Intel Arc A580 vs NVIDIA RTX PRO 4500 Blackwell Workstation Comparison

Intel Arc A580 vs NVIDIA RTX PRO 4500 Blackwell Workstation

The Intel Arc A580 and NVIDIA RTX PRO 4500 Blackwell Workstation occupy different positions in the database, with the Arc A580 showing an average benchmark score of 57,756 and sitting at the 87th percentile among all GPUs, while the RTX PRO 4500 currently has no recorded benchmark scores and stands at the 50th percentile. The Arc A580's nearest rivals include the AMD Radeon RX 5600 OEM at 58,085 (0.6% ahead), the Intel Arc A570M at 58,239 (0.8% ahead), and the AMD Radeon RX 6950 XT at 58,392 (1.1% ahead), while the AMD Radeon RX 9070 GRE trails at 57,367 (0.7% behind). The NVIDIA card's absence of recorded measurements means the comparison relies on architectural specifications and theoretical throughput figures rather than direct head-to-head results.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two cards, so the available performance indicators come from each card's recorded tests. The Intel Arc A580 has three benchmark entries: a 3DMark Steel Nomad DX12 score of 2,229, a Geekbench OpenCL score of 91,657, and a Geekbench Vulkan score of 79,381. The NVIDIA RTX PRO 4500 Blackwell Workstation has zero recorded benchmark scores, leaving its actual application performance unmeasured in the database.

Without direct comparisons, the theoretical compute figures provide the only quantitative bridge between the two. The RTX PRO 4500 delivers 50.53 TFLOPS of FP32 throughput, while the Arc A580 delivers 12.29 TFLOPS, a gap of roughly 4.1 times on paper. In FP16, the NVIDIA card maintains 50.53 TFLOPS at a 1:1 ratio, whereas the Intel card reaches 24.58 TFLOPS at a 2:1 ratio, meaning the NVIDIA card doubles the Intel card's peak half-precision throughput. Pixel throughput shows 269.6 GPixel/s for the NVIDIA card versus 192.0 GPixel/s for the Intel card, and texture throughput shows 789.5 GTexel/s versus 384.0 GTexel/s, indicating a 1.4x advantage in pixel fill and a 2.1x advantage in texture fill.

The percentile data reinforces the split: the Arc A580's 87th percentile reflects its recorded scores against the full GPU population, while the RTX PRO 4500's 50th percentile with an average score of zero reflects an absence of data rather than a measured performance level. The Arc A580's nearest rival deltas are all within 1.1%, placing it in a tight cluster with the RX 5600 OEM, RX 9070 GRE, Arc A570M, and RX 6950 XT, none of which approach the RTX PRO 4500's theoretical FP32 output.

Architecture Differences

The two cards use fundamentally different architectures and process technologies. The Intel Arc A580 uses the DG2-512 chip built on the Xe-HPG architecture, part of the Alchemist generation (Arc 5), fabricated on a 6 nm process at TSMC. The NVIDIA RTX PRO 4500 uses the GB203 chip built on the Blackwell 2.0 architecture, part of the Blackwell PRO W (x000) generation, fabricated on a 5 nm process at TSMC. The transistor counts diverge sharply: 21,700 million for the Intel chip versus 45,600 million for the NVIDIA chip, despite the NVIDIA die being smaller at 378 mm² compared to 406 mm². Transistor density tells the story, with the NVIDIA chip packing 120.6M transistors per mm² versus 53.4M per mm² for the Intel chip.

The shading resources differ by a wide margin. The Arc A580 contains 3,072 shading units, 192 texture mapping units, 96 raster output units, and 24 ray tracing cores, while the RTX PRO 4500 contains 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The NVIDIA card also includes tensor cores, which the Intel card lacks entirely in the recorded specifications. The Intel card's FP16 performance comes from a 2:1 ratio relative to FP32, while the NVIDIA card achieves a 1:1 ratio, indicating a different approach to half-precision execution.

