Analysis: Intel Arc B580 vs NVIDIA RTX PRO 4500 Blackwell Server
Where Each One Wins
The Intel Arc B580 and NVIDIA RTX PRO 4500 Blackwell Server occupy entirely different segments of the GPU market, and the benchmark data reflects that split clearly. The Arc B580 has a complete set of recorded benchmark scores across 3DMark, Geekbench, and Passmark tests, with an average benchmark score of 23021. The RTX PRO 4500, by contrast, has no recorded benchmark scores in the database, so its wins cannot be quantified through direct measurement.
The Arc B580's recorded data shows its strongest results in specific workloads. Its Geekbench Vulkan score of 109672 stands well above its OpenCL score of 92821, indicating the architecture favors Vulkan compute and graphics paths. In Passmark tests, the DirectX 9 score of 183 is the highest among the DirectX legacy tests, while DirectX 10 and DirectX 12 both record 76, and DirectX 11 records 128. The Passmark G3D score of 15748 versus the GPU compute score of 7729 shows the card delivers roughly double the graphics performance relative to its compute throughput in those tests.
The RTX PRO 4500's lack of benchmark entries means the database records zero wins for either side in head-to-head comparisons. The card's positioning as a server product with no display outputs suggests its workload profile targets compute, AI, and rendering tasks that are not captured in the consumer-oriented benchmark suite used for the Arc B580. The data shows the Arc B580 is the only one of the two with measurable client-side graphics performance.
Architecture Differences
The two GPUs share a 5 nm process node and TSMC as the foundry, but the architectural divergence is substantial. The Intel Arc B580 uses the BMG-G21 chip with Xe2-HPG architecture, part of the Battlemage generation under the Arc 5 family. It packs 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1M per mm². The NVIDIA RTX PRO 4500 uses the GB203 chip with Blackwell 2.0 architecture from the Server Blackwell generation, containing 45,600 million transistors on a 378 mm² die for a density of 120.6M per mm². The NVIDIA chip has more than double the transistors on a die that is only about 39% larger.
Memory configurations differ fundamentally. The Arc B580 uses 12 GB of GDDR6 on a 192-bit bus with 456.0 GB/s bandwidth and 19 Gbps effective memory speed. The RTX PRO 4500 uses 32 GB of GDDR7 on a 256-bit bus with 800.3 GB/s bandwidth and 25 Gbps effective speed. The RTX PRO 4500 has nearly double the memory capacity and about 75% more bandwidth.
Compute resources scale with the transistor budget. The RTX PRO 4500 has 10496 shading units, 328 TMUs, 112 ROPs, 82 ray tracing cores, and 328 tensor cores. The Arc B580 has 2560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores, with no tensor core count listed. The RTX PRO 4500's FP32 throughput of 50.70 TFLOPS is about 3.7 times the Arc B580's 13.67 TFLOPS. Notably, the RTX PRO 4500 runs FP16 at the same 50.70 TFLOPS with a 1:1 ratio, while the Arc B580 reaches 27.34 TFLOPS FP16 via a 2:1 ratio.
Clock behavior differs sharply. The Arc B580 runs a flat 2670 MHz for both base and boost clocks, while the RTX PRO 4500 has a 1215 MHz base clock that boosts to 2415 MHz. The Arc B580's higher sustained clock partially compensates for its smaller compute array. The RTX PRO 4500 draws 165 W TDP compared to the Arc B580's 190 W, despite delivering far more compute throughput.
Head-to-Head Benchmarks
Direct head-to-head benchmark data is absent from the database for these two products. The RTX PRO 4500 has no recorded scores, so no direct comparison of individual test results is possible. However, the Arc B580's nearest rival data provides context for its performance tier. Its average benchmark score of 23021 places it within 0.2% of the AMD Radeon RX 580 2048SP (23061), 0.6% ahead of the NVIDIA GeForce RTX 2080 (22895), 0.7% behind the NVIDIA GeForce RTX 3080 (23172), and 1% behind the NVIDIA P106-100 (23249). These deltas are all within roughly one percentage point, indicating the Arc B580 sits in a tightly packed performance band around those cards.
The Arc B580's 3DMark Steel Nomad DX12 score of 3068 provides a modern DirectX 12 workload reference point. Its Geekbench OpenCL score of 92821 and Vulkan score of 109672 show Vulkan delivering about 18% higher throughput in that benchmark suite. The Passmark G2D score of 709 reflects 2D graphics capability, while the G3D score of 15748 and GPU compute score of 7729 complete the picture.
The RTX PRO 4500's nearest rival list is empty, and its average benchmark score is recorded as 0, which reflects the absence of data rather than a literal zero-performance result. The database records its percentile versus all GPUs at 50, which is the default midpoint for an unmeasured product, not a meaningful performance ranking. Its specifications indicate a far higher compute ceiling than the Arc B580 based on shading units, memory bandwidth, and FP32 throughput, but those advantages cannot be confirmed through recorded benchmark deltas.
