AMD Radeon 820M vs NVIDIA RTX PRO 4500 Blackwell Comparison

The AMD Radeon 820M and the NVIDIA RTX PRO 4500 Blackwell occupy completely different segments of the graphics hardware spectrum. The recorded data shows an integrated processor from the RDNA 3.5 architecture facing a professional workstation discrete card built on Blackwell 2.0. Their benchmark scores, physical specifications, and intended operational envelopes share almost no common ground, which makes the comparison straightforward but stark. The Radeon 820M carries a percentile rank of 50 against all GPUs in the database, while the RTX PRO 4500 sits at the 76th percentile, a gap that the raw numbers in the database confirm across every measurable category.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark runs between these two units, so the analysis relies on the available benchmark suite for the NVIDIA RTX PRO 4500 Blackwell. The AMD Radeon 820M has no recorded benchmark scores in the database, meaning its performance can only be assessed through its architectural attributes and percentile placement. The RTX PRO 4500 delivers a 3DMark Steel Nomad DX12 score of 7025, a result that indicates substantial modern DirectX 12 workload capacity. Its Geekbench Vulkan score reaches 221768, showing strong cross-platform graphics API performance in the database records.

The PassMark suite provides the most complete picture for the NVIDIA card. The PassMark G3D score stands at 33360, while the GPU compute score reaches 19255. These numbers place the RTX PRO 4500 in a performance tier that the Radeon 820M, with its 128 shading units, does not approach. The PassMark DirectX 9 score of 397, DirectX 10 score of 204, DirectX 11 score of 320, and DirectX 12 score of 119 reveal how the card distributes its capabilities across legacy and modern API workloads. The DirectX 12 score being lower than the DirectX 9 score suggests that the recorded measurements capture different workload characteristics, with the 3DMark Steel Nomad result of 7025 providing a more contemporary gauge of DX12 performance.

The FP32 compute figures in the database illustrate the scale of the divide. The RTX PRO 4500 delivers 50.53 TFLOPS of FP32 throughput, while the Radeon 820M manages 716.8 GFLOPS. That is a difference of roughly 70 times in raw floating-point capacity. The texture rate tells a similar story: 789.5 GTexel/s for the NVIDIA card against 22.40 GTexel/s for the AMD part. Pixel rate also favors the professional card at 269.6 GPixel/s versus 11.20 GPixel/s for the integrated solution. Every throughput metric in the database points the same direction, and the magnitude of the differences indicates that these products are not competing for the same workloads.

Where Each One Wins

The RTX PRO 4500 Blackwell wins on every recorded performance benchmark, every compute metric, and every memory specification. Its 10496 shading units, 328 texture mapping units, and 112 ROPs provide the hardware foundation for its dominance in rendering tasks. The 82 ray tracing cores and 328 tensor cores extend its capabilities into ray-traced and AI-accelerated workloads, areas where the Radeon 820M with its 2 ray tracing cores has minimal presence. The 32 GB of GDDR7 memory on a 256-bit bus delivers 896.0 GB/s of bandwidth, which is essential for professional visualization and large dataset manipulation. The Radeon 820M uses system shared memory with bandwidth described as system dependent, meaning its memory performance varies with the host platform rather than representing a fixed capability.

The AMD Radeon 820M wins in power consumption and physical footprint. Its TDP is 15 W, compared to 200 W for the RTX PRO 4500. It requires no power connectors, while the NVIDIA card uses a single 16-pin connector and the database suggests a 550 W power supply. The AMD part is an IGP with no slot width, while the NVIDIA card occupies a dual-slot design measuring 267 mm in length. The Radeon 820M also carries a higher boost clock relative to its base: 2800 MHz boost against a 400 MHz base, while the RTX PRO 4500 boosts from 1635 MHz to 2407 MHz. These figures show that the AMD integrated part can scale its clock aggressively under load, but the absolute performance ceiling remains far below the discrete card.

The percentile placement reinforces this split. The Radeon 820M sits at the 50th percentile against all GPUs, which places it in the middle of the database distribution. The RTX PRO 4500 sits at the 76th percentile, a position that reflects its professional-grade capabilities. The nearest rivals for the RTX PRO 4500 in the database include the NVIDIA TITAN RTX with an average score of 31676 and a delta of -0.5%, the NVIDIA GRID M60-1Q at 31220 with a delta of 1%, the NVIDIA Quadro M5000 at 31206 with a delta of 1%, and the Intel Arc Pro A30M at 31894 with a delta of -1.1%. These deltas show the RTX PRO 4500 landing within a tight band around these established cards, with its average benchmark score of 31532 placing it between the TITAN RTX and the GRID M60-1Q.

The Verdict

The data indicates that the NVIDIA RTX PRO 4500 Blackwell is the choice for any workload that demands substantial compute, large memory capacity, or professional rendering features. Its 50.53 TFLOPS FP32, 896.0 GB/s memory bandwidth, and 82 ray tracing cores position it as a serious workstation tool. The AMD Radeon 820M, with its 15 W TDP and system shared memory, serves a fundamentally different purpose. It belongs in portable or low-power systems where the CPU integrates the GPU and external discrete graphics is not an option.

The Radeon 820M has no recorded benchmark scores, so the database cannot quantify its real-world performance directly. Its 50th percentile rank suggests it lands in the middle of all GPUs tracked, which is a reasonable position for an integrated solution. The RTX PRO 4500, by contrast, has a full benchmark suite and an average score of 31532, putting it in the upper quartile of the database. The verdict from the recorded data is unambiguous: the RTX PRO 4500 is the performance leader by every measured metric, while the Radeon 820M is the efficiency leader with its minimal power draw and integrated form factor. Neither product can substitute for the other, and the choice depends entirely on whether the system needs a low-power integrated GPU or a high-throughput professional card.
