Memory clocks also differ, with Intel at 2375 MHz (19 Gbps effective) and NVIDIA at 1750 MHz (28 Gbps effective).
The NVIDIA card supports FP16 at a 1:1 ratio with FP32, meaning it processes both at 50.53 TFLOPS. The Intel card processes FP16 at a 2:1 ratio, delivering 45.88 TFLOPS, which is exactly double its FP32 throughput of 22.94 TFLOPS.
Where Each One Wins
The data indicates distinct strengths for each card depending on the workload type. The NVIDIA RTX PRO 4500 Blackwell dominates in raw compute throughput, delivering 50.53 TFLOPS of FP32 performance, which is 2.2x the 22.94 TFLOPS of the Intel Arc Pro B70. This advantage extends to FP16 workloads, where NVIDIA's 50.53 TFLOPS exceeds Intel's 45.88 TFLOPS, though by a smaller margin.
Texture processing favors the NVIDIA card, with 789.5 GTexel/s compared to 716.8 GTexel/s for the Intel card. This suggests NVIDIA has an edge in workloads heavily dependent on texture sampling and filtering. The NVIDIA card also benefits from its 328 tensor cores, enabling accelerated AI and machine learning tasks that the Intel card cannot match without tensor core hardware.
The Intel Arc Pro B70 wins in pixel throughput, delivering 358.4 GPixel/s compared to 269.6 GPixel/s for the NVIDIA card.

Head-to-Head Benchmarks
The database contains no direct head-to-head benchmark results between the Intel Arc Pro B70 and the NVIDIA RTX PRO 4500 Blackwell. However, the recorded performance metrics for each card allow for meaningful comparison across compute categories.
The largest single advantage for the NVIDIA card is in FP32 compute. NVIDIA's 50.53 TFLOPS is 27.59 TFLOPS higher than Intel's 22.94 TFLOPS, representing a 2.2x difference. This is the most decisive gap between the two cards and indicates NVIDIA's clear superiority in general-purpose compute workloads.
In FP16 performance, NVIDIA maintains its lead with 50.53 TFLOPS versus 45.88 TFLOPS, a difference of 4.65 TFLOPS. This margin is smaller because Intel's FP16 throughput benefits from a 2:1 ratio, effectively doubling its FP32 rate. For workloads that can use FP16 precision, the Intel card closes some of the gap.
Texture rate favors NVIDIA by 72.7 GTexel/s (789.5 versus 716.8). This 10% advantage suggests NVIDIA handles texture-heavy workloads better, despite having fewer ROPs. The NVIDIA card's higher shading unit count likely contributes to this texture processing advantage.
Pixel rate favors Intel by 88.8 GPixel/s (358.4 versus 269.6), a 33% advantage. This is the Intel card's most significant win and indicates stronger fill-rate performance. The higher ROP count of 128 versus 112 and the higher boost clock of 2800 MHz support this result.
Memory bandwidth gives NVIDIA a 288 GB/s advantage (896.0 versus 608.0), a 47% difference. This becomes critical in bandwidth-bound scenarios such as large model inference, high-resolution rendering with massive textures, or multi-display output.
The NVIDIA card's recorded benchmarks show an average score of 31532, with a 3DMark Steel Nomad DX12 score of 7025 and a Geekbench Vulkan score of 221768. Its Passmark G3D score of 33360 and Passmark GPU Compute score of 19255 provide additional data points. The nearest rivals in the database include the NVIDIA TITAN RTX with an average score of 31676 (0.5% higher) and the Intel Arc Pro A30M with a score of 31894 (1.1% higher), though these are not direct comparisons to the Intel Arc Pro B70.
The Verdict
The recorded data supports a clear split in use cases between the Intel Arc Pro B70 and the NVIDIA RTX PRO 4500 Blackwell. For compute-intensive professional workloads, the NVIDIA card is the decisive choice. Its 50.53 TFLOPS FP32 performance more than doubles the Intel card's 22.94 TFLOPS, and its 328 tensor cores provide dedicated hardware for AI acceleration that the Intel card lacks entirely.
The NVIDIA card also wins on memory bandwidth at 896.0 GB/s, a 47% advantage over the Intel card's 608.0 GB/s. Combined with GDDR7 memory and a higher texture rate of 789.5 GTexel/s, the NVIDIA card is better suited for data-heavy rendering, large model processing, and tasks where bandwidth is the limiting factor.
The Intel Arc Pro B70 delivers its strongest showing in pixel throughput, with 358.4 GPixel/s versus 269.6 GPixel/s for the NVIDIA card. This 33% advantage in fill rate, along with a higher boost clock of 2800 MHz, makes the Intel card competitive for rasterization-bound workflows where pixel output is the bottleneck. Its lower FP32 throughput means it cannot match NVIDIA in general compute, but for specific rendering pipelines, the pixel rate advantage matters.
The power profile favors NVIDIA as well, with a TDP of 200 W versus 230 W for Intel, despite the NVIDIA card delivering more than double the FP32 compute. This efficiency advantage is noteworthy for multi-GPU configurations or constrained power environments.
The percentile data reinforces the performance gap. The NVIDIA RTX PRO 4500 Blackwell sits at the 76th percentile among all GPUs in the database, while the Intel Arc Pro B70 sits at the 50th percentile. The NVIDIA card's average benchmark score of 31532 places it among strong performers, with nearest rivals within 1% of its score.
Users requiring maximum compute throughput, AI acceleration, or memory bandwidth should select the NVIDIA RTX PRO 4500 Blackwell. Users prioritizing pixel fill rate and working within rasterization-heavy pipelines may find the Intel Arc Pro B70 sufficient, though the overall compute gap remains substantial. The release timing also matters, with NVIDIA launching on 2025-03-17 and Intel on 2026-03-25, making the NVIDIA card a more mature product in the market.
