Intel Arc B390 vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

Intel Arc B390 and NVIDIA RTX PRO 4500 Blackwell Server represent two vastly different segments of the graphics hardware market. The database records show that the Arc B390 has a single benchmark score, while the RTX PRO 4500 has no recorded benchmark scores. This presents a direct comparison challenge, but the specification data and the limited performance metric provide a clear picture of their respective positions.

Head-to-Head Benchmarks

The only direct benchmark score available in the database is for the Intel Arc B390. It records a score of 1482 in the 3DMark Steel Nomad DX12 test. This result places the Arc B390 in the 9th percentile of all GPUs, indicating that it performs at a level well below the vast majority of graphics cards in the database.

The NVIDIA RTX PRO 4500 Blackwell Server has no benchmark scores recorded in the database. Its average benchmark score is listed as 0, and its percentile rank is 50. This means the database has no direct measurement of its 3DMark Steel Nomad performance or any other graphics test. The absence of data for the RTX PRO 4500 is notable, given its position as a server-class part designed for compute workloads rather than consumer gaming benchmarks.

For the Arc B390, the nearest rivals in the database are all older NVIDIA GeForce parts. The data shows the Arc B390 is 1.3% ahead of the GeForce GT 520MX, 1.5% ahead of the GeForce 800M, 2.5% ahead of the GeForce GT 625 OEM, and 2.7% ahead of the GeForce GT 710. These are extremely small margins, placing the Arc B390 in the same performance tier as decade-old entry-level graphics solutions. The 1482 score is a very low figure, and the 9th percentile rank confirms that this is not a competitive gaming or workstation part by modern standards.

The RTX PRO 4500 has no rivals listed in the database because no benchmark data exists to compare against. Its 50th percentile rank is a default value, not a measurement. The head-to-head comparison is therefore one-sided: the Arc B390 has a recorded score that places it near the bottom of the performance scale, while the RTX PRO 4500 has no recorded score at all.

Where Each One Wins

Based on the recorded data, the Intel Arc B390 wins in the only benchmark category where a measurement exists. It delivers a 3DMark Steel Nomad DX12 score of 1482, which is a real, measurable result. The NVIDIA RTX PRO 4500 cannot win in this test because it has no recorded score. In terms of raw performance data, the Arc B390 is the only part with verifiable graphics output.

However, the data suggests different strengths for each product. The Arc B390 is an integrated graphics processor (IGP) with a 3 nm process node from Intel. Its low score and 9th percentile ranking indicate that its strength lies in basic rendering tasks, likely for mobile or low-power devices where a discrete GPU is not an option. The RTX PRO 4500, by contrast, is a server part with no display outputs. Its design targets compute environments, not visual rendering. The absence of benchmarks for the RTX PRO 4500 does not necessarily mean it is slower; it means the database lacks the specific test data to assess its graphics performance. The Arc B390 wins the only measurable benchmark, but the RTX PRO 4500 is built for a different category of workload altogether.

The specification data supports this split. The Arc B390 has 1536 shading units, 48 texture mapping units, and 24 render output units. The RTX PRO 4500 has 10496 shading units, 328 texture mapping units, and 112 render output units. These are enormous differences in raw compute resources. The RTX PRO 4500 also has 82 ray tracing cores and 328 tensor cores, while the Arc B390 has 12 ray tracing cores and no tensor core data. This suggests the RTX PRO 4500 is designed for heavy parallel compute and AI workloads, while the Arc B390 is a basic integrated solution.

Architecture Differences

The Intel Arc B390 uses the Xe3-LPG architecture with the Panther Lake chip. It is built on a 3 nm process at Intel's foundry. The architecture generation is listed as Arc Graphics-M (Panther Lake). This is a low-power integrated design. The NVIDIA RTX PRO 4500 uses the Blackwell 2.0 architecture with the GB203 chip. It is built on a 5 nm process at TSMC. The generation is Server Blackwell (Bxx). The process node difference is notable: the Arc B390 uses a newer 3 nm node, while the RTX PRO 4500 uses a 5 nm node. However, the RTX PRO 4500 has a much larger physical implementation. The database records 45,600 million transistors on a 378 mm² die for the RTX PRO 4500, with a transistor density of 120.6 million per mm². The Arc B390 has unknown transistor counts and die size.

The memory systems are fundamentally different. The Arc B390 uses system shared memory, meaning there is no dedicated VRAM. Its memory type is system shared, the bus width is system shared, and the bandwidth is system dependent. The RTX PRO 4500 has 32 GB of GDDR7 memory on a 256-bit bus, delivering 800.3 GB/s of bandwidth. The memory clock for the RTX PRO 4500 is 1563 MHz, with a 25 Gbps effective rate. This is a massive difference in memory capacity and speed, reflecting the different roles of the two parts.

The RTX PRO 4500 also includes features that the Arc B390 lacks. It has tensor cores (328 of them) and a higher count of ray tracing cores (82 versus 12). Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical. The power profiles differ significantly: the Arc B390 has a TDP of 80 W and requires no power connectors, while the RTX PRO 4500 has a TDP of 165 W and uses a single 16-pin connector with a suggested power supply of 450 W.

The Verdict

The data shows two products with no meaningful overlap. The Intel Arc B390 is an integrated GPU with a 3 nm process, 80 W TDP, and system shared memory. Its single benchmark score of 1482 places it in the 9th percentile, just 1.3% ahead of the GeForce GT 520MX and 2.7% ahead of the GeForce GT 710. This is entry-level performance suitable for basic display output and light rendering on a portable device.

The NVIDIA RTX PRO 4500 Blackwell Server is a discrete server card with 32 GB GDDR7, 10496 shading units, 328 tensor cores, and a 165 W TDP. It has no recorded benchmark scores, but its specification sheet indicates a compute-focused design with no display outputs. The FP32 throughput of 50.70 TFLOPS is over six times the Arc B390's 7.680 TFLOPS, and the texture rate of 792.1 GTexel/s is more than six times higher.

For users requiring a measurable graphics benchmark, the Arc B390 is the only option with data, but that data is not favorable. For users requiring a server compute accelerator with large memory and high throughput, the RTX PRO 4500 is the clear choice based on specifications alone. The Arc B390 should be selected for low-power integrated graphics in a mobile or compact system. The RTX PRO 4500 should be selected for server environments where raw compute power and 32 GB of GDDR7 memory are required. The benchmark data does not support the RTX PRO 4500, but the specification differences confirm that these are different classes of hardware.
