Analysis: AMD Radeon 860M vs NVIDIA RTX PRO 4500 Blackwell Server
Where Each One Wins
The AMD Radeon 860M and NVIDIA RTX PRO 4500 Blackwell Server occupy completely different positions in the database. The Radeon 860M is an integrated graphics processor for mobile devices, while the RTX PRO 4500 is a dedicated server-class accelerator. Their benchmark presence reflects this split: the 860M has recorded scores in two OpenCL and Vulkan tests, while the RTX PRO 4500 has no benchmark entries in the database at all. This means the comparison is primarily architectural and specification-based rather than performance-driven.
The Radeon 860M delivers measurable results in consumer-oriented workloads. Its Geekbench OpenCL score of 22,759 and Vulkan score of 30,043 place it at the 72nd percentile among all GPUs in the database. The average benchmark score of 26,401 puts it within 1.1% of the NVIDIA RTX A4000 and 0.6% behind the AMD Radeon RX 5700 XT 50th Anniversary. The 860M effectively trades blows with dedicated laptop and desktop GPUs from previous generations, which is notable for an integrated part.
The RTX PRO 4500 has no recorded benchmark scores, so its wins cannot be quantified through head-to-head measurements. Its strengths are structural: 10,496 shading units, 82 ray tracing cores, 328 tensor cores, and 32 GB of GDDR7 memory on a 256-bit bus with 800.3 GB/s bandwidth. These are server-class specifications aimed at compute-heavy workloads rather than rasterization or gaming. The data shows the RTX PRO 4500 wins on raw resources, while the 860M wins on having any measured performance at all in the database.
Architecture Differences
The two GPUs come from different manufacturers and process nodes. The AMD Radeon 860M uses the Krackan Point chip built on RDNA 3.5 architecture at TSMC's 4 nm process. It belongs to the Navi III IGP generation for Strix Point mobile platforms. The NVIDIA RTX PRO 4500 uses the GB203 chip on Blackwell 2.0 architecture at TSMC's 5 nm process, part of the Server Blackwell generation. The process node difference matters: 4 nm allows denser transistor packing, though the database records the RTX PRO 4500's transistor count at 45,600 million with a die size of 378 mm², giving a density of 120.6 million transistors per mm². The 860M's transistor count and die size are listed as unknown, so no direct density comparison is possible.
Memory architecture separates them sharply. The 860M uses system-shared memory, meaning its bandwidth is system-dependent and its bus width is system-shared. The RTX PRO 4500 has dedicated 32 GB of GDDR7 memory on a 256-bit bus, delivering 800.3 GB/s of bandwidth. Clock speeds also differ: the 860M runs at 600 MHz base and 3000 MHz boost, while the RTX PRO 4500 runs at 1215 MHz base and 2415 MHz boost. The 860M's boost clock is higher, but the RTX PRO 4500's massive shading unit count compensates for the lower boost.
Compute resources are an order of magnitude apart. The RTX PRO 4500 has 10,496 shading units, 328 texture mapping units, 112 raster output units, 82 ray tracing cores, and 328 tensor cores. The 860M has 512 shading units, 32 TMUs, 16 ROPs, and 8 ray tracing cores, with no tensor cores listed. Pixel rate favors the RTX PRO 4500 at 270.5 GPixel/s versus 48.00 GPixel/s for the 860M. Texture rate is 792.1 GTexel/s versus 96.00 GTexel/s. FP32 compute is 50.70 TFLOPS versus 3.072 TFLOPS, and both run FP16 at a 1:1 ratio.
Power and physical design differ entirely. The 860M is an IGP with 15 W TDP, no power connectors, and no slot width beyond its integrated nature. The RTX PRO 4500 is a single-slot card drawing 165 W, requiring one 16-pin power connector and a suggested 450 W power supply. It measures 267 mm in length, 111 mm in height, and 40 mm in width. The bus interfaces differ: PCIe 4.0 x8 for the 860M versus PCIe 5.0 x16 for the RTX PRO 4500. Display outputs are portable-device dependent for the 860M, while the RTX PRO 4500 has no outputs at all.
The Verdict
The data indicates these are not competing products. The Radeon 860M is an integrated mobile GPU with measured consumer benchmarks at the 72nd percentile. Its OpenCL score of 22,759 and Vulkan score of 30,043 show it can handle mainstream graphics tasks. The RTX PRO 4500 is a server accelerator with no display outputs, no benchmark scores, and specifications aimed at compute-heavy datacenter workloads. Its 82 ray tracing cores and 328 tensor cores, combined with 32 GB of GDDR7 memory and 800.3 GB/s bandwidth, position it for AI inference, rendering, and scientific compute.
From the recorded data, the 860M is the only one with measurable graphics performance. The RTX PRO 4500's absence from benchmark results means the database cannot confirm any performance advantage, despite its superior specifications. Users needing an integrated graphics solution for a portable device would choose the 860M. Users needing a server-side accelerator with dedicated memory and massive compute resources would choose the RTX PRO 4500, but the database currently lacks evidence of its real-world performance.

Head-to-Head Benchmarks
The database contains no head-to-head benchmark results between these two GPUs. The winsA and winsB counts are both zero, and the headToHeadBenchmarks list is empty. This absence is itself informative: the two products target such different segments that no direct benchmark comparison has been recorded.
The Radeon 860M's standalone benchmarks provide context for its position. Its OpenCL score of 22,759 and Vulkan score of 30,043 produce an average of 26,401. The nearest rival, the NVIDIA GeForce MX550, averages 26,421, a delta of -0.1%. The NVIDIA GeForce RTX 5060 averages 26,331, a delta of 0.3%. The AMD Radeon RX 5700 XT 50th Anniversary averages 26,553, a delta of -0.6%. The NVIDIA RTX A4000 averages 26,683, a delta of -1.1%. These narrow deltas indicate the 860M sits in a tight performance cluster despite being an integrated GPU.
The RTX PRO 4500 has no benchmark scores, so its percentile is 50 and its average score is zero. Without data, the database cannot place it relative to any GPU. Its specifications suggest enormous compute headroom, but the absence of measurements means those specifications remain theoretical in the database's context.
