The Verdict

The data separates these two cards into distinct roles. For raw compute throughput, the RTX PRO 4500 is the clear leader: its FP32 figure of 50.53 TFLOPS is roughly 2.57 times the Arc B770's 19.66 TFLOPS. Its shading unit count of 10496 versus 4096 confirms a fundamentally larger execution engine. The RTX PRO 4500 also carries twice the memory (32 GB versus 16 GB) with a higher bandwidth of 896.0 GB/s against 512.0 GB/s, and it supports PCIe 5.0 x16 instead of the Arc B770's PCIe 4.0 x16.

The Intel Arc B770, however, is not without its own merits. It has a higher base clock (2100 MHz versus 1635 MHz) and a higher pixel rate (307.2 GPixel/s versus 269.6 GPixel/s). It also uses more conventional power connectors, which may suit certain system configurations. The Arc B770's 50th percentile ranking versus all GPUs places it mid-pack, while the RTX PRO 4500 sits at the 76th percentile, indicating the NVIDIA card positions significantly higher in the overall performance distribution.

Users who need large memory capacity, high compute throughput, and modern PCIe bandwidth should choose the RTX PRO 4500. Users who prioritize pixel fill rate and simpler power delivery, and who do not require the higher compute ceiling, may find the Arc B770 sufficient for their workloads. The data does not indicate any scenario where the Arc B770 outperforms the RTX PRO 4500 in compute-bound tasks, but its lower TDP of 225 W versus 200 W is not a deciding factor either, as the NVIDIA card actually draws less power.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database contains no entries, so direct paired comparisons are unavailable. Instead, the analysis relies on the individual recorded measurements for the RTX PRO 4500 and the architectural specifications of both cards.

The RTX PRO 4500's Passmark G3D score of 33360 demonstrates strong rasterization performance. Its Passmark GPU Compute score of 19255 reflects substantial compute capability, consistent with its 50.53 TFLOPS FP32 rating. The 3DMark Steel Nomad DX12 score of 7025 indicates solid DirectX 12 performance, while the Geekbench Vulkan score of 221768 shows strong cross-API capability. The Passmark DirectX 11 score of 320 and DirectX 10 score of 204 provide additional reference points, though these are not directly comparable to the Arc B770 since that card has no recorded benchmarks.

The Arc B770's absence of benchmark data means its performance must be inferred from its specifications. Its FP32 throughput of 19.66 TFLOPS is less than half of the RTX PRO 4500's 50.53 TFLOPS. Its texture rate of 614.4 GTexel/s is lower than the RTX PRO 4500's 789.5 GTexel/s. Its pixel rate of 307.2 GPixel/s, however, exceeds the RTX PRO 4500's 269.6 GPixel/s, which is the one area where the Arc B770 holds a measurable advantage.

The RTX PRO 4500's average benchmark score of 31532 places it in the 76th percentile. Its nearest rivals, the NVIDIA TITAN RTX at 31676 and Intel Arc Pro A30M at 31894, are within 1.1% either way. This clustering indicates the RTX PRO 4500 performs in a tightly competitive band. The Arc B770's 50th percentile ranking suggests it sits in the middle of the overall distribution, well below the RTX PRO 4500's position.

Architecture Differences

The architectural divide is fundamental. The Intel Arc B770 uses the Xe2-HPG architecture from the Battlemage generation, built on TSMC's 5 nm process. The NVIDIA RTX PRO 4500 uses the Blackwell 2.0 architecture from the Blackwell PRO W generation, also on TSMC's 5 nm process. Die sizes are close: 368 mm² for Intel versus 378 mm² for NVIDIA, but the transistor counts differ dramatically. The RTX PRO 4500 contains 45,600 million transistors with a density of 120.6M per mm², while the Arc B770's transistor count is listed as unknown.

The compute architecture diverges in capability. The RTX PRO 4500 integrates 328 tensor cores, which the Arc B770 lacks entirely. The NVIDIA card also has 82 ray tracing cores versus 32 on the Intel card, indicating a much larger ray tracing throughput potential. The FP16 performance tells a different story: the Arc B770 achieves 39.32 TFLOPS at a 2:1 ratio relative to FP32, while the RTX PRO 4500 achieves 50.53 TFLOPS at a 1:1 ratio. This means the NVIDIA card maintains full throughput for FP16 workloads, while the Intel card halves its rate.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The memory architecture differs by generation: GDDR7 on the NVIDIA card versus GDDR6 on the Intel card, with correspondingly higher effective speed on the NVIDIA card (28 Gbps versus 16 Gbps). The bus interface generation also differs, with PCIe 5.0 on the NVIDIA card and PCIe 4.0 on the Intel card, doubling the potential host bandwidth for the RTX PRO 4500.

The Intel card's predecessor is Alchemist, while the NVIDIA card's predecessor is Workstation Ada. Neither card has a listed successor. The NVIDIA card has a production status of Active, indicating current availability, while the Intel card's status is not recorded.

Where Each One Wins

The RTX PRO 4500 wins decisively in compute-heavy workloads. Its FP32 throughput of 50.53 TFLOPS, FP16 throughput of 50.53 TFLOPS, and 10496 shading units provide a massive parallel processing advantage. Applications that rely on general-purpose GPU compute, such as rendering, simulation, or data processing, will see substantially higher throughput on the NVIDIA card. Its 328 tensor cores add dedicated AI acceleration hardware that the Intel card does not have, making the RTX PRO 4500 the only choice for tensor-based workloads. The 32 GB memory capacity and 896.0 GB/s bandwidth support larger datasets and faster memory access than the Arc B770's 16 GB and 512.0 GB/s.

The Arc B770 wins in pixel throughput. Its pixel rate of 307.2 GPixel/s exceeds the RTX PRO 4500's 269.6 GPixel/s, indicating faster fill-rate performance for pixel-bound operations. Its higher base clock of 2100 MHz versus 1635 MHz suggests better sustained performance at lower workloads. The Arc B770 also uses a more traditional power connector setup, which may simplify installation in systems without 16-pin cabling. Its lower shading unit count and texture rate, however, limit its overall compute capability.

For memory bandwidth, the RTX PRO 4500 wins with 896.0 GB/s versus 512.0 GB/s, a 75% advantage. For texture throughput, the RTX PRO 4500 wins with 789.5 GTexel/s versus 614.4 GTexel/s, a 28% advantage. For ray tracing, the RTX PRO 4500's 82 RT cores versus 32 provide more than double the ray tracing hardware. For interface bandwidth, PCIe 5.0 x16 versus PCIe 4.0 x16 gives the NVIDIA card a clear host transfer advantage.

The benchmark percentile ranking reinforces this split. The RTX PRO 4500 sits at the 76th percentile with an average score of 31532, while the Arc B770 sits at the 50th percentile with no recorded average score. The NVIDIA card's nearest rivals cluster within 1.1%, showing it competes at a high level. The Intel card has no rival data recorded, leaving its competitive position defined only by its mid-pack percentile.