Memory architecture shows both cards using a 256-bit bus, but with different memory types and capacities. The Arc A580 uses 8 GB of GDDR6 at 2000 MHz (16 Gbps effective) for 512.0 GB/s of bandwidth, while the RTX PRO 4500 uses 32 GB of GDDR7 at 1750 MHz (28 Gbps effective) for 896.0 GB/s. The NVIDIA card offers four times the capacity and 1.75 times the bandwidth. The RTX PRO 4500 also uses a PCIe 5.0 x16 interface versus the Arc A580's PCIe 4.0 x16, and its display outputs are four DisplayPort 2.1b ports, while the Intel card offers one HDMI 2.1 and three DisplayPort 2.0 ports. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The Intel Arc A580 wins in the measured benchmark category because it has recorded scores, while the NVIDIA RTX PRO 4500 has none. The Arc A580's Geekbench OpenCL score of 91,657 and Vulkan score of 79,381 place it in the 87th percentile of all GPUs, with its average benchmark score of 57,756 putting it within 1.1% of several AMD and Intel rivals. The 3DMark Steel Nomad DX12 result of 2,229 provides a DirectX 12 workload reference point that the NVIDIA card currently lacks in the database.

The NVIDIA RTX PRO 4500 wins on raw specification ceilings across every compute and memory category. Its 50.53 TFLOPS FP32 output is 4.1 times the Arc A580's 12.29 TFLOPS, and its 50.53 TFLOPS FP16 output is 2.1 times the Arc A580's 24.58 TFLOPS. The 32 GB GDDR7 memory with 896.0 GB/s bandwidth versus 8 GB GDDR6 with 512.0 GB/s creates a capacity and bandwidth advantage that matters for large datasets. The 328 tensor cores provide matrix acceleration capabilities absent from the Intel card's specification list, and the 82 RT cores versus 24 suggest a higher ray tracing workload ceiling, though no ray tracing benchmarks are recorded for either card.

Power draw favors the Intel card on paper: 175 W TDP versus 200 W for the NVIDIA card, with the Intel card suggesting a 450 W PSU and the NVIDIA card suggesting 550 W. However, the NVIDIA card achieves its higher throughput within only a 25 W higher TDP, indicating substantially better performance per watt in theoretical terms. The Arc A580 uses two 8-pin power connectors, while the RTX PRO 4500 uses a single 16-pin connector, and the NVIDIA card is physically smaller at 267 mm length, 111 mm height, and 40 mm width, while the Intel card has no recorded dimensions.

The Verdict

The data supports choosing the NVIDIA RTX PRO 4500 Blackwell Workstation for workloads that demand maximum theoretical throughput, large memory capacity, and high bandwidth. Its 50.53 TFLOPS FP32, 50.53 TFLOPS FP16, 32 GB GDDR7, 896.0 GB/s bandwidth, and 328 tensor cores place it in a different performance class than the Arc A580, and its higher transistor density on a smaller die suggests a more advanced implementation. The 82 RT cores and PCIe 5.0 interface also favor compute-heavy and data-intensive tasks.

The Intel Arc A580 is the only card of the two with recorded benchmark data, showing an 87th percentile standing and an average score of 57,756 that places it within 1.1% of several rivals. Its lower TDP of 175 W and dual 8-pin connectors may suit systems with more modest power delivery, and its 6 nm process and smaller transistor budget align with a lower-tier positioning. For users who rely on measured performance from the database, the Arc A580 has verifiable results, while the RTX PRO 4500 remains an unmeasured specification sheet.

The absence of benchmarks for the NVIDIA card means its real-world performance is unknown in the database, so any selection based on recorded measurements must favor the Intel card, while any selection based on architectural and theoretical specifications must favor the NVIDIA card. The 1:1 FP16 ratio, 120.6M per mm² transistor density, and 4.1 times the FP32 throughput indicate the RTX PRO 4500 was designed for substantially heavier workloads. The Arc A580's nearest rival cluster, all within 1.1%, shows it competes in a crowded mid-range segment, whereas the RTX PRO 4500 has no recorded rivals to contextualize its position.
