Architecture Differences

The architectural divide between the two cards is substantial. The Intel Arc B570 is built on the Xe2-HPG architecture, part of the Battlemage generation (Arc 5). It uses the BMG-G21 chip. In contrast, the NVIDIA RTX PRO 4500 Blackwell Workstation employs the Blackwell 2.0 architecture, with the GB203 chip, and belongs to the Blackwell PRO W (x000) generation. Both are fabricated by TSMC on a 5 nm process, but the physical implementations diverge sharply. The Intel die measures 272 mm² and holds 19,600 million transistors, yielding a transistor density of 72.1M per mm². The NVIDIA die is larger at 378 mm² and packs 45,600 million transistors, resulting in a density of 120.6M per mm², which indicates a significantly more crowded transistor layout.

Core configuration differs by a wide margin. The Arc B570 has 2304 shading units, 144 texture mapping units (TMUs), 80 raster operations units (ROPs), and 18 ray tracing cores. The RTX PRO 4500 comes with 10496 shading units, 328 TMUs, 112 ROPs, 82 ray tracing cores, and 328 tensor cores. The Intel card does not list tensor cores in its specification, while the NVIDIA card’s tensor core count matches its TMU count. This suggests a fundamentally different compute philosophy: the NVIDIA card is designed for parallel workloads that leverage both ray tracing and tensor operations, whereas the Intel card focuses on a more conventional shading pipeline.

Clock speeds also tell a story. The Arc B570 operates at a constant 2500 MHz for both base and boost clocks, which is a modest but steady frequency. The RTX PRO 4500 has a base clock of 1635 MHz and a boost clock of 2407 MHz, indicating a larger dynamic range and a peak frequency that approaches but does not exceed the Intel card’s boost. Memory clocks differ as well: the Intel card runs at 2375 MHz with 19 Gbps effective, while the NVIDIA card runs at 1750 MHz with 28 Gbps effective. The NVIDIA memory is faster in effective data rate despite a lower physical clock, due to the GDDR7 standard.

The feature sets are similar in terms of API support: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. However, connectivity and output options differ. The Arc B570 uses a PCIe 4.0 x8 interface and provides 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs. The RTX PRO 4500 uses a PCIe 5.0 x16 interface and offers 4x DisplayPort 2.1b outputs, which is a newer DisplayPort revision. Power delivery also diverges: the Intel card uses a 1x 8-pin connector and a suggested 450 W PSU, while the NVIDIA card uses a 1x 16-pin connector and a suggested 550 W PSU. The NVIDIA card has a higher TDP at 200 W versus the Intel card’s 150 W.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Arc B570 and the RTX PRO 4500. The RTX PRO 4500 has an empty benchmark list, an average benchmark score of zero, and no nearest rivals. This absence of recorded data means that no direct performance comparison can be made from our measurements. However, the Arc B570 has extensive benchmark data that places it within a specific performance tier.

The Arc B570 achieves an average benchmark score of 20556 across its recorded tests. Its percentile rank among all GPUs is 65, which indicates that it outperforms a majority of graphics cards in the database. The individual benchmark scores show a wide spread. In 3DMark Steel Nomad (DX12), it scores 2649 points. In Geekbench tests, it reaches 83514 in OpenCL and 96844 in Vulkan. Passmark tests show scores of 65 in DirectX 10, 118 in DirectX 11, 72 in DirectX 12, 164 in DirectX 9, 661 in G2D, 14195 in G3D, and 7281 in GPU Compute.

The nearest rivals for the Arc B570, based on average scores, include the NVIDIA GeForce RTX 3070 Mobile with an average score of 20534 and a delta of 0.1%, the Intel Arc A750 with an average score of 20582 and a delta of -0.1%, the NVIDIA Quadro M4000M with an average score of 20480 and a delta of 0.4%, and the AMD Radeon R9 M390X with an average score of 20662 and a delta of -0.5%. These deltas are all within one percent, indicating that the Arc B570 sits in a tightly contested performance band where small variations separate cards. The closest competitor is the Arc A750, which trails the B570 by just 0.1% in average score, while the Quadro M4000M is slightly ahead by 0.4%.

