Intel Arc Pro B65 vs NVIDIA GeForce RTX 5070 SUPER Comparison

Intel Arc Pro B65 and NVIDIA GeForce RTX 5070 SUPER represent two distinct approaches to GPU design within the same 5 nm TSMC process node. The data shows a clear split in capabilities, with the RTX 5070 SUPER leading in raw compute and the Arc Pro B65 offering a substantial memory capacity advantage. The recorded specifications indicate that these cards target different workload profiles despite sharing a PCIe 5.0 x16 interface and similar API support.

Where Each One Wins

The Intel Arc Pro B65 wins decisively in memory capacity, offering 32 GB of GDDR6 across a 256-bit bus. This contrasts sharply with the RTX 5070 SUPER's 18 GB of GDDR7 on a 192-bit interface. For workloads that require large datasets resident in VRAM, such as certain rendering scenes, machine learning inference batches, or large frame buffers, the Arc Pro B65 provides 77.8% more memory. The RTX 5070 SUPER counters with higher memory bandwidth, 672.0 GB/s versus 608.0 GB/s, a 10.5% advantage that benefits streaming textures and compute kernels.

The RTX 5070 SUPER wins in every compute throughput metric. Its FP32 rate of 32.15 TFLOPS is 2.6 times the Arc Pro B65's 12.29 TFLOPS. The NVIDIA card also doubles FP16 throughput at 32.15 TFLOPS (1:1 ratio) compared to Intel's 24.58 TFLOPS (2:1 ratio), meaning the RTX card maintains full rate even when FP16 is used. Texture rate favors NVIDIA at 502.4 GTexel/s versus 384.0 GTexel/s, a 30.8% lead. Pixel rates are closer, with NVIDIA at 201.0 GPixel/s versus Intel's 192.0 GPixel/s, a 4.7% margin.

The RTX 5070 SUPER also leads in shader resources, with 6400 shading units, 200 TMUs, 50 RT cores, and 200 tensor cores. The Arc Pro B65 has 2560 shading units, 160 TMUs, 80 ROPs, and 20 RT cores, with no tensor core count listed. The RTX card's 4x tensor core count and 2.5x RT core count suggest a stronger position for ray tracing and AI-accelerated workloads, though the Arc Pro B65 still supports DirectX 12 Ultimate.

Architecture Differences

The two GPUs derive from fundamentally different architectures. Intel uses Xe2-HPG, the second-generation high-performance graphics architecture, built on the BMG-G21 chip. NVIDIA uses Blackwell 2.0 with the GB205 die. Both are fabricated by TSMC on a 5 nm process, but the transistor counts diverge sharply: the RTX 5070 SUPER packs 31,100 million transistors on a 263 mm² die, while the Arc Pro B65 contains 19,600 million transistors on a slightly larger 272 mm² die. Transistor density favors NVIDIA at 118.3M per mm² versus Intel's 72.1M per mm².

Clock behavior differs as well. The Arc Pro B65 runs at a flat 2400 MHz for both base and boost, suggesting a locked frequency profile. The RTX 5070 SUPER has a base clock of 2325 MHz and a boost of 2512 MHz, an 8% boost headroom. Memory clocks show the generational gap: Intel uses 2375 MHz (19 Gbps effective) GDDR6, while NVIDIA uses 1750 MHz (28 Gbps effective) GDDR7. The newer memory standard achieves higher bandwidth despite a narrower bus.

Power and physical specifications separate the cards further. The Arc Pro B65 has a 200 W TDP with a single 8-pin connector and a suggested 550 W PSU. The RTX 5070 SUPER draws 275 W via a single 16-pin connector, with no suggested PSU listed. Both are dual-slot cards, but dimensions are only recorded for the RTX model at 245 mm length, 115 mm height, and 40 mm width. Display outputs differ: Intel provides 4x DisplayPort 2.1, while NVIDIA offers 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Head-to-Head Benchmarks

The only recorded benchmark in the database is 3DMark Steel Nomad DX12, where the RTX 5070 SUPER scores 2690 points. This places it in the 18th percentile among all GPUs. The nearest rivals show a tight cluster: NVIDIA Quadro K1100M at 2664 points (1% delta), NVIDIA GeForce GT 1030 at 2662 points (1.1% delta), Intel Arc Pro B50 at 2660 points (1.1% delta), and NVIDIA GeForce GT 440 at 2645 points (1.7% delta). No head-to-head benchmark results exist between the Arc Pro B65 and the RTX 5070 SUPER, and the Arc Pro B65 has no individual benchmark scores or rival listings in the database.

The RTX 5070 SUPER's 2690 score sits just 1% above the Quadro K1100M, a mobile workstation card from a different era. This indicates that the Steel Nomad workload may not stress the RTX card's full compute resources, or that the benchmark is particularly sensitive to certain bottlenecks. The 18th percentile ranking suggests that most GPUs in the database outperform it on this specific test, which is unusual given the card's raw specifications. The Arc Pro B65's 50th percentile ranking, while lacking a concrete score, positions it as a median performer across all recorded GPUs.

The lack of head-to-head data means comparisons must rely on specification-level analysis. The RTX 5070 SUPER's 32.15 TFLOPS FP32 versus 12.29 TFLOPS for the Arc Pro B65 is a 161.5% advantage. Texture rate differences are similarly large. The Arc Pro B65's only clear specification wins are memory capacity (32 GB vs 18 GB) and a lower TDP (200 W vs 275 W). The Intel card also has a slightly higher base clock at 2400 MHz versus 2325 MHz, though boost clocks favor NVIDIA.

The Verdict

The recorded data indicates that the RTX 5070 SUPER is the stronger compute performer across nearly every measured specification. Its FP32 throughput, texture rate, pixel rate, and memory bandwidth all exceed the Arc Pro B65's figures. The tensor core count of 200 versus none listed, plus 50 RT cores versus 20, gives NVIDIA a clear advantage for AI and ray tracing workloads.

The Arc Pro B65 justifies its existence through memory capacity and efficiency. Its 32 GB frame buffer is 77.8% larger than the RTX card's 18 GB, which matters for applications that cannot fit working sets into smaller VRAM pools. The 200 W TDP is 27.3% lower than the RTX card's 275 W, and the Intel card uses a standard 8-pin connector rather than a 16-pin. The flat 2400 MHz clock profile may indicate more predictable performance scaling.

The 50th percentile ranking for the Arc Pro B65 versus the 18th percentile for the RTX 5070 SUPER in the database suggests that the Intel card is a more median performer across all GPU tests, while the NVIDIA card's recorded benchmark is comparatively weak. However, with no head-to-head benchmark data and only one recorded test for the RTX card, the specification sheet remains the primary comparison tool.

Users requiring maximum compute throughput and modern AI features should select the RTX 5070 SUPER. Users needing maximum memory capacity with lower power draw should select the Arc Pro B65. The 32 GB GDDR6 configuration is unique in this comparison and cannot be matched by the RTX card's 18 GB GDDR7. Both cards support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so API compatibility does not differentiate them. The RTX 5070 SUPER's release date of 2025-12-31 precedes the Arc Pro B65's 2026-03-31, but both are listed as active production.
