Intel Arc Pro B65 vs NVIDIA GeForce RTX 5050 Comparison

Intel Arc Pro B65 vs NVIDIA GeForce RTX 5050

The database records a clear split in performance characteristics between these two active GPUs. The NVIDIA GeForce RTX 5050 holds the only benchmark scores listed, yet the Intel Arc Pro B65’s specification sheet reveals a design aimed at a different workload profile. The RTX 5050 achieves an average benchmark score of 21,035, placing it in the 66th percentile of all GPUs, while the Arc Pro B65 sits at the 50th percentile with an average score of 0, indicating no recorded benchmark data in the database. This absence of direct head-to-head measurements means the comparison rests on architectural specifications and the RTX 5050’s available test results.

Head-to-Head Benchmarks

The RTX 5050’s benchmark results show a range of performance across different APIs and workloads. In 3DMark Steel Nomad DX12, it scores 2,502, a modest result for a modern GPU. Geekbench OpenCL returns 90,334, and Geekbench Vulkan returns 89,381, showing strong compute capabilities in those frameworks. Passmark results paint a mixed picture: DirectX 10 scores 103, DirectX 11 scores 150, DirectX 12 scores 66, and DirectX 9 scores 186. The Passmark G3D score of 17,326 and GPU Compute score of 9,184 indicate substantial raw graphics and compute throughput, while the G2D score of 1,113 covers 2D operations.

Since the Arc Pro B65 has no benchmark entries, the nearest rivals for the RTX 5050 provide context. The AMD Radeon RX Vega M GL scores 21,153, which is 0.6% above the RTX 5050, and the AMD Radeon HD 8970M scores 21,237, 1% higher. The AMD Radeon RX 5600 XT trails by 1.6% with 20,713, and the NVIDIA RTX A4000 Mobile leads by 1.6% with 21,379. These deltas are small, indicating the RTX 5050 performs in a narrow band around these older and mobile parts, despite its newer architecture. The data suggests the RTX 5050 is not a top-tier performer but rather a mid-range card that competes closely with several generations-old GPUs.

Architecture Differences

The two GPUs share a 5 nm process node at TSMC but diverge in nearly every other architectural aspect. The Intel Arc Pro B65 uses the Xe2-HPG architecture on the BMG-G21 chip, belonging to the Battlemage (Pro Series) generation. It integrates 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1 million per mm². The NVIDIA GeForce RTX 5050 uses Blackwell 2.0 on the GB207 chip from the GeForce 50 generation. It packs 16,900 million transistors onto a smaller 149 mm² die, achieving a higher density of 113.4 million per mm². This means NVIDIA fits nearly the same transistor count into 55% of the silicon area, indicating a more compact design.

Memory configurations differ significantly. The Arc Pro B65 offers 32 GB of GDDR6 on a 256-bit bus, delivering 608.0 GB/s of bandwidth. The RTX 5050 has 8 GB of GDDR6 on a 128-bit bus, providing 320.0 GB/s. The Intel card has four times the memory capacity and nearly double the bandwidth. Clock speeds also differ: the Arc Pro B65 runs at a flat 2400 MHz base and boost, while the RTX 5050 has a 2317 MHz base and 2572 MHz boost. Memory clocks see the RTX 5050 at 2500 MHz (20 Gbps effective) versus 2375 MHz (19 Gbps effective) for the Intel card. Both use the same shading unit count of 2,560, but the RTX 5050 has 80 tensor cores, a feature absent from the Arc Pro B65’s specification sheet. The RTX 5050 also has 20 RT cores, matching the Intel card’s 20, but the NVIDIA card’s architecture supports Tensor operations, which the Intel card does not list.

Where Each One Wins

The Intel Arc Pro B65 wins decisively in memory capacity and bandwidth, offering 32 GB versus 8 GB and 608.0 GB/s versus 320.0 GB/s. Its texture rate of 384.0 GTexel/s doubles the RTX 5050’s 205.8 GTexel/s, and its pixel rate of 192.0 GPixel/s more than doubles the NVIDIA card’s 82.30 GPixel/s. The Intel card’s FP16 throughput of 24.58 TFLOPS exceeds the RTX 5050’s 13.17 TFLOPS by 86%, indicating stronger compute for workloads that leverage half-precision. The wider PCIe 5.0 x16 interface also provides more host bandwidth than the RTX 5050’s x8 link.

The NVIDIA GeForce RTX 5050 wins in raw FP32 performance, delivering 13.17 TFLOPS versus 12.29 TFLOPS, a 7% advantage. It has a higher boost clock at 2572 MHz versus 2400 MHz and a higher memory clock at 2500 MHz versus 2375 MHz. The inclusion of 80 tensor cores gives it a feature that the Intel card lacks entirely, suggesting an edge in AI-accelerated workloads. Its lower TDP of 130 W and suggested PSU of 300 W make it a more power-efficient option compared to the Intel card’s 200 W and 550 W requirements. The RTX 5050 also carries benchmark data, including an average score of 21,035 and a 66th percentile ranking, while the Arc Pro B65 has no recorded scores.

The Verdict

The data indicates two distinct use cases. The Intel Arc Pro B65 targets workloads demanding large memory pools and high bandwidth, such as professional rendering or data-heavy compute, given its 32 GB capacity and 608.0 GB/s throughput. Its doubled texture and pixel rates support high-resolution texture work, and its superior FP16 performance suits half-precision compute tasks. The RTX 5050, with its 13.17 TFLOPS FP32, tensor cores, and lower power draw, fits general gaming and consumer applications where FP32 matters most and where power efficiency is a priority. Its benchmark scores, while modest, confirm functional performance across DirectX and compute APIs. The Arc Pro B65’s lack of benchmark data and 50th percentile standing versus the RTX 5050’s 66th percentile suggests the NVIDIA card holds a stronger measured position in the database. Buyers requiring massive memory and bandwidth should consider the Intel card, while those needing confirmed benchmark performance, tensor capabilities, or lower power consumption should lean toward the RTX 5050.