Since the RTX PRO 4500 has no benchmark data, the head-to-head analysis must be inferred from specifications. The NVIDIA card’s FP32 throughput of 50.53 TFLOPS is 4.4 times the Arc B570’s 11.52 TFLOPS. Texture rate follows a similar pattern: 789.5 GTexel/s versus 360.0 GTexel/s, a 2.2 times advantage. Pixel rate favors the NVIDIA card at 269.6 GPixel/s versus 200.0 GPixel/s, a 1.3 times difference. Memory bandwidth is 2.4 times higher on the NVIDIA card. These specification gaps suggest that the RTX PRO 4500 would dominate in compute-heavy and bandwidth-intensive workloads, but without measured scores, the actual performance delta remains unquantified.

The Verdict

The recorded data indicates that the Intel Arc B570 is a fully measured product with a 65th percentile rank and an average score of 20556, placing it in the middle-upper tier of all GPUs. Its nearest rivals are all within 0.5% of its average score, which shows that it competes directly with mobile and older desktop parts like the RTX 3070 Mobile, Arc A750, Quadro M4000M, and R9 M390X. The NVIDIA RTX PRO 4500 Blackwell Workstation, by contrast, has no benchmark results in the database, no average score, and no rival comparisons. Its specifications, however, are far above the Intel card in nearly every compute metric.

For users selecting between these two, the data points to different use cases. The Arc B570 is a proven performer with a known benchmark profile, a lower TDP of 150 W, and a smaller memory footprint of 10 GB. The RTX PRO 4500 offers 32 GB of GDDR7 memory, 896.0 GB/s bandwidth, 50.53 TFLOPS FP32, and a PCIe 5.0 x16 interface, which are workstation-class features. The absence of benchmarks for the NVIDIA card means that its real-world performance cannot be verified from the database, but the specification gap is so large that it would likely dominate in professional workloads such as rendering, scientific simulation, or AI inference, where tensor cores and high memory capacity matter.

The Intel card’s percentile of 65 versus the NVIDIA card’s percentile of 50 (which is based on an average score of zero, effectively a placeholder) does not reflect actual performance; the percentile for the RTX PRO 4500 is not meaningful without recorded scores. The verdict from the data is clear: the Arc B570 is a validated mid-range option, while the RTX PRO 4500 is an unmeasured but spec-heavy workstation card. The choice depends on whether the user prioritizes verified benchmark results or the potential of a much larger compute and memory resource.

Where Each One Wins

The Intel Arc B570 wins in areas where its benchmark data provides concrete evidence. It has a higher base and boost clock of 2500 MHz, which is above the NVIDIA card’s boost of 2407 MHz, suggesting an advantage in lightly threaded or clock-sensitive tasks. It also has a lower TDP of 150 W, which implies lower power draw, and a smaller die at 272 mm², which may translate to lower manufacturing complexity. The Arc B570’s launch MSRP of 219 USD is a recorded fact, though the analysis avoids pricing commentary. Its PCIe 4.0 x8 interface is older but sufficient for many workloads. The benchmark scores show it performs competitively with the RTX 3070 Mobile and Arc A750, with deltas of 0.1% or less, meaning it trades wins in that performance class.

The NVIDIA RTX PRO 4500 wins in specification-based comparisons. It has 4.4 times the FP32 throughput, 2.2 times the texture rate, 1.3 times the pixel rate, and 2.4 times the memory bandwidth. It has 32 GB of GDDR7 memory versus 10 GB of GDDR6, a 256-bit bus versus 160-bit, and 82 RT cores versus 18. It also has 328 tensor cores, which the Intel card lacks entirely. The NVIDIA card supports PCIe 5.0 x16, doubling the lane width and generation of the Intel card’s PCIe 4.0 x8. Its memory clock effective rate is 28 Gbps versus 19 Gbps. The transistor density is 120.6M / mm² versus 72.1M / mm², indicating a more tightly packed and potentially more efficient design per area. The NVIDIA card also uses GDDR7 memory, a newer standard, and has four DisplayPort 2.1b outputs versus the Intel card’s one HDMI and three DisplayPort 2.1 outputs.

For FP16 compute, the NVIDIA card achieves 50.53 TFLOPS at a 1:1 ratio, while the Intel card achieves 23.04 TFLOPS at a 2:1 ratio, meaning the NVIDIA card’s FP16 performance is not only higher but also does not rely on a packed math rate. The RTX PRO 4500’s 200 W TDP is higher, but it delivers more than four times the FP32 throughput per watt when comparing raw figures, though efficiency ratios are not directly recorded. The data indicates that the NVIDIA card is designed for maximum throughput in professional environments, while the Intel card is a balanced, lower-power option with a proven benchmark footprint.
