A: The B300 SXM6 AC scores 369831, which is 7% higher than the NVIDIA B200 (345482), 10.4% higher than the NVIDIA H200 NVL (334891), 16.3% higher than the AMD Instinct MI300X (317994), and 25% higher than the NVIDIA L40S (295763).

Where Each One Wins

The NVIDIA B300 SXM6 AC dominates in raw compute and memory bandwidth, which positions it for massive parallel workloads. Its 76.99 TFLOPS FP32 performance and 8.19 TB/s memory bandwidth are figures that dwarf the Intel Arc Pro B70's 22.94 TFLOPS and 608.0 GB/s. The B300 SXM6 AC also carries 18944 shading units, 592 tensor cores, and 208,000 million transistors, making it a data-center-scale processor for AI training, inference, and high-performance computing.

The Intel Arc Pro B70 wins in areas that matter for professional workstation use. It offers display outputs (1x HDMI 2.1a, 3x DisplayPort 2.1), which the B300 SXM6 AC lacks entirely. The Arc Pro B70 also has a much lower TDP at 230 W versus 1100 W, and a suggested PSU of 550 W versus 1500 W. Its dual-slot form factor and 8-pin power connector make it installable in conventional workstation chassis, whereas the SXM module requires a specialized server platform.

The Arc Pro B70 also supports the full graphics API stack: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B300 SXM6 AC records N/A for DirectX, OpenGL, and Vulkan, indicating it is not designed for conventional graphics rendering pipelines. For visualization, CAD, or any workload requiring a display output, only the Intel card is viable from the data.

Architecture Differences

The two GPUs represent entirely different architectural philosophies. The Intel Arc Pro B70 uses the Xe2-HPG architecture on the BMG-G31 chip, part of the Battlemage (Pro Series) generation. It is built on a 5 nm TSMC process with a die size of 368 mm². The B300 SXM6 AC uses the Blackwell Ultra architecture on the GB110 chip, from the Server Blackwell (Bxx) generation. It is also built on a 5 nm TSMC process but with a die size of 1628 mm², which is more than four times larger.

Transistor counts differ dramatically. The Intel chip's transistor count is listed as unknown, while the NVIDIA GB110 contains 208,000 million transistors with a transistor density of 127.8M per mm². The B300 SXM6 AC integrates 592 tensor cores, while the Arc Pro B70 has no tensor core count listed. Instead, the Intel card has 32 ray tracing cores, while the B300 SXM6 AC has no RT core count listed.

The shading unit counts reveal the scale gap: 18944 for NVIDIA versus 4096 for Intel. TMUs follow at 592 versus 256. A notable inversion appears in ROPs: the Intel card has 128 ROPs, while the NVIDIA card has only 24. This suggests the Intel architecture prioritizes pixel output for graphics workloads, while the NVIDIA design focuses its silicon on compute and tensor operations. The pixel rate confirms this: 358.4 GPixel/s for Intel versus 48.77 GPixel/s for NVIDIA. The texture rate, however, favors NVIDIA at 1,202.9 GTexel/s versus 716.8 GTexel/s.

The FP16 capability also differs in ratio. The Intel Arc Pro B70 achieves 45.88 TFLOPS FP16 at a 2:1 ratio relative to FP32. The NVIDIA B300 SXM6 AC achieves 76.99 TFLOPS FP16 at a 1:1 ratio, meaning it does not rely on a reduced-precision path for its half-precision throughput.

Specification Differences

The two products differ across nearly every measurable specification. Clock speeds show Intel running higher: base 2280 MHz and boost 2800 MHz versus NVIDIA's base 1665 MHz and boost 2032 MHz. Memory clocks likewise favor Intel at 2375 MHz (19 Gbps effective) versus NVIDIA's 2000 MHz (8 Gbps effective), though the memory type and bus width make NVIDIA's aggregate bandwidth far superior.

Memory capacity is 288 GB of HBM3e for NVIDIA versus 32 GB of GDDR6 for Intel. The bus width is 8192 bit versus 256 bit. Bandwidth is 8.19 TB/s versus 608.0 GB/s. The TDP is 1100 W versus 230 W. The suggested PSU is 1500 W versus 550 W.

