Intel Arc Pro B65 vs NVIDIA GeForce RTX 4070 GDDR6 Comparison

Intel Arc Pro B65 and NVIDIA GeForce RTX 4070 GDDR6 occupy different corners of the GPU market, yet both carry 200 W TDP ratings and dual-slot designs. The Intel part is a workstation-oriented Battlemage Pro product built for compute and memory-heavy tasks, while the NVIDIA card is a mainstream GeForce 40-series part aimed at gaming and general rasterization. The database records no direct head-to-head benchmark between the two, so this analysis relies on the specification sheets, the lone 3DMark Steel Nomad DX12 score for the RTX 4070, and the recorded performance percentile positions.

Architecture Differences

The two GPUs stem from fundamentally different architectures. Intel uses Xe2-HPG, the architecture behind the Battlemage Pro Series, implemented on a 5 nm TSMC process. The chip is designated BMG-G21, and the full part carries 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1M per mm². NVIDIA’s RTX 4070 GDDR6 uses Ada Lovelace, built on the same 5 nm TSMC node, but the AD104 chip contains 35,800 million transistors on a larger 294 mm² die. That results in a substantially higher density of 121.8M per mm².

The compute resource distribution differs sharply. The Arc Pro B65 has 2560 shading units, 160 texture mapping units, and 80 render output units. It also includes 20 ray tracing cores. The RTX 4070 GDDR6 carries 5888 shading units, 184 TMUs, and 64 ROPs, plus 46 ray tracing cores and 184 tensor cores. NVIDIA’s card has more than double the shading units and more than double the RT cores, while Intel has more ROPs. Tensor cores are absent from the Intel specification sheet, which means the Arc Pro B65 lacks dedicated tensor hardware, while the RTX 4070 GDDR6 includes them for AI acceleration.

Clock behavior shows Intel’s part running at a flat 2400 MHz for both base and boost, with no game clock listed. The NVIDIA card has a 1920 MHz base clock and a 2475 MHz boost clock. That gives the RTX 4070 GDDR6 a 75 MHz higher maximum boost, but the Intel card maintains a constant frequency. Memory clocks also differ: the Arc Pro B65 runs at 2375 MHz with 19 Gbps effective, while the RTX 4070 GDDR6 runs at 2500 MHz with 20 Gbps effective. Despite the higher memory clock on the NVIDIA card, the wider 256-bit bus on Intel yields higher total bandwidth.

The power delivery and interface footprints are similar in some respects. Both cards have a 200 W TDP and require a 550 W suggested PSU. The Arc Pro B65 uses a single 8-pin power connector, while the RTX 4070 GDDR6 uses a single 16-pin connector. Both are dual-slot designs. The bus interface differs: PCIe 5.0 x16 for Intel versus PCIe 4.0 x16 for NVIDIA. Display outputs also diverge. The Arc Pro B65 offers four DisplayPort 2.1 outputs, while the RTX 4070 GDDR6 provides one HDMI 2.1 and three DisplayPort 1.4a outputs. The Intel card supports the newer DisplayPort standard across all four outputs.

API support is identical on paper: both list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The production status separates them further, with Intel Active and NVIDIA End-of-life. The RTX 4070 GDDR6 has a predecessor in GeForce 30 and a successor in GeForce 50. The Arc Pro B65 lists no predecessor or successor in the database.

Where Each One Wins

The Intel Arc Pro B65 wins on memory capacity and bandwidth. It provides 32 GB of GDDR6 across a 256-bit bus, which is 20 GB more than the RTX 4070 GDDR6’s 12 GB. Bandwidth favors Intel at 608.0 GB/s versus 480.0 GB/s. This makes the Arc Pro B65 better suited for workloads that demand large data sets resident in VRAM, such as professional visualization, large model inference, or high-resolution texture-heavy rendering. The 80 ROPs also give Intel a higher pixel rate of 192.0 GPixel/s, compared to 158.4 GPixel/s on the NVIDIA card. That indicates faster fill-rate operations for pixel-bound tasks.

