Intel Arc Pro B70 vs NVIDIA GeForce RTX 4090 D Comparison

The Verdict

The database records a stark contrast between these two accelerators. The NVIDIA GeForce RTX 4090 D, with an average benchmark score of 178,050, sits at the 98th percentile of all GPUs, placing it among the top tier of recorded hardware. The Intel Arc Pro B70, by contrast, holds the 50th percentile with an average benchmark score of zero, indicating no recorded performance data in the current database. For any compute, rendering, or high-performance workload, the RTX 4090 D is the only choice supported by measured results. The Arc Pro B70 is a 2026 release with a 949 USD launch MSRP, while the RTX 4090 D launched in December 2023 at 1,599 USD; the database shows the RTX 4090 D is now end-of-life, with the GeForce 50 series as its successor. The Arc Pro B70 should only be considered by users who require its specific feature set, 32 GB memory capacity, or lower power envelope, as no benchmark data supports a performance verdict in its favor.

Architecture Differences

The two cards come from different architectural generations and design philosophies. The Intel Arc Pro B70 uses the BMG-G31 chip built on the Xe2-HPG architecture, part of the Battlemage Pro Series, fabricated on a 5 nm process at TSMC. The NVIDIA GeForce RTX 4090 D uses the AD102 chip on the Ada Lovelace architecture, also on a 5 nm TSMC process, and belongs to the GeForce 40-series generation. Intel's die measures 368 mm², while NVIDIA's is substantially larger at 609 mm², with the NVIDIA chip containing 76,300 million transistors and a transistor density of 125.3M per mm². Intel does not disclose transistor counts for its chip.

The compute resources differ dramatically. The RTX 4090 D packs 14,592 shading units, 456 texture mapping units, 176 raster output units, 114 ray tracing cores, and 456 tensor cores. The Arc Pro B70 offers 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores, with no tensor core equivalent listed. This results in a peak FP32 throughput of 73.54 TFLOPS for NVIDIA versus 22.94 TFLOPS for Intel, a 3.2x advantage for the RTX 4090 D. The FP16 figures show an even more telling split: NVIDIA achieves 73.54 TFLOPS at 1:1 ratio, while Intel manages 45.88 TFLOPS at a 2:1 ratio, meaning the NVIDIA card does not rely on packed math to reach its number.

Memory architecture also diverges. The Arc Pro B70 uses 32 GB of GDDR6 on a 256-bit bus with 608.0 GB/s of bandwidth and a 19 Gbps effective memory clock. The RTX 4090 D uses 24 GB of GDDR6X on a 384-bit bus, delivering 1.01 TB/s of bandwidth at 21 Gbps effective. NVIDIA's memory subsystem offers 66% more bandwidth despite 8 GB less capacity, a trade-off that favors throughput-heavy workloads on the NVIDIA side and capacity-heavy workloads on the Intel side.

Clock behavior differs as well. Both cards share a 2280 MHz base clock, but the Intel card boosts to 2800 MHz while the NVIDIA card boosts to 2520 MHz. The Intel card draws 230 W with a single 8-pin connector and a 550 W suggested PSU, while the NVIDIA card draws 425 W with a 16-pin connector and an 800 W suggested PSU. Physical dimensions reinforce this split: the Arc Pro B70 is a dual-slot card at 267 mm long, 110 mm tall, and 39 mm wide, while the RTX 4090 D is a triple-slot card at 304 mm, 137 mm, and 61 mm. Interface support also differs: Intel uses PCIe 5.0 x16 with 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs, while NVIDIA uses PCIe 4.0 x16 with 1x HDMI 2.1 and 3x DisplayPort 1.4a. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the Arc Pro B70 and the RTX 4090 D. However, the RTX 4090 D has three recorded benchmark scores that establish its performance tier. In 3DMark Steel Nomad DX12, it scores 8,587. In Geekbench OpenCL, it scores 278,621. In Geekbench Vulkan, it scores 246,941. These results place the RTX 4090 D at the 98th percentile of all GPUs, with an average benchmark score of 178,050.