Form factor and power delivery are distinct: the B300 SXM6 AC is an SXM module with no power connector listed, while the Arc Pro B70 is a dual-slot card with a 1x 8-pin connector. The bus interface differs as well: PCIe 6.0 x16 for NVIDIA, PCIe 5.0 x16 for Intel.

Display outputs are exclusive to Intel: 1x HDMI 2.1a and 3x DisplayPort 2.1. The NVIDIA module has no outputs. API support is exclusive to Intel as well, with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4; NVIDIA lists N/A for all three.

Dimensions are only recorded for the Intel card: 267 mm length, 110 mm height, 39 mm width. The NVIDIA module has no recorded dimensions. The release dates differ by roughly six months: 2025-09-10 for NVIDIA, 2026-03-25 for Intel. The B300 SXM6 AC lists a predecessor (Server Hopper) and successor (Server Rubin), while the Arc Pro B70 lists none. The Intel card has a launch MSRP of 949 USD; the NVIDIA module has no launch MSRP recorded.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two GPUs. The only benchmark score available belongs to the NVIDIA B300 SXM6 AC: 369831 on Geekbench OpenCL. This places it in the 100th percentile of all GPUs, meaning it outperforms every other recorded GPU in that test. The Intel Arc Pro B70 has no benchmark entries and an average benchmark score of 0, sitting at the 50th percentile.

Without direct comparisons, the nearest rival data for the B300 SXM6 AC provides context. It beats the NVIDIA B200 by 7%, the NVIDIA H200 NVL by 10.4%, the AMD Instinct MI300X by 16.3%, and the NVIDIA L40S by 25%. These deltas show a consistent performance ladder where the B300 SXM6 AC sits at the top of the database's recorded results.

The FP32 compute figures offer another comparative angle. The B300 SXM6 AC's 76.99 TFLOPS is 3.36 times the Arc Pro B70's 22.94 TFLOPS. The memory bandwidth gap is even larger: 8.19 TB/s is roughly 13.5 times 608.0 GB/s. The shading unit count favors NVIDIA by a factor of 4.6, and the texture rate favors NVIDIA by a factor of 1.68.

However, the pixel rate favors Intel by a factor of 7.35 (358.4 GPixel/s versus 48.77 GPixel/s), and the ROP count favors Intel by a factor of 5.33. These wins indicate that for rasterization-heavy tasks, the Intel architecture is tuned differently, even if its absolute compute ceiling is lower.

The clock speeds also tell a story. The Intel card boosts to 2800 MHz, which is 37.8% higher than the NVIDIA card's 2032 MHz boost. This higher clock partially explains why the Intel card achieves competitive pixel throughput despite having far fewer shading units.

The Verdict

The data presents two specialized tools rather than direct competitors. The NVIDIA B300 SXM6 AC is a server accelerator with the highest recorded Geekbench OpenCL score in the database (369831, 100th percentile). It delivers 76.99 TFLOPS FP32, 8.19 TB/s memory bandwidth, 288 GB of HBM3e, and 592 tensor cores. Its nearest rivals trail by 7% to 25%, confirming its position at the top of the recorded performance hierarchy. Any workload that can utilize massive parallel compute, large memory pools, or tensor operations belongs to this card.

The Intel Arc Pro B70 is a professional workstation GPU with display outputs, full graphics API support (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), and a 230 W TDP that fits into a dual-slot, 8-pin powered chassis. Its 32 GB of GDDR6 memory and 608.0 GB/s bandwidth are modest next to the NVIDIA module, but its 358.4 GPixel/s pixel rate and 128 ROPs indicate a design aimed at graphics output and rendering tasks. The 2800 MHz boost clock is the highest clock speed recorded between the two.

The choice depends entirely on the workload. For compute, AI, or HPC in a server context, the B300 SXM6 AC is the only option with recorded benchmark validation, and it outperforms every rival in the database. For a workstation that must drive displays and run graphics APIs, the Arc Pro B70 is the only option with those capabilities. The B300 SXM6 AC has no display outputs and no API support, while the Arc Pro B70 has no benchmark scores and a much lower compute ceiling. Neither product can substitute for the other based on the recorded data.