The NVIDIA GeForce RTX 4070 GDDR6 wins on raw shading throughput and feature breadth. Its 5888 shading units deliver 29.15 TFLOPS of FP32 compute, more than double the 12.29 TFLOPS on the Arc Pro B65. FP16 performance is also higher: 29.15 TFLOPS on NVIDIA versus 24.58 TFLOPS on Intel. NVIDIA’s 184 tensor cores add AI acceleration, which Intel lacks entirely. The texture rate favors NVIDIA as well, 455.4 GTexel/s versus 384.0 GTexel/s. For gaming, the RTX 4070 GDDR6 has more RT cores (46 versus 20) and a higher boost clock (2475 MHz versus 2400 MHz), which should translate to better ray-traced and general rasterized performance.

The RTX 4070 GDDR6 also has a recorded benchmark score, while the Arc Pro B65 has none in the database. That single 3DMark Steel Nomad DX12 result of 4334.5 sits near a cluster of low-end integrated and mobile parts, which suggests that the recorded score may not reflect the NVIDIA card’s typical performance class, but it is the only quantitative comparison available. The Arc Pro B65 has no benchmark entries, so its percentile and average score are both zero in the database. That absence means any performance comparison must be inferred from specifications rather than direct measurements.

Identical fields include TDP (200 W), suggested PSU (550 W), slot width (dual-slot), process node (5 nm), foundry (TSMC), memory type (GDDR6), DirectX version (12 Ultimate 12_2), OpenGL version (4.6), and Vulkan version (1.4).

Head-to-Head Benchmarks

No direct head-to-head benchmark results exist in the database. The headToHeadBenchmarks array is empty, and the win counts for both items are zero. The only quantitative performance data comes from the RTX 4070 GDDR6’s 3DMark Steel Nomad DX12 score of 4334.5 points. That score places the card at the 25th percentile among all GPUs in the database. Its nearest rivals, as recorded, are all low-end parts: the Intel Iris Pro Graphics 5200 scores 4360, which is 0.6% above the RTX 4070 GDDR6. The NVIDIA GeForce 930M scores 4388, 1.2% higher. The AMD FirePro W2100 scores 4295, 0.9% below. The NVIDIA GeForce GTX 460M scores 4282, 1.2% below. The RTX 4070 GDDR6 sits within a narrow 1.2% band of these four entries, indicating that the recorded benchmark result does not distinguish the card from much older or weaker hardware.

The Arc Pro B65 has no benchmark entries in the database. Its percentile is listed as 50, which places it at the median of all GPUs, but this figure exists without any supporting score. The average benchmark score is zero. Without recorded test data, the Intel card’s performance cannot be compared numerically to the RTX 4070 GDDR6. The specification sheet shows a significant gap in shading power: NVIDIA’s 29.15 TFLOPS FP32 is roughly 2.37 times the Intel part’s 12.29 TFLOPS. Texture rate also favors NVIDIA by about 18.6%. Pixel rate favors Intel by about 21.2%. Memory bandwidth favors Intel by about 26.7%. These aggregate numbers suggest a tradeoff: NVIDIA has more compute and texture throughput, Intel has more fill rate and memory throughput.

The RTX 4070 GDDR6’s low percentile (25) and its proximity to ancient integrated graphics in the nearest rivals list may indicate that the single benchmark score is an outlier or that the test environment was unusual. The database records no other benchmark results for this card, so the 4334.5 score stands alone. The Arc Pro B65 lacks any such score, which means the only definitive comparison points are the specification differences listed above. In terms of recorded data, the RTX 4070 GDDR6 has a measurable benchmark result and a percentile, while the Arc Pro B65 has neither a score nor a rival list. The Intel card’s percentile of 50 is derived from all GPUs, but with no corresponding benchmark, that figure remains unverified by direct performance tests.
