Intel Arc Pro B65 vs NVIDIA B300 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct benchmark comparisons between the Intel Arc Pro B65 and the NVIDIA B300. Both products have an average benchmark score of 0, and both sit at the 50th percentile among all GPUs in the database. The head-to-head benchmark matrix is empty, meaning no standardized tests have been run that place these two cards in the same workload suite.

Without benchmark scores, the data cannot show which product wins in specific applications such as rasterization, ray tracing, or compute workloads. The absence of scores is itself informative: these are not directly comparable consumer or workstation parts. The Intel Arc Pro B65 targets professional graphics with a 200 W power envelope and DisplayPort outputs, while the NVIDIA B300 is a 1400 W server accelerator with no display outputs. The database records zero wins for either side, so the head-to-head section must rely on architectural and specification analysis rather than measured performance.

The closest interpretable signal comes from raw compute specifications. The NVIDIA B300 delivers 76.99 TFLOPS of FP32 throughput, while the Intel Arc Pro B65 delivers 12.29 TFLOPS. That is a 6.27x gap in single-precision floating-point performance. In FP16, the difference is even larger: the B300 achieves 1,231.8 TFLOPS, while the Arc Pro B65 reaches 24.58 TFLOPS. The B300's FP16 figure is roughly 50x higher. These numbers are theoretical peak rates, not measured application performance, but they set clear expectations for compute-heavy workloads.

Memory bandwidth tells a similar story. The B300 has 4.10 TB/s of bandwidth from HBM3e, versus 608.0 GB/s from GDDR6 on the Intel card. That is a 6.74x advantage in raw memory throughput. The B300 also holds 144 GB of memory, compared to 32 GB on the Arc Pro B65. For workloads that scale with memory capacity, such as large model inference or data processing, the B300's advantage is substantial.

The Intel card counters in pixel throughput. The Arc Pro B65 achieves 192.0 GPixel/s, while the B300 achieves 48.77 GPixel/s. That is a 3.94x advantage for Intel in pixel fill rate. The texture rate also favors Intel on a per-unit basis: 384.0 GTexel/s versus 1,202.9 GTexel/s for NVIDIA, though the raw NVIDIA number is higher. The Intel card has 80 ROPs versus 24 on the B300, explaining the pixel rate advantage. This suggests the Arc Pro B65 is better suited for traditional graphics rendering pipelines, while the B300 is optimized for compute.

Architecture Differences

The two GPUs come from different design philosophies. The Intel Arc Pro B65 uses the BMG-G21 chip built on the Xe2-HPG architecture, part of the Battlemage Pro Series. It is manufactured on a 5 nm process at TSMC with 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1 million per square millimeter. The NVIDIA B300 uses the GB110 chip based on the Blackwell Ultra architecture, part of the Server Blackwell generation. It is also built on a 5 nm TSMC process but packs 104,000 million transistors. The B300's die size is not recorded, so density cannot be computed.

The Intel architecture includes 20 ray tracing cores, a feature the B300 does not list. The B300 instead has 592 tensor cores, while the Intel card lists none. This division is clear: Intel built for graphics acceleration with RT hardware, NVIDIA built for AI and tensor-heavy compute. The B300's shading unit count is 18,944, versus 2,560 on the Intel card. Texture mapping units number 592 on NVIDIA and 160 on Intel. Raster operation units are the exception, with Intel at 80 and NVIDIA at 24.

Clock behavior differs substantially. The Intel card runs at a fixed 2400 MHz for both base and boost. The NVIDIA card has a base clock of 1665 MHz and a boost clock of 2032 MHz. Memory clocks also differ: Intel runs GDDR6 at 2375 MHz (19 Gbps effective), while NVIDIA runs HBM3e at 2000 MHz (8 Gbps effective). The memory bus width is 256 bits on Intel and 4096 bits on NVIDIA, which combined with the memory type explains the bandwidth gap.

The B300 uses an SXM Module slot width and has no display outputs, while the Intel card is dual-slot with four DisplayPort 2.1 outputs. The B300 lists no power connectors, while the Intel card uses a single 8-pin connector. Suggested PSU ratings are 550 W for Intel and 1800 W for NVIDIA. The B300's predecessor is recorded as Server Hopper, with Server Rubin as its successor. The Intel card has no predecessor or successor listed.

The Verdict

The data indicates two products with entirely different purposes. The Intel Arc Pro B65 is a professional graphics card: it has display outputs, a dual-slot design, a 200 W TDP, and a 550 W suggested PSU. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The NVIDIA B300 is a server compute accelerator: it has no display outputs, uses an SXM Module form factor, draws 1400 W, and lists no graphics API support. The B300's listed APIs are all null.

For graphics rendering, the Intel card wins on pixel fill rate (192.0 GPixel/s versus 48.77 GPixel/s) and has dedicated ray tracing cores. It also has a much lower power requirement, making it feasible for workstation builds with standard power supplies. The B300's 1400 W TDP and 1800 W suggested PSU place it in data center racks, not desktop workstations.

For compute, the NVIDIA card dominates in every relevant metric: FP32 (76.99 versus 12.29 TFLOPS), FP16 (1,231.8 versus 24.58 TFLOPS), memory capacity (144 GB versus 32 GB), memory bandwidth (4.10 TB/s versus 608.0 GB/s), shading units (18,944 versus 2,560), and tensor cores (592 versus none). The B300 is the clear choice for AI training, inference, or scientific simulation.

The database shows zero benchmark wins for either product, but the specification deltas are decisive. A user needing a display-capable GPU for professional graphics software should select the Intel Arc Pro B65. A user deploying a server accelerator for large-scale compute should select the NVIDIA B300. They are not alternatives; they are different categories.

Where Each One Wins

The Intel Arc Pro B65 wins in graphics-oriented metrics. Its pixel rate of 192.0 GPixel/s is nearly four times the B300's 48.77 GPixel/s. It has 80 ROPs versus 24, which supports higher fill rates in traditional rendering. The inclusion of 20 ray tracing cores gives it dedicated hardware for ray-traced effects, a feature the B300 does not list. The Intel card also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the B300 lists no graphics API support. Its 200 W TDP and single 8-pin connector make it compatible with typical workstation power setups. The dual-slot design and four DisplayPort outputs confirm its role as a display-capable graphics solution.

The NVIDIA B300 wins in every compute and memory metric. Its FP32 throughput of 76.99 TFLOPS is 6.27x higher than Intel's. Its FP16 throughput of 1,231.8 TFLOPS is roughly 50x higher. The 592 tensor cores provide dedicated hardware for AI workloads. Memory capacity of 144 GB is 4.5x the Intel card's 32 GB. Memory bandwidth of 4.10 TB/s is 6.74x higher.

The table shows shared traits: both use a 5 nm TSMC process and PCIe 5.0 x16 interfaces. Every other major specification diverges. The Intel card favors graphics throughput with higher pixel rate, more ROPs, and display support. The NVIDIA card favors compute with more transistors, shading units, tensor cores, memory, and bandwidth. The transistor count difference is notable: the B300 packs 5.3x more transistors than the Arc Pro B65, reflecting its server-scale design.
