Intel Arc B370 vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

Where Each One Wins

The recorded data presents an unusual comparison: the Intel Arc B370 has a single benchmark entry, while the NVIDIA RTX PRO 4500 Blackwell Server has no recorded benchmark scores at all. This means the direct head-to-head comparison cannot rely on identical test results. Instead, the analysis must split by use case based on what each component is designed to do and what the available data indicates.

The Intel Arc B370 is an integrated graphics processor, part of the Panther Lake mobile generation. Its 25 W TDP and IGP slot width place it firmly in the low-power, portable device segment. The single benchmark score of 1184 points in 3DMark Steel Nomad (DX12) positions it at the 5th percentile among all GPUs, which places it alongside older discrete mobile parts like the ATI Mobility Radeon HD 5570 (1186, -0.2%) and AMD Radeon HD 7650M (1192, -0.7%). The data shows this is a modest performer, suitable for light graphics workloads, basic gaming, or media acceleration in thin-and-light systems where power draw is the primary constraint.

The NVIDIA RTX PRO 4500 Blackwell Server, by contrast, is a professional server accelerator built on the GB203 chip with the Blackwell 2.0 architecture. Its specifications point to a completely different workload profile. With 32 GB of GDDR7 memory on a 256-bit bus delivering 800.3 GB/s of bandwidth, 10496 shading units, 82 RT cores, and 328 tensor cores, this is a compute-oriented card for AI inference, rendering, and large-scale data processing. Its 165 W TDP is modest for a server card, and its single-slot design with one 16-pin power connector targets dense rack deployments. The lack of display outputs confirms it is not meant for desktop use but for headless compute nodes.

The wins are therefore situational. The Arc B370 wins in the integrated, low-power, portable device space where no discrete GPU can fit. The RTX PRO 4500 wins in professional server workloads requiring substantial FP32 throughput (50.70 TFLOPS), high memory bandwidth, and tensor core acceleration. These are not competing products in the same market segment; they serve different physical and performance envelopes.

Architecture Differences

The two components diverge fundamentally in architecture, process technology, and feature sets. The Intel Arc B370 uses the Xe3-LPG architecture, built on Panther Lake with a 3 nm process node from Intel's own foundry. It is the integrated graphics solution for that platform, with a base clock of 300 MHz and a boost clock of 2400 MHz. Its memory subsystem is entirely system-shared, meaning it borrows from the host's main memory, with bandwidth described as system dependent. The chip has 1280 shading units, 40 texture mapping units, 20 raster output units, and 10 RT cores. FP32 performance is rated at 6.144 TFLOPS, with FP16 at 12.29 TFLOPS using a 2:1 ratio. The design is compact and power efficient, consuming only 25 W with no power connectors required.

The NVIDIA RTX PRO 4500 Blackwell Server uses the GB203 chip with Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The die contains 45,600 million transistors across 378 mm², yielding a transistor density of 120.6 million per mm². This is a massive compute chip compared to the Intel integrated solution. Its base clock is 1215 MHz with a boost of 2415 MHz, and it uses dedicated GDDR7 memory: 32 GB on a 256-bit bus with 800.3 GB/s bandwidth. The shading unit count is 10496, with 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. FP32 and FP16 performance are both 50.70 TFLOPS, indicating a 1:1 ratio rather than the 2:1 ratio on the Intel part.

The API support is identical on paper: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. However, the physical implementation differs sharply. The Intel part is an IGP, meaning it has no bus interface beyond the integrated package, no discrete dimensions, and its display outputs are portable device dependent. The NVIDIA part is a full PCIe 5.0 x16 add-in card, measuring 267 mm in length, 111 mm in height, and 40 mm in width, with no display outputs at all. The RTX PRO 4500 also carries a predecessor (Server Hopper) and successor (Server Rubin), indicating an active product cycle, while the Arc B370 has neither listed.

Head-to-Head Benchmarks

Direct benchmark comparison is limited because the database contains no head-to-head results and the NVIDIA part has no recorded scores. The only measurable data point is the Intel Arc B370's 3DMark Steel Nomad DX12 score of 1184. This places it at the 5th percentile among all GPUs, a low position that reflects its integrated nature.

The nearest rivals for the Arc B370 provide context. The ATI Mobility Radeon HD 5570 scores 1186, which is 0.2% higher than the Arc B370. The ATI Radeon HD 5770 scores 1190, 0.5% higher. The AMD Radeon HD 7650M scores 1192, 0.7% higher. The AMD FirePro M2000 scores 1168, which is 1.4% lower than the Arc B370. These are all older discrete parts, yet they perform at nearly identical levels in this test. The data indicates the Arc B370's integrated design achieves performance comparable to those legacy discrete GPUs, which is a notable result for an IGP.

For the RTX PRO 4500, no benchmark scores exist in the database. Its percentile vs all GPUs is listed at 50, which is the median position, though this appears to be a default or estimated value rather than a measured result. Without recorded scores, any head-to-head comparison must rely on architectural specifications rather than benchmark outcomes. The FP32 throughput difference is substantial: the RTX PRO 4500 delivers 50.70 TFLOPS versus 6.144 TFLOPS for the Arc B370, an 8.25x difference. Memory bandwidth is similarly divergent, with 800.3 GB/s dedicated bandwidth versus system-shared, system-dependent bandwidth for the Intel part. Pixel rate is 270.5 GPixel/s versus 48.00 GPixel/s, and texture rate is 792.1 GTexel/s versus 96.00 GTexel/s.

The absence of head-to-head data means the analysis cannot claim a measured win for either side. The specifications strongly suggest the NVIDIA part will dominate in compute-heavy workloads, while the Intel part is constrained to lighter tasks, but the database has not yet recorded a direct comparison.

The Verdict

The data supports a clear separation of use cases. The Intel Arc B370, with its 25 W TDP, integrated design, and 5th percentile benchmark position, is suited for portable devices where power efficiency matters more than raw performance. Its 1280 shading units and 6.144 TFLOPS FP32 throughput handle basic graphics tasks, and its 3DMark score of 1184 aligns with older discrete mobile GPUs. This is a component for lightweight workloads, not demanding compute.

The NVIDIA RTX PRO 4500 Blackwell Server is a professional compute accelerator. Its specifications indicate it is designed for server environments requiring high FP32 throughput (50.70 TFLOPS), large memory capacity (32 GB GDDR7), and tensor core acceleration (328 tensor cores). The lack of display outputs confirms it is not for interactive use. Its 165 W TDP and single-slot form factor make it suitable for dense server configurations. The predecessor and successor entries in the database show this is part of an active product generation cycle.

Who should pick which depends strictly on the workload. Systems requiring integrated graphics in a low-power mobile platform should choose the Intel Arc B370. Server deployments needing substantial compute, memory bandwidth, and AI acceleration should choose the NVIDIA RTX PRO 4500. The two do not compete in the same market, and the recorded data reflects that separation.
