Intel Arc B370 vs NVIDIA RTX PRO 4500 Blackwell Comparison

Intel Arc B370 and NVIDIA RTX PRO 4500 Blackwell occupy opposite ends of the performance spectrum according to the recorded data. The Intel part is an integrated graphics processor (IGP) designed for compact, low-power systems, while the NVIDIA card is a dual-slot, PCIe 5.0 add-in board aimed at professional workloads. Their benchmark results show a massive gap, but the data also reveals distinct architectural philosophies that explain why each product exists.

Where Each One Wins

Based on the single shared benchmark in the database, the 3DMark Steel Nomad DX12 test, the NVIDIA RTX PRO 4500 Blackwell wins outright. It scores 7025 points compared to the Intel Arc B370's 1184 points, a difference of 83.1 percent in NVIDIA's favor. The Intel Arc B370 records zero benchmark wins in the head-to-head comparison, while NVIDIA captures all one available test.

The Intel Arc B370's strength lies not in raw performance but in its physical characteristics. It is an IGP with no power connectors, a 25 W TDP, and a system-shared memory architecture. This makes it suitable for portable devices where discrete graphics cards cannot fit. Its benchmark percentile of 5 places it among the lowest-scoring GPUs in the database, but its nearest rivals, such as the ATI Mobility Radeon HD 5570 and AMD Radeon HD 7650M, are similarly positioned, confirming its role as an entry-level integrated solution.

The NVIDIA RTX PRO 4500 Blackwell, by contrast, sits at the 76th percentile of all GPUs. Its average benchmark score of 31532 dwarfs the Intel part's 1184 average. The nearest rivals for NVIDIA include the NVIDIA TITAN RTX, NVIDIA GRID M60-1Q, and NVIDIA Quadro M5000, with score deltas of -0.5, 1, and 1 percent respectively. This clustering indicates the RTX PRO 4500 Blackwell performs in the upper tier of professional workstation graphics, a completely different market segment from the Intel IGP.

Architecture Differences

The two GPUs come from fundamentally different design lineages. The Intel Arc B370 uses the Panther Lake chip built on Xe3-LPG architecture, manufactured on Intel's 3 nm process. The NVIDIA RTX PRO 4500 Blackwell uses the GB203 chip built on Blackwell 2.0 architecture, manufactured by TSMC on a 5 nm process. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

The compute resources differ by an order of magnitude. Intel's Arc B370 has 1280 shading units, 40 texture mapping units, 20 raster operation units, and 10 ray tracing cores. NVIDIA's RTX PRO 4500 Blackwell has 10496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The NVIDIA card also includes dedicated tensor cores for AI workloads, which the Intel part lacks entirely.

Memory architecture separates the two completely. The Intel Arc B370 uses system-shared memory with a system-dependent bus width and bandwidth. The NVIDIA RTX PRO 4500 Blackwell has 32 GB of GDDR7 memory on a 256-bit bus, delivering 896.0 GB/s of bandwidth. The Intel part's memory clock is listed as system shared, while NVIDIA runs at 1750 MHz with 28 Gbps effective speed.

Head-to-Head Benchmarks

The only direct benchmark comparison in the database is 3DMark Steel Nomad DX12. The Intel Arc B370 scores 1184, while the NVIDIA RTX PRO 4500 Blackwell scores 7025. The delta percentage is -83.1 percent, meaning the Intel part delivers less than one-sixth of the NVIDIA card's performance in this test.

To contextualize the Intel score, its nearest rivals in the database are ATI Mobility Radeon HD 5570 (avg score 1186, delta -0.2 percent), ATI Radeon HD 5770 (avg score 1190, delta -0.5 percent), AMD Radeon HD 7650M (avg score 1192, delta -0.7 percent), and AMD FirePro M2000 (avg score 1168, delta 1.4 percent). All four rivals score within 1.4 percent of the Intel Arc B370, indicating the integrated part performs at the level of early-2010s discrete mobile GPUs.

For NVIDIA, the nearest rivals are NVIDIA TITAN RTX (avg score 31676, delta -0.5 percent), NVIDIA GRID M60-1Q (avg score 31220, delta 1 percent), NVIDIA Quadro M5000 (avg score 31206, delta 1 percent), and Intel Arc Pro A30M (avg score 31894, delta -1.1 percent). The RTX PRO 4500 Blackwell's average score of 31532 sits within 1.1 percent of all four, showing consistent performance against older high-end workstation cards.

The Verdict

The data indicates two products for two entirely separate use cases. The Intel Arc B370, with its 25 W TDP, IGP form factor, and system-shared memory, serves portable devices where space and power are constrained. Its benchmark percentile of 5 and score of 1184 in 3DMark Steel Nomad place it at entry-level performance, comparable to decade-old discrete mobile GPUs. Users requiring basic graphics acceleration in a thin-and-light device would find this part adequate.

The NVIDIA RTX PRO 4500 Blackwell, with its 200 W TDP, dual-slot design, 32 GB GDDR7 memory, and 50.53 TFLOPS FP32, targets professional workstation workloads. Its 76th percentile ranking and 7025 Steel Nomad score confirm it handles demanding 3D rendering, compute, and AI tasks. The 328 tensor cores provide dedicated hardware for neural network inference, a feature absent from the Intel part.

The 83.1 percent performance gap in the head-to-head test is not a flaw in either product but a reflection of their intended markets. The Intel Arc B370's nearest rivals are all mobile or low-end desktop GPUs from the early 2010s, while the NVIDIA card competes with the NVIDIA TITAN RTX and Quadro M5000. Any purchaser choosing between these two would be deciding between an integrated solution for a portable device and a professional workstation card, not between two similar options. The benchmark data simply confirms that NVIDIA holds the absolute performance advantage, while Intel offers the integrated form factor that NVIDIA does not provide in this comparison.