The nearest rivals in the database provide context for the RTX 4090 D's standing. The NVIDIA RTX PRO 5000 Blackwell scores 182,109, which is 2.2% higher than the RTX 4090 D. The NVIDIA A100 SXM4 80 GB scores 183,725, 3.1% higher. The NVIDIA RTX 5000 Ada Generation scores 184,664, 3.6% higher. The NVIDIA A100 SXM4 40 GB scores 187,147, 4.9% higher. This means the RTX 4090 D trails the nearest recorded rivals by margins between 2.2% and 4.9%, placing it just below the top of the measured performance hierarchy. The Arc Pro B70 has no benchmark scores, no nearest rivals, and a zero average score, so no comparative percentage can be derived from the data.

The performance gap between the two cards is best expressed through the raw compute specifications. The RTX 4090 D delivers 73.54 TFLOPS FP32 versus 22.94 TFLOPS for the Arc Pro B70, a 50.6 TFLOPS difference. Texture rate favors NVIDIA at 1,149.1 GTexel/s versus 716.8 GTexel/s, a 60% advantage. Pixel rate favors NVIDIA at 443.5 GPixel/s versus 358.4 GPixel/s, a 24% advantage. These figures indicate that across raw throughput metrics, the RTX 4090 D leads by significant margins, though the Arc Pro B70's higher boost clock of 2800 MHz versus 2520 MHz suggests Intel designed for frequency efficiency rather than brute compute scale.

Where Each One Wins

The NVIDIA GeForce RTX 4090 D wins in every measured performance category and in all recorded benchmark results. Its 73.54 TFLOPS FP32 throughput, 1,149.1 GTexel/s texture rate, and 443.5 GPixel/s pixel rate dwarf the Intel Arc Pro B70's corresponding figures of 22.94 TFLOPS, 716.8 GTexel/s, and 358.4 GPixel/s. The RTX 4090 D also leads in ray tracing resources with 114 RT cores versus 32, and in tensor core availability with 456 versus none. Its memory bandwidth of 1.01 TB/s exceeds Intel's 608.0 GB/s, and its 98th percentile standing with an average benchmark score of 178,050 confirms its position among the fastest recorded GPUs. For any workload where raw compute, rendering throughput, or ray tracing performance matters, the RTX 4090 D is the clear winner based on the data.

The Intel Arc Pro B70 wins in specific specification categories that do not involve measured performance. It offers 32 GB of memory versus 24 GB, a 33% capacity advantage for large datasets or multi-model workloads. It has a higher boost clock at 2800 MHz versus 2520 MHz, a 11% frequency advantage. It uses PCIe 5.0 x16 rather than PCIe 4.0 x16, doubling the theoretical interface bandwidth. It supports DisplayPort 2.1 outputs versus DisplayPort 1.4a, enabling higher display refresh rates and resolutions. It draws 230 W versus 425 W, a 45% lower power requirement, and fits in a dual-slot form factor versus triple-slot, easing installation in compact systems. Its 949 USD launch MSRP is lower than NVIDIA's 1,599 USD, though pricing comparisons do not factor into performance analysis.

The recorded data shows no benchmark wins for either card in a head-to-head comparison, as the database lists zero wins for both. The RTX 4090 D's three individual benchmark scores, 8,587 in 3DMark Steel Nomad DX12, 278,621 in Geekbench OpenCL, and 246,941 in Geekbench Vulkan, are the only measured performance results available. The Arc Pro B70 has no recorded scores, so no empirical comparison can be made. Users requiring validated performance should select the RTX 4090 D; users requiring maximum memory capacity, lower power draw, newer display outputs, or PCIe 5.0 connectivity may choose the Arc Pro B70 based on its listed specifications, accepting that no benchmark data supports its performance claims.
