512 shading units and shared memory architecture.

In terms of raw throughput, the NVIDIA card's pixel rate of 269.6 GPixel/s and texture rate of 789.5 GTexel/s are multiples of the AMD part's 48.00 GPixel/s and 96.00 GTexel/s. The FP32 compute difference is similarly large: 50.53 TFLOPS versus 3.072 TFLOPS. These figures explain why the NVIDIA card dominates in the shared Vulkan benchmark and why it is positioned for professional workstations, while the Radeon 860M is suited for portable devices where its 15 W power draw is a critical advantage.
